Solubility of khp in water is greater than many fatty acids because khp is a polar substance while fatty acids are non-polar. Khp has positive and negative charges which help it to dissociate into ions when it dissolves in water. Fatty acids on the other hand contain long unbranched hydrocarbons with one end having a carboxylic acid group. This make water molecules to repel from them because no part of the fatty acid molecules have any charge.
Answer: The final energy is 1,700 J
Explanation: According to first law of thermodynamics:
=Final energy-initial energy=Change in internal energy
q = heat absorbed or released
w = work done by or on the system
w = work done by the system=
{Work done by the system is negative as the final volume is greater than initial volume}
q = +500J {Heat absorbed by the system is positive}
w = work done by the system = -300J
You need 158.70 grams of Fe2O3 to produce 111 grams of Fe. This is calculated by using the molar masses and stoichiometric relationship of the two compounds.
Solution:
MM Fe = 55.845 g/mol
MM Fe2O3 = 159.69 g/mol
Fe: Fe2O3 = 2 mol:1 mol
11 g FE (1 mol Fe/55.845 g Fe) (1 mol Fe2O3/2 mol Fe) (159.69 g Fe2O3 / 1 mole Fe2O3) = 158.70 grams Fe2O3
Answer:
I cant see the picture but
heeeerrrrreeeee
The balanced chemical equations are as follows:
- AlBr₃ + K → 3 KBr + Al
- FeO + PdF₂ → FeF₂ + PdO
- P₄ + 6 Br₂ → 4 PBr₃
- 2 LiCl + Br₂ → 2 LiBr + Cl₂
<h3>What are balanced chemical equations?</h3>
Balanced chemical equations in which the moles of atoms of elements taking part in a reaction are balanced on both sides of the equation.
The balancing of chemical equations follows the law of conservation of mass which states that matter can neither be created nor destroyed.
In balancing of chemical equations, the following steps are follows:
- ensure that the all the substances involved are written in the equation
- do not alter the formula of compounds or molecules
- add numerical coefficients in front of the compounds and molecules to ensure that the moles of atoms of elements are balanced on both sides of the equation
In conclusion, a balanced chemical equation obeys the law of conservation of mass.
