Answer :

Example of polar covalent molecules H-O-H(water), ammonia

Explanation:

The presence of intermolecular Hydrogen bonding makes the boiling point of water unexpectedly high, and the polar covalent nature makes it dissolve polar solute/compound

Answer:

Explanation:

The constituent of a water molecule is one oxygen atom and two hydrogen atom. Oxygen is highly electronegative ( ability to pull electron closer to itself in a covalent bond) compare to hydrogen and as such it creates two poles with oxygen been partially negative and hydrogen been partially positive.  This attributes allow water to dissolve polar substances such sodium chloride, sodium hydroxide. When this substance are added to water, they are pull apart with positive sodium ion attracted to the partially positive oxygen and the chloride ions attracted to the partially positive hydrogen.

The polarity of water ice is able to float in water because of the polar nature as the molecules is extended as far as possible and are held together by the hydrogen bond. Water expands when its freezes and it  density decreases

The polar nature also of its molecules also contributes to its high boiling, freezing point and strong surface tension.

How many moles of oxygen will occupy a volume of 2.50 liters?
loris [4]
Data:
n (number of mols) = ? 
V (volume) = 2.50 Liters 
If: 
1 L → 1000 g
2.50 L → y

y = 1000*2.50 = 2500 g

Therefore:
m (mass) = 2500 g

Now:
Molar Mass (MM) of oxygen = 16 g/mol

Formula:
n =  \frac{m}{MM}

Solving:
n = \frac{m}{MM}
n = \frac{2500\:\diagup\!\!\!\!\!g}{16\:\diagup\!\!\!\!\!g/mol}
\boxed{\boxed{n = 156.25\:mols}}\end{array}}\qquad\quad\checkmark

Why is the increasing amount of carbon dioxide being taken up by the oceans a cause for concern?
Anna007 [38]

Answer;

-More carbon dioxide causes an increase in carbonic acid (H2CO3) which leads to a decrease in the concentration of carbonate ion (CO32-).

Explanation;

-Carbon dioxide is added to the atmosphere whenever people burn fossil fuels. Oceans play an important role in keeping the Earth's carbon cycle in balance.

-As the amount of carbon dioxide in the atmosphere increases, the oceans absorb a lot of it. In the ocean, carbon dioxide reacts with seawater to form carbonic acid which causes the acidity of seawater to increase.

-As long as we keep putting extra carbon dioxide in the atmosphere, the acidity of the ocean will continue to increase. The effect is that; Increasing acidity makes it harder for corals to build skeletons and for shellfish to build the shells they need for protection. Corals are particularly important because they provide homes for many other sea creatures.
