<span>This is a false statement. While a solution in water might have a strong or weak electrolyte, there are also occasions where it might contain a non-electrolyte. Two examples of these types of solutions that will not be electrolytic would be a sugar solution or ethanol.</span>

Describe something that is not matter. What characteristics is it lacking?

lara31 [8.8K]

<h3><u>Answer; </u></h3>

Energy such as heat light, are examples of non matter

<h3><u>Explanation;</u></h3>

Matter is anything that occupies space and has weight and mass. It is also tangible, and visible.
Not everything is matter, others such as heat and light are not matter, they are non-matter, This is because they are not tangible, they lack weight, they also lack atoms or molecules, but they are form of energy.
Therefore, energy such as heat, and light are non matters

Which metalloid has three valence electrons? boron arsenic silicon lithium<br><br><br> HElp PLEase

Sever21 [200]

Answer:

Boron

Explanation:

First, locate the metalloids on the periodic table. (First picture) The metalloids are in the yellow section. Next, remember that the group your element is in determines its valence electrons. For example, group 17/7A has 7 valence electrons. Look at the group numbers above each column on the periodic table to find out which metalloid is the answer. In this case, we need to look at 13/3A since we know that this metalloid has three valence electrons. Not all periodic tables will be labeled with the 3A part, so remember that groups 13 and over have the amount of valence electrons after you take out the one in front. For example, group 16 has 6 valence electrons because I removed the one in front of it. Now your options should be limited down to boron because we know that it is in the yellow section in group 13.

What is the new temperature when 10 L at 5 K is compressed to 4.00 L

lina2011 [118]

Answer: C

Explanation:

For this problem, we would use Charles's Law. We fill in what we are given and solve.

Charles's Law: $\frac{V_{1} }{T_{1} } =\frac{V_{2} }{T_{2} }$

$\frac{10 L}{5K} =\frac{4.00L}{T_{2} }$

$10T_{2}= 20$

$T_{2}=2K$

As you increase the temperature of a solute it's solubility

photoshop1234 [79]

There would be a direct result as an increase in the solute temperature will result in increase in its solubility. A greater amount of solute molecules will possess more kinetic energy and will be distributed and in container.
