What is the relationship between an objects mass and potential energy

Chemistry
1 answer:
Andrei [34K]3 years ago
5 0

Answer:

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

How much heat is absorbed when 30.00 g of C(s) reacts in the presence of excess SO2(g) to produce CS2(l) and CO(g) according to
Gnoma [55]

Answer:

120.0 kJ

Explanation:

  • First we convert the given mass of C to moles:

30.00 g C ÷ 12g/mol = 2.5 mol

  • The ΔH° value given by the problem, is the heat absorbed when 5 moles of C react.

So when we have<u> half the moles of C</u> (2.5 instead of 5.0), t<u>he heat absorbed will also be half</u>, thus the answer is:

  • 239.9 kJ / 2 = 120.0 kJ

The density of copper is 8.94 g/cm3. An irregular shaped sample of metal is 14 g and displaces a volume of 2.98 mL. (a) Find the
Vedmedyk [2.9K]

Explanation:

<h2>(a).</h2>

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of metal = 14 g

volume = 2.98 mL = 2.98 cm³

It's density is

density =  \frac{14}{2.98}  \\  = 4.69798657...

We have the answer as

4.70 g/cm³

<h2>(b).</h2>

The metal is not copper since it's density is less than that of copper.

Hope this helps you

Bond [772]

Answer:

Explanation:

The melting point of a substance is the temperature at which its melt. The state of a substance is dependent on it's melting temperature. Generally, melting point above 25 °C is a solid.

This means phenol is a solid

Duodecane has melting point below 25 °C hence it is either a liquid or gas. However its boiling point of 216 °C means it would require higher temperature to boil it. Since 25 °C is less than 216 °C it means that it would remain in the liquid state.

Methane has melting point below 25 °C hence it is either a liquid or gas. However its boiling point of -164 °C means it boils easily even at very low temperatures. Since 25 °C is greater than -164 °C it means that it would exist in the gaseous state
