Answer:

The fox who shed their heavy coat in the summer.

Explanation:

If a fox has the ability to shed its coat in the summer, it will have no difficulties adapting to new temperatures even during winter. However, the heavy-coated one will.

Answer:

The identity of an atom is determined my the number of <u>protons</u>. This is the <u>atomic number</u>.

The particle(s) found inside the nucleus are called <u>protons and neutrons</u>. Their combined mass is referred to as <u>the mass number</u>.

Isotopes have the same number of <u>protons</u>, but different number of <u>neutrons</u>.

A sample of a compound is determined to have 1.17 g of carbon and 0.287 g of hydrogen. what is the correct representation of the
yarga [219]

CH3 is the empirical formula for the compound.

A sample of a compound is determined to have 1.17g of Carbon and 0.287 g of hydrogen.

The number of atom or moles in the compound is

1.17 g C X  1 mol of C / 12.011 g C = 0.097411 mol of C.

0.287 g H x 1 mol of  H / 1 g H = 0.28474 mol H.

This compound contains 0.097411 mol of carbon and 0.28474 mol of Hydrogen.

So we can represent the compound with the formula C0.974H0.284.

Subscripts in formulas can be made into whole numbers by multiplying the smaller subscript by the larger subscript.

we can divide 0.284 by 0.0974.

0.284 / 0.0974 = 3.

So here, Carbon is one and hydrogen is 3.

We can write the above formula as a CH3.

Hence the empirical formula for the sample compound is CH3.

What is the mole fraction?​
sleet_krkn [62]
Mole fraction is a unit of concentration, defined to be equal to the number of moles of a component divided by the total number of moles of a solution. Because it is a ratio, mole fraction is a unitless expression. The mole fraction of all components of a solution, when added together, will equal 1.

Explain how the concentration of hydronium ions and hydroxide ions are related to pH.
Dominik [7]
Hello!

The concentration of hydronium ions is related to pH by the following simple equation:

pH=-log[H_3O^{+}]

From this equation, you can see that as the hydronium concentration is higher, the pH will be lower.

The concentration of the OH⁻ ions is related to the pH by the following set of equations

pOH=-log[OH^{-}] \\ pH=14-pOH

You can see that as the concentration of OH⁻ is higher, the pOH is lower and thus the pH is higher. 

When the pH of the solution is less than 7, the solution is acidic.

When the pH of the solution is higher than 7, the solution is basic.

Have a nice day!
