Answer:

Fluorine

Explanation:

Data obtained from the question include:

The isotope of fluorine has:

Proton = 9

Neutron = 10

The atomic number is the proton number of the atom.

Therefore, the atomic number = 9

Mass number = proton + Neutron

Mass number = 9 + 10

Mass number = 19

Now comparing the above with the fluorine atom in the periodic table. We'll discover that the isotope is actually fluorine atom.

Therefore, the name of the isotope is fluorine

!! ANSWER QUICK !!
kari74 [83]

Answer:

I can use a dichotomous key. It helps me classify objects by sorting it out with "yes" and "no" questions.

or

I can use a Punnett Square. It helps me classify what genes the offspring will receive simply by figuring out the recessive and dominant genes as well as the hetzygous and homzygous.

Now give an example of which ever chart you choose by drawing it if that is required. For the Punnett Square label each of the squares Top right Hetzygous, top left dominant, bottom left recessive, bot-tom right homzygous. And for the dichotomous key put a 5-7 length branch showing the animals that have fur, can breathe under water, what cannot or doesn't have those traits. or something similar

Hopefully this helps :)

18. What is the percent by mass sugar of a solution made by dissolving 12.45 grams of sugar in 100 grams of water?
Fantom [35]

The percent by mass sugar of a solution : 11.07%

<h3>Further explanation</h3>

Given

mass of sugar = 12.45 g

mass of water = 100 g

Required

The percent by mass

Solution

Mass of solution :

\tt mass~sugar+mass~water=12.45+100=112.45~g

Percent mass of sugar :

\tt \%mass=\dfrac{mass~sugar}{mass~solution}\times 100\%\\\\\%mass=\dfrac{12.45}{112.45}\times 100\%=11.07\%
