Answer:

Um... 6

Explanation:

C6H12O6

The O is oxygen and the 6 is the exact number of atoms

Answer:

ion-dipole interaction

Explanation:

Ethanol is a polar molecule due to the presence of the polar O-H group in the molecule. This means that the molecule has a dipole moment.

The positive end of the dipole lies on hydrogen while the negative end of the dipole lies on oxygen.

When KCl is dissolved in ethanol, K^+ ions can interact with the negative end of the dipole in ethanol by ion-dipole interaction.

Explanation:

An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element, with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H+ cation and the anion of the acid.

Answer:

there are 5 molecules in SO⁴

Answer:

(C5H7)8

Explanation:

It's empirical formula is given as; C5H7

Molar mass of carbon(C) = 12 g/mol

Molar mass of hydrogen(H) = 1 g/mol

We are told that it's molar mass is 536 g/mol.

To find the molecular formula;

Molecular formula = n × empirical formula

Thus;

n = 536/((12 × 5) + (1 × 7))

n = 8

Thus;

Molecular formula = (C5H7)8

Answer: Filtration technique

Explanation:

The technique used here is called filtration.

Filtration,is a physical separation process that separates a mixture of an insoluble solid from a liquid ( acting as the solvent) by the use of a filter barrier that allows only the fluid to pass through.

In the case from the question,

As water is poured over the ground coffee, it forms a mixture of which the insoluble solid is the coffee grounds, the water is the liquid and the filter barrier is the piece of paper which allows only the brown liquid coffee to pass through as the filtrate.

Answer:

41.88375 g Fe

Explanation:

Using stoichiometry, we can do this problem. First, we put our given. Then we create an equation using the molar mass of Fe (found on the periodic table, which was 55.845 g Fe), and the resulting equation is:

[tex]0.75 mol Fe * \frac{55.845 g Fe}{1 mol Fe}[/tex]

The mol Fe's cancel, and leave us with:

41.88375 g Fe

Good luck.

Answer:

C. 80g Nano3 at 10 degrees Celsius

Explanation:

I just took the test

80 g NaNO₃ at 10 degrees Celsius of a compound dissolved in 100 grams of water at the stated temperature represents a system at equilibrium. Therefore, option C is correct.

What is solubility ?

The maximum quantity of a chemical that will dissolve in a given amount of solvent at a particular temperature is referred to as its solubility.

Different compounds have very varying solubilities, which is a feature of a particular solute-solvent pair.

A substance's physical and chemical characteristics affect how soluble it is. A few other factors and circ*mstances can also influence it. A few of these are: temperature, pressure, kind of binding, and forces between the particles.

A system is said to be in equilibrium when 80 grammes of a substance, dissolved in 100 grams of water at 10 degrees Celsius.

Thus, option C is correct.

Answer:

Water is the answer

Explanation:

Answer:

1. Gases can be easily liquefied into very small volumes and stored in liquid form Eg in LPGA cylinders and used in homes.

2. Balloons can be easily filled with air.

The fact that a gas is easily compressible is applied in the colling devices such as air conditioners as well as in the pumping of tyres with air.

Are gases compressible?

Gases are easily compressible because they do not have a definite volume. This is positively applied in many areas of life.

Answer:

Explanation:

Step One

Find the molar Mass of NH3

N = 14

3H = 3

Mass = 17

Step Two

Find the number of moles of NH3

mols = given mass / Molar Mass

given mass = 824 grams

molar mass = 17

mols = 824/17

mols = 48.47

Step Three

Find the moles of NO

Here you have to look at the balanced equation

Every 2 mols of HN3 produces 2 mols of NO

So the number of mols of NH3 = 48.47

The number of mols of NO = 48.47

Step Four

Find the mols of H2O

2 mols of NH3 produces 3 moles of H20

48.47 mols H20 produces x moles of H20

3/x = 2/48.47 Cross Multiply

2x = 3*48.47

2x = 145.41 Divide by 2

x = 145.41/2

x = 72.71 mols of water.

Answer:

Cobaltous Nitride,I think so anyway.......

The formula name for [tex]Co_{3}N_{2}[/tex] is cobalt(II) nitride.

In the compound [tex]Co_{3}N_{2}[/tex], the Co represents the chemical symbol for cobalt, and the N represents the chemical symbol for nitrogen. The subscript numbers indicate the ratio of atoms present in the compound.

To name the compound, we determine the charge of the cobalt ion based on the ratio of cobalt and nitrogen atoms. In this case, since there are three cobalt atoms and two nitrogen atoms, each cobalt atom has a 2+ charge.

Therefore, the correct name for [tex]Co_{3}N_{2}[/tex] is cobalt(II) nitride. The Roman numeral II is used to indicate the cobalt ion's charge.
