Please show the work :(What is the estimated force applied to the box if the acceleration is .40 m/s2?

lara31 [8.8K]

Answer:

20N

Explanation:

Given parameters:

Force(N) Acceleration(m/s²)

10 0.2

? 0.4

Unknown:

The force applied when the acceleration is 0.4m/s²

Solution:

From newton's second law of motion;

Force = mass x acceleration

Since we are using the same box, let us find the mass of the box;

Force = mass x acceleration

10 = mass x 0.2

mass = $\frac{10}{0.2}$ = 50kg

Now,

The force in the second instance will be;

Force = 50 x 0.4 = 20N

Determine how many gmol, kmol, and lbmols there are in 50 kilograms of n-hexane.

Artist 52 [7]

Answer: 581 gmol

0.581 kmol

$1.28\times 10^{-3}lbmol$

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{50\times 1000g}{86g/mol}=581mol$

1. The conversion for mol to gmol

1 mol = 1 gmol

581 mol= $\frac{1}{1}\times 581=581gmol$

2. The conversion for mol to kmol

1 mol = 0.001 kmol

581 mol= $\frac{0.001}{1}\times 581=0.581kmol$

3. The conversion for mol to lbmol

1 mol = $2.2\times 10^{-3}lbmol$

581 mol= $\frac{2.2\times 10^{-3}}{1}\times 581=1.28\times 10^{-3}lbmol$

Given the balanced equation representing a reaction: H2 → H + H What occurs during this reaction? 1. Energy is absorbed as bonds

RoseWind [281]

Answer : The correct option is, (2) Energy is absorbed as bonds are broken.

Explanation :

As we know that the bonds are formed and breaks during the chemical reaction. Some energy is released or absorbed when the bonds are formed and breaks during the chemical reaction.

During the bond breaking, some energy is required to break the bonds.

During the bond formation, some energy is released to the formation of the bonds.

In the given reaction, the bond between the hydrogen-hydrogen in $H_2$ are breaking into two hydrogen. That means during the bond breaking, some energy is required or absorbed to break the bonds.
