Answer:
The units of both types of energy are Joule (kg × m² × s⁻²).
Explanation:
Step 1: Show the units of kinetic energy
The equation for kinetic energy is:
K = 1/2 × m × v²
where,
m: mass
v: speed
The units are:
K = 1/2 × m × v²
[K] = kg × (m/s)²
[K] = kg × m² × s⁻² = J
Step 2: Show the units of gravitational potential energy
The equation for gravitational potential energy is:
G = m × g × h
where,
m: mass
g: gravity
h: height
The units are:
G = m × g × h
[G] = kg × m/s² × m
[G] = kg × m² × s⁻² = J
C.
Anthracite has the highest carbon compact and fewest impurities.
Also, the highest calorific of all types of coal except for graphite.
Bile salt from the gall bladder mix with fats to further break them down in a process called emulsification
Explanation
Emulsification involve breakdown of large fat globules into tiny droplet in the duodenum. This provide a large surface area on which the enzyme pancreatic lipase can act to digest the fats into fatty and qlycerol. Emulsification is assisted by action of bile salt where the secreted bile in the liver and stored in the gallbladder is released to the duodenum .
Answer:
The molar mass of H₂O₂ (the solute) in the aqueous solution of
H₂O₂ is 51 g
Explanation:
Given;
H₂O₂ compound
Concentration of aqueous solution of H₂O₂ = 1.5M
The molecular mass of H₂O₂ = (1 x 2) + (16 x 2) = 34 g/mol
Reacting mass (g) = Concentration x Molar mass
Reacting mass (g) = 1.5 x 34
Reacting mass (g) = 51 g
Therefore, the molar mass of H₂O₂ (the solute) in the aqueous solution of
H₂O₂ is 51 g
