Answer:
Number of moles = 2 mol
Explanation:
Given data:
Mass of carbon = 24 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of carbon is 12 g/mol.
Now we will put the values in formula.
Number of moles = 24 g/ 12 g/mol
Number of moles = 2 mol
Answer:
Stronger!
Explanation:
The <u>stronger</u> the forces among the particles in a sample of matter, the more rigid the matter will be.
Explanation:
Chlorine gas bleaches the damp litmus (red or blue). Bleaching is an oxidation process.
Answer:
Transition elements are elements which have partially filled d-orbitals and form at least one or more stable ions.
2.2 x 10^-2
0.055 / 250 = 0.00022 - This would be 2.2 x 10^-4, but the question is asking for percent, not proportion, so multiply by 100% to get the percentage.
0.00022 * 100% = 0.022% = 2.2 * 10^-2
