Answer: A.They often use up resources that other organisms need.

Explanation:

A nonnative species is the one which is either intentionally or accidentally introduced into a new habitat. This species is capable of competing with the native species for resources like water, food and mates. This may result in the decline of the native species due to mortality of the members of the native species, migration and extinction. Therefore, the biodiversity of the region will decrease.

IgorC [24]

Answer:

The answers to your questions are given below

Explanation:

The following data were obtained from the question:

CH3COOH → CH3C00^- + H^+

Equilibrium constant, Ka = 1.8 x 10^-5

AgCl → Ag^+ + Cl^-

Equilibrium constant, Ksp = 1.6 x 10^-10

Al(OH)3 → Al^3+ + 3OH^-

Equilibrium constant, Ksp = 3.7 x 10^-15

A+B → C

Equilibrium constant, K = 4.9 x 10^3

When the value of the equilibrium constant is grater than 1, it shows that the concentration of product is higher than that of the reactant and it implies that the forward reaction is favored.

When the value of the equilibrium constant is 1, it shows that the the concentration of the product and reactant are the same. Therefore neither the forward nor the reverse reaction is favored.

When the value of the equilibrium constant is lesser than 1, it shows that the concentration of the reactant is higher than the concentration of the product. Therefore, the reversed reaction is favored.

Now, we shall the question given above as follow:

A. CH3COOH → CH3C00^- + H^+

Equilibrium constant, Ka = 1.8 x 10^-5

Since the value of the equilibrium constant is lesser than 1, it means that the reverse reaction is favored.

B. AgCl → Ag^+ + Cl^-

Equilibrium constant, Ksp = 1.6 x 10^-10

Since the value of the equilibrium constant is lesser than 1, it means that the reverse reaction is favored.

C. Al(OH)3 → Al^3+ + 3OH^-

Equilibrium constant, Ksp = 3.7 x 10^-15

Since the value of the equilibrium constant is lesser than 1, it means that the reverse reaction is favored.

D. A+B → C

Equilibrium constant, K = 4.9 x 10^3

Since the value of the equilibrium constant is greater than 1, it means that the forward reaction is favored.

2. Calculate how many moles of H2 would be produced if 0.250 mol of Fe reacts completely. (1 mark)
den301095 [7]

Hey there!:

Balanced Equation , for the reaction:

3 H₂SO₄(aq) + 2 Fe(s) → Fe₂(SO₄)₃(aq) + 3 H₂(g)

2 moles Fe ---------------------------------- 3 moles H₂

0.250 moles Fe ---------------------------- ( moles H₂ ) ??

____________________________________________

moles H₂ = 0.250 × 3 / 2

moles H₂ = 0.75 / 2

moles = 0.375 moles of H₂

Hope this helps!

Name one alternative pathway to glycolysis: _______________________
NemiM [27]

solution:

The Enter–Doudoroff pathway describes an alternate series of reactions that catabolize glucose to pyruvate using a set of enzymes different from those used in either glycolysis or the pentose phosphate pathway. .... Most bacteria use glycolysis and the pentose phosphate pathway.

Which of the fallowing elements is the most reactive?
Alexxx [7]
Which elements are most reactive?

The alkali metals, found in group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements.

Fluorine is the most reactive
