Answer:

decomposition reaction

Explanation:

The reaction equation is given as:

_Ca(OH)₂ → _CaO + _H₂O

This reaction is a decomposition reaction in which a single reactant breaks down to give two or more products.

To balance the equation, we assign variables a, b and c, then we use a mathematical approach to solve the problem;

aCa(OH)₂ → bCaO + cH₂O

Conserving Ca : a = b

O: 2a = b + c

H: 2a = 2c

let a = 1, b = 1 , c = 1

NISA [10]

Answer:

6.15.3 k

Explanation:

From the question we can see that

q = 0, Δu = w

Then,

$T_f = \frac{C_{V,m}+RP_{ext}P_i}{C_{V,m}+RP_{ext}P_f} T_i$

putting values wet

= $\frac{2.5\times 8.314+8.314\left(10^5\right)\left(3.20\times 10^5\right)}{2.5\times 8.314+\left(8.314\right)\left(10^5\right)\left(10^5\right)}\times \:293$

T_f = 615.3 K
