Answer:
Explanation:
Since, the atomic mass of the elements is a characteristic property of the elements, you can use the data given, number of moles and mass in grams of the product, to calculate the atomic mass of the product, and then compare with the atomic masses of the elements (information foun in any periodic table).
<u>1) Atomic mass of the product</u>:
- Atomic mass = mass in grams / number of moles
- Atomic mass = 604.4 g / 6.3 mol = 95.94 g/mol ≈ 94.9 g/mol (rounded to three significant figures)
<u>2) Periodic table:</u>
- Molybdenum, Mo, the element with atomic number 42, has atomic mass equal to 95.94 g/mol.
<u>3) Conclusion</u>:
So, you can conclude safely that the element you have produced is Molybdenum.
Answer:
The pressure of the gas is 224839.8 atm
Explanation:
As we know
PV = nRT
Substituting the given values, we get -
P * 1 L = 90.1 moles * 8.314 4621(75). J K−1 mol−1 * 300
P = 224839.8 atm
The pressure of the gas is 224839.8 atm
We can characterize properties of a substance to identify it because it helps us determine how the substance should be used. We can identify a substance by using physical or chemical properties. These help us by telling us which chemical we are looking at.
I hope this helps.. I wasn't sure what kind of answer you were looking for.
Answer:
Orbital, in chemistry and physics, a mathematical expression, called a wave function, that describes properties characteristic of no more than two electrons in the vicinity of an atomic nucleus or of a system of nuclei as in a molecule. ... A 1s electron occupies the energy level nearest the nucleus.

Answer:
The mass of zinc sulfide produced is 
Explanation:
From the question we are told that
The mass of zinc is 
The mass of sulfur is 
The molar mass of 
is a constant with value 65.39 g /mol
The molar mass of 
is a constant with value 32.01 g/mol
The molar mass of 
is a constant with value 97.46 g/mol
The reaction is
So from the reaction
1 mole of react with 1 mole of to produce 1 mole of
This implies that
65.39 g /mol of react with 32.01 g/mol of to produce 97.46 g/mol of
From the values given we can deduce that the limiting reactant is sulfur cause of the smaller mass
So
0.250 g of react with 0.250 of to produce 
of
So
Thus the mass of the mass of zinc sulfide produced is
