Answer:
233, 92 U
Explanation
I agree with your answer of 233 for the mass number (top number), but for the atomic number (bottom number) we need:
x + -1 = 91
Add 1 to both sides
x=92
Answer:
Temperature and Heat Temperature is the measure of the thermal energy of a substance. The hotter an object, the greater the motion of its particles, and the greater the thermal energy. Heat is the transfer or exchange of thermal energy caused by a temperature difference.
Explanation:
Since table salt is an ionic compound, the formula implies that numbers of Na+<span> ions, and Cl</span>-<span> ions are the same in the solid. The subscript numbers in an empirical formula should have no common divisor. A </span>structural<span> formula reflects the bonding of atoms in a molecule or ion.

Explanation:
In order to calculate the number of moles of a compound, we will find it out as follows.
No. of moles of chromium(III) chloride =
=
= 0.63 moles
No. of moles of =
=
= 5.88 moles
No. of moles of =
=
= 1.05 moles
No. of moles of =
=
= 1.02 moles
No. of moles of KCl =
=
= 1.34 moles
No. of moles of =
=
= 1.31 moles
No. of moles of =
=
= 6.25 moles
No. of moles of =
=
= 2.27 moles
No. of moles of =
=
= 1.11 moles
Therefore, we can conclude that out of the given options contains the largest number of moles of compound.
