For the atom to be neutral, it must have the same number of electrons and protons. The aromic number indicates the number of protons. Since Carbon has 6 protons, it would have to have 6 electrons for it to be neutral
Answer:
Mixture
Explanation:
When a prospector scoops up part of the stream bed, the pan contains stream sediments.
The initial concentration was 8.45M
Step 1: Given data
Initial concentration (C₁): ?
Initial volume (V₁): 635 mL = 0.845 L
Final concentration (C₂): 6.00 M
Final volume (V₂): 1.19 L
Step 2: Calculate the initial concentration
We have a concentrated NaCl solution and we want to prepare a diluted one. We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
C₁ = C₂ × V₂ / V₁
C₁ = 6.00 M × 1.19 L / 0.845 L
C₁ = 8.45 M
Thus, The initial concentration was 8.45M
