Answer:
3 salad = 3 lettuce + 6 tomatoes + 9 three carrots
Coefficients: 3, 6, 9
Explanation:
1 salad = 1 lettuce + 2 tomatoes + 3 three carrots
<em>Multiply all the coefficients of 1 salad by 3:</em>
3(1 salad) = 3(1 lettuce + 2 tomatoes + 3 three carrots)
<em>Expand the equation:</em>
3 salad = 3 lettuce + 6 tomatoes + 9 three carrots
If I remember correctly, you would have to heat the reaction beaker over a burner..
I apologize if I'm wrong
pH solution = 8.89
<h3>Further explanation</h3>
Given
The concentration of HBr solution = 1.3 x 10⁻⁹ M
Required
the pH
Solution
HBr = strong acid
General formula for strong acid :
[H⁺]= a . M
a = amount of H⁺
M = molarity of solution
HBr⇒H⁺ + Br⁻⇒ amount of H⁺ = 1 so a=1
Input the value :
[H⁺] = 1 x 1.3 x 10⁻⁹
[H⁺] = 1.3 x 10⁻⁹
pH = - log [H⁺]
pH = 9 - log 1.3
pH = 8.89
The chemical change would occur faster in Beaker X due to the fact that the contents are warmer.
Answer: 1mole
Explanation:
Mole = concentration× Volume (dm3)
Mole = 2× 500/1000
