Answer:

Since the alligator population decreased, this means there are less predators for the gar. Less predators for the gar mean the gar population will increase. More gar also means more competition for the diving duck in terms of animals that eat crabs, and thus the diving duck population will also decrease.

If U-235 decays into Cs-135 and 4 neutrons, what other nuclide will be produced?

dmitriy555 [2]

If U-235 decays into Cs-135 and 4 neutrons, the other nuclide that will be produced is Rb-96 (option D).

<h3>What is radioactive decay?</h3>

A radioactive decay is the process by which an unstable large nuclei emit subatomic particles and disintegrate into one or more smaller nuclei.

According to this question, a radioactive material Uranium- 235 undergoes radioactive decay into Cs- 135 and 4 neutrons (1/0n).

This means that the mass of the products we have is 135 + 4 = 139.

The mass of the nuclide left must be 235 - 139 = 96, hence, the other nuclide that will be produced is Rb-96.

Which scenario would result in a population growth of zero? Use this formula: population growth = (birth rate + immigration) – (

swat32

Answer:

12 individuals are born 10 individuals emigrate, 4 individuals die, 14 individuals immigrate, 0 individuals are born

Explanation:

From the formula:

Population growth = (birth rate + immigration) – (death rate + emigration)

= (b + i) - (d + e)

<em>For the first option, b = 12, i = 0, d = 12, e = 12</em>

population growth = (12+0) - (12+12) = -12

<em>For the second option: b = 13, i = 0, d = 3, e = 16</em>

population growth = (13+0) - (3+16) = -6

<em>For the third option: b = 12, i = 20, d = 0, e = 8</em>

population growth = (12+20) - (0+8) = 24

<em>For the last option: b = 0, i = 14, d = 4, e = 10</em>

population growth = (0+14) - (4+10) = 0

Hence, the last option is the correct option.

What is the molar concentration of hydronium ions in a sample of a soft drink that has a ph of 4?

hammer [34]

[ $H^{+}$ ] value of soft drink is 0.0001mol/l when given pH is 4.

Given:

pH = 4

Needs to find: [ $H^{+}$ ]

Formula to find: pH=−log $_{10}$ [ $H^{+}$ ]

We can put the values of pH in above formula as,

pH=−log $_{10}$ [ $H^{+}$ ]

4 =−log $_{10}$ [ $H^{+}$ ]

To calculate hydonium ion concentration, formula is as follows;

[ $H^{+}$ ] = $10^{-pH}$

[ $H^{+}$ ] = $10^{-4}$ = 0.0001mol/l

[ $H^{+}$ ] value of soft drink is 0.0001mol/l
