Answer:

0.384g/l

Explanation: the density version of the ideal gas law is pm=drt

in which p= pressure, m=molar mass,d=, density, r= to a constant which is 0.08206, and t=temperature so just input the values

PM=DRT. so to find d the formula would be D=RT\PM

D=<u>0.08206*242.5</u>

0.7311*70.90

D=0.384g/l

Which term is described as a long, narrow depression in the ocean floor?

ahrayia [7]

The term which is described as a long, narrow depression in the ocean floor would be ocean trench. They <span>are hemispheric-scale long but narrow topographic depressions of the sea floor. They are also the deepest parts of the ocean floor. Hope this answers the question.</span>

A hydrocarbon sample was burned in a bomb calorimeter. The temperature of the calorimeter and the 1.00 kg of water rose from 20.

fomenos

Answer:

The heat released by the combustion is 20,47 kJ

Explanation:

Bomb calorimeter is an instrument used to measure the heat of a reaction. The formula is:

Q = C×m×ΔT + Cc×ΔT

Where:

Q is the heat released

C is specific heat of water (4,186kJ/kg°C)

m is mass of water (1,00kg)

ΔT is temperature change (23,65°C - 20,45°C)

And Cc is heat capacity of the calorimeter (2,21kJ/°C)

Replacing these values the heat released by the combustion is:

<em>Q = 20,47 kJ</em>

An object with the mass of 2300 g has a force of 6.2 Newton's applied to it. What is the resulting acceleration of the object?

Triss [41]

Answer:

$\boxed {\boxed {\sf a\approx 2.7 \ m/s^2}}$

Explanation:

Force is equal to mass times acceleration.

$F=m*a$

By dividing both sides by m, we rearrange the formula for a (acceleration).

$\frac{F}{m} =a$

The force is 6.2 Newtons, but we can convert the units to make the problem easier later on.

A Newton is equal to 1 kg*m/s², so 6.2 N is equal to 6.2 kg*m/s².

The mass is 2300 grams, but we need to convert it to kilograms.

To convert grams to kilograms, divide by 1,000
2300 g/1000= 2.3 kg

$F= 6.2 \ kg*m/s^2\\m=2.3 \ kg$

Substitute the values into the formula.

$a=\frac{6.2 \ kg*m/s^2}{2.3 \ kg}$

Divide. Note that the kilograms or "kg" will cancel each other out (this is why we converted the units).

$a=\frac{6.2 \ m/s^2}{2.3 \ }$

$a=2.69565217 \ m/s^2$

Round to the nearest tenth. The 9 in the hundredth place tells us to round up to 2.7

$a\approx 2.7 \ m/s^2$

The acceleration is about <u>2.7 meters per second squared.</u>
