Answer:
There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout. The most common type of homogenous mixture is a solution, which can be a solid, liquid, or gas.
Hope this helped :)
Answer : The mass of occupy 30.3 L under the same conditions will be, 24.9 grams.
Explanation :
First we have to calculate the moles of
Now we have to calculate the moles of in 30.3 L by using Avogadro's law.
Avogadro's law : It is defined as the volume of gas is directly proportional to the number of moles of gas at constant pressure and temperature.
or,
where,
= initial volume of gas = 6.21 L
= final volume of gas = 30.3 L
= initial moles of gas = 0.16 mol
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
Now we have to calculate the mass of
Molar mass of = 32 g/mol
Therefore, the mass of occupy 30.3 L under the same conditions will be, 24.9 grams.
2H2S + 3O2 → H2O + SO2
We have 4 H on the left and 2 on the right
2 S on the left and 1 on the right
6 O on the left and 3 on the right
We need to multiply everything on the right by 2
Add a coefficient 2 before H2O and a 2 before SO2.
2H2S + 3O2 → 2H2O + 2SO2
4H 4H
2S = 2S
6O =2O
