Answer:
0.0626 M
Explanation:
Equation of the reaction
CH3COOH(aq) + NaOH(aq) ---------> CH3COONa(aq) + H2O
Concentration of acid CA= ???
Concentration of base CB= 0.1943 M
Volume of acid VA= 10.0ml
Volume of base VB= 32.22 ml
Number of moles of acid NA= 1
Number of moles of base NB= 1
From
CA= CB VB NA/VA NB
Hence ;
CA= 0.1943 M × 32.22 ml × 1/10.0ml ×1
CA= 0.0626 M
Answer: The Moon can sometimes appear in the sky during the daytime because it is the closest object to Earth, and because its orbital cycle means that sometimes it is brighter in the day than at night.
The best answer among the following choices would be the fourth option D).
Answer:
a. neutron
Explanation:
A neutral atom has the same number of protons and electrons because in order for it to be a neutral atom the charges must be the same.
a neutron has no charge therefore it can be different then the number of protons and electrons in a neutral atom as it won't affect the charge.
