A rock weighing 2 newtons was lifted 3 meters. how much work was done

Chemistry
1 answer:
goblinko [34]3 years ago
3 0

Answer: The work done to lift the 2 N rock was 6 Joules.

Explanation:

Weight of the Rock = 2 Newtons

So, the force required to lift this rock will be equal to its weight or greater than its weight

Minimum force required to lift the Rock = 2 N

Displacement of the Rock when force was applied = 3 m,

Work Done: It is defined as product of force applied to the object into displacement of the object.

\text{Work done}=Force\times Displacement=2 N\times 3 m=6 Nm=6 Joules

The work done to lift the 2 N rock was 6 Joules.

How to convert butanoic acid to propanamide?​
netineya [11]

Butanoic acid is converted to propanamide by first converting it to propanoic acid, then ammonium propanoate and then finally propanamide by heating.

<h3>How are carboxylic acids converted to amides?</h3>

Carboxylic acids are converted to amides by converting them into into an ammonium salt which then produces an amide on heating.

The ammonium salt is prepared by adding ammonium carbonate to an excess of the acid. The ammonium salt is then heated to give the amide

Therefore, butanoic acid is converted to propanamide by first converting it to propanoic acid, then ammonium propanoate and then finally propanamide by heating.

In conclusion, carboxylic acids are converted to amides in two steps.

Natural gas is a mixture of many substances, primarily CH₄, C₂H₆, C3H8, and C4₄H₁₀. assuming that the total pressure of the gase
olchik [2.2K]

Answer:

A. The partial pressure for CH4 = 0.0925atm

B. The partial pressure for C2H6 = 0.925atm

C. The partial pressure for C3H8 = 0.346atm

D. The partial pressure for C4H10 = 0.115atm

Explanation:

Total pressure = 1.48atm

Total mole = 0.4+4+1.5+0.5=6.4

A. Mole fraction of CH4 = 0.4/6.4 = 0.0625

The partial pressure for CH4 = 0.0625 x 1.48 = 0.0925atm

B. Mole fraction of C2H6 = 4/6.4 = 0.625

The partial pressure for C2H6 = 0.625 x 1.48 = 0.925atm

C. Mole fraction of C3H8 = 1.5/6.4 = 0.234

The partial pressure for C3H8 = 0.234 x 1.48 = 0.346atm

D. Mole fraction of C4H10 = 0.5/6.4 = 0.078

The partial pressure for C4H10 = 0.078 x 1.48 = 0.115atm
