1. Prokaryotic, eukaryotic
2. Humans are eukaryotes. Like all other eukaryotes, human cells have a membrane-bound organelles and a definite nucleus
3. Bacteria are microorganisms made up of a single prokaryotic cell. There are two general categories of cells: prokaryotic and eukaryotic. Sometimes, organisms are referred to as prokaryotes or eukaryotes, based on the type of cell(s) that compose them.
4. Three similarities between prokaryotic and eukaryotic cells are that both have vesicles, vacuoles, and the ability to carry out the eight functions of life.

What is the molarity of a nitric acid solution if 43.13 mL 0.1000 M KOH solution is needed to neutralize 30.00 mL of the acid so

Leno4ka [110]

Answer:

0.144M

Explanation:

First, let us write a balanced equation for the reaction. This is illustrated below:

HNO3 + KOH —> KNO3 + H20

From the equation,

nA = 1

nB = 1

From the question given, we obtained the following:

Ma =?

Va = 30.00mL

Mb = 0.1000M

Vb = 43.13 mL

MaVa / MbVb = nA/nB

Ma x 30 / 0.1 x 43.13 = 1

Cross multiply to express in linear form

Ma x 30 = 0.1 x 43.13

Divide both side by 30

Ma = (0.1 x 43.13) /30 = 0.144M

The molarity of the nitric acid is 0.144M

The reaction is run at two temperatures where temperature 1 is lower than temperature 2. Which relationship is correct for eithe

Tasya [4]

Answer:

The answer is " $K_1 < K_2$ "

Explanation:

In the given question, the value of the $K=Ae^{-\frac{Ea}{RT}}$ and the $T_1$ is the rate value which is the constant that is $K_2>K_1$ . As per the temperature value when its increase rate is constantly increasing. $E_a$ is activation energy it is not dependent on the temperature that why the answer is $K_1 < K_2$ .
