K2S (aq) + CoCl2( aq) ----->   2KCl (aq) + CoS (s)
potassium   +  cobalt                potassium chloride  + carbonyl  sulfide 
sulfide          chloride 

carbonyl sulfide :-  it is chemical compound with linear formula (OCS ) normally written as (CoS)  .it does not show its structure . its is colorless flammable gas with an unpleasant odour.
Potassium chloride :-  It is metal halide salt composed of potassium and chlorine. it is odorless and has white or colorless crystal appearance <span />

when 45 grams of copper (ii) carbonate are decomposed with heat how many grams of carbon dioxide will be produced
Maksim231197 [3]

Answer:

16.02 g

Explanation:

the balanced equation for the decomposition of CuCO₃ is as follows

CuCO₃ --> CuO + CO₂

molar ratio of CuCO₃ to CO₂ is 1:1

number of CuCO₃ moles decomposed - 45 g / 123.5 g/mol = 0.364 mol

according to the molar ratio

1 mol of CuCO₃ decomposes to form 1 mol of CO₂

therefore 0.364 mol of  CuCO₃ decomposes to form 0.364 mol of CO₂

number of CO₂ moles produced - 0.364 mol

therefore mass of CO₂ produced - 0.364 mol x 44 g/mol = 16.02 g

16.02 g of CO₂ produced

Corrections here: 1. When calcium reacts with water, the temperature changes from 18c to 39c
Ugo [173]

When calcium reacts with water, the temperature changes from 18c to 39c is an exothermic reaction as energy is releasing and increasing the temperature.

<h3>What is an exothermic reaction?</h3>

Exothermic reaction are those reactions in which energy is released when a reaction completes.

An example is burning of wood.

Thus, when calcium reacts with water, the temperature changes from 18c to 39c is an exothermic reaction as energy is releasing and increasing the temperature.
