A sample of gas occupies a volume of 67.1 mL . As it expands, it does 135.3 J of work on its surroundings at a constant pressure
Semmy [17]

Answer:

V_2=1.363x10^{-3}m^3=1363mL

Explanation:

Hello,

In this case, since the work done at constant pressure as in isobaric process is computed by:

W= P(V_2-V_1)

Thus, given the pressure, initial volume and work, the final volume is:

V_2=V_1+\frac{W}{P}

Whereas the pressure must be expressed in Pa as the work is given in J (Pa*m³):

P=783Torr*\frac{101325Pa}{760Torr} =104394Pa

And the volumes in m³:

V_1=67.1mL*\frac{1m^3}{1x10^6mL} =6.71x10^{-5}m^3

Thus, the final volume turns out:

V_2=6.71x10^{-5}m^3+\frac{135.3Pa*m^3}{104394Pa}\\\\V_2=1.363x10^{-3}m^3=1363mL

Best regards.

Suppose that 2.14 grams of H2SO4 is mixed with enough water to make 225 mL of solution. Determine the Molarity (M) of the soluti
Alik [6]

Answer:

0.0970 M

Explanation:

Remember this equation:

mol/M x V

Convert it so that you can get M.

M=mol/V

Convert the 2.14 grams of H2SO4 into mols

=0.0218

Convert mL to L

225/1000

=0.225

Plug it in.

0.0218/0.225

=0.0970 M

Define Neutralisation reaction along with examples.​
kaheart [24]

Answer:

Please find the definition and example of neutralization reaction below

Explanation:

In chemistry, neutralization reaction is a type of reaction involving a base and an acid to form salt and water. In other words, when an acid and a base comes together chemically to form a salt and water, a neutralization reaction is said to occur.

For example; in a reaction between sodium hydroxide (NaOH) and hydrogen chloride (HCl) as follows:

HCl(aq) + NaOH(aq) → NaCl(s) + H2O(l)

In this neutralization reaction, the HCk is the acid while the NaOH is the base (reactants). For the products, the NaCl is the salt while H2O is water.
