Answer: 2800 calories
Explanation:
Latent heat of fusion is the amount of heat required to convert 1 mole of solid to liquid at atmospheric pressure.
Amount of heat required to fuse 1 gram of water = 80 cal
Mass of ice given = 35 gram
Heat required to fuse 1 g of ice at = 80 cal
Thus Heat required to fuse 35 g of ice =
Thus 2800 calories of energy is required to melt 35 g ice cube
D. More collisions occur and the time required for the reaction decreases
This happens because according to collision theory, when energy (in this case, thermal energy) is applied to particles, they move/vibrate more quickly.
The correct answer is d)all of above
examples for a are tyrosine for b lysine and for c isoleucine

Answer:
Explanation:
a. CuO+ 2HCl⇒CuCl2+ H2O
b. = = 0,05 (mol)
⇒= =0,05 mol
⇒= 0,05×135=6,75 (g)
c. =2× =0,1 (mol)
⇒= 0,1×36,5= 3,65 (g)
⇒= ×100=36,5 (g)
⇒ Nồng độ phần trăm dd sau phản ứng= Nồng độ % dd CuCl2=×100= ×100≈ 16,67%
