Handle of frying pan would be a good use for a nonmetal. A nonmetal is neither a good thermal insulator nor a good electrical conductor. Because it is neither, it can be use as a semiconductor. It does not absorb heat that much that is why it is best in insulating.

Answer: Option (a) is the correct answer.

Explanation:

Non-metals are the substance which are electron deficient in nature. They are also brittle and bad conductors of heat and electricity.

Whereas electrical wires, structural components in buildings, and coinage requires good conductors of heat and electricity. Therefore, metals being good conductors of heat and electricity are suitable for them.

Hence, we can conclude that handle of frying pan would be a good use for a non-metal.

A 8.249 gram sample of copper is heated in the presence of excess fluorine. A metal fluoride is formed with a mass of 13.18 g. D
levacccp [35]

Answer:

CuF_2 the empirical formula of the metal fluoride.

Explanation:

Mass of copper heated = 8.249 g

Mass of copper fluoride formed = 13.18 g

Mass of fluorine gas in copper fluoride = x

13.18 g = 8.249 g + x\\x= 13.18 - 8.249 g = 4.931 g

Moles of copper :

= \frac{8.249 g}{63.546 g/mol}=0.1298 mol

Moles of fluorine:

= \frac{4.931 g}{18.998 g/mol}=0.2596 mol

For the empirical formula divide the smallest mole of an element with all the moles of elements present in the compound.

Copper= \frac{0.1298 mol}{0.1298 mol}=1\\Fluorine = \frac{0.2596 mol}{0.1298 mol}=2

The empirical formula of the copper fluoride = CuF_2

CuF_2 the empirical formula of the metal fluoride.

How do tidal bulges form?
Troyanec [42]

Answer: The pull of the moon's gravity on Earth's water causes tidal bulges to form on the side closest to the moon and farthest from the moon. In the place where there are tidal bulges, high tide occurs along coastline.

Someone please help? I've had a go at this myself (see picture of working attached) but not sure where to go from there?
DiKsa [7]

Answer:

75 ml of 0.1M  base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion

but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH

which means the formula for the acid must be H3A and

the value of x in

HxA is 3

Explanation:

75ml of a solutipn of 0.1moL  l-1 NaOH neutralises 25ml of a solution of an acid. The formula of the acid is HxA and the concentration of the acid is 0.1mol l-1. What is the value of x?​

the concentration of both the and the base are the same at 0.1M

the base...NaOH has 0.1 moles/L of OH ion

75 ml of 0.1M  base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion

but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH

which means the formula for the acid must be H3A and the value of x in

HxA is 3

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. For example, if you are asked to add 14.3 g
tensa zangetsu [6.8K]

Answer: Set with equal densities are:

15.2 g copper and 50.0 g copper ; 11.2 g gold and 14.9 g gold

Explanation:

Density is defined as mass of the substance present in unit volume of the substance.

Density=\frac{Mass}{Volume}

It is an intensive property which means that two different masses of same substance will have same value of density under same conditions.

So, from the given samples with equal density are:

  • 15.2 g copper and 50.0 g copper will have the same value density.
  • 11.2 g gold and 14.9 g gold will have the same value density.
