The question is: The pH of lemon juice at 298 K is found to be 2.32. What is the concentration of H3O (+) ions in the solution. So, you just have to use the formula pH = log { 1 / [H3O+] } = - log { [H3O+] }, from which you can solve for [H3O+] as: [H3O+] = 10 ^ (- pH) = 10 ^ (-2.32) = 0.00479 M = 4.79 * 10^ -3<span> Answer: 4.79 * 1 0^-3M</span>
Yes. It is made from baking soda and shaving cream but shaving cream is a constant. You could use things like corn flour instead of baking soda.
Answer:
Alkane
Explanation:
Alkane is a class of organic compounds that contain only carbon and hydrogen and the carbon atoms are connected to each other by single bonds.
Now, if we look at the molecule whose condensed structural formula is shown in the question, we will notice that the compound can only contain single bonds. That is, the molecule is a saturated hydrocarbon(alkane).
I have drawn out the full structure of the compound to illustrate this point.
Explanation:
The given compound is:
AlCl₃
- ionic formula - it is a combination between a metal and non - metal with an electronegativity difference greater than 0.7
- 3 chlorine atoms - from the compound, we see that the compound is made up of 1 aluminum atom and 3 chlorine atoms.
- Aluminum is the cation
- Chlorine is the anion
A cation is the positively charge specie and the anion is the negatively charged one.
Al³⁺ + 3Cl⁻ → AlCl₃
