Which statement does not describe competition for shelter?

Chemistry
1 answer:
Tema [17]3 years ago
4 0
It’s a struggle, a fight, two entities opposing each other for a desired outcome. We see the forces of competition at work in our everyday lives- feuding political parties, commercial product markets, rivaling athletics. Competition happens when two parties want the same thing, but there isn’t enough of it to go around…so they compete for it.

Calculate the molarity (m) of a solution prepared by dissolving 10.7 g nai in 0.250 l.
Lilit [14]
Molarity is defined as the number of moles of solute in 1 L of solution 
number of moles of NaI - 10.7 g / 150 g/mol = 0.0713 mol 
there are 0.0713 mol in 0.250 L
we need to find the number of NaI moles in 1 L
if 0.250 L contains - 0.0713 mol 
then 1 L contains - 0.0713 mol / 0.250 L  = 0.285 mol/L
molarity is 0.285 M

You are given the following boiling point data. Which of the liquids would you expect to have the highest vapor pressure at room
Leokris [45]

Answer:

Diethyl ether

Explanation:

vapor pressure - the pressure exerted by the gaseous molecules on the walls of the container , is called its vapor pressure.

The compound with higher boiling point , will have lower vapor pressure ,

and the compound with lower boiling point , will have higher vapor pressure.

Hence, Boiling point and vapor pressure have inverse relation.

The vapor pressure and boiling point both, depends on the inter molecular interactions , i,e, the interaction between the molecules.  

Since, the compound with stronger inter molecular interactions, will not easily convert to gas, hence will have higher boiling point between , therefore , its vapor pressure would be less.

But the compound with less inter molecular interactions , can easily vaporize to convert to gaseous state and hence will have lower boiling point, therefore, its vapor pressure would be higher .

Among all the options , diethyl ether have lowest boiling point , hence, will have highest vapor pressure , at room temperature.

H2(g) + CO2(g) + 10 kcal H2O(g) + CO(g)
EleoNora [17]

<u>Answer:</u> The equilibrium constant for the given reaction is 0.8

<u>Explanation:</u>

Equilibrium constant is defined as the ratio of concentration of the products raised to the power its stoichiometric coefficients to the concentration of reactants raised to power its stoichiometric coefficient. It is represented as K_c

For the general equation:

aA+bB\rightleftharpoons cC+dD

The equilibrium constant is represented as:

K_c=\frac{[C]^c[D]^d}{[A]^a[B]^b}

For the given chemical equation:

H_2(g)+CO_2(g)+10 kcal\rightleftharpoons H_2O(g)+CO(g)

K_c for this equation is given by:

K_c=\frac{[H_2O][CO]}{[H_2][CO_2]}

Concentration at equilibrium of

H_2=2mol/L\\H_2O=4mol/L\\CO_2=5mol/L\\CO=4mol/L

Putting values in above equation, we get:

K_c=\frac{4\times 4}{2\times 5}\\K_c=0.8

Hence, the equilibrium constant for the given chemical reaction is 0.8
