A 800 kg car zooms away from a red light with an acceleration of 7.6 m/s2. What is the
aev [14]

Answer:

6080 N

Explanation:

From the question given above, the following data were obtained:

Mass (m) of car = 800 Kg

Acceleration (a) of car = 7.6 m/s²

Force (F) =?

The force experienced by the car can be obtained as illustrated below:

Force (F) = mass (m) × acceleration (a)

F = m × a

F = 800 × 7.6

F = 6080 N

Thus, the experience a force of 6080 N

For the reaction 2Fe + O2 = 2FeO, how many grams of iron oxide are produced from 8.00 mol of iron? when o2 is an excess
Yanka [14]

Answer:

The answer to your question is 576 grams of FeO

Explanation:

Balanced chemical reaction

                      2Fe  +  O₂  ⇒  2 FeO

       Reactant             Elements         Products

             2                         Fe                     2

             2                         O                       2

Data

mass of FeO = ?

moles of Fe = 8

Excess Oxygen

Process

1.- Convert moles of Fe to grams

Atomic mass = 56 g

                         56 g of Fe ------------------ 1 mol

                           x               ------------------ 8 moles

                           x = (8 x 56) / 1

                           x = 448 g of Fe

2.- Use the coefficients of the balanced reaction to find the grams of FeO.

Molecular mass of FeO = 2[ 56 + 16]

                                       = 144 g

               2(56) g of Fe ----------------------- 144 g of FeO

               448 g             -----------------------  x

                x = (448 x 144) / 2(56)

                x = 64512 / 112

               x = 576 grams of FeO
