A certain drug is made from only two ingredients: compound A and compound B. There are 5 milliliters of compound A used for every 4 milliliters of compound B. If a chemist uses 255 milliliters of compound A, how many milliliters of the drug will be made?

----------------------------------

4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.

---

Solve for "x":

If amount of compound A is 4x = 255

x = 255/4

------------------------------

Then amount of compound B is 5x = 5(255/4) = 318.75 ml

What is the percentage of calories from fat for a piece of pie that contains 300 calories and 12 grams of fat?
kupik [55]
Percentage of calories = ?
Fat = 12 grams
Total calories  = 300
1 gram fat = 9 calories
to calculate calories convert gram into calories and then divide by total calories.
No. of calories = (12 x 9) / (300) = 0.36
So, percentage of calories = 0.36 x 100 = 36%

Toussaint Louverture International Airport:

If we talk about the focus point of the Haiti earthquake  that hit the Haiti  on 12th january, 2010, then it was around 6 miles away from Toussaint Louverture International Airport.

Since the center was so near to airport that is why airport suffered from alot of damage. The control tower of the airport was almost completely destroyed due to which any radio communication became impossible. There was heavy power outrage due to damage caused to the power lines and due to this lightening system of the airport was completely shutdown. was damaged. However,  the taxiways, runways and apron parts of the airport were operational at even that time of crisis.

Due to immense amount of damaged caused to Toussaint Louverture International Airport, all the relief bringing planes were diverted to other airports of the city.

The reconstruction and rehabilitation of the airport was started during 2010. It included the restoration  and renovation of arrival and departure halls that were previously completely devastated. The renovation os falls included  installation 16 new stations and three large baggage carousels and  in the immigration room, There was also a significant explansion in the custom rooms.

However, the damage caused to Toussaint Louverture International Airport dur to 2010 Haiti earthquake is still considered as the destruction of major landmark due to earthquake.

Hope it helps!

How many CO2 molecules are produced when three glucose molecules undergo cellular respiration? Explan ​
Svetlanka [38]

Answer:

<u>18 molecules of </u>CO_{2}<u />

Explanation:

In heterotrophic nutrition, organisms ingest or absorb food made by autotrophs to obtain energy. Planta and other photosynthesizing organisms make sugars via photosynthesis, in a form of (partly) light-dependent biosynthesis.

In mitochondria, they break down sugars through aerobic respiration. For the sugar glucose, this results in the production of carbon dioxide and water along with energy in the form of ATP or adenosine triphosphate.  

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen →  carbon dioxide+ water+ energy

For 3 molecules of glucose, multiply the number of reactants and products...

(C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP ) x 3

Thus...

3 C6H12O6+ 18 O2 → 18 CO2 + 18 H2O + ≅114 ATP

Where does pyruvate as intermediate take place in photosynthesis? plz explain also thanks
mr Goodwill [35]

Answer:

Pyruvate take place after the process of glycolysis.

Explanation:

Pyruvate as intermediate take place in the process of photosynthesis after glycolysis process. One glucose molecule is converted into two molecules of pyruvate. This pyruvate molecule then converted into acetyl CoA, which is a two-carbon molecule. A molecule of coenzyme A is a very important reactant for this reaction, which produces a molecule of carbon dioxide and reduces a NAD+ to NADH.
