<span>Answer:
Bronsted base is something that accepts proton (H+) and acid is something that donates H+
so here CH3NH2 will be the base and H2S is the acid.</span>
Answer:
4.67 kg
Explanation:
Given data
- Dimensions of the lead sheet: 75.0 cm by 55.0 cm by 0.10 cm
- Density of lead: 11.3 g/cm³
Step 1: Calculate the volume of the sheet
The volume of the sheet is equal to the product of its dimensions.

Step 2: Calculate the mass of the sheet
The density (ρ) is equal to the mass divided by the volume.

Answer:
C₂ = 0.149 M
Explanation:
Given data:
Initial concentration = 0.407 M
Initial volume = 2.56 L
Final volume = 7.005 L
Final concentration = ?
Solution:
Formula:
C₁V₁ = C₂V₂
C₁ = Initial concentration
V₁ = Initial volume
C₂ = Final concentration
V₂ =Final volume
Now we will put the values.
0.407 M × 2.56 L = C₂ × 7.005 L
1.042 = C₂ × 7.005 L
C₂ = 1.042 M.L / 7.005 L
C₂ = 0.149 M
Answer:
The equilibrium position will shift towards the lefthand side.
Explanation:
[CoCl4] 2- (aq) + 6H2O (l) ⇌ [Co(H2O)6] 2+ (aq) + 4 Cl- (aq)
The equation written above in exothermic as written. That is, the forward reaction is exothermic. The equilibrium position is observable by monitoring the colour change of the solution. At the left hand side, the solution is blue but at the right hand side the solution is pink. Addition of heat (in a hot water bath) will shift the equilibrium towards the left hand side, that is formation of more [CoCl4] 2- making the solution to appear blue in colour.
