When is an isotope considered stable?<br> (Select all that apply.)

GaryK [48]

Explanation:

A stable isotope is one that does not emit radiation, or, if it does its half-life is too long to have been measured. It is believed that the stability of the nucleus of an isotope is determined by the ratio of neutrons to protons.

Hope this helps you out : D

A liquid has a density of 0.87g/ml. What volume is occupied by 25g of liquid

irga5000 [103]

Answer:

29 mL

Explanation:

<h3>Equation</h3>

The question needs us to find the volume of the liquid. The equation for volume using density and mass is:

Volume = Mass / Density

<h3>Solve</h3>

We can substitute the given values for density and mass into the equation:

$V=\frac{25\ g}{0.87\ g/ml}$

$V\approx29\ mL$

<h3>Additional Comments</h3>

The answer we obtained (29 mL) is rounded to two significant figures. When multiplying or dividing, the amount of significant figures in the final answer is always the least amount of significant figures in one of the values.

Below are the significant figure rules:

Nonzero digits will always be significant (eg. 54 --> 2 significant figures)

Zeroes at the beginning of a number will never be significant (eg. 0.1 --> 1 significant figure)

Zeroes between two nonzero digits will always be significant (eg. 504 --> 3 significant figures)

Zeroes following a number will always be significant if the number contains a decimal point (eg. 40.0 --> 3 significant figures)

The volume of the granite as

Trava [24]

The volume of the granite as determined by water displacement is 9.35 mL. This value in cm³ is 9.35cm³.

<h3>How to calculate volume in cm³?</h3>

The conversion factor of mL and cm³ is given as follows: 1 mL = 1 cm³

According to this question, the volume of the granite as determined by water displacement is 9.35 mL.

This value in cm³ can be converted as follows:

9.35mL × 1 = 9.35cm³

Therefore, the volume of the granite as determined by water displacement is 9.35 mL. This value in cm³ is 9.35cm³.

Which statement correctly compares ice and liquid water?

Evgen [1.6K]

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!
