How many grams of h20 is formed by mixing solutions containing 90.0 mol CuO and 18.01 mol NH3

Answer:

Redox reaction

Explanation:

Solid magnesium metal was added to aqueous zinc chloride. The zinc has a higher electronegativity than the magnesium and therefore attracts two electrons from magnesium, which gives magnesium a positive charge.

Carbon dioxide (CO2) lewis structure has two oxygen atoms and one carbon atom. There are two double bonds around carbon atom in the CO2. No lone pairs on carbon atom and each oxygen atom has two lone pairs on their valence shells. Shape of CO2 is linear.

The observation implies that the solubility of a solution depends on both the amount of solute and the volume of solvent.

The solubility of a substance is the property of that substance to dissolve in a solvent.

The solubility of a solution is the ability of the solution to dissolve solutes.

Solubility depends on the quantity of solutes and solvents.

Thus, 100 mL water may be able to dissolve 35 g NaCl but not 70 g because the maximum solubility of the water is breached. In order to dissolve more NaCl, the volume of the water might need to be increased.

Answer:

VII'th group, negative ion

Explanation:

Usually fluorine is located in the seventh(VII) group as fluorine has 7 electrons in it's outer shell with chemical symbol "F"
Fluorine has 7 electrons in it's outer shell therefore, it needs one more electron to get the noble gas configuration. So more electrons means negative ion.

The equilibria showing how the acetate buffer adjusts to addition of a small amount of NaOH is:

A buffer is a solution which resists changes to its pH when small amounts of strong base or acid is added to it.

Buffers are made from solutions of weak acids and their salts or weak bases and their salts.

The equilibria showing how a buffer made from acetic acid and sodium acetate (NaCH3COO) adjusts to addition of a small amount of NaOH is as follows:

Addition of NaOH, a strong base will neutralize the hydronium ion, causing the acetic acid ionization equilibrium to shift to the right to produce more of the acetate ion, the conjugate base.

Answer:

T=846K

Explanation:

We can use the formula for the Ideal Gas Equation, which is

[tex]PV=nRT[/tex]

P=pressure

V=volume

n=mols of gas

R=constant (0.08201 L-atm/mol-K)

T=temperature

We will have to rearrange to equation to find temperature, which is

[tex]T=\frac{PV}{nR}[/tex]

Time to solve:

[tex]T=\frac{(2.50 atm)(10.30L)}{(0.371 mols)(0.08206 L-atm/mol-K)}[/tex]

[tex]T=846 K[/tex]

If you want to convert to Celsius, subtract 273 to your answer, which will get you 573ºC.

According to Avogadro's law, the two gases will have equal number of molecules.

From the question, we are to determine how the two gases would compare according to Avogadro's law

First, we will state the Avogadro's law

Avogadro's law states that "equal volume of all gases at the same temperature and pressure contain the same number of molecules"

Now, from the given information

We have 2 liters of hydrogen gas and 2 liters of oxygen gas at the same temperature and pressure

According to Avogadro's law, gases that are equal in volume and are at the same temperature and pressure will have equal number of molecules.

Hence, according to Avogadro's law, the two gases will have equal number of molecules.

The new volume is mathematically given as

V=93.75ml

Question Parameters:

A gas with a volume of 250 mL has 16.0 moles

the number of moles is reduced to 12.0

Generally, the equation for the gas laws   is mathematically given as

V1/n1 = V2/n2

Therefore

250/16 = V2/12

v=375/4

V=93.75ml

In conclusion,  the new volume of gas is

V=93.75ml

Answer:

Protons = 17 Neutrons = 18 Electrons = 17

Explanation:

The number of protons and electrons are the the same number as the atomic number.

To get the number of neutrons, subtract the number of protons from the mass number.

35-17=18

Answer:

Protons: 17

Neutrons: 18

Electrons: 17

Explanation:

To find the number of protons, you simply have to find the atomic number of the element.

To find the number of protons you have to subtract the atomic number from the atomic mass

To find electrons to add or subtract the charge that the element has. (In this case, it has no charge)

Explanation:

Gaining of an electron is most exothermic for Fluorine.

N2(g)+O2(g)→2NO(g) is an endothermic response because heat is absorbed on this reaction. all of the other reactions are exothermic as the warmth is launched for the duration of the method.

Any manner that absorbs warmness from its environment is an endothermic system. consequently, all endothermic reactions are endothermic strategies. An endothermic reaction is any chemical response that absorbs warmth from its surroundings. The absorbed electricity provides the activation electricity for the reaction to arise.

Fluorine is important for the manufacturing of nuclear material for nuclear power vegetation and for the insulation of electrical towers. Hydrogen fluoride, a compound of fluorine, is used to etch glass. Fluorine, like Teflon, is used to make plastics and is also essential in dental fitness.

Acidic

Considering the definition of pH,  the pH is lower than 7, so the solution is basic.

pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:

pH= - log [H⁺]

The numerical scale that measures the pH of substances includes the numbers from 0 to 14. The pH value 7 corresponds to neutral substances. Acidic substances are those with a pH lower than 7, while basic substances have a pH higher than 7.

In this case,[H⁺]= 1×10⁻⁵ M.

Replacing in the definition of pH:

pH= - log (1×10⁻⁵ M)

Solving:

pH= 5

Finally, the pH is lower than 7, so the solution is basic.

Answer:

Pentane

Explanation:

This is a little hard to look at and figure out what's going on, but I think I got the gist of it. Hydrocarbon naming is fairly simple. They are essentially named based on how many carbons make up the "skeleton." The prefix denotes how many there are, and as we can see, there are five hydrocarbons.

Hex- means six, so this is not correct.

Hept- is not one we see quite often, but it is seven, which again is not correct.

Oct- is eight. Still not five.

Pent- means five. And there you go, there is the answer.
