<u>Answer:</u> The correct answer is isotopes generally have the same chemical properties, but often different nuclear properties.
<u>Explanation:</u>
Isotopes are defined as the chemical species of the same element which have same atomic number but differ in their mass number.
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Nuclear properties of an element is determined by the number of protons and neutrons present in a nucleus.
Chemical properties of an element is determined by the number of electrons present in an atom.
Isotopes have same atomic number, this means that they have same number of protons and electrons but they differ in mass number, which means that they differ in number of neutrons.
Hence, isotopes will have same chemical properties but different nuclear properties.

Answer:
The molar mass of C6 H12 O6 is 180.15588 g/mol.
Explanation:
B) 1.50 mol
Since O2 and H2O are in a 1:2 ratio, multiply 0.75×2 = 1.50
Answer:
1.18 moles of CS₂ are produced by the reaction.
Explanation:
We present the reaction:
5C + 2SO₂ → CS₂ + 4CO
5 moles of carbon react to 2 moles of sulfur dioxide in order to produce 1 mol of carbon disulfide and 4 moles of carbon monoxide.
As we do not have data from the SO₂, we assume this as the excess reagent. We convert the mass of carbon to moles:
70.8 g / 12 g/mol = 5.9 moles
Ratio is 5:1, so 5 moles of carbon react to produce 1 mol of CS₂
Then, 5.9 moles will produce (5.9 . 1) / 5 = 1.18 moles
