1 answer:

4 0

I think the correct answer from the choices listed above is option B. Salting is used as one of the methods of preserving fish because s<span>alting of fish leads to diffusion of water out of the fish, causing removal of water, making the fish drier which does not allow bacteria to grow.</span>

A bottle of coke is 250.0 mL. What is the volume in cubic centimeters?

hoa [83]

Answer:

The volume in cubic centimeters is 250

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

So:

$x=\frac{c*b}{a}$

The direct rule of three is the rule applied in this case where there is a change of units. To perform this conversion of units, you must first know that 1 mL = 1 cubic centimeters. So, if 1 cubic centimeters is 1 mL, how many cubic centimeters equals 250 mL?

$cubic centimeters=\frac{250 mL*1 cubic centimeters }{1 mL}$

cubic centimeters= 250

<u><em>The volume in cubic centimeters is 250</em></u>

Which sample contains the largest number of oxygen atoms? Select one: a. 8.0 g of carbon dioxide b. 8.0 g of potassium chlorate

adell [148]

The sample with the largest number of oxygen atoms will be calcium perchlorate.

<h3>Number of atoms in a compound</h3>

Since we are not looking at the number of moles, the mass of the compounds has no bearing on the number of atoms of oxygen.

The chemical formula for carbon dioxide is $CO_2$ . Thus, it has 2 atoms of oxygen.
The chemical formula for potassium chlorate is $KClO_3$ . Thus, it has 3 oxygen atoms.
The chemical formula for calcium perchlorate is $Ca(ClO_4)_2$ . Thus, it has 8 atoms of oxygen.
The chemical formula for sodium hydroxide is NaOH. Thus, it has 1 atom of oxygen.
