The answer is A) each side of the equations is divided by the number of moles.
The combined gas law equation
P1V1/T1 = P2V2/T2
becomes
P1V1/n1T1 = P2V2/n2T2
with the addition of Avogadro's law relating volume and number of moles of a gas.This modification is when the number of moles of gas in a sample is allowed to change in addition to pressure, temperature and volume. This also means that pressure multiplied by the volume and divided by the product of the number of moles and temperature is a constant:
PV/nT = constant
which if written in the form PV = nRT is the ideal gas law equation where R is the gas constant.
Four grams of calcium must be combined with phosphorus to form one mole of the compound Ca3P2
Oxidation is the loss of electrons. Reduction is the gain of electrons. The oxidizing agent is reduced. The reducing agent is oxidized. Cu goes from 0 to +2, it lost electrons S went from +6 to +4, it gained electrons I went from 0 to +5, it lost electrons N went from +5 to +4, it gained electrons.
Tantalum (Ta), Osmium (Os) and Rhodium (Rh) are metals.
<u>Explanation</u>:
- Metals are good conductors of heat and electricity and they can be hammered into sheets (malleable).Mainly most of them are solids. Ta, Os and Rh are all metals with a same platinum group.
- Tantalum (Ta) with a atomic number 73 is a lustrous transition metal which is highly corrosive resistant. It is mainly used in making electronic equipment.
- Rhodium (Rh) is a chemical element with atomic number 45 is a rare, silvery white,hard and corrosive resistant metal. Osmium (Os) with a atomic number 76 is a hard, brittle bluish-white transition metal.
Answer:
Mixture
Explanation:
Air is a mixture, meaning it can be separated into its components without a chemical reaction taking place. In this case, it is a mixture of gases.
