Answer:
D
Explanation:
I don't exactly remember his four points, but the D. is just not true anyway. For example, a molecule of water (H20) does that have the same properties or mass as Nitrogen dioxide or sulfer dioxide or something else
Answer:
C. He
Explanation:
When lithium is ionized, its new electronic configuration is the same as that of a helium atom.
Lithium is made up of 3 electrons with a configuration of:
2, 1
it has 1 electron in its outermost shell.
As a metal lithium will prefer to lose an electron due to its electropositivity.
On losing an electron, it will have 2 electrons remaining
Now, Helium has 2 electrons and this makes it similar to Lithium that has lost one electron.
This makes Lithium isoelectronic with Helium.
20 calories equals to 8.368 joules.
4.184 J is needed to raise 1 gram of water.(Heat capacity of water)
for 2 grams of water 8.368 joules.
So the answer is 16 c.
F - 12.5
Cs - 87.5
F mass - 19
Cs mass - 132.91
For example, certain medications may influence the results of the test.
Drug test can show the presence of illicit or prescription drugs on hair samples, although the person has not used these drugs.
Some of false positive drug use is because of this medications: antihistamines, decongestants, antibiotics, antidepressants, analgesics and antipsychotics.
