Answer: The volume of the gas in the squirrel now is 0.00532 L
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 the volume of the gas in the squirrel now is 0.00532 L
Answer:
4.73 mol NH
Explanation:
What we're doing here is calculating basic mole-mole relationships, something that you'll be doing quite a bit!
The steps to solving mole-mole problems like this are
write the balanced chemical equation for the reaction (this is given)
divide the number of moles of the given known substance (3.55) by that substance's coefficient in the chemical equation (3)
multiply that number by the coefficient of the substance you're trying to find (4)
Using simple dimensional analysis, it looks like this:
Answer:
Na2Co3 (aq) + CaCl2 (aq) ---> CaCO3 (s) + 2NaCl (aq)
