Answer:

Explanation:

The Proton number for flourine will be 9

Then the mass number which will be protons+ neutrons will be 19

Argon which has a mass number of 40

to find the proton number of argon it will be 40-22=18

then the electron number will just be the same as proton number

then calcium the proton will be the same as electron so it will be 20

then neutrons will be mass number -proton number

which is 21

hope this helped

Answer:Examples of physical change include changes in the size or shape of matter. Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting

Explanation:

Answer:

Not exactly But you can take the slope of the curved portion and the slope of the flatline.

It wont do you much good since your working for absorbance but if you ever see something like a temperature change you can use the slope(s) to find freezing points/melting

Explanation:

If you need to submit a slope you could use a best fit which is just point to point or you could break it up like i mentioned

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.)

Answer:

An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals

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:

1.00 mol

Explanation:

Step 1: Given data

Molecules of water: 6.02 × 10²³ molecules

Step 2: Calculate the number of moles corresponding to 6.02 × 10²³ molecules of water

In order to convert molecules to moles, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.

6.02 × 10²³ molecules × 1 mol/6.02 × 10²³ molecules = 1.00 mol (we keep 3 significant figures)

Explanation:

Answer:

It is liquid at most temperatures on Earth.

The answer is 290.66 mL

Explanation:

The density of any substance including styrofoam is determined by two main factors: mass (atoms in the substance) and volume (space occupied). Moreover, the volume or mass of the substance can be calculated by using the density as these variables are related. Below I show the process:

density = mass / volume

mass = density x volume

volume = mass / density

volume = 21.80 g / 0.075 g/mL

volume = 290.66 mL

Answer: A) The amount of product measured after a reaction

A statement which best defines the actual yield of a reaction is "The amount of product measured after a reaction" Hence, Option (A) is correct

Yield of any chemical reaction gives idea about the amount of product that is produced by the chemical reaction between reactants.

Actual yield gives idea about the how much yield of any product will be produced in the given chemical reaction by using the stoichiometry of the reaction.

Therefore, A statement which best defines the actual yield of a reaction is "The amount of product measured after a reaction" Hence, Option (A) is correct

Answer: The compound is [tex]Fe_2(SO_4)_3[/tex]

Explanation:

Molar mass is defined as the mass in grams of 1 mole of a substance.

S.I Unit of Molar mass is gram per mole and it is represented as g/mol.

A. 1 mole of [tex]Al(NO_3)_3[/tex] weighs = 26.98(1)+14.01(3)+15.99(9) =212.99 g/mol

B. 1 mole of [tex]C_3H_8[/tex] weighs = 12.01(3)+1.007(8) = 44.1 g/mol

C. 1 mole of [tex]Fe_2(SO_4)_3[/tex] weighs = 55.84(2)+32.06(3)+15.99(12) = 399.91 g/mol

D. 1 mole of [tex]CaCl_2[/tex] weighs = 40.07(1)+35.5(2)= 110.98 g/mol

Thus the compound is [tex]Fe_2(SO_4)_3[/tex]

Answer:

pH = 7.14.

Explanation:

Hello there!

In this case, since the pH of a solution is computed via the negative logarithm of the concentration of hydrogen ions:

[tex]pH=-log([H_3O^+])[/tex]

Therefore, we plug in the given concentration to obtain:

[tex]pH=-log(7.2x10^{-8})\\\\pH=7.14[/tex]

Which is a nearly-neutral solution.

Answer:

the answer would be 9,448.8

The mass of 9.3 × 10¹⁶ lead atoms is equal to 0.032 mg.

Avogadro’s number represents the number of entities in one mole of any substance. Generally, these units can be molecules, atoms, ions, electrons, or protons, depending upon the type of chemical reaction or reactant and product.

The value of Avogadro’s constant is approximately equal to 6.022 × 10²³ mol⁻¹.

Given, the number of atoms of the lead =  9.3 × 10¹⁶

The atomic mass of the lead = 207.2 g/mol

So 6.022 × 10²³ atoms of lead have mass = 207.2g

Then 9.3 × 10¹⁶ lead atoms will have mass [tex]=\frac{207.2\times 9.3\times 10^{23}}{ 6.022\times 10^{23}}[/tex]  = 31.998 ×10⁻⁷g

As we know, 1 gram = 1000 mg

The mass of the  9.3 × 10¹⁶ lead atoms =  31.998 ×10⁻⁴ mg = 0.0032 mg

Therefore, the mass of 9.3 × 10¹⁶ lead atoms is  0.032 mg.
