Which is an example of a covalent bond? Chlorine accepts an electron from calcium to form a stable bond. Ions in a bar of pure i

ron are surrounded by a large number of valence electrons. There are less than 16 valence electrons in 2 chlorine atoms, but they form a stable bond.

Answer:

There are less than 16 valence electrons in 2 chlorine atoms, but they form a stable bond

Explanation:

A covalent bond occurs between nonmetal elements, or between a nonmetal and hydrogen or between hydrogen atoms. In this kind of bond, the atoms share electrons.

In the first case, chlorine is accepting electrons from calcium, which is donating. Chlorine is a nonmetal, but calcium is a metal. They form an ionic bond.

In a metal bar, like iron, there are metallic bonds: the metal loses electrons, and the cation (the metal ion) is surrounded by these electrons.

So, in a bond between two chlorine atoms, both nonmetal, there is a sharing of electrons. Both have 7 electrons in the valence shell, and each one shares one electron. They both will have 8 electrons, but the total will be 14 electrons, less than 16.

Gallium chloride is formed by the reaction of 2.25 L of a 1.50 M solution of HCl according to the following equation: 2Ga 6HCl -
Setler79 [48]

Answer:

198.56g of GaCl3

Explanation:

We'll begin by calculating the number of mole HCl in 2.25 L of a 1.50 M solution of HCl. This is illustrated below:

Molarity of HCl = 1.50 M

Volume = 2.25 L

Mole of HCl =..?

Molarity = mole /Volume

1.5 = mole /2.25

Cross multiply

Mole = 1.5 x 2.25

Mole of HCl = 3.375 mole

Next, we shall determine the number of mole Gallium chloride, GaCl3 produced from the reaction. This is shown below:

2Ga + 6HCl —> 2GaCl3 + 3H2

From the balanced equation above,

6 moles of HCl reacted to produce 2 moles of GaCl3.

Therefore, 3.375 mole of HCl will react to produce = (3.375 x 2)/6 = 1.125 mole of GaCl3.

Therefore, 1.125 moles of GaCl3 were produced from the reaction.

Next, we shall convert 1.125 mole of GaCl3 to grams. This is illustrated below:

Molar mass of GaCl3 = 70 + (35.5x3) = 176.5g/mol

Mole of GaCl3 = 1.125 mole

Mass of GaCl3 =..?

Mole = mass /Molar mass

1.125 = mass of GaCl3 /176.5

Cross multiply

Mass of GaCl3 = 1.125 x 176.5

Mass of GaCl3 = 198.56g

Therefore, 198.56g of GaCl3 were produced from the reaction.

A car travels at 35.0 mi/hr. How far has it gone in 2455 seconds?
Vika [28.1K]

Answer:

<h3>The answer is 23.8 miles</h3>

Explanation:

The distance covered by an object given it's velocity and time taken can be found by using the formula

<h3>distance = velocity × time</h3>

From the question

velocity = 35.0 mi/hr

time = 2455 s = 0.68 hr

We have

distance = 35 × 0.68

We have the final answer as

<h3>23.8 miles</h3>

Hope this helps you
