Martije has made a slight error in naming a compound monocarbon tetrabromide. What compound is she most likely naming, and what
Burka [1]
The slight error has been to use the prefix mono to name monocarbon.

The compound she is most likely naming is:

 CBr_4.

As you see, the chemical formula has 1 atom of C, which is likely why she named it mono, and 4 atoms of Br.

The right name is carbon monobromide, i.e. you have to supress the prefix mono, as per IUPAC rules.

How many moles are in 128.9 grams of Cr2(SO3)2?
Dominik [7]

Answer: 0.5 moles

Explanation:

Cr2(SO3)2 is the chemical formula for chromium sulphate.

Given that,

Amount of moles of Cr2(SO3)2 (n) = ?

Mass of Cr2(SO3)2 in grams = 128.9g

For molar mass of Cr2(SO3)2, use the atomic masses:

Chromium, Cr = 52g;

Sulphur, S = 32g;

Oxygen, O = 16g

Cr2(SO3)2 =

(52g x 2) + [(32g + 16g x 3) x 2]

= 104g + [(32g + 48g) x 2]

= 104g + [80g x 2]

= 104g + 160g

= 264g/mol

Since, n = mass in grams / molar mass

n = 128.9g / 264g/mol

n = 0.488 mole [Round the value of n to the nearest tenth which is 0.5

Thus, there are 0.5 moles in 128.9 grams of Cr2(SO3)2

What can you do to make the chicken egg float in the water?Explain your answer.(Science)​
Goryan [66]

Denser salt water makes the eggs to float in the water.

<u>Explanation: </u>

Egg will always sink in water, as egg is denser than water.

But we can make it to float by means of adding excess salt to the water. Adding more salt to water makes it as denser than egg. Denser water makes less dense egg to float in water.

So, making the water as denser one leads to the floating of egg in the water.
