Answer: E)  In a closed system, the total energy always remains constant.

Explanation: For every system, the law of conservation of energy is applicable which states that the energy of the system remains conserved. Energy can neither be created nor destroyed.

A closed system is one which can exchange energy with the surroundings but not mass. Thus if a system absorbs energy, the equivalent amount of energy is lost by surroundings, thus the total energy remains constant.

If a system loses energy, an equivalent amount of energy is gained by surroundings, thus the total energy remains constant.

Summarize the various factors that affect a system at equilibrium. Then briefly explain how pressure can affect the equilibrium
True [87]

Answer:

The factors that affect the equllibrium are:

  • temperature,
  • pressure and
  • concentration.

Explaination:

<u>Effect of pressure:</u>

There is no effect of pressure if the number of moles on the gaseous reactants and the number of moles on gaseous products are equalized.However it is different for total no of gaseous reactants and  total no of gaseous products.

If the total no of moles on the reactants are more than total no of moles of products,then <em>low pressure</em> will favor the<u> forward reaction.</u>

If the total no of moles on the products is more than total the no of moles of reactants,then<em> high pressure</em> will favor the <u>forward reaction</u>

What is the molarity of a solution prepared by dissolving 12.0 g of sodium acetate, nac2h3o2, in water and diluting it to 250.0
amid [387]
Molarity is defined as the number of moles of solute in 1 L of solution 
the mass of sodium acetate added - 12.0 g 
molar mass of sodium acetate - 82 g/mol
number of moles = mass present / molar mass
number of moles of sodium acetate added = 12.0 g / 82 g/mol = 0.146 mol
the number of moles in 250.0 mL - 0.146 mol
therefore number of moles in 1000 mL - 0.146 mol / 250.0 mL x 1000 mL/L = 0.584 mol
there are 0.584 mol in 1 L - 0.584 mol/L
the molarity of sodium acetate is 0.584 M
