4.65 L of nitrogen at standard pressure is compressed into a 0.480 L container. What is the new pressure in kPa?

Semenov [28]

Assuming that nitrogen gas is ideal, we can use the equation PV = nRT to relate first conditions to the second condition. At constant temperature, pressure and volume are indirectly related as follows:

P = k / V

k is equal nRT

P1V1 = P2V2
P2 = 101.325 ( 4.65 ) / .480 = 981.586 kPa

Rate law equation The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction betwe

shusha [124]

Answer: The reaction order with respect to A is m

Explanation:

Order of the reaction is defined as the sum of the concentration of terms on which the rate of the reaction actually depends. It is the sum of the exponents of the molar concentration in the rate law expression.

Elementary reactions are defined as the reactions for which the order of the reaction is same as its molecularity and order with respect to each reactant is equal to its stoichiometric coefficient as represented in the balanced chemical reaction.

For the given reaction:

$aA+bB\rightleftharpoons cC+dD$

$Rate=k[A]^m[B]^n$

In this equation, the order with respect to each reactant is not equal to its stoichiometric coefficient which is represented in the balanced chemical reaction.

Hence, this is not considered as an elementary reaction.

Order with respect to A = m

Order with respect to B = n

Overall order = m+n

Thus order with respect to A is m.

Determine the mass of 5.20 moles of C6H12 (gram-formula mass = 84.2 grams/mole).

SIZIF [17.4K]

5.20 mol C6H12* (84.2 g/mol C6H12)= 4.38*10^(2) g C6H12.

The answer should only have three significant figures, according to the numbers in the problem.

Hope this is helpful~

belka [17]

Answer: skeletal equation : $Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow NaNO_3(aq)+BaSO_4(s)$

The products are sodium nitrate and barium sulphate.

balanced equation : $Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow 2NaNO_3(aq)+BaSO_4(s)$

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The skeletal equation is:

$Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow NaNO_3(aq)+BaSO_4(s)$

The balanced chemical equation is:

$Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow 2NaNO_3(aq)+BaSO_4(s)$
