Fe3N2, also known as Iron (II) nitride, is an ionic compound.

Ionic compounds are compounds that consists of metals and non-metals bonded with ionic bonds. The metal ion gives up electron(s) to the non-metals.

Since iron is a metal and nitrogen is an non-metal, the bond they would form would be an ionic bond. Iron gives up 2 electrons to form iron(II) ion, while nitrogen gains 3 electrons to form nitride ion. Since one iron cannot let a nitrogen gain 3 electrons, so in the compound, there would be 3 iron (ii) ions that has given up 6 electrons in total while 2 nitride ions have gained 6 electrons in total.

Write a balanced chemical equation for the fermentation sucrose (C12H22O11) by yeasts in which the aqueous ethyl alcohol (C2H5OH

kodGreya [7K]

Answer:

C12H22O11(aq) + H2O(l) —> 4C2H5OH(aq) + 4CO2(g)

Explanation:

When aqueous sugar (sucrose) react with water in the presence of yeast, the following products are obtained as shown in the equation below:

C12H22O11(aq) + H2O(l) —> C2H5OH(aq) + CO2(g)

Now, we shall balance the equation as follow:

There are a total of 24 atoms of H on the left side and 6 atoms on the right side. It can be balance by putting 4 in front of C2H5OH as shown below:

C12H22O11(aq) + H2O(l) —> 4C2H5OH(aq) + CO2(g)

There are a total of 9 atoms of C on the right side and 12 atoms on the left side. It can be balance by putting 4 in front of CO2 as shown below:

C12H22O11(aq) + H2O(l) —> 4C2H5OH(aq) + 4CO2(g)

Now the equation is balanced.

How many grams of HF are needed to react with 3.0 moles of Sn?

Flauer [41]

Answer:

120g

Explanation:

Step 1:

We'll begin by writing the balanced equation for the reaction.

Sn + 2HF —> SnF2 + H2

Step 2:

Determination of the number of mole HF needed to react with 3 moles of Sn.

From the balanced equation above,

1 mole of Sn and reacted with 2 moles of HF.

Therefore, 3 moles Sn will react with = 3 x 2 = 6 moles of HF.

Step 3:

Conversion of 6 moles of HF to grams.

Number of mole HF = 6 moles

Molar Mass of HF = 1 + 19 = 20g/mol

Mass of HF =..?

Mass = number of mole x molar Mass

Mass of HF = 6 x 20

Mass of HF = 120g

Therefore, 120g of HF is needed to react with 3 moles of Sn.

A gold nugget has a density of 38.6g/cm3 and a mass of 270.2. what is its volume?

aivan3 [116]

Density is given by the equation D=m/V, were D is density, m is mass in grams, and V is volume in cubic centimeters.

In this problem, we have density and we have mass so we can plug into the equation and solve for V.

38.6=270.2/V

*Multiply both sides by V*

38.6V=270.2

*Divide both sides by 38.6*

V=7

The volume of the gold nugget is 7cm3.

Hope this helps!!
