Answer:
prepared by mixing 20 ml of 0050 m hcl with 30 ml of 010 m ba oh 2 ... No. of milliequivalents of HCl = 2× 0.05 × 1. =1.
Explanation:
is this ?
C4H6O3 + H2O → 2 С2Н402
Explanation:
To balance the equation
C4H6O3 + H2O → С2Н402
On the reactant side
C = 4
H = 8
O = 4
On the product side
C = 2
H = 4
O = 2
So by putting 2 on the product side to С2Н402, we can balance the equation on both the sides.
Hence, the balanced equation is
Acetic Anhydride + Water → 2 molecules of Acetic Acid
C4H6O3 + H2O → 2 С2Н402
a gas exert a pressure of 6.20 atm in a container with a volume of 475.2 ml will exert a pressure of 9.150 atm when transferred to a container with a volume of 322 ml
Explanation
This is calculated using the Boyles law formula
that is P1V1= P2V2
P1=6.20 atm
V1=?
P2=9.150 atm
V2= 322 ml
by making V1 the subject of the formula
V1= P2V2/P1
V2 is therefore = (9.150 atm x322 ml) / (6.20 atm-) = 475.2 ml
Answer:
b) 7
Explanation:
The pH of a solution produced by the neutralization reaction between 1M of H₂SO₄ and KOH with 1M is closest to 7.
pH is a standard for measuring the acidity and alkalinity of a solution. A solution that is acidic will have a pH less than 7, a neutral solution will have pH of 7 and a basic solution will have pH greater than 7.
What is a neutralization reaction?
- It is an acid-base reaction in which hydrogen and hydroxide ions combines to form water.
- Also a salt results from the combination of the other ions.
In this reaction a base simply neutralizes an acid and the solution becomes neutral before it goes into completion.
Therefore, a neutral solution will have pH of 7 or close to it.
C. Dissolution is associated with heat change.
