The process of ___ occurs when a hydrate loses its water of hydration.a. effloresce
b. hydration
c. deliquescent
d. solvation

Answers

Answer 1
Answer:

Let us understand all the terms

Hydration : this is the addition of water to anything. It can be addition of water to double or triple bond, absorption of water by a substance. so it cannot be loss of water.

Deliquescent : it is the absorption of water by a substance and getting dissolved in it. Like NaOH is a deliquescent substance.

Solvation: It is the phenomenon where a substance get surrounded by solvent molecules. If solvent is water it is known as hydration.

Thus the answer is

effloresce : where a substance loses water.

26.0 g of a liquid that has a density of 1.44 g/mL needs to be measured out in a graduated cylinder. what volume should be used

Answers

Answer: The volume of liquid used will be 18.055 mL.

Explanation:

To calculate the volume of liquid, we use the equation for density which is:

\text{Density}=\frac{\text{Mass}}{\text{Volume}}

We are given:

Mass of the liquid = 26 g

Density of the liquid = 1.44 g/mL

Volume of the liquid = ? mL

Putting values in above equation, we get:

1.44g/mL=\frac{26g}{\text{Volume of the liquid}}\n\n\text{Volume of the liquid}=18.055mL

Hence, the volume of liquid used will be 18.055 mL.
As Density = Mass/Volume
Mass = 26.0g 
Density = 1.44g/mL
Therefore Volume = Mass/Density
=> Volume = 26.0/1.44 = 18.055... = 18.1mL (to 3 sig figs)

A voltaic cell is set up and a chemical reaction proceeds spontaneously. Which of the following will not occur in this reaction? a. The electrons will migrate through the wire
b. The cations in the salt bridge will migrate to the anode half-cell
c. The cathode will gain mass
d. The anode will lose mass
e. Reduction will occur at the cathode

Answers

d. anode will lose mass
because anode has negative charge and electrons loss by cathode will move to anode through a circuit to external wire

Suggest two reasons why the UK government wants to encourage recycling of iron and steel......

Answers

The two reasons why the UK government is encouraging citizens to recycle iron and steel is:
1.   The environment. Every machinery and device the industries makes which includes, infrastructures, mega structures to micro devices. Iron and steel is used. Reducing the extraction of ore and creating steel saves the environment, reduces mining.
2.   Economic reasons. When the ore mining and steel making is reduced in activity, the government won’t just be able to save the environment but it also save funds for other purposes.

In chemical equations, as long as all of the coefficients are the same on both sides of the equation, the equation is balanced.True
False

Answers

False. The subscripts have to be read and you must see if both sides have the same number of atoms.
This statement is false. Not only the coefficients must be balanced, the subscripts and also the number of elements must be equation on BOTH sides of the equation. That means that the reactants and products are equal, and unchanging.
