Answer:

The answer to your question is:

Explanation:

Reaction

              Na₂SO₄ (aq)    +    CaCl₂(aq)     ⇒      CaSO₄(s)      +     NaCl(aq)

                                       2 -------------  Na ---------------  1

                                        1 ------------    S   --------------    1

                                        1  ----------    Ca --------------     1

                                        2 ------------   Cl --------------     1

                                        1 ------------    O --------------     1

Then, there are less Na and Cl in the products, so,

              Na₂SO₄ (aq)    +    CaCl₂(aq)     ⇒      CaSO₄(s)      +    2 NaCl(aq)

                                        2 -------------  Na ---------------  2

                                        1 ------------    S   --------------    1

                                        1  ----------    Ca --------------     1

                                        2 ------------   Cl --------------     2

                                        1 ------------    O --------------     1

Now, the reaction is balanced.

Hydrocarbons, compounds containing only carbon and hydrogen, are important in fuels.The heat of combustion of cyclopentane, C5H1
shtirl [24]

Answer : The balanced equation for the complete combustion of cyclopentane will be :

2C_5H_{10}+15O_2\rightarrow 10CO_2+10H_2O

Explanation :

As we know that the hydrocarbons can undergo complete or incomplete combustion that depends on the amount of oxygen available.

Complete combustion : It takes place when there is a good supply of oxygen. In this, hydrocarbon react with the oxygen to give carbon dioxide and water as a product.

The general reaction will be :

\text{Hydrocarbon}+O_2\rightarrow CO_2+H_2O

Incomplete combustion : It takes place when there is a poor supply of oxygen. In this, hydrocarbon react with the oxygen to give carbon monoxide, carbon dioxide and water as a product.

The general reaction will be :

\text{Hydrocarbon}+O_2\text{(limited)}\rightarrow CO+CO_2+H_2O

As per question, the complete combustion of cyclopentane react with oxygen to gives carbon dioxide and water as a product.

Therefore, the balanced chemical reaction will be :

2C_5H_{10}+15O_2\rightarrow 10CO_2+10H_2O

If you want to melt ice into liquid water, does the ice absorbs heat or release heat? Is this endothermic or exothermic?
kherson [118]

Answer:

Endothermic

Explanation:

This would be an endothermic reaction, due to the fact that the water would be signifigantly warmer then the ice cube, which causes it to melt.
