Answer: I'm thinking it should be either stay the same or decrease
Explanation: If the size is increasing then the sample should not increase but decrease or stay the same. Mainly the sample would do the opposite of what the size is doing
Answer:
200cc of 5N HCl were diluted
Explanation:n
<em>Assuming the solution was diluted to prepare a 1N HCl solution:</em>
The HCl was diluted from 5N to 1N, that is a dilution of:
5N / 1N = 5 times
As the total volume of the diluted solution is 1L = 1000mL = 1000cc the amount of the concentrated solution was:
1000cc / 5 =
<h3>200cc of 5N HCl were diluted</h3>
Answer : The number of sodium ions is equal to the number of formula units of salt.
Explanation : In the given reaction of NaCl the statement which describes it the best is that the number of sodium ions is found to be same along with the formula units in the product side.
+ 
----> NaCl.
Its clear from the equation that one mole of Na and one mole of Cl combines together to give the product, which is one mole of NaCl. The number of ions on both the sides are equal.
Answer:

Answer is: the molecular formula is C₆H₁₀.
Chemical reaction: C₆Hₓ + yO₂ → 6CO₂ + x/2H₂O.
m(H₂O) = 0.9102; mass of the water.
n(H₂O) = m(H₂O) ÷ m(H₂O)
n(H₂O) = 0,9102 g ÷ 18 g/mol
n(H₂O) = 0,0505 mol.
From chemical reaction: n(H) = 2 · n(H₂O).
n(H) = 0.101 mol.
m(CO₂) = 2.668 g; mass of carbon dioxide.
n(CO₂) = 2.668 g ÷ 44 g/mol.
n(CO₂) = 0.0606 mol; amount of the substance.
n(CO₂) = n(C) = 0.0606 mol.
n(C) : n(H) = 0.606 mol : 0.101 mol.
n(C) : n(H) = 6 : 10; proportion of carbon and hydrogen atoms in cyclohexene.
