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.

Why does the temperature remain constant during melting till all the ice has melted?

GenaCL600 [577]

All the energy goes into melting the ice. Ice and water are at equilibrium during melting, so the temperature does not change.

Once all the ice has melted to water, the temperature will rise.

Hydrogen gas and nitrogen gas react to form ammonia gas. What volume of ammonia would be produced by this reaction if 5.53 mL of

lina2011 [118]

Answer:

5.53 mL of hydrogen will produce 3.6867 mL of Ammonia

Explanation:

The complete balance equation for the given reaction is

N2 + 3H2 --> 2 NH3

Thus, 3 moles of hydrogen produces 2 moles of NH3

Hence, the volume of ammonia produced = 5.53 * (2/3) = 3.6867 mL

Hence, 5.53 mL of hydrogen will produce 3.6867 mL of Ammonia

An element has 35 protons, 36 electrons, and 45 neutrons. This is called a(n)

Gre4nikov [31]

Protons and neutrons are particles that make up the dense nucleus at the center of an atom. Protons have a positive electric charge, and neutrons have no electric charge (i.e., neutrons are electrically neutral).

Electrons are particles that are found surrounding the nucleus; electrons have a negative electric charge.

The magnitude of a proton's positive charge and an electron's negative charge are equal in magnitude. All they differ in is in their polarity.

So, an atom that has the same number of protons and electrons would be electrically neutral. An ion is an atom that has a non-neutral charge because of an imbalance between the number of protons and electrons. If there are more electrons than protons, there is a net negative charge, and this type of ion is called an anion; if there are fewer electrons than protons, there is a net positive charge, and this type of ion is called a cation.

In this case, we have an element (or, more precisely, an atom of an element) that has 35 protons, 36 electrons, and 45 neutrons. There is one more electron than there are protons. This is called an anion because there are fewer electrons compared to protons.
