The new volume is mathematically given as

V2= 16.12 L

<h3>What is the new volume?</h3>

Question Parameters:

A sample of gas has an initial volume of 20 L

and an initial pressure of 2.5 atm.

If the pressure changes to 3.1 atm

Generally, the equation for Pressure   is mathematically given as

P1V1 = P2 V2

2.5 * 20 = 3.1 * V2

V2 = 50/3.1

V2= 16.12 L

Brilliant_brown [7]

Answer:

The first thing that you need to do here is to figure out the mass of the sample.

To do that, you can use its volume and the fact that aluminium is said to have a density of

2.702 g cm

−

3

, which implies that every

1 cm

3

of aluminium has a mass of

2.702 g

.

During a lab, you heat 1.62 g of a CoCl2 hydrate over a Bunsen burner. After heating, the final mass of the dehydrated compound
sashaice [31]
Answer is: formula of hydrate is CoCl₂· 6H₂O -c<span>obalt(II) chloride hexahydrate
</span>m(CoCl₂· xH₂O) = 1,62 g.
m(CoCl₂) = 0,88 g.
n(CoCl₂) = m(CoCl₂) ÷ M(CoCl₂)
n(CoCl₂) = 0,88 g ÷ 130 g/mol
n(CoCl₂) = 0,0068 mol.
m(H₂O) = 1,62 g - 0,88 g.
m(H₂O) = 0,74 g.
n(H₂O) = m(H₂O) ÷ m(H₂O) 
n(H₂O) = 0,74 g ÷ 18 g/mol
n(H₂O) = 0,041 mol.
n(CoCl₂) : n(H₂O) = 0,0068 mol : 0,041 mol.
n(CoCl₂) : n(H₂O) = 1 : 6.

He structure of the product, C, of the following sequence of reactions would be:
NikAS [45]

Answer:

I

Explanation:

The complete question can be seen in the image attached.

We need to understand what is actually going on here. In the first step that yields product A, the sodamide in liquid ammonia attacks the alkyne and abstracts the acidic hydrogen of the alkyne. The second step is a nucleophilic attack of the C6H5C≡C^- on the alkyl halide to yield product B (C6H5C≡C-CH3CH2).

Partial reduction of B using the Lindlar catalyst leads to syn addition of hydrogen to yield structure I as the product C.

For a reaction to occur, energy must be _____ to break chemical bonds.
lapo4ka [179]

Answer: The correct answer is absorbed.

Explanation:

Bond formation is a type of exothermic process. In these reactions when two atoms come close to each other, energy is released in this process.

On the other hand, in the breaking of bond, energy is required because the atoms are to be separated from each other. This is a type of endothermic process. So, the energy must be absorbed.

Hence, the correct answer is absorbed.
