you have to have a....
1)hypothesis/observed
2)facts
3)experiment
that is all part of the scientific theory <span />
Answer:
k and be
Explanation:
because ionic bond occurs between a metal and a non metal
I would appreciate if my answer is chosen as a brainliest answer
1. different gases mix together to form air and no new comound is formed
2. air has variable composition
3. air shows the properties of its constituent substances
Answer:
a-Interatomic bonds
Explanation:
First of all, it is not a force. Let alone be molecular force.
The balanced equation for the reaction between NaOH and aspirin is as follows;
NaOH + C₉H₈O₄ --> C₉H₇O₄Na + H₂O
stoichiometry of NaOH to C₉H₈O₄ is 1:1
The number of NaOH moles reacted - 0.1002 M / 1000 mL/L x 10.00 mL
Number of NaOH moles - 0.001002 mol
Therefore number of moles of aspirin - 0.001002 mol
Mass of aspirin reacted - 0.001002 mol x 180.2 g/mol = 0.18 g
However the mass of the aspirin sample is 0.132 g but 0.18 g of aspirin has reacted, therefore this question is not correct.
