Answer:
0.59 mol Na2CO3
Explanation:
M(Na2CO3) = 2*23.0 + 12.0 + 3*16.0 = 106 g/mol
63 g Na2CO3 * 1 mol Na2CO3/106 g Na2CO3 = 0.59 mol Na2CO3
Answer:
A. electrons simultaneously attracted by more than one nucleus
Explanation:
- Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values.
- It is the bond which is generally occurs within non metals as they share electrons to complete their octet.
- The difference in the electronegativity values of the atoms involving in a covalent bond must not exceed the value of 1.7 .
Thus, the electrons are attracted by the two different nucleus of the atoms that are taking part in the bonding.
<u>So, the correct answer is:- A. electrons simultaneously attracted by more than one nucleus</u>
Electric current is electric charge in motion. It can take the form of a sudden discharge of static electricity, such as a lightning bolt or a spark between your finger and a ground light switch plate. ... Protons have positive charge, while electrons have negative charge. Hope this helps
