Answer:

34.44 g.

Explanation:

  • The balanced equation for the reaction is:

<em>Fe + S → FeS,</em>

<em></em>

<em>It is clear that 1.0 mol of Fe reacts with 1.0 mol of S to produce 1.0 mol FeS.</em>

<em />

  • We need to calculate the no. of moles of 60 grams of iron and 90 grams of iron sulfide:

no. of moles of Fe = mass/atomic mass = (60.0 g)/(55.845 g/mol) = <em>1.074 mol.</em>

<em>no. of moles of FeS = mass/molar mass</em> = (90.0 g)/(87.91 g/mol) = <em>1.024 mol.</em>

<u><em>∵ Fe reacts with S with (1: 1) molar ratio.</em></u>

∴ The no. of moles of S needed to react with Fe is 1.074 mol.

<em>∴ The no. of grams of S needed = no. of moles x molar mass </em>= (1.074 mol)(32.065 g/mol) = <em>34.44 g.</em>

sveticcg [70]

Answer:

Explanation: Volume versus Temperature: Raising the temperature of a gas increases the average kinetic energy and therefore the rms speed (and the average speed) of the gas molecules. Hence as the temperature increases, the molecules collide with the walls of their containers more frequently and with greater force.

Allisa [31]

Answer:

A.  5 N to the left

<em>Note: The question is incomplete. The complete question is given below:</em>

<em>With a force of 5 newtons, Amanda pushes the stack of books to the right. At the same time, Jeremy, her little brother, pushes the stack of books to the left with a force of 10 newtons. </em>

<em>What is the direction and magnitude of the resulting force? </em>

<em>A.  5 N to the left </em>

<em>B.  5 N to the right </em>

<em>C.  10 N to the right </em>

<em>D.  10 N to the left </em>

Explanation:

Forces are vector quantities.

Vector quantities are quantities that can be represented both in magnitude and direction.

Forces have both magnitude and direction. Forces can be directed positively or negatively.

For example, in the question above, if forces acting to the right are considered to be in the positive direction, forces acting to the left are considered to be acting in a negative direction.

In the addition of forces, both their magnitude and direction are taken into consideration.

In the example above, taking forces acting to the right as positive and to the left as negative, the sum of the forces is:

Resultant force, F = (5 N) + (-10N)

F = -5 N

Therefore, the net force is 5 N and is directed towards the left
