Answer:

Tin + silver trioxonitrate V -------->Tin IV nitrate + silver

Explanation:

The term word equation refers to an equation in which the reactants and products are written in words rather than chemical symbols.

Note than tin is above silver in the electrochemical series hence silver will be displaced by tin as follows;

Tin + silver trioxonitrate V -------->Tin IV nitrate + silver

a sample of ammonia contains 9g hydrogen and 42g nitrogen. another sample contains 5g hydrogen .calculate the amount of nitrogen
balandron [24]
9 g of hydrogen - 42 g of nitrogen
5 g of hydrogen - x g of nitrogen

9x=42 \cdot 5 \\
9x=210 \\
x \approx 23.33

The mass of nitrogen in the second sample is 23.33 g.

The instructions for the experiment direct you to prepare 30 mL of 1.5 M HCl solution. In the chemical closet, you locate an 18M
MAVERICK [17]

The volume of the 18M HCl needed to make the solution will be 2.5 mL.

<h3>Dilution</h3>

According to the dilution principle, the number of moles of solutes in a solution before and after dilution must remain the same.

Since, mole = molarity x volume

Thus, molarity x volume before dilution = molarity x volume after dilution.

Mathematically, the equation is written as: m1v1 = m2v2

In this case, m1 = 18 M, m2 = 1.5 M, and v2 = 30 mL.

What we are looking for is v1, the amount of the stock HCl needed for dilution.

v1 = m2v2/m1 = 1.5 x 30/18 = 2.5 mL.

Thus, 2.5 mL of the stock HCl would be needed.

Photochemical chlorination of pentane gave a mixture of three isomeric monochlorides. The principal monochloride constituted 46%
meriva

Answer:

Explanation:

In the chlorination of alkanes, the condition necessary is UV light so free radical substitution can take place. For alkanes like pentane, the primary, secondary and tertiary Hydrogen atoms (Hydrogen atoms bonded to their respective carbon) þare taken into consideration and this is because the tertiary Hydrogen is the most reactive (due to bond dissociation energy) hence the easiest to be substituted. The trend is as follows in the order of their reactivity;

1° < 2° < 3°

So, the products of the chlorination of pentane, the principal monochloride constituted is 3 - chloropentane while the other two monomers are:

2- chloropentane

1- chloropentane

Below is the attachment showing the structural formula of the three monochloride constituted pentane.

Novay_Z [31]

A molecular property of the Group 6A(16) hydrides changes abruptly down the group. This change has been explained in terms of a change in orbital hybridization can see a similar difference in Group 15 as well where the same thing influences stability through bond strength (decrease in bond dissociation enthalpy down the group).

We can see a similar difference in Group 15 as well where the same thing influences stability through bond strength (decrease in bond dissociation enthalpy down the group). The change is a significant decrease in \textbf{bond angle}bond angle. Down the group we're observing increase in size as well as decrease in electronegativity which causes position of bond pairs of electrons to shift more and more away from the central atom. That then causes a decrease in repulsion between bonded pairs which results in a decrease in bond angle hydrides.
