Checking if it is balanced:
C
3 3
H
8 4*2 = 8
O
8 3*2 + 4 = 6 + 4 = 10
8 10
Only O is not balanced.
So O is violating the law. Option C.
<span>C. O</span>
<span>The effective nuclear charge of an atom = total electrons - inner electrons
For O, ENC = 8 - 2 = 6
For Li, ENC = 3 - 2 = 1
For C, ENC = 6 - 2 = 4
The electrons in O experience the greatest effective nuclear charge and that is why O is smaller than C (which is smaller than Li).</span>
Answer:
0.71
Explanation:
The molecular mass of NaCl is, 23+35.5
= 58.5
1 mole means molecular mass (in gram)
In 58.5 gm NaCl there is 1 mole.
So, 42.1 gm NaCl contains 42.1/58.5 =0.71 moles.
Well, you just have to look for the one that does not have any positive/benefit.
1. is not the answer, since vaccines prevent countless people from disease and death.
2. is not the answer since animal abuse is not okay and the statement shows that science has become more efficient, therefore helping society become more efficient
3. is definitely not a positive effect that biotech has had on society. antibiotic-resistant bacteria endangers everyone. Therefore, this is the answer :)
4. is not the answer because helping people with diabetes be able to afford their medication is very helpful.
Answer:
1. Water can separate from salt solution by simple distillation
2. Simple distillation happens through a process heating and cooling liquids in order to separate the purify them, first, a liquid is heated producing a vapor, then, that vapor is cooled in a small tube called a condenser in order to form a separate liquid that liquid, sometimes referred to as the distillate, falls from the condenser into a separate container, the process works because it to liquids in the original vaporized a different point, meaning, the vapor that is created is comprised entirely of just one of the liquids in order for a simple work the 2 liquids boiling point must have been between at least 25 degrees Celsius about 77 degrees Fahrenheit
Explanation:
ig u can get info from the 2. to help u srry I don't feel like correcting my grammar but I hope that makes sense :)
