Answer:
It gains kinetic energy
Explanation:
When something is heated, it’s molecules move faster, like a liquid’s molecules. Since the molecules vibrate faster when it’s heated and kinetic energy is which a body possesses by virtue of being in motion. Therefore, the answer is it gains kinetic energy
Answer:
What is the mass of solute, in grams, in 250.00 mL of a 0.0125 M solution of KMnO4? Moles KMnO4 = M × V = 0.0125 M × 0.250 L = 3.13 × 10-3 mol KMnO4 grams KMnO4 = 3.13 × 10-3 mol KMnO4 × ( 158.03 g KMnO4/1 mol KMnO4) = 0.495 g 4.
The answers would be the mass before a reaction is the same as the mass after a reaction which basically means mass is conserved
Answer:
4054 kcal of heat is released during complete combustion of 354 g of octane.
Explanation:
Heat of combustion of 1 mol of octane is 
kcal
Molar mass of octane = 114.23 g/mol
We know, no. of moles = (mass)/(molar mass)
So, kcal of heat is released during complete combustion of 114.23 g of octane.
So, amount of heat is released during complete combustion of 354 g of octane = 
kcal = 4054 kcal
Hence 4054 kcal of heat is released during complete combustion of 354 g of octane.
Answer:
Data is a raw and unorganized fact that required to be processed to make it meaningful. ... Generally, data comprises facts, observations, perceptions numbers, characters, symbols, images, etc. Data is always interpreted, by a human or machine, to derive meaning. So, the data is meaningless.
