Answer:
A. 650 g
Explanation:
The equation of the reaction is given as;
2 HgO(s) --> 2Hg(s) + O2(l)
From the reaction;
2 mol of HgO produces 1 mol of O2
x mol of HgO would produce 1.50 mol of O2
2 = 1
x = 1.5
Solving for x;
x = 1.5 * 2 / 1 = 3 mol
Converting to mass;
Mass = Number of moles * Molar mass
Mass = 3 mol * 216.59 g/mol
Mass = 649.77 g ≈ 650. g
Correct option is ;
A. 650 g
Answer:
0.423g
Explanation:
akording to mass = concetration x volume
A reaction between to acids
Answer:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Answer:
8.7 L
Explanation:
T2(V1/T1) = V2
417.15 K(6.2 L/296.45 K) = 8.7 L
Remember to almost always change celcius to kelvin. Also, this is part of Charle's Law (temp and volume are proportional, so if temp increaces so must the volume or vice versa). Lastly, Charle's Law has the formula of V1/T1 = V2/T2. I just rearranged it to go along with your problem. Hence, the T2(V1/T1) = V2
