Answer:
The answer is "Option C".
Explanation:
Given equation:
Has been the reactant which is limited since the two experiments are equal to for relationship between stress amounts.
Limiting reactant =
Hello!
How many molecules are in 30 liters of methane (CH4) at STP ?
We have the following information:
Knowing that by Avogadro's Law for each mole of substance we have 6.02 * 10²³ molecules, it is known that in STP (Standard Temperature and Pressure) one mole of any gas equals 22.4 L, then:
22.4 L ----------------- 6.02*10²³ molecules
30 L -------------------- y molecules
multiply the means by the extremes
Answer:
8.0625*10²³ molecules of methane

Answer:
B. particles in an object move faster
Explanation:
At higher temperatures, particles in an object moves faster.
Temperature is the degree of hotness or coldness of a body.
- At higher temperature, the substance is very hot.
- Temperature is related to the heat energy content of a body
- As the temperature increases, the average kinetic energy of the particles of system increases more and more.
- This is in compliance with the kinetic molecular theory of matter.
- Therefore, at higher temperatures, particles in an object move faster.
The answer is 4.0 moles of magnesium
because...
..
...4.0mol Makmol O2 =3.0mol O2
Answer:
Evaporation is a type of vaporization of a liquid that only occurs on the liquid's surface. Usually, the molecules in a glass of water do not have enough heat energy to escape from the liquid. With sufficient heat, however, the liquid would quickly turn into vapor.
