The concentration of the solution decreases hence the time taken for the cross to become invisible increases.
<h3>Rate of reaction</h3>
The term rate of reaction refers to how quickly or slowly a reaction occurs. This is usually measured in units of time. We are now going to look at the scenario in the question.
We know that rate of reaction depends on the concentration of the reactants. The higher the concentration, the more the reacting particles in solution and the faster the rate of reaction.
As the volume of thiosulphate decreases and the volume of water increases, the concentration of the solution decreases hence the time taken for the cross to become invisible increases.

Answer:
The temperature would be reduced by half
Explanation:
Charles' Law => V ∝ T => V = kT => k = V/T
For two sets of T vs V conditions, the system constant (k) remains unchanged and k₁ = k₂ => V₁/T₁ = V₂/T₂.
Therefore, if V₁ is reduced to 1/2V₁ = V₂ => V₁/T₁ = 1/2V₁/T₂ => V₁/T₁ = V₁/2T₂
and solving for T₂ => 1/T₁ = 1/2T₂ => 2T₂ = T₁ => T₂ = 1/2T₁
∴ The initial temperature (T₁) would be reduced by half or, T₂ = 1/2T₁
Flat as more oxygen and water can react over it think of it like this would a cube rust faster than a sheet
Molar mass <span>Aluminium ( Al) = 26.98 g/mol
1 mole ------------ 26.98 g
? mole ----------- 2.98 g
moles Al = 2.98 x 1 / 26.98
moles Al = 2.98 / 26.98
= 0.110 moles
hope this helps!

Answer:
104,000 has 3 significant figure.
Explanation:
This is because all non-zero digits are significant and zeros in between non-zero digits are significant.
