Answer:

The final pressure of the gas is:- 21.3 kPa

Explanation:

Using Boyle's law  

{P_1}\times {V_1}={P_2}\times {V_2}

Given ,  

V₁ = 10.0 L

V₂ = 45.0 L

P₁ = 96.0 kPa

P₂ = ?

Using above equation as:

{P_1}\times {V_1}={P_2}\times {V_2}

{96.0\ kPa}\times {10.0\ L}={P_2}\times {45.0\ L}

{P_2}=\frac {{96.0}\times {10.0}}{45.0}\ kPa

{P_2}=21.3\ kPa

The final pressure of the gas is:- 21.3 kPa

A gas is at 35.0°c and 3.50 l. what is the temperature at 7.00 l?
Degger [83]

Answer:

363C

Explanation:

V = KT  and T = V/K

3.5=k(35+273) = 308k

k=3.5/308 =0.011

new T=7.0/0.011=636K = 636-273 =363C

miskamm [114]

The reaction of 1-bromo-2-methylpropane (isobutyl bromide), (CH_3)_2CHCH_2Br, with Mg, and Et_2O results in the formation of an adduct of formula (CH_3)_2CHCH_2MgBr known as grignard reagent, an organometallic reagent, which on reacting with H_3O^{+} results in the formation of isobutane.

The reaction is shown in the image.
