What's the formula for distance?

nekit [7.7K]

There are several formulas for distance. The one you choose to use is the one that expressed distance in terms of the information that you already have. For example, if you already know the speed and the time you've been traveling, then the formula for the distance you've covered is D = (speed) times (time) .

A research team has just discovered a new element called Likhitium. Now they need to determine the average atomic mass in order

earnstyle [38]

The question is incomplete, the complete question is shown in the image attached to this answer.

Answer:

139.13

Explanation:

The average atomic mass of the element Likhitium is the sum of the relative abundance of all the isotopes of Likhitium.

We obtain the relative atomic mass of Likhitium as follows;

(44.7/100 * 138) + (52.3/100 * 139) + (0.5/100 * 140) + (2.5/100 * 141)

61.7 + 73.2 + 0.7 + 3.53 = 139.13

Hence the relative abundance of Likhitium is 139.13

What species is reduced in the reaction below?

lesya692 [45]

Answer: The correct option is D) $Ag^+$

Explanation:

The oxidation reaction is defined as the reaction in which a chemical species loses electrons in a chemical reaction. It occurs when oxidation number of a species increases.

A reduction reaction is defined as the reaction in which a chemical species gains electrons in a chemical reaction. It occurs when oxidation number of a species decreases.

For the given chemical reaction:

$Zn^0+2Ag^+\rightarrow Zn^{2+}+2Ag^0$

On the reactant side:

Oxidation number of Zn = 0

Oxidation number of Ag = +1

On the product side:

Oxidation number of Zn = +2

Oxidation number of Ag = 0

As the oxidation number of Ag is decreasing from +1 to 0. Thus, $Ag^+$ is getting reduced.

Hence, the correct option is D) $Ag^+$
