We need to crack molecules in
order for us to get the desired molecule. For example, in the extraction of
crude oil, after entering the fractional distillation, it will give products
base on their molecular structure. The products are gasoline, diesel fuel, jet
fuel, wax, asbestos,kerosene.
M₁ = mass of water = 75 g
T₁ = initial temperature of water = 23.1 °C
c₁ = specific heat of water = 4.186 J/g°C
m₂ = mass of limestone = 62.6 g
T₂ = initial temperature of limestone = ?
c₂ = specific heat of limestone = 0.921 J/g°C
T = equilibrium temperature = 51.9 °C
using conservation of heat
Heat lost by limestone = heat gained by water
m₂c₂(T₂ - T) = m₁c₁(T - T₁)
inserting the values
(62.6) (0.921) (T₂ - 51.9) = (75) (4.186) (51.9 - 23.1)
T₂ = 208.73 °C
in three significant figures
T₂ = 209 °C
In order to find the density of an object, you need to know the mass of the object and the volume.
That is why the unit of density is kg/m3.

Higher concentrations of reactants = More collisions between molecules = More possible reactions between the molecules = Higher reaction rate
<h3>What is concentration?</h3>
A solution is made up of two components, solute and solvent. In chemistry, we define the concentration of solution as the amount of solute dissolved in the solution.
Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. This is especially true when concentrations are low and few molecules or ions are reacting.
Hence, Higher concentrations of reactants = More collisions between molecules = More possible reactions between the molecules = Higher reaction rate.
