Explanation:

The statement that explains whether NaCl or BeO will have a stronger bond is D. BeO will have a stronger bond because it has a smaller ionic charge, and a smaller distance between ions

A chemical bond simply means the attraction between ions, atoms, or molecules which then leads to the formation of chemical compounds.

It should be noted that Beryllium oxide with the chemical formula BeO has a stronger bond than Sodium Chloride due to the fact that it has a smaller ionic charge, and a smaller distance between ions

The concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution. The volume of 3M diluted solution of calcium hydroxide is 83.3ml.

Molarity can be calculated by dividing  number of moles of solute by volume of solution in litre. Molarity is affected by temperature. Its unit is mole/liter. It measure the concentration of any solute in a solution.

Mathematically,

According to the neutralization law,

M₁V₁=M₂V₂

where,

M₁ = molarity of stock  solution = 1 M

V₁ = volume of stock  solution = 250ml

M₂ = molarity of dilute  solution =3M

V₂ =  volume of dilute solution = ?

substituting all the given values we get

M₁V₁=M₂V₂

1 M×250ml=3M×V₂

V₂=83.3ml

Therefore, volume of 3M diluted solution of calcium hydroxide is 83.3ml.

A 57 grams sample of iron reacts with 24 grams of oxygen to form 81 grams of iron oxide.

Iron oxide is a chemical compound that is made by the addition of iron and oxygen can also be known as ferrous oxide if react with two oxygen molecules then ferric oxide.

In the sample, the iron is 57 grams and the oxygen is 24 grams,

                 Fe + O -------------> FeO

                Iron   oxygen            iron oxide

By adding the mass of iron and oxygen,

             57 + 24 = 81 grams of  iron oxide.

Therefore, the mass of iron oxide is 81 grams if 57 grams sample of iron reacts with 24 grams of oxygen.

Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent.

Explanation:

Answer:

To determine the correct subscripts in a chemical formula, you have to solve how many atoms you need to balance the charge.

For example if I had the compound Calcium Fluoride I would look at the periodic table and see that Calcium's ionic formula is

Ca2+

. How do I know this? Well all elements want to have 8 valance electrons so they can be stable(happy). Seeing that Calcium has 2 valance electrons it is going to give away 2 electrons because that is easier than gaining 6 to be happy. Since Calcium has given away 2 electrons it has two more protons than electrons. We know that Protons have a Positive charge, Electrons have Negative charge, and the number of electrons is equal to the atomic number of an element in its pure non-ionic state. (Meaning it doesn't have a positive or negative charge; it is balanced.)

So if calcium gave away two electrons, it will have two more protons than an electron giving it a (2+) charge. The same process can be applied to Fluoride. Since fluoride is one to the left of the noble gases(group 18 or 8A) on the periodic table we know that it has 7 valance electrons because it is in group 7A or 17.

Knowing that we have 7 electrons the fluoride atom will gain an extra electron. Since the fluoride atom gained an extra electron it will have one more negative charge than a positive making it a ^(−)ion.

So you know that Calcium has a 2+ charge and that fluoride has a 1- charge, you then need these ions to balance out. So you need two fluorine atoms with a 1- ions to balance out the 2+ ion of calcium. Your final answer would be

CaF2

because you need two fluorine atoms to balance out the 2+ charge of the calcium.

Final Tip: Determine the charges then inverse the charges, remove the positive and negative superscipts, and write the charge numbers as a sub script. Ie. Calcium Fluoride

Ca2+ and F−

inversing and removing the charge signs would give you

Answer:

6.00 moles of sodium permanganate

Explanation:

Let us attempt to count the number of atoms present in sodium perchlorate. The formula of the compound is NaClO4

Sodium atoms - 1

Chlorine atoms - 1

Oxygen atoms -4

Total number of atoms = 6

Among the options, only KMnO4 also has six atoms. One atom of potassium, one atom of manganese and four atoms of oxygen.

6.00 moles of sodium perchlorate contains the same number of atoms as: A. 6.00 moles of sodium permanganate.

First of all, we would determine the chemical formula and the number of atoms contained in each chemical compound as follows:

For sodium perchlorate:

Sodium perchlorate = [tex]NaClO_4[/tex]

[tex]NaClO_4[/tex] = [tex]1+1+2[/tex] = 6 atoms.

For sodium permanganate:

Sodium permanganate = [tex]KMnO_4[/tex]

[tex]KMnO_4[/tex] = [tex]1+1+2[/tex] = 6 atoms.

For strontium oxide:

Strontium oxide = [tex]SrO[/tex]

[tex]SrO[/tex] = [tex]1+1[/tex] = 2 atoms.

In conclusion, we can deduce that 6.00 moles of sodium perchlorate contains the same number of atoms as 6.00 moles of sodium permanganate.

A chemist prepares a solution of silver (I) perchlorate (AgCIO4) by measuring out 134.g of silver (I) perchlorate into a 50.ml volumetric flask and filling the flask to the mark with water. calculate the concentration in mol/L of the silver (I) perchlorate solution. Round your answer to 2 significant digits.

Answer:

13 mol/L

Explanation:

We must first obtain the number of moles of silver I perchlorate involved

Molar mass of silver I perchlorate = 207.32 g/mol

Number of moles of silver I perchlorate = 134g/207.32 g/mol = 0.646 moles

Recall that;

n =CV

C= concentration

V= volume

n = number of moles

C = n/V

C = 0.646 moles * 1000/50

C = 13 mol/L

Answer:

Molar mass of the unknown gas is 64.6 g/mol

Explanation:

Let's think this excersise with the Ideal Gases Law.

We start from the N₂. At STP conditions we know that 1 mol of anything occupies 22.4L.

We apply: P . V = n . R . T

5 atm . V = 1 mol . 0.082 . 325K

V = (1 mol . 0.082 . 325K) / 5 atm = 5.33 L

It is reasonable to say that, if we have more pressure, we may have less volume.

As this is the volume for 1 mol of N₂, our mass is 28 g. Then, the density of the nitrogen and the unknown gas is 28 g/5.33L = 5.25 g/L

Our unknown gas has, this density at 27°C and 2 atm.

If we star from this, again: 1 mol of any gas occupy 22.4L at STP, we can calculate the volume for 1 mol at those conditions:

P₁ . V₁ / T₁ = P₂ . V₂ / T₂

1 atm . 22,4L / 273K = 2 atm . V₂ / 300K

Remember that the value for T° is Absolute (T°C + 273)

[ (1 atm . 22.4L / 273K) . 300K] / 2 atm = V₂ → 12.3L

This is the volume for 1 mol of the unknown gas at 2 atm and 27°C

We use density to determine the mass: 12.3 L . 5.25 g/L = 64.6 g

That's the molar mass: 64.6 g/mol

Answer:

[tex]320.8329\ \text{g}[/tex]

[tex]\Rightarrow m=320.8329\ \text{g}[/tex]

The mass of the [tex]CO_2[/tex] gas will be [tex]320.8329\ \text{g}[/tex].

Answer:

You could use a hydrogen anion which has 2 electrons.

Explanation:

An ion is an atom or molecule with a net electric charge because it has more or less electrons compared to the original atom or molecule.

An anion is a negatively charged ion.

A cation is a positively charged ion.

Normally a hydrogen atom has one proton and one electron.

So a hydrogen anion (H-) means that it has one proton and two electrons, which means the positive charge will be +1 and the negative charge will be -2.

Ultimately, giving the entire molecule a net charge of -1 because -2+1 = -1.
