Cells make up tissues. Tissues make up organs, organs make up systems, systems make up organism
HNO₃(aq) +Ca(OH)₂(aq) --> H₂O(l) + Ca(NO₃)₂(aq)
It is Ca(NO₃)₂ because NO₃ has a charge of -1, and Ca has a charge of 2+. And when writing an ionic compound, you take the charge of 1 and write it as the subscript of the other.
Now let's balance the equation and then find the net ionic equation.
2HNO₃(aq) +Ca(OH)₂(aq) --> 2H₂O(l) + Ca(NO₃)₂(aq)
2H⁺(aq) + 2NO₃⁻(aq) + Ca²⁺(aq) + 2OH⁻(aq) --> 2H₂O(l) + Ca²⁺(aq) + 2NO₃⁻(aq)
We can get rid of the spectator ions. These are the ions that are on both sides.
We are left with
2H⁺(aq) + 2OH⁻(aq) --> 2H₂O(l)
We can simplify the net ionic equation down to
H⁺(aq) + OH⁻(aq) --> H₂O(l)
Answer:
well idk but i will take the points
Explanation:
This doesn't happen in mitosis. Mitosis is preceded by interphase. Interphase has three phases: G1, S and G2. What you call chromosome doubling happens in S phase.
They have different amounts of neutrons.
Do u know why? Ok, because they are both cacbon, so they have the same amounts of protons : 6.
