Answer:

Explanation:

<u><em>A proton is a subatomic particle, symbol p or p⁺, with a positive electric charge. elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are collectively referred to as "nucleon"</em></u>

<u><em>The neutron is a subatomic particle, symbol n, with no net electric charge and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms. Since protons and neutrons behave similarly within the nucleus, and each has a mass of approximately one atomic mass unit, they are both referred to as nucleons. Their properties and interactions are described by nuclear physics.</em></u>

The best method for seperating a salt from water is

abruzzese [7]

Answer:1 Boiling

Explanation:

Salt (Solute) + water (solvent) = Solution.

Salt dissolves in water, therefore, the only way to recover the salt is by boiling (evaporation) the solution.

At 304 K, a 9.6 L tank contains 1.9 moles of H2 gas under an unknown pressure in atm. What is the pressure of the gas in the tan

ratelena [41]

Answer:

The pressure is 4.939 atm

Explanation:

As we know

PV = nRT

where P is the pressure

V is the volume

n is the total number of moles

R is the gas constant

and T is the temperature

Substituting the given values we get -

$P * 9.6 = 1.9 * 0.0821 *304\\P = 47.420/9.6\\P = 4.939$

The pressure is 4.939 atm

What is Keq for the reaction N2 + 3H2 2NH3 if the equilibrium concentrations are [NH3] = 3 M, [N2] = 1 M, and [H2] = 2 M?

Licemer1 [7]

Answer : The correct option is, (D) $k_{eq}=1.125$

Explanation : Given,

Concentration of $NH_3$ = 3 M

Concentration of $N_2$ = 1 M

Concentration of $H_2$ = 2 M

The given balanced equilibrium reaction is,

$N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)$

The expression for equilibrium constant for this reaction will be,

$K_{eq}=\frac{[NH_3]^2}{[N_2][H_2]^3}$

Now put all the given values in this expression, we get the value of $K_{eq}$

$K_{eq}=\frac{(3)^2}{(1)\times (2)^3}$

$K_{eq}=1.125$

Therefore, the value of $K_{eq}$ for the given reaction is, 1.125
