Potassium chlorate is a mean little chemical. It likes to decompose rather violently, and when it does, it decomposes into two d
WARRIOR [948]

Answer:

Oxygen gas

Explanation:

Potassium chlorate KClO3 decomposes thermally to form potassium chloride KCl and oxygen gas is given off. This is in the presence of a catalyst, manganese iv oxide.

Hence, what is being said in essence is that when potassium chloride is heated in the presence of manganese iv oxide catalyst, oxygen is given off as the gaseous product with the formation of potassium chloride.

The chemical equation for the reaction is :

2KClO3 ——-> 2KCl + 3O2

This procedure is one of most important ways through which oxygen can be produced in the laboratory and can be used as a source of oxygen is industrial processes if on a large scale

What is the final temperature when 150.0 g of water at 90.0 °c is added to 100.0 g of water at 30.0 OC? Note that C, of water ca
levacccp [35]

Answer : The final temperature is, 337.8K

Explanation :

Q_{absorbed}=Q_{released}

As we know that,  

Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})

m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]         .................(1)

where,

q = heat absorbed or released

m_1 = mass of water at 90^oC = 150 g

m_2 = mass of water at 30^oC= 100 g

T_{final} = final temperature = ?

T_1 = temperature of lead = 90^oC=273+90=363K

T_2 = temperature of water = 30^oC=273+30=303K

c_1\text{ and }c_2 = same (for water)

Now put all the given values in equation (1), we get

150\times (T_{final}-363)=-[100\times (T_{final}-303)]

T_{final}=337.8K

Therefore, the final temperature is, 337.8K
