Question

Copy and complete the table.

Noah Barguez-Arias · Accepted Answer

for this problem, we need to fill out a table. And in order to fill out this table, we need to know about Allah. God Rose number. So what is Alba cadres? Number precisely. It is 6.22 times 10 to the 23. That&#x27;s just an amount. 6.22 times 10 to 23 is just a number, but it is tied strongly to a common unit of measurement in chemistry known as the mole. Now it relates, because avocados number is the number of atoms within a more. So, If you were to say, um, some element say, hydrogen, one mole of hydrogen would be six point would have 6.22 times 10 to 23 atoms within it. So that&#x27;s most of what you need to know for this problem. But one additional thing is that you should know about an element&#x27;s atomic mass. Now, if you look at the periodic table and you look at the bottom of each elements box, you&#x27;ll see a series of numbers that&#x27;s the atomic mass and the atomic mass basically states the number, the amount of grams, the number of grams that are within one mole of that substance. So let&#x27;s say for hydrogen which has an atomic mass of one, one mole of hydrogen is approximately 1 g. So 6.22 times 10 23 23 atoms of hydrogen would be would have a mass of one grant. Alright, Without out of the way, let&#x27;s move to the table itself. The first row was already filled out for us and we can use that to help us fill out the rest of this table. So let&#x27;s take a look at this first one. We have 24 g of carbon. That is twice the amount of what was in the first row. And we know that in the first row it&#x27;s 12 g of carbon was one mole. So all we need to do for this one is double that amount. So 12 g was one more 24 g is two moles and with the number of atoms, we are going to have to write this out. But all you need to do is just multiply the first three numbers. In our case, it&#x27;s 602. We multiply 602 by two. We get 1204. So you just write that out. 1204 and then right. Seven sets of zeros. That&#x27;s one. Now it&#x27;s seven sets of zeros because the scientific notation is 23 which is basically the number of numbers. And if you multiply seven by three, you get 21 and you add these four numbers. You get 24. So, yeah, all you need to do for the scientific notation is right. These first two numbers, it&#x27;s 1.2 times 10 to the 24. All right, now let&#x27;s move on to the second one. We have 40 g of calcium. I want you to look at the periodic table and look for calcium theater. Tomic Mass of calcium is 40 g, so we know that 40 g of calcium is equal toe one more. So now I just fill out the rest of this table like we did like what was written in the first row. So that&#x27;s 602 followed by seven sets of three zeros. Scientific notation is like the&#x27;s standard avocados. Number 6.2 times 10. The 23 now the last 1 20 g of calcium. That is half the amount of our last one. So we know that it is half the amount of moles so 0.5. And for writing out the number of atoms, you just have to divide the first three numbers. You have 602. You divide that by two, you get 301 and in the seven sets of zeros Okay, okay. And for scientific notation, you take the first three. We put a decimal, you know, one, it was 10 to 23. So you go. This is your filled out table using avocados number.

on this next question. It wants us to complete the table that they give us. This is Special Nation gives us ass, and it gives us some values for us to buy. Six wants extra. The negative first. So to to the negative. First is 1/2 five. The negative first is 1/5 and six. The native first is one sex. So these are the answers.

Kimberly Konzack · Answer

in this question. Question 20. They just want us to really do the reciprocal of each of the values they give us. They give us acts and x the negative first. Okay, So that this is 1/3. And this one over eat. And this is one of your seven. Excellent. A good first that we did one over x of the first one over X to the 1st 1 over X to the first. So therefore this X here great must be three. Because three to the negative first would be won over three. This must be eight. Because eat the negative first would be won over eight. This must be seven. Because seven to the negative first would be won over stuff.

okay. To solve this question, we need to use the techno magic. I don&#x27;t really stand on because I want to solve for a right. We know that the opposite over adjacent is stand off. The anger so opposite over adjacent, is equal to tan. 40. Fight it. And since we&#x27;ve no time for the physical to one, you can say that a is B, which in this case is too likely something for C. Wright. Now for this views. Cool Site co signed a 45. It&#x27;s opposite is adjacent upon hypothalamus, which is be oversee implies that c There&#x27;s nothing but tour t times. One moment costs for the fight now cost 45 is nothing but one over there too. So this becomes real proof. I, despite you, comes through too. So then we have to do to over three

Kami Dupree · Answer

Okay, All right. This question were provided with the diagram of a 45 45 90 triangle. We are given that a side a is the square root of five and rest to find the sides of the lengths. Let&#x27;s B and C note that in this diagram, sides A and B are both the legs of the triangle. Side C is the high partners, and we know from the 45 45 90 the&#x27;re, um that the sides length will be the same and that the hype oddness will be the square root upon news is the square root of two times Ah lake. So we know that sends A and B are the legs. They must be the same length. If a is the square root of five, then be must also be the square root of five. And then to find the hypothesis, we want to take the square root of two Tinus the lake. So we could also write that a little bit nicer. I think this way it doesn&#x27;t matter. Either way, it&#x27;s up to you. But see then will be the hypothesis which will be the square root of two times the lake. So the square root of two times the square root of five. This, of course we can say, is the square root of two times five or the square root of 10.

Since we know the value off, see the high part news we can use signed and co science to find the values of N respectively. Let&#x27;s start it. Signed. Signed off 45 is nothing but opposite upon my prognosis is a over 14. All right, since, um uh, see is reporting rearranging we find that is equal to 14 over. Look, too, because sign of 45 to 1 over two, which if we expand the route, is nothing but seven. Similarly, he was cost 45 which is also equal toe one a little too. We use adjacent bond high pot meals which become which implies that the is equal to again 14 over too through seven. Therefore, B and es are equal.

Answer

24g C is 2 moles, which is 1,204,000,000,000,000,000,000,000, or $1.2x10^{24}$, atoms.
40g Ca is 2 moles, which is 602,000,000,000,000,000,000,000, or $6.02x10^{23}$, atoms.
20g Ca is 0.5 moles, which is 301,000,000,000,000,000,000,000, or $3.01x10^{23}$, atoms.
