Answer:
10%
Explanation:
The percent by volume of acetone is given by the following formula:
% v/v = Volume of acetone / Total Volume * 100%
Now we <u>calculate the total volume of the solution</u>:
Total Volume = Volume of Acetone + Volume of Water
Total Volume = 50 mL + 450 mL = 500 mL
Then we <u>calculate the percent by volume:</u>
% v/v = 50 mL / 500 mL * 100 % = 10%
The general equation is
<span> 2AsF3 + 3CCl4 -----------> 2AsCl3 + 3CCl2F2
2mol </span><span> 3mol</span><span>
n mol ------------------------------------------------> ?
n (</span>AsF3) =m/M= 1.13mol
so, n/2 = x/3 implies x = 3<span>n/2 = 3*1.13 / 2= 1.69 mol it is near 1.7
the answer is </span><span>e]1.705 mol</span>
Answer:
43.7mol
Explanation:
Above is dimensional analysis method. Write what you are trying to find with the question mark and write your given info on the other side of the equal sign. Follow the units and pay attention to them cancelling out. You should have your answer unit by the end.
the 180g came from the table with masses times the chemical formula all added together. Below is exact formula.
hydrogen mass(hydrogen amount) + carbon mass(carbon amount) + oxygen mass(oxygen amount)
1g(8)+12g(9)+16g(4)=180g
180g is 1 mole of
Answer:
Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There's a catch, though: absolute zero is impossible to reach.
Explanation:
Of the above options you've given, the only nuclear reaction is fission.
fermentation is when organic matericals go bad and delope mold for exg,
reduction is when atoms of elements have their oxidation states changed (exg rusting)
deposition is when molecules set out in any sort of solution.
