The paper clips will magnetically connect to the nail. With the copper wire wrapped around then nail, it makes a magnetic field that, when powered will cause metal objects to come toward it, hence why it is called an "electromagnet".

Hope this helps!!!

Answer:

Solution given:

c) Magnesium metal plus silver acetate (teachers note:

Balanced chemical equation:

$\boxed{\bold{\green{Mg+AgC_{2}H_{3}O_{2}\rightarrow MgC_{3}H_{3}O_{2}+Ag^{+}}}}$

d) hydrobromic acid plus zinc metal (teachers note:

Balanced chemical equation:

$\boxed{\bold{\green{2HBr+Zn \rightarrow Be_{2}+H_{2}}}}$

In Ontario, some electricity comes from coal-burning generators. Coal is a natural form of carbon that has a large amount of sul

irinina [24]

Answer:

$C(s)+O_{2}(g) \rightarrow CO_{2}(g)$

$S(s)+O_{2}(g) \rightarrow SO_{2}(g)$

Sulphurdioxide

$SO_{2}(g) + H_{2}O(l) \rightarrow H_{2}SO_{3}(l)$

$SO_{2}(g) + \frac{1}{2}O_{2} \rightarrow SO_{3}(g)$

Incomplete combustion produce harmful gases.

Explanation:

Carbon reacts with atmospheric oxygen to form carbondioxide as well as sulphur dioxide.

The chemical equations are as follows.

$C(s)+O_{2}(g) \rightarrow CO_{2}(g)$

$S(s)+O_{2}(g) \rightarrow SO_{2}(g)$

Sulfur dioxide is very harmful to the environment to cause acid rains.

This harmful gas mix with rain water to form sulphuric acid.

The balanced chemical equation for the reaction that produces harmful environmental effects is as follows.

$SO_{2}(g) + H_{2}O(l) \rightarrow H_{2}SO_{3}(l)$

$SO_{2}(g) + \frac{1}{2}O_{2} \rightarrow SO_{3}(g)$

$SO_{3}(g) +H_{2}O(l) \rightarrow H_{2}SO_{4}(l)$

In the absence of proper amount of oxygen required for combustion, incomplete combustion will take place which will result in formation of more carbondioxide an other harmful gases.
