B: The total thermal energy is greater in a large body of water than one much smaller

Explanation:

A large lake filled filled with cool water will have more thermal energy than smaller pond filled with warmer water because the total thermal energy is greater in a large body of water than one that is much smaller.

Thermal energy is a form of kinetic energy usually due to transfer of heat energy.

Amount of heat energy is dependent on the differences in temperature, mass and specific heat capacity of a body.

Both lake water will have the same specific heat capacity. Since larger body of water has more mass, it will possess more thermal energy.

What makes an atom able to form a compound? * O different number of neutron than protons O unfilled outer electron shells O same

GaryK [48]

Answer:

same number of protons as electrons

Explanation:

The addition of a neutron can make an atom radioactive. When you change the number of protons in an atom, you will change the atom from one element to a different element. ... If you change the number of electrons in an atom, you will get an ion of the element.

A car moves with an average speed of 45miles /hour. How long does the car take to travel 90miles?

storchak [24]

Averqge speed of the car = 45 miles/hr, which means,

The car travels 45 miles in 1 hr.

Using unitary method,

The car travels 45 miles in 1 hr

The car would travel 1 mile in 1/45 hrs

The car would travel 90 miles in 1/45×90 hrs

So, calculating this,

1/45×90 = 2 hrs

Vinegar is an aqueous solution of acetic acid, ch3cooh. a 5.00 ml sample of a particular vinegar requires 26.90 ml of 0.175 m na

Fed [463]

The molarity of acetic acid in the vinegar is 0.94 M

<u><em> calculation</em></u>

Step 1: write the balanced equation between CH3COOH + NaOH

that is CH3COOH + NaOH → CH3COONa + H2O

step 2 : find the moles of NaOH

moles =molarity x volume in L

volume in liters = 26.90/1000=0.0269 l

moles = 0.175 mol /L x 0.0269 L =0.0047 moles of NaOH

Step 3: use the mole ratio to find moles of CH3COOH

that is the mole ratio of CH3COOH: NaOH is 1:1 therefore the moles of CH3COOH is =0.0047 moles

Step 4: find the molarity of CH3COOH

molarity = moles/volume in liters

volume in liter = 5.00/1000 =0.005 l

molarity is therefore=0.0047 moles/ 0.005 l = 0.94 M

G identify which substitution product is expected to be favored. explain. the product with retention of configuration is expecte

ddd [48]

The substitution product that is supposed to be favoured. The product with retention of configuration is expected to predominate slightly because the leaving group blocks the nucleophile.

<h3>What is a substitution product?</h3>

A substitution product is a product that is gotten from a reaction in which a group of reactants is replaced by another group in the reaction.

Therefore, the substitution product is supposed to be favoured. The product with retention of configuration is expected to predominate slightly because the leaving group blocks the nucleophile.
