Answer:

Boron

Explanation:

You can find this by looking at the number of protons in Boron, 5.

Then calculate how many electrons you are given, in this case the 2 core plus the 3 valence equal 5 total electrons

Neutral elements have the same number of protons and electrons, so your answer would be the element with 5 electrons, Boron.

You can also know this by using electron configuration. Since you kow there are 5 electrons then you can use EC to find out where your element is. In this case it is: 1s2 2s2 2p1

Liquid A is known to have a lower surface tension and lower viscosity than Liquid B. Use these facts to predict the result of be

Korvikt [17]

Answer: Option (B) is the correct answer.

Explanation:

Surface tension is defined as the attractive forces experienced by the surface molecules of a liquid by the molecules present beneath the surface layer of the liquid.

And, viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.

Since, it is given that viscosity of liquid B is more than liquid A. Therefore, liquid B has more resistive force on its surface as compared to liquid A. As a result, time taken by liquid B is more than time taken by liquid A.

Also, Surface tension = $\frac{Force}{Length}$

Surface tension of liquid B is more than liquid A. Therefore, $F_{B} > F_{A}$ .

Thus, we can conclude that tA will be less than tB.

Match each of the substances with the expected pH of the resulting solution when they are added to neutral water. Determine if a

Tamiku [17]

To determine the expected pH of the resulting solution of the following substances, create a balanced chemical equation of their ionization in water:

HI

HI + H2O ---> H+ + I-

It completely dissociates into H+ and I-. Due to the presence of the Hydronium Ion, the solution is acidic.

KBr

KBr + H2O ----> HBr + KOH

The salt KBr is formed by a strong base and a weak acid, therefore, the solution it forms with water is basic.

LiOH

LiOH + H2O ----> Li+ + OH-

It dissociates completely in water, turns into Li+ and OH-. Due to the presence of Hydroxide Ion, the solution becomes basic.
