Answer:

Zn + CuSO4 —> ZnSO4 + Cu

Explanation:

Zn is higher than Cu in electrochemical series and so will displaces Cu in solution according to the equation:

Zn + CuSO4 —> ZnSO4 + Cu

The density of gas particles in a section of Earth’s atmosphere decreases. Which of the following is the most likely explanation

Bad White [126]

<span>This is due to the fact that the air pressure in that certain section of Earth’s atmosphere decreased. As density of gas particles decreases as air pressure decreases. Therefore, density of gas particles and air pressure have a direct relationship. An increase in air pressure would then effect to an increase in gas particles. </span>

The compound $C_{3}H_{4}$ will have a triple bond.

Explanation:

A compound which consists of carbon and hydrogen atoms is known as a hydrocarbon.

Alkanes, alkenes and alkynes are all hydrocarbons.

General chemical formula of an alkane is $C_{n}H_{2n+2}$ . In an alkane molecule, all the atoms will be bonded through single bonds.

For example, $C_{3}H_{8}$ is propane.

General chemical formula of an alkene is $C_{n}H_{2n}$ . An alkene molecule will have atleast one double bond between two carbon atoms.

For example, $C_{2}H_{4}$ is ethene.

General chemical formula of an alkyne is $C_{n}H_{2n-2}$ . An alkyne will have atleast one triple bond between two carbon atoms.

For example, $C_{3}H_{4}$ is propyne.

Thus, we can conclude that out of the given options $C_{3}H_{4}$ will have a triple bond.

a sample of an oxide of antimony (sb) contain 19.75 g of antimony combine with 6.5 g of oxygen . what is the simplest formula fo

frez [133]

Explanation:

The given data is as follows.

Mass of antimony = 19.75 g

Molar mass of Sb = 121.76 g/mol

Therefore, calculate number of moles of Sb as follows.

Moles of Sb = $\frac{mass}{\text{molar mass}}$

= $\frac{19.75 g}{121.76 g/mol}$

= 0.162 mol

Mass of oxygen given is 6.5 g and molar mass of oxygen is 16 g/mol. Hence, moles of oxygen will be calculated as follows.

Moles of oxygen = $\frac{mass}{\text{molar mass}}$

= $\frac{6.5 g}{16 g/mol}$

= 0.406 mol

Hence, ratio of moles of Sb and O will be as follows

Sb : O

$\frac{0.162}{0.162} : \frac{0.406}{0.162}$

1 : 2.5

We multiply both the ratio by 2 in order to get a whole number. Therefore, the ratio will be 2 : 5.

Thus, we can conclude that the empirical formula of the given oxide is $Sb_{2}O_{5}$ .
