Answer:
<u>7.44 grams CaCl2 will produce 10.0 grams KCl.</u>
Explanation:
The equation is balanced:
I've repeated it here, with the elements corrected for their initial capital letter.
CaCl2( aq) K2CO3( aq) → 2KCl( aq) CaCO3( aq)
This equation tells us that 1 mole of CaCl2 will produce 2 moles of KCl.
If we want 10.0g of KCl, we need to convert that mass into moles KCl by dividing by the molar mass of KCl, which is 74.55 grams/mole.
(10.0 grams KCl)/(74.55 grams/mole) = 0.1341 moles of KCl.
We know that we'll need half that amount of moles CaCl2, since the balanced equation says we'll get twice the moles KCl for every one mole CaCl2.
So we'll need (0.1341 moles KCl)*(1 mole CaCl2/2moles KCl) = 0.0671 moles CaCl2.
The molar mass of CaCl2 is 110.98 grams/mole.
(0.0671 moles CaCl2)*(110.98 grams/mole) = 7.44 grams CaCl2
<u>7.44 grams CaCl2 will produce 10.0 grams KCl.</u>
Answer: 25.3
Explanation:
The question aks to convert 19 quibs, which is the amount of skvarnick that you obtained, to sleps.
Since, you are given the equivalence between sleps and quibs, you can build your own conversion factor, which is how the sciientific calculations are made:
- equivalence: 4 sleps = 3 quibs
- divide both sides by by 3 quibs: (4 sleps / 3 quibs) = (3 quibs / 3 quibs)
- simplify: 4 sleps / 3 quibs = 1 ← conversion factor
Now, you can multiply 19 quibs by the conversion factor:
- 19 quibs × 4 sleps / 3 quibs = 76 / 3 sleps ≈ 25.3 sleps. ← answer
The quibs units cancel out since they are in the numerator and denominator, leaving only sleps.

Answer:
The answer to that question is 24 AMU.
Explanation:
I know this because i got the answer correct on the quiz. To get the average, you just add the 4 atomic masses given to you together then divide by 4.
1. Make sure it isnt something other than a ghost(i.e. something falling)
2. Record what you see and hear
3. See if anyone hears the same thing as you(unless your home alone)
4. Be confident and dont be fearful because ghost sense fear
5. Pray or perform an exorsism( if this is part of your religion)
6. After the ghost leaves, clean up.( like literally mops the floors and stuff. it keeps the ghosts out)
Good Luck ! :]
