Answer:
Sodium reacts with the oxygen in air. It reacts vigorously with oxygen and the moisture that is already present in the air and thus catches fire.
It would be a bad idea to make coins made of sodium metal, beacause of their reactive nature.
What is reactive species?Those species which are not stable in nature and always ready to show reaction with another species, is known as reactive species.
Sodium metal is highly reactive in nature, means it easly reacts with the atmospheric oxygen and shows oxidation or with the moisture content of atmosphere as a result of which vigorously catches fire. That's why we don't use sodium to make coin.
Hence, beacause of reactive nature sodium is not used.

Ok buddy- so if you grab your periodic table there should be numbers on the side... (REFER TOO IMAGE ONE) So then we find them on the periodic table... (REFER TO IMAGE TWO) and if we look at the number the higher it gets the more radioactive it gets, and thats why it stops because the atomic gets so high that the level can't even be able to be mad because it will just explode and when it does that its dangerous because of how radioactive it is... so if we look the more "gas" concentrated elements are seen at the top (i.e. the helium) So the order would be He, C, O, Ne, Ca, I
Then just do that for the rest of them and the numbers on the side are the positive (+) or negative (-) amount of atoms that the atom is missing or ha to be stabilized or over stabilized, but you will learn that later on when you go into periodic equations.
Hopefully this helped, have a wonderful day! :)
How many particles are in 3.4 moles of HCl?
Answer:
The volume is 77 L.
Explanation:
where P is pressure, V is volume, n is moles, R is the gas constant, and T is temperature in Kelvins.
The current STP temperature is 0∘C or 273.15 K (used for gas laws), and the pressure is 105Pa, which most people write as 100 kPa (both pressures are equal).

Explanation:
If 36.5 m of a gas are collected at a pressure of 755 mm Hg, what volume will the gas
occupy if the pressure is changed to 632 mm Hg?
Answer:
Is there any answer options?, if not the answer is V2= 43.6m3
"The volume of the gas is calculated Boyles law. If 36.5 m of a gas are collected at a pressure of 755 mm Hg, then the volume of the gas will be 43.6 [tex]m^{3}[/tex]"
What is Boyles Law?
Boyle's law, also known as the Boyle–Mariotte law or Mariotte's law, would be an experimental gas law that specifies that how pressure of a gas decreases as the container capacity increases.
It can be represented by the formula:
[tex][P_{1} V_{1} =P_{2} V_{2}[/tex]
It is given that, [tex]P_{1}[/tex]= 755 mmHg, [tex]P_{2}[/tex] = 632 mm Hg, [tex]V_{1}[/tex]= 36.5[tex]m^{3}[/tex]. [tex]V_{2}[/tex]= ?
Now, put the value of given data in above formula:
[tex]V_{2}[/tex] = 755× 36.5/632= 43.6 [tex]m^{3}[/tex] .

How many moles of Mg3(PO4)2 are in 350.00 grams of Mg3(PO4)2?
Answer:
1.3 moles/ 1.33150727 moles
Explanation:
350g x 1 mol/262.86g = 1.3 moles
The molar mass of Mg3(PO4)2 is 262.855 g/mol
Atomic weight of the parts:
Mg 24.3050 x 3 = 72.92
P 30.973762 x2 = 61.95
O 15.9994 x8 = 127.995
There are 262.855 grams in one mole, so
350.00 g x (262.855g/1 mole) = 1.33 moles Mg3(PO4)2

nutrients where they need to go.
B: It doesn't
C: The enteric nervous system's network of nerves, neurons and neurotransmitters extends along the entire digestive tract - from
the esophagus, through the stomach and intestines, and down to the anus.
D: The muscular system allows for movement within the body, for example, during digestion or urination.
Answer:
the answer is not d because you can pee without moving. so its a because without the food nutrient no part of our body can work
