Answer:
The percent composition is 21% N, 6% H, 24% S and 49% O.
Explanation:
1st) The molar mass of (NH4)2SO4 is 132g/mol, and it represents the 100% of the mass composition.
In 1 mole of (NH4)2SO4, there are:
- 2 moles of N.
- 8 moles of H.
- 1 mole of S.
- 4 moles of O.
2nd) It is necessary to calculate the mass of each element, multiplying its molar mass by the number of moles:
- 2 moles of N (14g/mol) = 28g
- 8 moles of H (1g/mol) = 8g
- 1 mole of S (32g/mol) = 32g
- 4 moles of O (16g/mol) = 64g
3rd) With a mathematical rule of three we can calculate the percent composition of each element in the molecule of (NH4)2SO4:
In this case, we can calculate the percent composition of Oxygen by subtracting the other percentages, since the total must be 100%.
So, the percent composition is 21% N, 6% H, 24% S and 49% O.
Answer:
the newest strategy on get hurt a nuclear warhead we store any chemical agents is to actually dispose of them area of water lighten them off where there is no land animals or any other living breathing animals mammals plantations therefore the correct waste should be disposed of properly by either nuking it in like a loner thing when we burn bodies or in an isolated area where it cannot harm fellow American people animals tree life they should be disposed of properly properly by scientists that have corrected it and know how to break it down there for non giving harmful bacteria land my phone is going to die over Zone and taking away our atmosphere

Explanation:
The reaction to be considered is shown below;
H2CO3<------->CO2 + H2O
We know that when a constraint such as a sudden change in concentration, pressure or temperature is imposed on a reaction system in equilibrium, the system has to adjust itself by shifting in a particular direction in order to cancel the constraint.
Now, if we remove CO2, the equilibrium position must shift to the right by the decomposition of more H2CO3 to establish equilibrium again.

Answer:
1.602 moles CO
Explanation:
To convert from liters to moles, divide by 22.4:
35.88 L / 22.4 = 1.602 moles CO
