Answer:
T₂ = 43.46 °C
Explanation:
Given that:
The heat of the formation of carbon dioxide = - 393.5 kJ/mol (Negative sign suggests heat loss)
It means that energy released when 1 mole of carbon undergoes combustion = 393.5 kJ = 393500 J
Heat gain by water = Heat lost by the reaction
Thus,
For water:
Mass of water = 5100 g
Specific heat of water = 4.18 J/g°C
T₁ = 25 °C
T₂ = ?
Q = 393500 J
So,
T₂ = 43.46 °C
Your answer is <span>D) The angle of light from the sun as it reflects off the moon and viewed from the Earth's surface because of the way the sun hits the moon one side has to light the other doesn't and when the moon rotates the sun hits another part of the moon.

Answer:
true
Explanation:
osmosis is a special case of diffusion. diffusion occurs across a semipermeable membrane and only the water or other solvent moves. Diffusion and osmosis are both passive transport processes that act to equalize the concentration of a solution.
Usad fact copper and sulfur and silicon insulator
We classify them as follows:
1. 1 mol NaCl (s) à 1 mol NaCl(l)
C Molar heat of fusion; endothermic
2. C4H10 O(l) à C4H10O (g)
B Molar heat of vaporization; endothermic
3. H2O(g) à H2O (l)
D Molar heat of condensation; exothermic
4. 1 mol NaCl(s) + 3.88 kJ/molà 1 mol NaCl(aq)
A Molar heat of solution; endothermic
