Answer:
The increase of prey
Explanation:
Without predators in the ecosysten prey population would increase
Answer:
According to the modern periodic law, the properties of the elements and their compounds are a periodic function of their atomic numbers. Thus, in the modern periodic table, atomic number forms the basis of the classification of elements;The modern table is called 'long form' of the periodic table.

<u>Answer:</u> The fugacity coefficient of a gaseous species is 1.25
<u>Explanation:</u>
Fugacity coefficient is defined as the ratio of fugacity and the partial pressure of the gas. It is expressed as 
Mathematically,
Partial pressure of the gas is expressed as:
Putting this expression is above equation, we get:
where,
= fugacity coefficient of the gas
= fugacity of the gas = 25 psia
= mole fraction of the gas = 0.4
P = total pressure = 50 psia
Putting values in above equation, we get:
Hence, the fugacity coefficient of a gaseous species is 1.25
Answer:
Explanation:
1. Select all the statements about the nucleus of the atom that are correct:
Group of answer choices
B. It contains Protons
D. It has a Positive Charge
E. It contains Neutrons
2. An atom of an element with atomic number 50 and mass number 120 contains:
Group of answer choices
B. 50 protons, 50 electrons, and 70 neutrons
3. Which of these statements is false?
Group of answer choices
D. Electrons have the same mass as a proton but have the opposite charge.
1. Determine if the ionic substances can break apart into ions.
- e.g. CaCO3 isn't very soluble, do it can't dissolve and dissociate. If it can't pop apart, no ions.
2. Swap the partners for all the other ions that you can get from step 1. You can skip pairings with the same charge - a + can't get close to another + to react.
3. Use solubility, acid/base, and redox rules to see if anything will happen with the ions in solution.<span />
