Answer:

Not sure if you still need help, but here ya go. I'm not going to rewrite the chemical names, so this is the order of answers.

P2H6

NO3

N4H6

Explanation:

Just gotta break down the names and look at the roots. I'll walk through the first one.

ex) Diphosphorus hexahydride:

Di means two, and Phosphorus means just that, phosphorus. So we have two phosphorus, represented by P on the periodic table. So, P2

Hexa means 6, and hydride means hydrogen. We know this because we take the part of the word before 'ide' to get hydr, the first part of hydrogen.

Thus, we have six hydrogen, represents by an H on the periodic table. So, H6

Put it together, we have P2H6

Just have to do that to all the other ones. Look at the prefix to get the number of atoms, then the suffix to know what the atom is. That being said, KNOW YOUR PREFIXES or this gets really hard.

note: metals, if compound is ionic, are always first in the name

A gas has a volume of 45.0 mL and a pressure of .98 atm. If the pressure increased to 2.1 atm and the temperature remained the s

goblinko [34]

Answer: The new volume is 95.45 mL.

Explanation:

Given: $V_{1}$ = 45.0 mL, $P_{1}$ = 0.98 atm

$P_{2}$ = 2.1 atm, $V_{2}$ = ?

According to Boyle's law, at constant temperature the pressure of a gas is inversely proportional to its volume.

Therefore, formula used to calculate the new volume is as follows.

$\frac{P_{1}}{V_{1}} = \frac{P_{2}}{V_{2}}$

Substitute the values into above formula as follows.

$\frac{P_{1}}{V_{1}} = \frac{P_{2}}{V_{2}}\\\frac{0.98 atm}{45.0 mL} = \frac{2.1 atm}{V_{2}}\\V_{2} = 95.45 mL$

Thus, we can conclude that the new volume is 95.45 mL.

21. Which type of reaction is shown below?

Anvisha [2.4K]

The correct answer is B) Double displacement.

This is because the Barium (Ba), which has a positive charge, got rearranged to bond with the carbonate (CO3), which has a negative charge. Also, the potassium (K), which has a positive charge, bonded with the chlorine (Cl), which has a negative charge.

It helps to remember that when there is a double replacement there are 4 elements/molecules in the reactants and 4 in the products that get rearranged.

Hope this helps!

Cis-4-tertButylcyclohexyl bromide (compound 1) and Trans-4 tert Butylcyclohexylbromide (compound 2) are reacted with Potassium T

Mkey [24]

Answer:

In compound 1 the Tert butyl group occupies the equatorial position and the Bromine occupies the axial position and in compound 2 the Tert butyl occupies the axial and the bromine occupies equatorial positions. Compound 1 reacts faster than compound 2.

Explanation:

In cyclic organic compounds, substituents may occupy the axial or equatorial positions. The axial positions are aligned parallel to the symmetry axis of the ring while the equatorial positions are around the plane of the ring.

Bulky substituents have more room in the equatorial than in the axial position. This means that compound 1 is more stable than compound 2.

This is clear on the basis of stability of the molecules because compound 1 will react faster than compound 2 since the bulky tertiary butyl group in compound 1 occupy equatorial and not axial positions.
