Aloiza [94]3 years ago

There are more reactants than the products

Explanation:

For any system in equilibrium, the molar concentration of all the species on the right hand side is related to the molar concentrations of those at the left hand side by a constant known as the equilibrium constant (K_{eq}).

The constant is temperature dependent.

  • When the equilibrium constant is less than 1, it implies that there are more reactants than the products.
  • If the constant is equal to 1, the products and reactants are the same.
  • If the constant is greater than 1, the products are more than the reactants.

How much energy in joules, does it take to heat a 55 gram sample of ice from-10°C to
Lostsunrise [7]

Energy needed : Q = 1105.5 J

<h3>Further explanation</h3>

Given

mass = 55 g

Temperature from -10°C to 0°C

Required

Energy

Solution

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

Input the value :

Q = 55 g x 2.01 J/g ° C  x (0-(-10))

Q = 1105.5 J

Sodium sulfate dissolves as follows: Na2SO4(s) → 2Na+(aq) + SO42- (aq). How many moles of Na2SO4 are required to make 1.0 L of s
maxonik [38]

<u>Answer:</u> The number of moles of Na_2SO_4 is 0.05 moles.

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}

We are given:

Molarity of solution = 0.10 mol/L

Volume of solution = 1 L

Putting values in above equation, we get:

0.10mol/L=\frac{\text{Moles of sodium}}{1.0L}\\\\\text{Moles of sodium}=0.10mol

The chemical reaction for the ionization of sodium sulfate follows the equation:

Na_2SO_4(s)\rightarrow 2Na^+(aq.)+SO_4^{2-}(aq.)

By Stoichiometry of the reaction:

2 moles of sodium ions are produced by 1 mole of sodium sulfate

So, 0.10 moles of sodium ions will be produced by = \frac{1}{2}\times 0.1=0.05moles of sodium sulfate.

Hence, the number of moles of Na_2SO_4 is 0.05 moles.
