Answer: The average kinetic energy of water at 25^{o}C is 1.233 \times 10^{-26} J.

Explanation:

Given: Temperature = 25^{o}C = (25 + 273) K = 298 K

Kinetic energy is the energy acquired by the molecules of a substance due to its motion.

Formula to calculate average kinetic energy is as follows.

K.E = \frac{3}{2}kT

where,

T = temperature

k = Boltzmann constant = 1.38 \times 10^{-23} J/K

Substitute the value into above formula as follows.

K.E = \frac{3}{2}kT\\= \frac{3}{2} \times 1.38 \times 10^{-23} J/K \times 298 K \\= 1.233 \times 10^{-26} J

Thus, we can conclude that the average kinetic energy of water at 25^{o}C is 1.233 \times 10^{-26} J.

Reacting 35.4 ml of 0.220 m agno3 with 52.0 ml of 0.420 m k2cro4 results in what mass of solid formed
laila [671]
Answer is: 1.29 grams <span>of solid formed.
</span>Chemical reaction: 2AgNO₃(aq) + K₂CrO₄(aq) → Ag₂CrO₄(s) + 2KNO₃(aq).
n(AgNO₃) = c(AgNO₃) · V(AgNO₃).
n(AgNO₃) = 0.220 M · 0.0351 L.
n(AgNO₃) = 0.0078 mol; limiting reactant.
n(K₂CrO₄) = 0.420 M · 0.052 L.
n(K₂CrO₄) = 0.022 mol.
From chemical reaction: n(AgNO₃) : n(Ag₂CrO₄) = 2 : 1.
n(Ag₂CrO₄) = 0.0078 mol ÷ 2.
n(Ag₂CrO₄) = 0.0039 mol.
m(Ag₂CrO₄) = 0.0039 mol · 331.73 g/mol.
m(Ag₂CrO₄) = 1.29 g.

Equilibrium is reached in chemical reactions when: A) The rates of the forward and reverse reactions become equal. B) The concen
kap26 [50]

Answer:

Correct option: A

Explanation:

Equilibrium means the state of reaction which there is no net changes occur it means the rate of forward reaction and rate of backward reaction become same and also it does not mean that the concentration of both side i.e. reactant and product become equal. after gaining equlibrium position the concentration of reactant and product remain same and also chemical reaction does not stop and it continues.
