Answer:

Population of duck and frog will change with the change

Explanation:

The complete question is

Scientists are studying animals in a large lake area. In this lake area, both owls and raccoons eat ducks, and ducks eat frogs. The data shows that recently the size of the raccoon population decreased. How will the decrease in the raccoon population affect the other populations? Be sure to explain whether the owl population, the duck population, and the frog population will change, and why.

  1. Owl population will change
  2. Duck population will change
  3. Frog population will change

Solution

Raccoon eat duck and duck eat frog. Now if the population of Raccoon decreases then the number of predators of duck will decrease thereby increasing the population of duck.

The higher will be the number of ducks, the more frogs they will consume thereby decreasing the population of frogs

Hence both the population of duck and frog will change with the change

NH,F+ _AICI,<br>__NH,CI + __A!F,​
mart [117]

Explanation:

                          NH₄F+     AICI₃,    →   NH₄CI +   AlF₃

   NH,F: in ionic form

           NH₄⁺ + F⁻   =    NH₄F

   AICI in ionic form:

         Al³⁺ + Cl⁻   = AlCl₃

   NH Cl in ionic form:

          NH₄⁺ + Cl⁻ = NH₄Cl

    Al F in ionic form:

         Al³⁺ + F⁻   =  AlF₃

                     NH₄F+     AICI₃,    →   NH₄CI +   AlF₃

Now we have to balance the equation with respect to the atoms:

           aNH₄F+     bAICI₃,    →   cNH₄CI +   dAlF₃

  for N: a = c

        H: 4a = 4c

        F:  a = 3d

        Cl: 3b = c

   let a = 1

        c = 1

         b = \frac{1}{3}

        d = \frac{1}{3}

Therefore we can imply that:

     a = 3, b = 1 , c = 3 and d = 1 if we multiply through by 3

          3NH₄F+     AICI₃,    →   3NH₄CI +   AlF₃

5.01 moles of magnesium phosphate contain how many atoms of phosphorus?
VMariaS [17]

Answer:

Explanation:

Deal with 1 mole first.

The chemical formula of Magnesium Phosphate is

Mg3(PO4)2

The 2 tells you that there are 2 mols of Phosphorus in the chemical.

1 mol of anything is 6.02 * 10^23 (in this case) atoms.

2 mols of anything is 12.04 * 10^23 atoms

2 moles of anything is 1.204 * 10^24 (the 2 answers are the same. This one is more correct in scientific notation.)

Now we come to the 5.01. Where does that go?

5.01 * Mg3(PO4)2

So multiply 1.204 * 10^24 by 5.01 When you do, you get

7.26 * 10^24 atoms
