Red blood cell is the answer I think
Answer:
H2O2
Explanation:
2 hydrogen, 2 oxygen wikipedia it
Answer:
0.3M
Explanation:
Step 1:
Data obtained from the question. This include the followingb:
Volume of acid (Va) = 90mL
Concentration of acid (Ca) = 0.2M
Volume of base (Vb) = 60mL
Concentration of base (Cb) =....?
Step 2:
The balanced equation for the reaction. This is given below:
HBr + NaOH —> NaBr + H2O
From the balanced equation above,
The mole ratio of the acid (nA) = 1
The mole ratio of the base (nB) = 1
Step 3:
Determination of the concentration of the base, NaOH.
The concentration of the base can be obtained as follow:
CaVa /CbVb = nA/nB
0.2 x 90 / Cb x 60 = 1
Cross multiply
Cb x 60 = 0.2 x 90
Divide both side by 60
Cb = 0.2 x 90 /60
Cb = 0.3M
Therefore, the concentration of the base, NaOH is 0.3M
The main reason behind this is Boyle's law and Gay Lussacs law
- Gay Lussac's law states that Pressure is directly proportional to Temperature.
- Boyle's law states that Volume is inversely proportional to pressure.
If temperature will be more Pressure will be more
The weak acid will have fewer ions than the strong acid of similar concentration.
The chemical reactions for a weak acid and a strong acid is given below:
- Strong acid: HA → H⁺ + A⁻
- Weak acid: HA ⇆ H⁺ + A⁻
<h3>What are strong and weak acids?</h3>
Strong acids are acids which dissociate completely in solutions. Examples of strong acids are hydrochloric acid and sulfuric acid.
Weak acids are acids which dissociate only partially in solutions. Examples of weak acids are carbonic acid and acetic acid.
Weak acids of a similar concentration to a strong acid have fewer hydrogen ions.
The equation of the dissociation of strong acids and weak acids are given below:
- Strong acid: HA → H⁺ + A⁻
- Weak acid: HA ⇆ H⁺ + A⁻
In conclusion, weak acids produce few ions in solution while strong acids fully dissociate into ions in solution.
