B because binary compound is a compound of two chemicals
An acid is a hydrogen containing substance with a PH between 1-7 and is capable of donating a proton (hydrogen ion)
Given parameters:
Heat of fusion of water = 334j/g
Mass of ice = 45g
Temperature of ice = 0.0°c
Unknown:
Amount of heat needed to melt = ?
Solution:
This is simply a phase change and a latent heat is required in this process.
To solve this problem; use the mathematical expression below;
H = mL
where m is the mass
L is the heat of fusion of water;
H = 45 x 334 = 15030J
D= mass over volume
So, density equals 9.0g divided by 45ml.
SO, D=.25 g/ml
I'm not 100% sure this is correct, though. Best if luck. ♡
Answer:
Good examples are the reshaping of a coastline by a tsunami, deposition of mud by a flooding river, the devastation brought by a volcanic explosion, or a mass extinction caused by an asteroid impact.
