Explanation:

12)

a) Sodium + oxygen = ?

When sodium reacts oxygen its forms sodium oxide as a product.

$4Na(s)+O_2(g)\rightarrow 2Na_2O(s)$

b) magnesium + fluorine = ?

When magnesium reacts with fluorine its forms magnesium fluoride as a product.

$Mg(s)+F_2(g)\rightarrow MgF_2(s)$

13)

a) $2HgO(s)\overset{\Delta }\rightarrow 2Hg(l)+O_2(g)$

Decomposition of mercury(II) oxide on heating gives out mercury and oxygen gas.

b) $2H_2O(l)\overset{Electricity}\rightarrow 2H_2(g)+O_2(g)$

The electrolytic decomposition of water gives out hydrogen gas amd oxygen gas.

Adding more than one equivalent of HCl to pent-1-yne will lead to which product:______.

Ket [755]

Answer:

c. 2,2-dichloropentane.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to firstly draw the structure of the reactant, pent-1-yne:

$CH\equiv C-CH_2-CH_2-CH_2$

Now, we infer the halogen is added to the carbon atom with the most carbon atoms next to it, in this case, carbon #2, in order to write the following product:

$CH\equiv C-CH_2-CH_2-CH_2+2HCl\rightarrow CH_3- CCl_2-CH_2-CH_2-CH_2$
