Answer:
N equals to 749 newborn insects.
Explanation:
We have the following to calculate the population of newborn insects.
N = rl - bl2
In this equation we need to replace the values we know that are:
l = 500
r = 1.5
b = 0.0015
Whn we replace the values we have:
N = (1.5)(500) - (0.0015)(500)(2) <em>Now we just do the operations</em>
N = 750 - (0.0015)(1000)
N = 750 - 1.5
N = 748.5 <em>When we roung the nearest whole number we get</em>
N = 749
There were 749 new born insects that are represented by N.

<span>In order to figure out the number of atoms that are present in 2.0 mol of an element, you would multiply Avogadro's number of atoms per mole by 2.0 mole. Avogadro’s is the number of units in one mole of a substance equal to 6.022140857 × 1023.</span>
Answer:
Part 1: 2KNO3 → 2KNO2 + O2 is the balanced equation.
Part 2: The conversation of mass that demonstrates that there is no detectable change in the total quantity of matter present in the
Explanation:
Part 1: To balance a chemical equation, the number of atoms in the reactants and the products must be equal. So, the coefficient 2 added before KNO3 and KNO2 to balance the equation.
2KNO3 → 2KNO2 + O2
Part 2:
This chemical reaction demonstrates the conversation of mass that demonstrates that there is no detectable change in the total quantity of matter present when chemical change occurs (matter converts from one type to another) or physical change occurs (changes among solid, liquid, or gaseous states).
This is clear in the balanced equation.
