Explanation:

The question is incomplete, the complete question is;

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:

C

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

Reaction 1 is the one that is different because there is only one product (option C).

In a reaction, there are two main components:

Moreover, a reaction can include two or more reactants as well as two or more products depending on the substances involved. Let's analyze reaction 1:

This means in this reaction there is only one product. This does not occur in reactions 2, 3, and 4 because in these there are two products.

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

Step 2: Calculate the force acting between the Earth and a 125-kg person standing on the surface of the Earth

We will use Newton's second law of motion.

F = m × g

F = 125 kg × 9.81 m/s²

F = 1.23 × 10³ N

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.

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.

(I hope this helps! I am not 100% sure what's the format of this question. Like is it interactive? online? Did you draw all those electrons on the diagram? or were they given? Are the numbers given as well? or did you type those in? So I just tried my best to give you something that might work.)
