4 0

Answer:

<h2>Density = 1.6 g/mL</h2>

Explanation:

Density of a substance can be found by using the formula

Density =  \frac{mass}{volume}

From the question

mass = 145.8 g

volume = 91.75 mL

Substitute the values into the above formula and solve for the Density

That's

Density =  \frac{145.8}{91.75}

= 1.5891

We have the final answer as

Density = 1.6 g/mL

Hope this helps you

Which element, when combined with Iodine, would most likely form an ionic compound?
uranmaximum [27]

In an ionic compound the atoms are linked via ionic bonds. These are formed by the transfer of electrons from one atom to the other. The atom that loses electrons gains a positive charge whereas the atom that accepts electrons gains a negative. This happens in accordance with the octet rule wherein each atom is surrounded by 8 electrons

In the given example:

The valence electron configuration of Iodine (I) = 5s²5p⁵

It needs only one electron to complete its octet.

In the given options:

K = 4s¹

C = 2s²2p²

Cl = 3s²3p⁵

P = 3s²3p³

Thus K can donate its valence electron to Iodine. As a result K, will gain a stable noble gas configuration of argon while iodine would gain an octet. This would also balance the charges as K⁺I⁻ creating a neutral molecule.

Ans: Potassium (K)

How does the property of density help to identify substances?
Mashutka [201]

Answer:

Density can be useful in identifying substances. It is also a convenient property because it provides a link (or conversion factor) between the mass and the volume of a substance. Mass and volume are extensive (or extrinsic) properties of matter - they depend on amount.

A chemist determines by measurements that 0.0200 moles of chlorine gas participate in a chemical reaction. Calculate the mass of
Schach [20]

Answer:

1.4200 g

Explanation:

The chlorine gas has a molecular formula Cl2. In table periodic, the molar mass of one atom of chlorine is 35.5 g/mol, so the molar mass of Cl2 is 71 g/mol.

Molar mass, mass and number of moles are related by the equation below:

n = \frac{m}{MM}

Where n is the number of moles, m is the mass, and MM is the molar mass of the compound.

So, for 0.0200 moles of Cl2 produced:

0.0200 = \frac{m}{71}

m = 71x0.0200

m = 1.4200
