Answer:
Several of the nonmetals are gases in their elemental form. Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).
Explanation:
The answer to your question is a 12
Answer:
The answer to your question is 1.25 moles of C
Explanation:
Reaction
5C + 2SO₂ ⇒ CS₂ + 4CO
Check that the reaction is balanced
Reactant Element Product
5 C 5
2 S 2
4 O 4
Use proportions to find the moles of C needed.
5 moles of C ----------------- 2 moles of SO₂
x moles of C ---------------- 0.500 moles of SO₂
x = (0.500 x 5) / 2
x = 1.25 moles of C
Your answer is A....They have the same number of protons and neutrons, but a different number of electrons. They have the same number of protons and electrons, but a different number of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers.....
