Answer:
Calculate the volume of dry gas at STP. 28). A 255-mL sample of nitrogen was collected over water at 21oC at a pressure of 745 mm
Explanation:
Answer:

Explanation:
we have

Solve for x
That means----> Isolate the variable x
Applying the distributive property both sides

Remember that


Combine like terms left side

Adds 7x both sides


Adds 4 both sides


Divide by 9 both sides

=>. the function of greenhouse gases are
=>. it captures the heat comming out from the
sun
=>. by capturing the heat it makes our earth
warm
=> if excess of heat will traped by them then
our earth become more warm and this leads
to increase in temperature
=> when the overall temperature will increase
then the ice sheets on pole will melts
and this leads to increase in sea level
=> then the land near water will sinks in water
Answer:
The correct statements are :b, c , d, and e.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
K is the constant of a certain reaction when it is in equilibrium, while Q is the equilibrium quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
, reaction will move in forward direction and concentration of products will increase.
, reaction will move in backward direction and concentration of reactant will increase.
reaction is at equilibrium.
