Answer: 10 grams of Hydrogen gas will be produced theoretically.

Explanation: The equation for the reaction between zinc metal and hydrochloric acid is:

Zn(s)+2HCl(aq.)\rightarrow ZnCl_2(aq.)+H_2(g)

As HCl is present in excess, therefore limiting reagent is Zinc metal as it limits the formation of product.

By stoichiometry,

1 mole of Zinc metal produces 1 mole of Hydrogen gas, therefore

\text{5 moles of Zinc metal will produce}=\frac{1}{1}\times 5=5\text{ moles of Hydrogen gas}

Amount of Hydrogen gas produced can be calculated by:

\text{Mass of gas produced}=\text{Moles}\times \text{Molar mass}

Molar mass of Hydrogen = 2 g/mol

Mass of hydrogen gas produced = (5 moles )× (2 g/mol)

Mass of hydrogen gas produced = 10 grams

Which conclusion is consistent with the following net ionic equation? co2+(aq) + s2-(aq) cos(s)
PolarNik [594]

The conclusion that is consistent with the ionic equation would be that COS (s) is a precipitate.

<h3>What is a precipitation reaction?</h3>

It is a reaction in which 2 soluble salts in aqueous forms react to produce an insoluble salt as one of the reaction's products.

Precipitate products are usually insoluble and can be filtered off using suitable filter paper. In other words, they are solids that are suspended in solution.

Following the ionic reaction, the two reacting ions are in aqueous forms while the product formed is solid.

Which two wire properties would provide the greatest resistance to the flow of a current? short, thin long, thin hot, thick cool
Nat2105 [25]

The two properties which provide the greatest resistance to the flow of a current are the long and thin wires.

<h3>What is resistance?</h3>

Resistance is the quantity which define the flow of current from any wire and it is represented as:

R ∝ l/A, where

l = length of wire

A = cross section of wire

From the relation it is clear that resistance is high in long wire and thin wire.

So, required properties are long and thin.

.....k+.....HgCl2 gives u...... Hg+ KCl
worty [1.4K]

Answer:

2K + HgCl2 —> Hg + 2KCl

Explanation:

K + HgCl2 —> Hg + KCl

The above equation is not balanced

To balance the equation, do the following.

First, put 2 in front of KCl, the equation becomes,

K + HgCl2 —> Hg + 2KCl

Now we see that Cl is balanced but K is not. To balance K, put 2 in front of K as shown below:

2K + HgCl2 —> Hg + 2KCl

Now we can that the equation is balanced
