Answer:
22.44°C will be the final temperature of the water.
Explanation:
Heat lost by tin will be equal to heat gained by the water

Mass of tin = 
Specific heat capacity of tin = 
Initial temperature of the tin = 
Final temperature =
=T

Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water =
=T



On substituting all values:

we get, T = 22.44°C
22.44°C will be the final temperature of the water.
The answer is God because if you think on it hard enough, you realize that we couldnt of come from nowhere. Then, you get a headache and just stop thinking about.
Hope this helps :D
Answer:
Half-life at 629K = 252.4min
Explanation:
Using Arrhenius equation:

And as Half-life in a first order reaction is:

We can convert the half-life of 58.0min to know K₁ adn replacing in Arrhenius equation find half-life at 629K:

K = 0.01195min⁻¹ = K₁



K₂ = 2.75x10⁻³ min⁻¹
And, replacing again in Half-life expression:

<h3>Half-life at 629K = 252.4min</h3>
