Answer:

The number and the kinds of atoms in the compound

Explanation:

A chemical formula of a compound contains symbols o the atoms of the elements present in the compound as well as the number of atoms of each element in the form of subscripts.
Therefore it helps us to know the elements in a compound and the number of atoms in the compounds.

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)

For the first option, b = 12, i = 0, d = 12, e = 12

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

For the second option: b = 13, i = 0, d = 3, e = 16

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

For the third option: b = 12, i = 20, d = 0, e = 8

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

For the last option: b = 0, i = 14, d = 4, e = 10

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

Hence, the last option is the correct option.

Sucrose is very soluble in water. at 25◦c, 211.4 grams of sucrose will dissolve in 100 g of water. given that the density of the

stiv31 [10]

Molarity of solution is mathematically expressed as,
M = $\frac{x\text{weight of solute(g)}}{\text{Molecular weight X Volume of solution(l)}}$

We know that volume = mass/density
Given: mass of solution = 100 g, Density = 1.34 g/ml
∴ volume = 100/1.34 = 88.49 ml = 0.08849 l

Also, we know that molecular weight of sucrose = 342.3 g/mol
∴M = $\frac{x\text{211.4}}{\text{342.3 X 0.08849}}$
= 6.979 M

Thus, molarity of solution is 6.979 M
