Answer:

6. false.  

chemical energy to heat and mechanical. Mechanical that runs the factory in the photo, and Heat energy that rises up in the atmosphere to join the other carbon

molecules in the air. 7. True. The arrow letter A is the transfer of solar power

from the sun, to a chemical reaction to produce food for the plant, which is

called photosynthesis. The leaves in the plant has chlorophyll that absorbs light

energy and transforms it to food.8. The answer would be letter C and F. C because It is

during the burning of the fossil fuels that the carbon dioxide is release into

the atmosphere. When burning the fossil fuels the carbon that was inside the

fossils is released. This also happens with diesel and other forms of natural

gas. While, F is because plant

respiration releases some of the carbon remains of the photosynthesis. While

plants do absorb carbon dioxide, part of their end product also includes reformed

carbon dioxide. Most of the other processes in the phot uses carbon or absorbs

carbon dioxide to aid their sustenance.9. A carbon cycle for living things would be A or B to F

wherein the plants absorb carbon dioxide to aid their production of food, and

then releasing carbon dioxide again as a by product of their food production.

This also happen to aquatic plants.An example of a non-living carbon cycle would be, D or E to

C. This would be the absorption of the carbon on our sea waters or to our soil,

this then gets trapped in there until it is release like through the forms of

fossil fuel burning.10. The law of conservation of mass and energy states that

matter can neither be created nor destroyed, this is very much evident in the

carbon cycle. Because the carbon from the light energy from the sun, or in our

atmosphere, ends up back to our atmosphere just to continue its cycle. The fact

that the carbon cycle is a cycle not just a linear equation proves that energy

can neither be created nor destroyed.

Q2.  0.254 g of KHP (204 g/mol) titrated against 20.0 mL of unknown NaOH (40.0 g/mol) solution to get the end point of phenolpht
Vera_Pavlovna [14]

Answer:

<u>Mass concentration (g/L) </u><u><em>= 2.49g/L.</em></u>

Explanation:

No. of moles = \frac{mass}{molar mass}

= \frac{0.254}{204} = 0.001245 moles

Concentration of KHP (C1) in litres = n/v

= \frac{0.001245}{0.02} = 0.062 mol/L

We know that:

C_{1} V_{1} = C_{2} V_{2}

where c1v1 and c2v2 are the products of concentration and volumes of KHP and NaOH respectively.

Since mole ratio is 1 : 1.

1 mole of NaOH - 40g

0.001245 mole of NaOH = 40 × 0.001245 = 0.0498g

⇒0.0498g of NaOH was used during the titration

<u><em>∴Mass concentration (g/L) = 0.0498g ÷ 0.02L</em></u>

<u><em>= 2.49g/L.</em></u>

Duncan takes a break from studying and goes to the gym to swim laps If swimming burns amount of time ? 85 * 10 ^ 5 cal per hour
Volgvan

When 6.85×10⁵ cal is converted to kilojoules, the result obtained is 2866.04 KJ

<h3>Data obtained from the question </h3>
  • Energy (cal) = 6.85×10⁵ cal
  • Energy (KJ) =?

<h3>Conversion scale </h3>

1 cal = 0.004184 KJ

<h3>How to convert 6.85×10⁵ cal to kilojoules</h3>

1 cal = 0.004184 KJ

Therefore,

6.85×10⁵ cal = 6.85×10⁵ × 0.004184

6.85×10⁵ cal = 2866.04 KJ

Thus, 6.85×10⁵ cal is equivalent to 2866.04 KJ
