How do the mass and height of an object affect the gravitational potential energy?
marin [14]

Answer:

B. mass and height have the same effect on gravitational potential energy.

Explanation:

Both mass and height have the same effect on the gravitational potential energy of body.

Gravitational potential energy is the energy of a body due to that of another body. It usually the energy at rest in a body.

It is mathematically expressed as;

 G.P.E  = m x g x h

m is the mass

g is the acceleration due to gravity

h is the height

We see that both the height and mass are directly proportional to the gravitational potential energy and as such, they have the same effect.

How many potassium atoms are in 250.0 grams of potassium?
loris [4]

Hi!


The correct option would be 3.85x10^(24)


To find the number of atoms in 250g of potassium, we need to first calculate the number of atoms in


1 mole of Potassium = 39g which contains 6.022x10^(23) atoms of K

<em>(Avogadro's constant value for the amount of molecules/atoms in one mole of any substance)</em>

<em>Solution</em>

So as 39g of Potassium contains 6.022x10^(23) K atoms

1g of Potassium would contain 6.022x10^(23) / 39 = 1.544 x10^(22) atoms

So 250g of Potassium would contain 1.544x10^(22) x 250 = 3.86x10^(24) atoms

Chrysanthenone is an unsaturated ketone. If Chrysanthenone has M+ = 150 and contains 2 double bond(s) and 2 ring(s); what is its
snow_lady [41]

Answer:

the Molecular formula will be; C10H14O

Explanation:

Given the data in the question;

Chrysanthenone is an unsaturated ketone,

it has M+ = 150 and contains 2 double bond(s) and 2 ring(s).

molecular formula = ?

we know that ketone contain 1 oxygen and mass of oxygen is 16

so mass of the C and H remaining will be;

⇒ 150 - 16 = 134

Now we determine the number of C atoms;

⇒ 134 / 13 = 10

hydrocarbon with 10 hydrogen atom have CnH2n+2 means

⇒ ( 10 × 2 ) +2 = 22 hydrogens

But then we have 3 unsaturation meaning 6 hydrogens less and also we have ring meaning 2 more hydrogens

⇒ 22 - 6 - 2 = 14

Hence the Molecular formula will be; C10H14O
