Answer:
Explanation:
Imagine a chemistry set in front of you
False you should only tell your teacher
You should not wear dangling jewelry and loose clothing and sandals so all of the above. Jewelry what if your leaning over to get something it will get caught Sandals what if glass falls and breaks in your foot and loose clothing it will get caught on fire. You should never horseplay ever. You should see the school nurse if you get hurt.
Hope this helps a little :)
Answer:
Explanation:
The reaction can be represented by this nuclear equation: 23892U → 23490Th + 42He + Energy.
Answer:
The limiting reagent is CuCl
Explanation:
The initial number of moles of aluminum, Al = 4.5 moles
The number of moles of copper, Cu = 6.5 moles
The given chemical reaction is presented as follows;
2Al + 3CuCl → 2AlCl₃ + 3Cu
Therefore, we have, 2 moles of aluminum combine with 3 moles of CuCl produces 2 moles of AlCl₃ and 3 moles of Cu
1 mole of Al will combine with (3/2) moles of CuCl,
Therefore, 4.5 moles of Al will combine with (4.5 × (3/2) = 6.75) 6.75 moles of CuCl
Given that the number of moles of CuCl present is only 6.5 moles which is less than the 6.75 moles required to combine with the 4.5 moles, the 6.5 moles of CuCl limits the amount of AlCl₃ and Cu produced, and therefore the CuCl is the limiting reagent.
False
any neutral object will be affected by the use of a charged object they will both attract regardless if the charged object is positively charged or negatively charged
