Electrically neutral molecules formed by covalent bonds between atoms that have the same or similar electronegativity are called Nonpolar.
Polar on the other hand is a term that describe a molecule with an asymmetrical distribution of charges. such a molecule has a negative pole and a positive pole.
A neutral atom has the same number of protons and electrons. Anytime an element has a charge, that means either more electrons or protons were added.
more electrons= negative charge
more protons = positive charge
Your charge is +3 which means there are 3 more protons than electrons
First answer is proton number is 21
The nucleon number means mass number which is protons + neutrons
24 + 21 = 45
Nucleon number is 45
Answer:
Explanation:
Hello there!
In this case, according to the given information and chemical equation, it turns out possible for us to calculate the moles of C2O4^2- by firstly setting up the equilibrium expression:
However, according to the question, we just need to apply the given 1:3 mole ratio in the chemical reaction, of iron (III) ions to oxalate ions to obtain:
