Either covalent compounds are neutral, covalent compounds share electrons
Answer:
Rewrite the following sentence in reported speech
The chair person said,"A hearty welcome to all present!"
Answer:
ions
Explanation:
Individual atoms of the same element but having slightly different number of protons and electrons are called ions.
Ion is a charged particle.
- An atom is made up of three fundamental subatomic particles.
- Protons are the positively charged particles
- Electrons are the negatively charged particles
- Neutrons do not carry any charges.
When the number of protons > electrons the body is positively charged.
When the number of electrons > protons the body is negatively charged.
Charged particles are called ions.
First, make sure to balance your equation.
3H2(g) + N2(g) ⇄ 2NH3(g)
Now, you can write your Kc expression. Remember that Kc is products over reactants, and the exponent for each product or reactant is based on its coefficient.
Kc = [NH3]^2 / [H2]^3[N2]
Assuming the person has about 154 pounds (70kg) the weight of an average human. There would be around 7000000000000000000000000000 atoms
or 7 x 10^27
