Answer: briitle would be easy to dislove
Explanation:
Explanation:
It is known that density is the amount of mass present in liter of solution or substance.
Mathematically, Density =
It is given that volume is 3.25 L and mass is . Hence, calculate the density of glycerol as follows.
Density =
=
=
As, 1 L = 1000 .
So,
=
Thus, we can conclude that the density of glycerol is .
The second answer would be correct.
When fossil fuels combust, compounds such as NOₓ (Nitrogen Oxides) and SO₂ (Sulfur Dioxide). These compounds can then react with the environment to form the acids sulfuric acid and nitric acid, which, when reacted with water, release H₊ ions. The higher the concentration of H₊ ions, the more acidic the solution.

Answer:
53·32 g
Explanation:
<h3>Given the ΔH for the reaction is for 1 mole of benzene(C6H6) and 1 mole of benzene contains 78 g of benzene</h3>
So for 78 g of benzene ΔH of the reaction is 630 kJ
Let the weight of benzene that must decompose to transfer 430 kJ of heat be m g
∴ 78 ≡ 630
m ≡ 430
For 1 kJ of heat to be transferred the weight of benzene required is 78 ÷ 630 = 0·124 g
For 430 kJ of heat to be transferred the weight of benzene required is 0·124 × 430 = 53·32 g
∴ m = 53·32 g
∴ 53·32 grams of C6H6 must decompose according to the given chemical equation to transfer 430 kJ of heat
