A sample of ethanol has a volume of 7.5 mL and a mass of 5.85 g. A sample of benzene also has a volume of 7.5 ml,but has a mass of 6.60 g. Which liquid is denser

Answers

Answer 1
Answer:

Answer:

Benzene is denser than ethanol.

Explanation:

Given data:

Volume of ethanol = 7.5 mL

Mass of ethanol = 5.85 g

Volume of benzene = 7.5 mL

Mass of benzene = 6.60 g

Which is denser = ?

Solution:

First of all we will calculate the density of both substances.

Density of ethanol:

d = m/v

d = 5.85 g/ 7.5 mL

d = 0.78 g/mL

Density of benzene:

d = m/v

d = 6.60 g/ 7.5 mL

d = 0.88 g/mL

The density of benzene is higher thus it is denser than ethanol.
Answer 2
Answer:

Answer:

Benzene

Explanation:

You need to calculate the densities for each compound.

EtOH = 5.85/7.5 = 0.78 g/mL

Benzene = 6.60/7.5 = 0.88 g/mL

0.88 > 0.78, thus benzene is denser than ethanol.

What is the difference between periods and groups on the periodic table?

Answers

Periods are rows horizontally along the periodic table whereas groups are vertical columns down the periodic table.
Elements in the same group react similarly. E.g. the group 1 metals (found in the first column of the periodic table) react readily with air and water (this is the similarity) but these reactions become more vigorous / explosive as you go down the group (this is why they are similar but not the same). This is because elements in the same group have the same number of electrons in their outermost energy level (and electrons are responsible for how an element reacts)
Elements in the same period of the periodic table have the same number of inner most (also known as 'main') energy levels so have the same amount of electron shielding.

If a plant needs to make 12.6 g of glucose(c6h1206), how many grams of water are required?

Answers

Answer: 7.6 g of water are required to make 12.6 g of glucose

Explanation:

Moles is calculated by using the formula:

Moles=\frac{\text{Given mass}}{\text{Molar mass}}

{\text {moles of glucose}}=(12.6g)/(180g/mol)=0.07moles

The balanced chemical equation is:

6CO_2+6H_2O\rightarrow C_6H_(12)O_6+6O_2

According to stoichiometry:

1 mole of glucose is produced by = 6 moles of water

Thus 0.07 moles of glucose is produced by =(6)/(1)* 0.07=0.42 moles of water

Mass of water required =moles* {\text {Molar mass}}=0.42mol* 18g/mol=7.6g

Thus 7.6 g of water are required to make 12.6 g of glucose

Which term identifies a type of nuclear reaction?(A) fermentation
(B) reduction
(C) deposition
(D) fission

Answers

of the above options you've given, the only nuclear reaction is fission.

fermentation is when organic matericals go bad and delope mold for exg,

reduction is when atoms of elements have their oxidation states changed (exg rusting)

deposition is when molecules set out in any sort of solution.

Answer: Option D) is correct which is fission
