Which of the following ions is formed when an acid is dissolved in a solution?
kiruha [24]

Answer:

  • <u><em>H⁺</em></u>

Explanation:

There are three definitions of acids: Arrhenius, Bronsted - Lowry, and Lewis.

An Arrhenius acid is a substance that when dissolved in water will release a proton (H⁺ or hdyronoum, H₃O⁺) in solution.

The definition of Bronsted-Lowry is not limited to aqueous solution: an acid is a substance that releases protons in any solvent. So it includes, the Arrhenius acids but also other acids.

The Lewis Acid definition is wider. It includes both Arrhenius and Bronsted-Lowry acids and other substances that do not release protons. A Lewis acid is a substance that accepts an electron pair.

Thus, <em>when an acid is dissolved in a solution, following Bronsted-Lowry definition, </em><u><em>H⁺ ions are formed.</em></u>

How would you separate salt &amp; sand, taking into account the fact that salt is soluble in
fgiga [73]
The two can be mixed in water, since the salt is soluble it will dissolve and the sand will remain. To separate it from the water use filter paper and a beaker.

What is the empirical formula for a compound that is 83.7% carbon and 16.3% hydrogen?
zubka84 [21]
Hello!

We use the amount in grams (mass ratio) based on the composition of the elements, see: (in 100 g solution)

C: 83.7% = 83,7 g 
H: 16.3% = 16.3 g 

Let us use the above mentioned data (in g) and values will be ​​converted to amount of substance (number of moles) by dividing by molecular mass (g / mol) each of the values, lets see:

C:  \dfrac{83.7\:\diagup\!\!\!\!\!g}{12\:\diagup\!\!\!\!\!g/mol} \approx 6.975\:mol

H: \dfrac{16.3\:\diagup\!\!\!\!\!g}{1\:\diagup\!\!\!\!\!g/mol} = 16.3\:mol

We note that the values ​​found above are not integers, so let's divide these values ​​by the smallest of them, so that the proportion is not changed, let's see:

C:  \dfrac{6.975}{6.975} = 1

H:  \dfrac{16.3}{6.975} \approx 2.3

Note: So the ratio in the smallest whole numbers of carbon to hydrogen is 3:7, t<span>hus, the minimum or empirical formula found for the compound will be:

\boxed{\boxed{C_3H_7}}\end{array}}\qquad\checkmark

I hope this helps. =)

2H2+O2--&gt;2H2O, If you have 9 moles of Hydrogen gas (H2), how many moles of water can you form? (Enter just the number: not th
Naddika [18.5K]

If  you  have  9   moles  of hydrogen gas(H2)  the   moles of water that  can  be formed is   9 moles


<u><em>calculation</em></u>

2H2  +O2→ 2H2O

 The  mole  of H2O  is calculated   using the   mole  ratio.

that  is  H2:H2O  is   2:2  into simple form = 1:1

therefore if 9 moles  of  H2  reacted the   moles of H2O  =  9 x1/1  =  9 moles
