Answer:
The answer is: 0,13 moles of CO2
Explanation:
We use the formula PV=nRT. The conditions STP are 1 atm of pressure and 273K of temperature:
PV=nRT n=PV/RT
n=1 atm x 2,8 L/ 0,082 l atm/K mol x 273K
n= 0,125078173 mol
Hello!
To find the mass in grams of 2.00 * 10²³ molecules of F₂ you'll need to apply the
Avogadro's number, which tells the number of molecules in a mol of a substance, and the
Molar Mass, which tells the weight of a mole of a substance. These two quantities are used in the following conversion factor:
![2,00*10^{23} moleculesF_2* \frac{1 mol F_2}{6,02*10^{23} moleculesF_2 }* \frac{37,997 g F_2}{1 mol F_2} \\ \\ =12,51 g F_2](https://tex.z-dn.net/?f=2%2C00%2A10%5E%7B23%7D%20moleculesF_2%2A%20%5Cfrac%7B1%20mol%20F_2%7D%7B6%2C02%2A10%5E%7B23%7D%20moleculesF_2%20%7D%2A%20%5Cfrac%7B37%2C997%20g%20F_2%7D%7B1%20mol%20F_2%7D%20%5C%5C%20%20%5C%5C%20%3D12%2C51%20g%20F_2%20)
So, the mass of 2.00 * 10²³ molecules of F₂ is
12,51 gHave a nice day!

Answer: enthalpy of reaction.
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like
and
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
Free energy is the amount of energy that can be converted into useful work.
Enthalpy of the reaction is the difference between the energy of products and the energy of reactants. it is either the heat released or absorbed during the reaction. It is either positive or negative.
