Answer:
2:8:7
Explanation:
The first shell can accommodate a maximum of 2 electrons, while the second level accommodates a maximum of 8 while the third last cell takes up the remaining 7 electrons
12.992 or 13 (rounded) hours
If you convert 1150km to miles it will be approximately 714.577 miles , now 714.577/55=12.992309090909090

Precision
Explanation:
It figures out how close all of the data numbers are.
Answer:
100 mL is the volume of HCl needed to neutralize the 44.3 of Ba(OH)₂
Explanation:
This is the chemical equation:
2HCl + Ba(OH)₂ → BaCl₂ + 2H₂O
Formula for neutralization is:
Molarity of acid . Volume of acid = Molarity of base . Volume of base
0.121 . Volume of acid = 0.274 . 44.3
Volume of acid = (0.274 . 44.3) / 0.121 → 100
<u>Answer:</u>
<em>The sign of work for this process will be Negative.</em>
<em></em>
<u>Explanation:</u>
Work done by the system on the surroundings is negative
So, If work is done on the system, its sign is positive. If work is done by the system, its sign is negative
Here we see the system that is argon gas is expanding and the work is done by the system into the surroundings (vessel) and the sign is Negative
Therefore, the sign of work for this process will be Negative.
