Answer: The concentration of 
will be 
after 416 seconds have passed.
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant = 
t = age of sample = ?
a = let initial amount of the reactant = 
a - x = amount left after decay process =
The concentration of will be after 416 seconds have passed.
Answer:
The volume of water vapor increases.
Explanation:
Pressure, concentration, and temperature all affect the equilibrium position of chemical reactions in a closed system such as this one. Increasing HCl increases the pressure in the system. It favors the forward's reaction because this favors a reduced overall pressure in the system. The products have a combined 3 moles of gases while the reactants have a combined 5 moles of gases.
For 1 mole of any substance, there are 6.02214086 × 10^<span>23 particles (atoms, molecules, ions, etc. depending on the substance)
So, for 1 mole of water, there are </span>6.02214086 × 10^23 water particles, and so on
So, in 1 mole of Lithium, there are 6.02214086 × 10^23 Lithium atoms
