Copper (Cu) and silver (Ag) would not liberate hydrogen because they are less reactive than hydrogen since their standard reduction potential is higher.

Which statement describes global winds?
sergejj [24]

Answer:

They blow away from poles to the equator.

Explanation:

Hello,

In this case, we must take into account that global wind systems are formed by the constant increase in the temperature of the Earth’s surface. Thus, they drive the oceans’ surface currents. In such a way, we can say wind is the basic movement of air from an area of higher pressure to an area of lower pressure, for that reason they blow away from the poles to the equator.

Best regards.

Fe2O3 + CO → Fe + CO2 If 3 moles of Fe2O3 react with 1.5 moles of CO, how many moles of each product are formed? (3 points)
Dima020 [189]

Answer:

A. 1 mole of Fe.

B. 1.5 moles of CO₂.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

Fe₂O₃ + 3CO —> 2Fe + 3CO₂

From the balanced equation above,

1 mole of Fe₂O₃ reacted with 3 moles of CO to produced 2 moles of Fe and 3 moles of CO₂.

Next, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above,

1 mole of Fe₂O₃ reacted with 3 moles of CO.

Therefore, 3 moles of Fe₂O₃ will react with = 3 × 3 = 9 moles of CO.

From the calculation made above, we can see clearly that it will require a higher amount (i.e 9 moles) of CO than what was given (i.e 1.5 moles) to react completely with 3 moles of Fe₂O₃.

Therefore, CO is the limiting reactant and Fe₂O₃ is the excess reactant.

A. Determination of the number of mole of Fe produced.

NOTE: The limiting reactant is used to obtain the desired result because it will give the maximum yield of the products since all of it is consumed in the reaction.

From the balanced equation above,

3 moles of CO reacted to produced 2 moles of Fe.

Therefore, 1.5 moles of CO will react to produce = (1.5 × 2)/3 = 1 mole of Fe.

Thus, 1 mole of Fe was obtained from the reaction.

B. Determination of the number of mole of CO₂ produced.

From the balanced equation above,

3 moles of CO reacted to produced 3 moles of CO₂.

Therefore, 1.5 moles of CO will also react to produce 1.5 moles of CO₂.

Thus, 1.5 moles of CO₂ were obtained from the reaction.

REY [17]

Answer:

1st image, 17.79 g Mg(NO3)2

2nd image 1.47 mol NH3

3rd image Molar Mass Al(OH)3 = 78 g/mol

Explanation:

1st image

Molar Mass  Mg(NO3)2 = 148. 31 g/mol

0,12 mol Mg(NO3)2 x (148, 31 g Mg(NO3)2 / 1 mol Mg(NO3)2) = 17.79 gMg(NO3)2

2nd image

Molar Mass  NH3 = 17g/mol

25 g NH3 x ( 1 mol NH3/ 17 g NH3) = 1.47 mol NH3

3rd image

Molar Mass Al(OH)3 = 1 Al *(27) + 3 O * (16) + 3 H * (1) = 78 g/mol
