If you are walking down the street and a balanced force is exerted on you what will happen to your motion?
Anettt [7]
Balanced forces do not change the motion of an object. The motion of an object will not change if the forces pushing or pulling the object are balanced. An object that is sitting still will stay still if the forces acting on it are balanced.

What is the energy change when 78.0 g of Hg melt at −38.8°C
adell [148]

Answer:

The correct answer is - 2.557 KJ

Explanation:

In this case, Hg is melting, the process is endothermic, so the energy change will have a positive sign.

we can calculate this energy by the following formula:

Q = met

where, m = mass,

e = specific heat

t = temperature

then,

Q = 78*0.14* (273-38.8)

here 0.14 = C(Hg)

= 2.557 Kj

Determine the number of molecules in 3.79 kilograms of the fictional compound Cs7(Cr5O3)4. Include the units, but do not write t
Karo-lina-s [1.5K]

Answer:

1.0555 * 10^24 molecules

Explanation:

Number of molecules = ?

Mass = 3.79  Kg = 3790 g

Molar mass of Cs7(Cr5O3)4 = 2162.25 g/mol

Number of moles = Mass / Molar mass

Number of moles = 3790 g / 2162.25 g/mol

Number of moles = 1.7528 mol

1 mol = 6.022 * 10^23 molecules

1.7528 mol = x

solving for x;

x = 6.022 * 10^23 *  1.7528

x = 1.0555 * 10^24 molecules

You wash dishes for a chemistry laboratory to make extra money for laundry. You earn 12 dollars/hour, and each shift lasts 75 mi
PIT_PIT [208]
You calculate the amount of loads of laundry as follows:

((6 x 0.25)/ load) x 10 loads = 15.00 total cost required for laundry 

<span>(6.00 / 60 min) x (75 min/shift) = 7.50 cost / shift </span>

15.00 / (7.50 / shift) = 2 loads of  laundry

Hope this answers the question.
