<span>The answer is amino acids. This one is organic compounds containing amine and carboxyl functional group and with a side chain. The elements of this amino are carbon, hydrogen, oxygen and nitrogen and the elements found in the side chains of certain amino acids. It consists of carboxylic acid group and amine. This is called 2-alpha.</span>
Answer:
24.1kJ
Explanation:
Heat capacity of water = 4200
Latent Heat of ice = 333550
Heat of Fusion = m × l = 333550 × (32/1000)kg = 10,672 = 10.672kJ
H = (m × c × change in temperature)
H = (32/1000)kg × 4200 × (85 -- 15)
H = (32/1000) × 4200 × 100
H = 13,440J = 13.44kJ
So amount of heat = 13.44kJ + 10.672kJ = 24.112kJ ~ 24.1kJ
Answer:
From the given variable values, we can calculate the density of the rock sample to be = 10750_Kg/m^3
Explanation:
To solve this question, we recollect that density is the mass per unit volume of a substance and the SI unit of density is Kg/m^3 with symbol
ρ
The given variables are as follows
mass of rock sample = 8.6g
The volume displaced in the graduated cylinder is
(Final volume level of the cylinder) - (initial volume level of the cylinder)
13.6ml - 12.8 ml= 0.8ml = volume of the rock sample
Therefore, density = 8.6/0.8 = 10.75g/ml = or 1000×10.75 Kg/m^3 =10750Kg/m^3
Density of the rock sample is 10750Kg/m^3
