This reason would mainly be because the "earth would have moderate temperature" as more Venus does not. When having the correct answer moderate temperature, this would allow for the water to be supplied. But, as for it not to have the correct and moderate temperature, this would then allow for it not to have to supply of water.
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
"It is important to balance chemical equations because there must be an equal number of atoms on both sides of the equation to follow the Law of the Conservation of Mass"
Answer:
2.86 kJ
Explanation:
When a substance is heated and there's no phase change happening, the amount of heat (Q) necessary for the heating can be calculated by:
Q = m*c*ΔT
Where m is the mass, c is the specific heat capacity of the substance, and ΔT is the variation of temperature. So, in this case, m = 53.8 g, c = 1.05 J/g°C, and ΔT = 50.6 K. The temperature variation is the same in °C and K, so:
Q = 53.8*1.05*50.6
Q = 2858.394 J (÷1000)
Q = 2.86 kJ
