20. Follow the directions of Question 19 for the following acids: (a) hypochlorous acid (b) formic acid, $\mathrm{HCHO}_{2}$ (c) acetic acid, $\mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2}$ (d) hydrobromic acid (e) sulfurous acid

In this problem, See ACL two HD one which age among the following. So the answer will be See ACL two. While the other compounds, such as the u s 045 page to be, is here to us to appear so for seven H two are not follow the rules. So option B, correct answer for this problem. Uh huh.

In this problem we have to ride the gondola or two minus. So just look at it carefully. JK sigma s sigma 22 sigma. Do as two Take my Star to add to Sigma two. period too 5 2, PX two By two, P.Y two by star, who P x two by style two py two py one. So bond order Is equal to 8 -5 x two, which is equal to 1.5 according to the option option. Age, correct here.

Plant hormones help coordinate growth, development and response to environmental stimuli. They are produced in very small quantities. However, they have a profound effect on the plant because the hormone signal is amplified. Hormones can have multiple effects on a plant, and they can work synergistically with other hormones or in opposition to them. So let's begin by looking at an overview of plant hormones and what they stimulate. Ox ins enhance April dominance or the upward growth of the plant toward the sun rather than growing laterally. Se Jokinen's Stimulate Psychokinesis and Cell division give her ruins. Promote stem and leaf elongation obsessed IC acid, inhibits growth and promotes see dormancy. And finally, ethylene promotes ripening. Let's take a closer look at the plant hormone oxygen's. We know that they enhance a pickle dominance the preferential growth of a plant upward rather than laterally. The terminal bud actually suppresses lateral growth by suppressing development of axial buds. Oxen stimulate stem elongation and growth by softening cell wall ox ins were the first plant hormone discovered. Humans are able to synthetically create options in the lab, and it's used as a weed killer. They're also used as a rooting powder to develop roots quickly in a plant cutting. And finally, a synthetic oxen sprayed on tomato plants will induce fruit production without pollination. This results in seedless tomatoes. So, as you can see, oxen is have multiple stimulations. They produce multiple effects on plants, one of which is to promote rooting, which you humans have created in a rooting powder. Yeah.

In this video, we're going to be talking about some examples of weak and strong acids and bases. So our first example is going to be hypo glorious acid. So hypo glorious acid has this formula and hyper chorus acid is a weak acid. So by definition a weak acid does not associate 100% when it is in solution. The ph value is going to be less than seven, but it is not going to be as low as a strong acid. If you compare this two perk Lorik acid, you can see that, that this acid, the hipaa Cloris acid has less electro negative oxygen atoms in it, so it has less electra negative atoms pulling the electrons away from the hydrogen. When the electro negative atoms pull the electrons away from the hydrogen, it makes the hydrogen easier to lose. So therefore it's easier for this poor cork acid to give up its hydrogen. So that explains why we would have hyper Cloris acid as a weak acid versus the poor clark acid, which is a strong acid. Now, let's look at another example. Another example is going to be formic acid, former gas. It is also a weak acid. It does not associate 100% former gas. It is produced by ants. So you wouldn't really expect it to be strong because usually when you touch an ant, you never really experience anything too dangerous when interacting with them. So that's the way to remember that this is a weak acid formic acid. So again, ph will be less than seven but it won't be as low as the ph of a strong acid. Now, let's talk about another example. This is a very common example. This is acetic acid, acetic acid is found in vinegar and you will work with this acid in the lab quite often, it is weak and relatively safe to work with. Yeah, hydro veronica acid, on the other hand, is a strong acid. The reason is because hydro brahmanic acid has hydrogen paired with one of the group seven and ions where the hell agents when we have hydrogen paired with the group seven and ions, they're always going to end up being strong acids. With the exception of HF, which is actually a weak acid. The last example is sulfurous acid, which has this chemical formula. This is also a weak acid. So two understand why this is a weak acid. We can compare the formula of sulfurous acid to sulfuric acid and we see that the sulfurous acid has less of the electro negative oxygen atoms in its formula. So again there are less electro negative atoms pulling the electrons away from the hydrogen. And this makes the hydrogen harder to be lost from this molecule. So that will weaken the strength of the acid. And that's why that's a weak acid.
