Answer:
Q = 0.50
No
Left
Explanation:
At a generic reversible equation
aA + bB ⇄ cC + dD
The reaction coefficient (Q) is the ratio of the substances concentrations:
Solids and liquid water are not considered in this calculus.
When the reaction achieves equilibrium (concentrations are constant), the Q value is named as Kc, which is the equilibrium constant of the reaction. If Q > Kc, it indicates that the concentration of the products is higher, so, the reaction must progress to the left and form more reactants; if Q < Kc, than the concentrations of the reactants, are higher, so, the reaction progress to the right.
In this case:
Q =
Q = 0.50
So, Q > Kc, the reaction is not at equilibrium and it progresses to the left.

Answer:
The number of mole represented is 2.07 moles
Explanation:
Using the formula
n = m/Mm
n - mole
m - mass
Mm- molar mass
Since the mass is given to be 213g
So lets calculate the molar mass of sodium bromide (NaBr)
The molar mass of Na = 22.99
Br = 79.904
Molar mass = 22.99+79.904
= 102.894g/mol
Using the formula n = m/Mm
n = 213g/ 102.894g/mol
n = 2.07moles
The balanced chemical reaction is:
<span>2H2+O2-->2H2O

To determine the mass of hydrogen that is needed, we need use the initial amount of oxygen and relate it to hydrogen from the reaction given. We do as follows:
192 g O2 ( 1 mol O2 / 32 g O2) ( 2 mol H2 / 1 mol O2 ) ( 2.02 g H2 / 1 mol H2 ) = 24.24 g H2
