Answer: 125
Explanation: volume is l x w x h and if its a cube then length, width and the height will be the same so its just 5 x 5 x 5
Answer:
AgNO3
Explanation:
Considering the equation:
2 AgNO3(aq) + CuCl2(aq) ––> Cu(NO3)2(aq) + 2 AgCl(s)
2 moles of AgNO3 reacted with 1 mole of CuCl2
divide the moles by two
1 mole of AgNO3 will react with 0.5 mole of CuCl2
then
0.5 mole AgNO3 will react with 0.25 mole of CuCl2 and limiting reagent is the reagent that is consumed when the reaction is completed.
Going by the calculation above the limiting reagent is AgNO3
<u>Answer:</u> The solubility of ethylene gas in water is
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant =
= molar solubility of ethylene gas = ?
= partial pressure of ethylene gas = 0.684 atm
Putting values in above equation, we get:
Converting this into grams per liter, by multiplying with the molar mass of ethylene:
Molar mass of ethylene gas = 28 g/mol
So,
Hence, the solubility of ethylene gas in water is
Number of moles = 2.12 mol C3H8.
1 mol C3H8 = 6.02 × 1023 molecules C3H8.
<span>1 molecule C3H8 = </span>11 atoms.
(3 carbon atoms<span> and 8 hydrogen atoms)</span>
