Answer: The final volume
is 263.09 ml
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,

where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:

Putting values in above equation, we get:

Thus final volume
is 263.09 ml
Answer:
nitrogen
Explanation:
The stoichiometry of the reaction says that
and
react 3:1 to form 2 moles of
, so, if you have 3,5 moles of H, which is equal to 1,75 moles of
, and 5 moles of N, which are equal to 2,5 moles of
. only
=0.583 moles of
, will react, leaving <em>1.917 moles of </em>
<em>unreacted</em>, and forming 0.583*2=1.166 moles of 
Answer:
320 mmol
Explanation:
405.0 mL * 1L/1000 mL = 0.4050 L
0.79 M = 0.79 mol/L
0.79 mol/L * 0.4050 L=0.32 mol
0.32 mol * 10^3 mmol/1 mol = 320 mmol
Answer: The last layer
Explanation: If nothing has affected the layers we can answer this accordingly to relative dating. The older rocks should be on the bottom while the younger rocks should be on the top.
Answer:
The solutions of hydrobromic acid and of chloric acid are the most electrically conductive.
Explanation:
The electrical conductivity of a solution is determined by the concentration of ions in the solution. The acids listed react with water to form ions. In the case of hydrobromic acid, for example, the reaction is as follows:
HBr + H2O >> H3O(+) + Br(-)
Hydrobromic acid and chloric acid are strong acids, meaning the reaction is considered to proceed at 100%. Acetic acid, however, is a weak acid and the reaction with water does not go to completion, so there are less ionic species in the solution of acetic acid, which makes it less electrically conductive.
