Answer:

First, write an equation for the reaction involved.

Fe + CuSO4 ---> FeSO4 + Cu

Now, calculate the no. of moles added in the reaction. (n.o.m. = mass /molar mass)

No. of moles of Fe added = 2 / 55.8

= 0.0358 mol

No. of moles of CuSO4 = 7 / (63.5 +32.1+16x4)

= 0.04386 mol

From the equation, the mole ratio of Fe : CuSO4 = 1:1,

meaning 1 mole of Fe reacts with 1 mole of CuSO4.

It also indicates that the no. of moles reacted in Fe equals to the no. of moles reacted in CuSO4.

0.04386 > 0.0358

The no. of moles of CuSO4 is higher than that of Fe, meaning all moles of Fe will be reacted while not all CuSO4 reacts.

Hence Fe is the limiting reagent, and CuSO4 is in excess.

All 0.0358 moles of Fe reacts, meaning the no. of moles of CuSO4 left unreacted = 0.04386 - 0.0358

= 0.0080596mol

mass of CuSO4 unreacted = 0.0080596 x (63.5 +32.1+16x4)

= 1.28g

he combustion of propane (C3H8) is given by the balanced chemical equation C_3H_8+5O_2\longrightarrow3CO_2+4H_2O C 3 H 8 + 5 O 2
Basile [38]

Answer:

290 grams

Explanation:

Let's begin by writing the balanced chemical equations:

C_{3}H_{8} +5O_{2} --->3CO_{2} +4H_{2}O

Then we calculate the number of moles in 97g of propane.

n(propane)=\frac{mass}{molarmass} =\frac{97g}{44.1g/mol}=2.1995mol

According to the balanced chemical equation, one mole of propane produces 3 moles of carbon dioxide. So the available number of moles of propane must be multiplied by three to work out the number of carbon dioxide produced.

n(carbon dioxide)= 2.1995mol*3 = 6.5985mol

mass(carbon dioxide) = moles * molar mass

                                   = 6.5985 mol * 44.01 g/mol

                                   = 290 grams

What is responsible for moving the water to the ground?
Mandarinka [93]

Answer:

Water applied to the surface of a relatively dry soil infiltrates quickly due to the affinity of the soil particles for water. As time passes and the soil becomes wet, the force of gravity becomes the dominant force causing water to move.
