what happen when a piece of silver metal is added to the copper sulphate solution​

Answers

Answer:

Explanation:When silver Ag metal is added to copper sulphate CuSO4 solution, no reaction takes place as silver is less reactive than that of copper and cannot displace copper from its solution. Hence, when a piece of silver metal is added to copper sulphate solution there will be no reaction.

Answer:

There will be no reaction

Explanation:

Therefore, when silver Ag metal is added to copper sulphate CuSO4 solution, no reaction takes place as silver is less reactive than that of copper and cannot displace copper from its solution. Hence, when a piece of silver metal is added to copper sulphate solution there will be no reaction.

A.The radii of the atoms are represented by the symbol of the atom surrounded by dots in the
space-filling model.

B.The radii of the spheres in a space-filling model are proportional in size to the radil of the atoms
they represent

C.The radii of the atoms present in the compound determine the length of the bonds in a space-
filling model.

Answers

Answer:

Option B, In a space-filling model of a molecule, the radii of the spheres in a space-filling model are proportional in size to the radii of the atoms

they represent

Explanation:

In a space-filling model of a molecule, atoms are represented as sphere. The radius of the sphere is equal to the radius of the atom and the distance between the center of one sphere to the center of other represents the distance between the atomic nuclei

Option B is correct

Option A is incorrect, as dots are used in the space filling model to represent the atoms

Option C is incorrect because radii of atom do not represents the length of the bonds in a space-  filling model

Are electron shells or orbitals actually inside the atom or are they outside of the structure of the atom?

What’s the mass of 1.5 moles of c6h14

Answers

12*6 = 72
1*14 = 14
1.5 * (72+14)
Answer = 129

Answer:

[tex]\boxed {\boxed {\sf 129.267 \ g \ C_6H_{14}}}[/tex]

Explanation:

To convert from moles to mass, the molar mass is used. This is the grams per mole for a substance.

The values are found on the Periodic Table. They are the same as the atomic masses, but the units are grams per mole instead.

We are given this compound: C₆H₁₄. Look up the molar masses for the individual elements first: carbon and hydrogen.

C: 12.011 g/mol H: 1.008 g/mol

Check the subscripts, which tell us the number of atoms per molecule.  There are 6 carbon atoms and 14 hydrogen atoms. Multiply the molar mass by that number, then add them together.

C₆: 12.011*6=72.066 g/mol H₁₄: 1.008*14=14.112 g/mol C₆H₁₄: 72.066+14.112=86.178 g/mol

Use the molar mass as a ratio.

[tex]\frac {86.178 \ g \ C_6H_{14}}{1 \ mol \ C_6H_{14}}}[/tex]

Multiply by 1.5 moles.

[tex]1.5 \ mol \ C_6H_{14} \times \frac {86.178 \ g \ C_6H_{14}}{1 \ mol \ C_6H_{14}}}[/tex]

The moles of C₆H₁₄ will cancel each other out.

[tex]1.5 \times \frac {86.178 \ g \ C_6H_{14}}{1}}[/tex]

[tex]1.5 \times {86.178 \ g \ C_6H_{14}}[/tex]

[tex]129.267 \ g \ C_6H_{14}[/tex]

1.5 moles of C₆H₁₄ is equal to 129.267 grams of C₆H₁₄

What mass of NaOH is in 250 mL of a 3.0M NaOH solution​

Answers

Explanation:

Explanation: It's a 3.0 M solution so 1 litre of solution contains 3 moles of NaOH. 250 ml of solution therefore contains 0.25 x 3 = 0.75 moles of NaOH. The molar mass of NaOH is 39.9971 g/mol, so 250 ml of this solution contains 0.75 x 39.9971 = 29.99 g, or if you round it up 30.0 g.

30g of NaOH is in 250 mL of a 3.0M NaOH solution​.

What is Mole?

The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter.

A mole is defined as the amount of substance containing the same number of atoms, molecules, ions, etc. as the number of atoms in a sample of pure 12C weighing exactly 12 g.

Given,

Volume of NaOH = 250 ml

Concentration = 3M

number of moles = concentration × volume (L)

= 3 × 0.25

= 0.75 moles

mass = moles × molar mass

= 0.75 × 40

= 30 g

Therefore, 30g of NaOH is in 250 mL of a 3.0M NaOH solution​.
