1 can of soda has 12 ounces * 2.01 mg/oz = 24.12 mg of caffeine.
1 gram = 1000 mg
10 grams x 1000 mg = 10,000 mg
Divide total mg by mg per can:
10,000 / 24.12 = 414.59 cans
Round to 415 cans
Answer:
B. A reaction at equilibrium will respond to balance a change.
Explanation:
The Le Chatelier's principle states that a reaction will respond to balance a change. This is true for a reaction in chemical equilibrium.
Le Chatelier's principle sates that "if any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
- It explains the effect of applying stress on any system in equilibrium.
- The changing conditions are usually concentration, temperature and pressure.
- If the stress due to any of them is applied to a system in equilibrium, the equilibrium will respond in the directions which counteracts the effect of the stress.
Answer: increase pressure and decrease temperature.
Explanation:
Increasing pressure uses force to make the gas molecules come closer together. (Decreasing pressure allows the molecules to spread out) Decreasing temperature will also cause the molecules of gas to come together closer. (Heat excites molecules causing them to spread out and therefore expand)
Answer:
C2H4Cl2
Explanation:
Firstly, we know that the compound contains only three elements. These are carbon, hydrogen and oxygen. We have the percentage compositions of carbon and hydrogen, thus we need the one for chlorine. To get the one for chlorine, we simply subtract that of carbon and hydrogen from a total of 100%.
Hence percentage composition of chlorine = 100 - 24.27 - 4.07 = 71.66%
Now, we divide the percentage compositions by the atomic masses. The atomic masses of carbon, hydrogen and chlorine are 12, 35.5 and 1 respectively. We go on to the divisions as follows.
C = 24.27/12 = 2.0225
H = 4.07/1 = 4.07
Cl = 71.66/35.5 = 2.02
We then go on to divide each by the smallest which is 2.02
C = 2.0225/2.02 = 1
H = 4.07/2.02 = 2
Cl = 2.02/2.02 = 1
Hence the empirical formula is CH2Cl
Now, since the molecular mass is 98.95, we need to calculate the molecular formula
Hence, [CH2Cl]n = 98.95
[12 + 2(1) + 35.5]n = 98.95
[12 + 2 + 35.5]n = 98.95
49.5n = 98.95
n = 98.95/49.5 = 2
The molecular formula is thus [CH2Cl]2 = C2H4Cl2
The type of carbon fixation stores carbon dioxide in acid form is CAM i.e. crassulacean acid metabolism.
<h3>What are CAM?</h3>
CAM stands for crassulacean acid metabolism in this process photosynsthesis is occured at day time but the exchange of gases takes place at night itself only.
In this carbon fixation process, carbon dioxide is stored in the form of organic acid malic acid and losses carbon dioxide at the night time and by doing this it helps in the storage of water.
Hence option (C) is correct.
