Since the new oceanic crust is created at the mid-ocean ridges, then the Earth is getting bigger.

Chemistry
1 answer:
Svet_ta [14]3 years ago
7 0

Answer:

False

Explanation:

It is true that new crust is being created at the mid-oceanic ridges, but this does not make the Earth any bigger despite the the growth of oceanic crusts in these regions.

The reason that Earth does not get bigger is because the same plates that are being created at the divergent plate boundaries are recycled into the mantle at the subduction zones. Because of this, the surface area of the Earth remains the same.

Water contrasts on freezing ?
Airida [17]

No. When water first begins to cool down, it contracts. However, as it gets colder and eventually freezes, it begins to expand.

You can test this by freezing water in a water bottle: when you take it out of the freezer, the cap might have popped off or cracks may have formed in the sides of the bottle.

Answer: Water expands when frozen, not contracts.

Fatty acids are ________ Group of answer choices composed of carbon, hydrogen, and oxygen in a 1:2:1 ratio. composed of carbon,
VLD [36.1K]

Fatty acids are composed of hydrocarbon chains and a carboxyl group.

<h3>What are Fatty acids ?</h3>

Fatty acids are the building blocks of the fat in our bodies and in the food we eat.

During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood.

Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride.

Generally, a fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end.

It is that carboxyl group that makes it an acid (carboxylic acid).

2 moles of sodium phosphate reacts with 3 moles of
miss Akunina [59]

Answer: 6 moles of NaCl are produced when 2 moles of sodium phosphate reacts with 3 moles of  calcium chloride

Explanation:

The balanced chemical equation is:

2Na_3PO_4+3CaCl_2\rightarrow 6NaCl+Ca_3(PO_4)_2  

According to stoichiometry :

2 moles of Na_3PO_4 require 3 moles of CaCl_2

Thus both are limiting reagent as both will limit the formation of product.

As 2 moles of Na_3PO_4 reacts with 3 moles of CaCl_2 give = 6 moles of NaCl

Thus 6 moles of NaCl are produced when 2 moles of sodium phosphate reacts with 3 moles of  calcium chloride
