There are 3 elements if the 0 is an O but 2 if not
a compound is a molecule made of atoms from different elements.
a. by the combination of an unlimited number of elements
number of particles= number of mol × avogadro's number (6×10²³)
hope this helps :-)
1 mol of any particle has 6.02*10^23.
A. 4.8 mol Cu* 6.02*10^23 (1/mol) ≈2.9*10^24
B. 5.6x10^-3 mol C *6.02*10^23 (1/mol) ≈3.4*10^21
C. 20.0 mol Hg*6.02*10^23 (1/mol)≈1.2*10^25
D. 0.285 mol Na*6.02*10^23 (1/mol)≈1.7*10^23
by the combination of an unlimited number of elements
Answer. i think that the answer is D hope it helps :)
Compounds are formed by bonding atoms of two or more different elements through chemical reaction. Atoms are bonded by losing or gaining electrons in ionic bonding and by sharing electrons in covalent bonding between two atoms participating in the bond formation. For example, one molecule of the compound water is formed by bonding two atoms of hydrogen and one atom of oxygen by sharing electrons between the atoms and forming covalent bonds. Therefore, compounds are created by losing, gaining or sharing electrons between other atoms.
(Answer) (D) By losing, gaining, or sharing electrons between other atoms.
Each molecule contains one atom of A and one atom of B. The reaction does not use all of the atoms to form compounds.
A + B ⟶ Product
Particles: 6 8 6
If six A atoms form six product molecules, each molecule can contain only one A atom.
The formula of the product is ABₙ.
If n = 1, we need six atoms of B.
If n = 2, we need 12 atoms of B. However, we have only eight atoms of B, so the formula of the product must be AB.
Thus, 6A + 6B ⟶ 6AB, with two B atoms left over.
