Answer:

Option A = 2.2 L

Explanation:

Given data:

volume of one mole of gas = 22.4 L

Volume of 0.1 mole of gas at same condition = ?

Solution:

It is known that one mole of gas at STP occupy 22.4 L volume. The standard temperature is 273.15 K and standard pressure is 1 atm.

For 0.1 mole of methane.

0.1/1 × 22.4 = 2.24 L

0.1 mole of methane occupy 2.24 L volume.

Answer:

2,2 L

Explanation:

Under normal conditions of temperature and pressure: 273 K and 1 atm. The formula is used:

PV= nRT

R= Regnault constant

1 atm x  V = 0,1mol x 0,082 l atm/K mol x 273 K

V = (0,1mol x 0,082 l atm/K mol x 273 K)/ 1 atm

V= 2,2368 l

What can be said about a small Ksp value?
fredd [130]

Answer:

The correct answer is option B.

Explanation:

Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.

The equation for the ionization of the magnesium hydroxide is given as:

A_xB_y\leftrightharpoons xA^{y+}+yB^{x-}

                      xS      yS

Here, S = concentration of compound dissolved in solvent via dissociation

Expression for the solubility product of A_xB_y will be:

K_{sp}=[A^{y+}]^x[B^{x-}]^y\\\\K_{sp}=(xS)^x\times (yS)^y

As we can see,

K_{sp}\propto [S]

  • Higher the value of [S] more will be solubility of compound in a solvent.Hence, more soluble it will be.
  • Lower the value of [S] less will be solubility of compound in a solvent.Hence, less soluble it will be.

Hence, the correct answer is option B.

Can I get help with this, please!!

Pressure in the submarine when the temperature is changed to 293 K is 108.9 K Pa

Explanation:

Pressure in the submarine = 108.9 kPa

Volume, V = 2.4 * 10^5 L

Pressure, P = 116k Pa

Temperature, T = 312 K

Ideal gas law: PV = nRT  or  n = PV / RT

So, moles of gas, n =116 KPa * 2.4 * 10 ^5L / 8.314 LK Pa K^-1 *312 K

= 1.073 *10^4 mol

when temperature is changed to 293K,

PV = nRT  or P = nRT / V

=1.073 *10^4 mol *8.314 LK Pa mol^-1 K^-1 *293 K / 2.4*10^5L

=108.9 K Pa

Pressure in the submarine when the temperature is changed to 293 K is 108.9 K Pa

Calculate the theoretical yield of 1-bromobutane; base your calculations on using 1.0 g of 1-butanol (as the limiting reagent).
Tomtit [17]

C₄H₉OH + HBr = C₄H₉Br + H2O

Δmole of alcohol gives 1 mole of bromobutanol

HBr is in excess, so the yield of the product is limited by the alcohol

Wt. of 1 butanol = 18

Molar mass of the butanol = 74.12 g/mole

Moles of the alcohol = 1/74.12 = 0.01349 moles

So, moles of bromobutane = 0.01349 moles

Molar mass of C₄H₉Br = 137.018 g/moles

So, theoretical mass of bromobutane is = 0.01349 × 137.0.18

= 1.85 g
