a chemist dissolves 0.564 moles of manganese (IV) oxide (MnO2) in water, and adds enough water to make 0.510 L of solution. Calc

ladessa [460]

Answer:

The molarity of the solution is 1.1 $\frac{moles}{liter}$

Explanation:

Molarity is a measure of the concentration of that substance that is defined as the number of moles of solute divided by the volume of the solution.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

$molarity=\frac{number of moles of solute}{volume}$

Molarity is expressed in units $\frac{moles}{liter}$

In this case

number of moles of solute= 0.564 moles
volume= 0.510 L

Replacing:

$molarity=\frac{0.564 moles}{0.510 L}$

Solving:

molarity= 1.1 $\frac{moles}{liter}$

<u><em>The molarity of the solution is 1.1 </em></u> $\frac{moles}{liter}$ <u><em></em></u>

Name the type of organic compound from each description of the functional group: (b) group that is not polar and has a double bo

krek1111 [17]

Some of the crucial functional groups in organic compounds are the hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl groups. The formation of molecules including DNA, proteins, carbohydrates, and lipids depends heavily on these groups.

<h3>What is Function Group ?</h3>

In organic chemistry, a functional group is a collection of atoms within molecules that interact to cause predictable reactions. Functional groups include the hydroxyl, ketone, amine, and ether groups, for instance.

(b) Most double bonds, such those found in alkenes, are formed when two carbon atoms are present. In a carbonyl group, for instance, where a carbon atom and an oxygen atom are together, there are several double bonds connecting the two separate components. Sulfoxides (S=O), imines (C=N), and azo compounds (N=N) also include common double bonds.

Which of the statements about elements is true?

Jet001 [13]

1. No two elements have the same kind of atom.

Explanation:

The correct of all statement is that no two elements have the same kind of atoms.

Every element have different atoms.

Over a hundred elements have been identified by scientists.
Atoms are the smallest particles that takes part in chemical reactions.
Elements are distinct substances that cannot be split.
Atoms of all elements do not have the same mass and volume. Isotopes are examples.
It is true that atoms of all elements have different masses and also different volumes.
The volume of an atom is function of the number of electrons it contains.
