Which statement correctly compares ice and liquid water?

Chemistry
1 answer:
Evgen [1.6K]2 years ago

Answer:

B. Particles of liquid water have more energy than particles of ice.

Explanation:

We can work this out through eliminating the wrong statements.

A. Both liquid water and ice have definite shapes.

This is wrong because, as stated in the question, water is a liquid, and one of the properties of liquids is that they change shape to fit the shape of their container. If it changes shape, it does not have a "definite" shape.

B. Particles of liquid water have more energy than particles of ice.

This is correct, and here is why. There are 3 states of matter: solid, liquid and gas. As you apply heat energy to an object at each state, the particles receive more energy and can move around more (this is kinetic energy). In the case of liquid (water) and solid (ice), particles in solids do not have much energy and stay in rigid formations. They do vibrate slightly, but only on the spot (this is what gives solids "definite" shapes). On the other hand, particles in liquids have more energy than particles in solids, which means that they can move more (more kinetic ENERGY) and do not stay in formations (this is why they do not have "definite" shapes). Therefore, particles in liquids (water) have more energy than particles in solids (ice), and this statement is correct.

C. Liquid water has a lower temperature than ice.

This is wrong because liquids have more energy than solids. As explained earlier, the reason why particles in liquids have more energy is because more HEAT energy has been applied to them. In the same way, solids have less energy because less HEAT energy has been applied to them. Less heat means a lower temperature. (Also you can use common sense for this one, ice feels colder than liquid water, right?)

D. Ice has a definite volume, but liquid water does not.

This is wrong because of the law of conservation of mass. This law states that particles (or matter or volume) cannot be created or destroyed. When ice melts and becomes liquid water, it has not lost volume: the particles have just gained more energy. This question is most likely there to confuse you, because all substances have definite volumes.

I hope this helps!

Carbon can form large number of organic compounds why
Vinvika [58]

Answer:

Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

Oxalic acid can remove rust (Fe2O3) caused by bathtub rings according to the reaction Fe2O3(s) - 6H2C2O4(aq) rightarrow 2Fe(C2O4
Katena32 [7]

<u>Answer:</u> The mass of rust that can be removed is 1.597 grams

<u>Explanation:</u>

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}     .....(1)

Molarity of oxalic acid solution = 0.1255 M

Volume of solution = 6.00\times 10^2mL = 600 mL = 0.600 L    (Conversion factor:  1 L = 1000 mL)

Putting values in equation 1, we get:

0.100M=\frac{\text{Moles of oxalic acid}}{0.600L}\\\\\text{Moles of oxalic acid}=(0.100mol/L\times 0.600L)=0.06mol

For the given chemical reaction:

Fe_2O_3(s)+6H_2C_2O_4(aq.)\rightarrow 2Fe(C_2O_4)_3^{3-}(aq.)+3H_2O(l)+6H^+(aq.)

By Stoichiometry of the reaction:

6 moles of oxalic acid reacts with 1 mole of ferric oxide (rust)

So, 0.06 moles of oxalic acid will react with = \frac{1}{6}\times 0.06=0.01mol of ferric oxide (rust)

To calculate the mass of rust for given number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Molar mass of rust (ferric oxide) = 159.7 g/mol

Moles of rust = 0.01 moles

Putting values in above equation, we get:

0.01mol=\frac{\text{Mass of rust}}{159.7g/mol}\\\\\text{Mass of rust}=(0.01mol\times 159.7g/mol)=1.597g

Hence, the mass of rust that can be removed is 1.597 grams
