A force of 49 Newtons is applied to a rock, which causes it

Chemistry
1 answer:
Ket [755]2 years ago
3 0

Answer:

19.6Watts

Explanation:

Given parameters:

Force applied  = 49N

Distance  = 2m

Time  = 5s

Unknown:

Power  = ?

Solution:

Power is the rate at which work is being done;

   Power  = \frac{Work done }{time}

Work done  = force x distance  = 49 x 2 = 98J

So;

      Power  = \frac{98}{5}  = 19.6Watts

Molar mass is the mass of each element multiplied by subscript, then added together.

So, we’ll do

C = 12g x 12 = 144 g
H = 1g x 22 = 22 g
O = 16g x 11 = 176 g

The total of all of these is the molar mass: 342 g in a mol

The amount of mols of each element in each compound is likely equal to its subscripts.

C = 12 mols
H = 22 mols
O = 11 mols

For the atoms, you’ll multiply each one of the above by Avogadro’s number

Avogadro’s Number: 6.02 x 10^23 atoms/mol

The volume of a gas is 36.0 ml at 10.0°c and 4.50 atm. at what temperature (°c) will the gas have a pressure of 3.50 atm and a v
galben [10]
Using the combined gas law, where PV/T = constant, we first solve for PV/T for the initial conditions: (4.50 atm)(36.0 mL)/(10.0 + 273.15 K) = 0.57213.
Remember to use absolute temperature.
For the final conditions: (3.50 atm)(85.0 mL)/T = 297.5/T
Since these must equal, 0.57213 = 297.5/T
T = 519.98 K
Subtracting 273.15 gives 246.83 degC.
