Answer:

Distillation

Explanation:

Water vaporizes at lower temperature than the ink pigment so if you heat them, the water evaporates, leaving the ink pigment in the flask

What controls the volumes of water in each cylinder once equilibrium is established?
netineya [11]

Equilibrium is a state of balance or a stable situation where the opposing forces cancel each other out and where no changes are occurring.

<h3>How to explain the equilibrium?</h3>

Your information is incomplete. Therefore, an overview will be given. In a chemical reaction, chemical equilibrium is a state where the reactants and products are present in concentrations that have no further tendency to change with time.

In terms of volume changes within a system at equilibrium, the following applies:

  • When there is a decrease in volume, then the equilibrium will shift to favor the direction that produces fewer moles of gas.
  • When there is an increase in volume, then the equilibrium will shift to favor the direction that produces more moles of gas.

In conclusion, if you increase the pressure of a system at equilibrium, the stress will be reduced by reaction that favors the side with the fewest moles of gas.

Four forces are exerted on an object as shown below:
Simora [160]

Answer:

B. Down

Explanation:

The left and right cancels out, because each direction is pulled with 2N.

There is more force pushing down than up, so the object will move down.

1. What is the net ionic equation for the reaction that occurs when aqueous solutions of AgNO3 and CaCl2 are mixed and a precipi
Sedbober [7]

Answer:

C. Cl^−_(_a_q_) + Ag^+_(_a_q_)->AgCl_(_s_)

Explanation:

In this question our options are:

A. Ca^+^2_(_a_q_)+NO_3^-_(_a_q_)->Ca(NO_3)_2_(_a_q_)

B. Ag^2^+_(_a_q_)+2Cl^-_(_a_q_)->AgCl_2_(_s_)

C. Cl^−_(_a_q_) + Ag^+_(_a_q_)->AgCl_(_s_)

D. None of the above because no reaction occurs

We have to remember that the <u>ions</u> produced by AgNO_3 are:

Ag^+  and NO_3^-

And the <u>ions</u> produced by CaCl_2 are:

Ca^+^2 and Cl^-

Additionally, we will have a <u>double displacement reaction</u> so the compounds produce are:

AgCl and Ca(NO_3)_2

If we remember the <u>solubility rules</u>, all the nitrate salts are soluble and the salts made with silver are not soluble. With this in mind, we will have a solid-state for AgCl_(_s_) and an aqueous state for  Ca(NO_3)_2_(_a_q_).

If this is true, the final answer can be B or C. <u>The charge of Ag is +1</u> so the final answer is C.

I hope it helps!

Describe how carbon and oxygen from carbon dioxide
MrRissso [65]

Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant's leaves. ... Animals and plants are connected to each other by the oxygen-carbon dioxide cycle.
