Answer:
It will take
to exhaust the supply
Explanation:
We have to apply unitary method to solve this problem.
Divide total petroleum reserve by petroleum consumption in each year to calculate estimated time.
Presently,
joules of petroleum are being consumed per year.
Hence, applying unitary method,
joules of petroleum can be consumed in 
Answer:
325 cm is equivalent to 3250 mm.
Explanation:
In this case, we need to convert 325 cm of copper wire into mm. The conversion from cm to mm is given below :
1 cm = 10 mm
To convert 325 cm to mm, we will use unitary method.
325 cm = 325 × 10 mm
325 cm = 3250 mm
So, 325 cm is equivalent to 3250 mm.
Answer:
The liquid boils.
Explanation:
Vapor pressure is simply defined as the pressure exerted on a substance (solid/liquid) by the vapor of the substance collected just at the top of the surface of the substance. In concise words, it is the pressure of Vapor that is in contact with its solid or liquid state.
For a liquid, it is the pressure of the Vapor gathering at the top of the surface of the liquid.
When this Vapor pressure matches the external pressure, the temperature stays constant and the molecules of the liquid all through the liquid can gain enough energy, rise to the surface of the liquid and break free in gaseous form; thereby, boiling.
The definition of boiling point basically explains that it is the point at which temperature stays constant, and the vapour pressure of the liquid matches the atmospheric/external pressure around the liquid and its liquid molecules change into vapor.
This is why liquids boil faster at higher altitudes; the atmospheric pressure at higher altitudes is reduced, hence, the temperature at which liquid boils at this high altitude is normally lower than its known boiling point temperature.
It is also why food cooks to a temperature higher than the boiling point of water in a pressure cooker/pot. The added pressure ensures that the cooking water boils at temperatures higher than its boiling point; thereby exposing the cooking ingredients to a higher temperature, leading to faster cooking.
Hence, it is obvious why boiling is the answer to this question.
Answer:
4
Step-by-step explanation:
The reactions are:
Glycolysis: 1 glucose ⟶ 2 pyruvate
Link reaction: 2 × [1 pyruvate ⟶ 1 acetyl CoA]
Citric acid cycle: 2 × [1 AcetylCoA ⟶ 2 CO₂]
Now, add the reactions, cancelling species that occur on both sides of the reaction arrow,
1 glucose ⟶ <u>2 pyruvate
</u>
<u>2 pyruvate</u> ⟶ <u>2 acetyl CoA
</u>
<u>2 AcetylCoA </u>⟶ 4 CO₂
<em>Overall</em> : 1 glucose ⟶ 4 CO₂
For each mole of glucose, four molecules of CO₂ are released in the citric acid cycle.
Answer:
The limiting reactant is salicylic acid.
Explanation:
From the equation of reaction,
1 mole of acetic anhydride (C4H6O3) (102g) reacts with 2 moles of salicylic acid (C7H6O3) (276 g)
80 g of acetic anhydride would react with (80×276/102) = 216.5 g of salicylic acid
216.5 grams of salicylic acid that is required to react with 80 grams of acetic anhydride.
The available mass of salicylic acid is 70 grams which makes salicylic acid the limiting reactant.
