Answer:
solid
Explanation:
because solid has a definite shape and volume
Answer:
The radioactive decay mode that does not result in a different nuclide is gamma decay. In gamma decay, the only product is a gamma ray photon.
Explanation:
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.
2.07 M is the molarity of the final solution if 45.0 ml of 6.00M HCl is added to 130 ml of 
O.
Explanation:
Data given:
volume of HCl, V1 = 45 ml
molarity of the HCl solution, M1 = 6 M
final volume of the HCl solution after water is added, V2 = 130 ml
final molarity M2 =?
After the dilution, the molarity of the new solution can be found by using the formula:
M1V1 = M2V2
here M1 and V1 are the molarity and volume for concentrated solution, M2 and V2 represents the diluted solution's molarity and volume.
Applying the formula after rearranging the equation, we get
M2 = 
M2 = 
M2 = 2.07 M
The final molarity of the HCl solution is 2.07 M
