This video will go over how to read the periodic table (periodic table of elements) and determine if an element on the table of elements is a metal, nonmetal or metalloid. It is as easy as finding the “Staircase” on the periodic table. Any element to the left of the staircase is a metal, any element to the right of the staircase is a nonmetal and any element directly above or below the staircase is a metalloid. The exceptions are hydrogen and aluminum. Hydrogen is on the left of the staircase but it not a metal it is in fact a nonmetal. Aluminum is directly below the staircase but it is not a metalloid it is in fact a metal. Before you can learn more about the periodic table trends (periodic trends) such as atomic radius, Ionization energy trend etc. It is critical that you are able to identify metals, nonmetals and metalloids on the periodic table (periodic table of elements) so that you are able to predict periodic trends such as electronegativity trend, atomic radius trend etc. #Periodictable #Periodictableofelements #Tableofelements #Periodic #Theperiodictable #metals #nonmetals #metalloids #metal #nonmetal #metalloid Link to Full video is located below: https://youtu.be/OpjfStqHg0g?t=366 Good Luck and Good Chemistry!

Calculating calories is an important skill to master in chemistry. It is also a very easy to do! Heat energy is a measured in calories. A calorie is defined to be the heat required to raise the temperature of one gram of water by one degree Celsius. The energy in food items is stored in the chemical bonds. When these bonds break the energy in those bonds is liberated and transferred into the surroundings. Calories are measured in a device called a calorimeter. When a reaction is conducted in a calorimeter the amount of energy released in a chemical process can be measured by monitoring the change in temperature of the water in the calorimeter.

This video will go over the easy way to calculate density. Density is the relationship of mass to volume. Generally speaking the units for a solid or liquid object are grams per milliliter (mL) or grams (g) per centimeter cubed (cm3). The density of a gas is generally grams (g) per liter (L). This sort of question is typical on chemistry exams and you would do yourself a huge favor to be very familiar with these types of calculations and you can do well in chemistry! There are two methods to determine volume: direct measurement and volume by displacement. Direct measurement requires that there is a mathematical formula to calculate volume such as Volume = length x width x height (V = L x W x H). Density calculations are simple. Calculating density should not be intimidating. Performing a volume by displacement requires a volume measuring device such as a graduated cylinder with a known volume of water (initial volume Vi). The object of interest is submerged into the water. The water level will rise providing a new volume (final volume Vf). To determine the volume of the object (Vo or Vobject) = final volume (Vf) - initial volume (Vi). Density is mass divided by volume (D = m/v) Link to the full video is here: https://youtu.be/xz3OaY990yA?t=195 Good Luck and Good Chemistry!

Calculating molar mass is the focus of this video. It is critical that all chemistry student know how to calculate molar mass. Indeed, the calculation of molar mass is a fundamental problem in all chemistry classes. To calculate molar mass it is first necessary to know how to find the atomic mass of each element in a molecular formula. Remember the atomic masses of each and every element are found on the periodic table of the elements. Atomic mass and molar mass share the same value (number) but the units for molar mass are grams per mole (g/mole). Being able to calculate molar mass is an important skill in chemistry. The better you understand how to do this type of problem the easier a lot of other chemistry problems will be for you! Answers to end of video problems: Ca(OH)2 = 74.09 g/mole (NH4)2SO4 = 132.14 g/mole Check out this video for a problem that uses molar mass calculations to determine the molarity of a solution: https://youtu.be/Af7PgtIyJA0 Good Luck and Good Chemistry!

This video will demonstrate the reaction of simple candies with KClO4. This is an oxidation reaction / reduction reaction (REDOX reaction). Oxidation is the gain of oxygen, the loss of hydrogen or the loss of electrons. Reduction is the loss of oxygen, the gain of hydrogen or the gain of electrons. If a reagent is oxidizing it gains an oxygen and is said to be oxidized. If a reagent is reducing it is losing oxygen and is said to be reduced. In this reaction the oxidation chemistry involves sugar and the reduction chemistry involves potassium chlorate (KClO4). The sugar is oxidizing while the KClO4 is reducing. During your chemistry classes see if you can identify oxidation and reduction reaction and identify which reactants are going through an oxidation and which reactants are going through a reduction. This reaction generates KCl, CO2, H2O and a lot of heat! The sugar in the candies will burn with a pink flame as a result of the presence of the potassium ion (K+). #redox #gummybearexplosion #gummybearpotassiumchlorate #gummybearspotassiumchlorate #gummybearKClO4 #redoxreaction #oxidation #oxidize #oxidationis #oxidationchemistry #oxidationreaction #oxidizing #reducing #oxidationreduction #reductionchemistry #oxidationandreduction #oxidation&reduction #oxidationreductionreaction Like this video and subscribe to my channel! @All in with Dr Betts Leave a comment below!

The link to the full video is found here: https://youtu.be/xz3OaY990yA?t=451 Chemistry made easy… sounds too good to be true. Can chemistry made simple or chemistry made easy really be true? Yes! and this video will demonstrate to you how it can be accomplished. This is a minute lesson on how to use a graduated cylinder to measure volume of an irregularly shaped object. The technique being used is known as volume by displacement. This technique requires the user to add a known amount of water to a graduated cylinder. The amount of water used should be enough to submerge the irregularly shaped object, but not enough so as to exceed the capacity of the graduated cylinder. Once the water is in the graduated cylinder place the object careful into the water and measure the final volume. The final volume is the volume of the water plus the irregularly shaped object. It is important that you measure the initial and final volumes to the correct precision. That means you must be able to measure to the estimated digit if you are using an analog measuring device. The mass is usually given in the question but if not, mass is easily obtained by placing an irregularly shaped object on to a digital balance. Volume is obtained either by direct measurement or volume by displacement. Not as easy to get as mass but really not that hard. It really is chemistry made easy or if you would rather chemistry made simple! #density #density problem #volume #mass #collegechem #madeeasy #chemmadeeasy #chemistrymadeeasy #minutelesson #minutelessons #chemminutelesson #chemistryminutelessons Like this video and subscribe to my channel! @All in with Dr Betts Leave a comment below!

#measuring #graduated cylinder #nurse #chemistry #made easy This video will demonstrate to you how to use a graduated cylinder to measure volume to the correct number of significant figures. It is important that you are able to measure with the correct precision. This means you must be able to determine the estimated digit if you are using an analog measuring device. The estimated digit is often overlooked, but is absolutely required for a correct measurement to be obtained. In nursing you will often be required to take measurements. This means that you will be required on a daily bases to take measurements to the correct precision with the correct units. Measuring volume of only one measurement of many that can be done. If you are using an analog device the procedure to obtain the correct number of digits is always the same! Like this video and subscribe to my channel! @All in with Dr Betts Leave a comment below!

This video will demonstrate to the nursing student how to calculate molarity. Molarity is the relationship between the moles of a solute and the liters of a solution. Calculating molarity is as simple as dividing the moles of a solute by the liters of solution. The molarity formula is Molarity = grams or solute / liters of solution. The real complication for this type of problem is calculating moles of solute. However, you should not let that intimidate you. The moles of solute can be easily calculated by simply dividing the grams of solute by the molar mass of the solute. Of course, molarity problems can be further complicated by forcing the student to also calculate the molar mass of the solute from the molecular formula. Do not get discouraged! Molar mass can be easily calculated by adding up the molar masses of each element in the formula. For more on calculating molar mass please see the following video: https://youtu.be/G4Hmst4V-2I Molarity is an important concentration unit used in chemistry. The better you understand molarity the easier a lot of other chemistry problems will be for you! Please like this video and leave a comment below! It really helps and is so encouraging.
