Answer:
22.5
Explanation:
all you have to do is take the number of moles of al and multiply them by sulfuric acids mole ratio as given in the equation (3), then divide by aluminums mole ratio number (2). then you will have moles of sulfuric acid.
*note: this only works if you are going moles to moles, if you are converting to anything else, this will NOT work*
if you have any questions leave them in the comments and i will try to answer them, if this helped, pls give a brainly
The correct statement to fill the blank would be the first option. Atomic energy is the energy in the nucleus of an atom of electrons and their shells. From the word atomic itself, we can say that this energy is energy within and carried by the atoms.
Kingdom Monera, organisms in this Kingdom are prokaryotes, they don't have a nuclear envelope, thus they have a nucleoid.
Answer:
because when you burn some wood you don't just get ash, you also get energies like thermal energy(heat), light and also some gaseous compound are produced (like CO2, SO2 etc) for the combustion reaction(a reaction where something is burnt in presence of O2). So the energy reserved in the wood are transformed into heat, light, other compounds and some turn into ash.
Answer:
2.48 g
Explanation:
From the question given above, the following data were obtained:
Number of atoms = 2.53×10³⁴ atoms
Mass of Ni =?
From Avogadro's hypothesis,
we understood that 1 mole of any substance contains 6.02×10²³ atoms.
Therefore, 1 mole of Ni contains 6.02×10²³ atoms.
Recall:
1 mole Ni = 59 g
Therefore, 59 g of Ni contains 6.02×10²³ atoms.
Finally, we shall determine the mass of 2.53×10³⁴ atoms of Ni. This can be obtained as follow:
6.02×10²³ atoms = 59 g
Therefore,
2.53×10³⁴ = 2.53×10³⁴ × 59 / 6.02×10²³
2.53×10³⁴ atoms = 2.48 g
Thus, the mass of 2.53×10³⁴ atoms of Ni is 2.48 g.
