Answer: Stock nomenclature of 
is ammonium(I) nitrate
Explanation:
Stock nomenclature is used for chemical nomenclature where the oxidation states of some or all of the elements in a compound are indicated by Roman numerals in parentheses.
For example:
which has iron in oxidation state of +2 has stock nomenclature of iron(II) chloride.
which has iron in oxidation state of +3 has stock nomenclature of iron(III) chloride.
Thus the stock nomenclature of is ammonium(I) nitrate as ammonium has oxidation state of +1.
Answer:
Na₂CO₃ · 10H₂O
Explanation:
The formula for sodium carbonate hydrate is:
Na₂CO₃ · xH₂O
The unknown "x" is the number of water molecules contained in the hydrate.
To find "x" we have to use the hydrogen percentage in the sample, 7.05 % H.
First we calculate the molecular weight of Na₂CO₃ · xH₂O:
molecular weight of Na₂CO₃ · xH₂O = 23 × 2 + 12 + 16 × 3 + 18x
molecular weight of Na₂CO₃ · xH₂O = 106 + 18x g/mole
Now we devise the fallowing reasoning tanking in account 1 mole of Na₂CO₃ · xH₂O:
if in 106 + 18x grams of Na₂CO₃ · xH₂O we have 2x grams of hydrogen
then in 100 grams of Na₂CO₃ · xH₂O we have 7.05 grams of hydrogen
106 + 18x = (100 × 2x) / 7.05
106 + 18x = 28.4x
106 = 28.4x - 18x
106 = 10.4x
x = 106 / 10.4
x = 10.2 ≈ 10
The formula for the washing soda is Na₂CO₃ · 10H₂O.
Answer:
q=mAHf
Explanation:
When water change form from solid(ice) to liquid, it will need heat that depends on the heat of fusion(Hfus). If the form changed from liquid to gas it will use the heat of vaporization(Hvap) instead. The heat of fusion usually written just AT
q=MCAT is used to calculate heat when temperature change(AT = delta T= difference in temperature)
q=mAHvap is wrong because you need if the form change from liquid to gas
q=mc^2 is wrong because it describes the relation of mass and energy, not the form.
The answer should be q=mAHf
I can give you a clue of getting mass. if it is the atomic number is even multiply by 2 but if the atomic number is odd multiply by 2 and add 1
sodium atomic number = 11 so mass = 11*2 +1 = 23
oxygen. atomic number = 8 so mass = 8*2 = 16
carbon atomic number = 6 so mass = 6*2 = 12
True
Explanation:
The position of sodium on the periodic table makes the element a solid at room temperature is very correct.
- Sodium is an elements with 11 electrons in its shell.
- It is located in group 1 on the periodic table because it contains an outer valence electron.
- In a free state Na metal, the atoms exhibit metallic bonding.
- Metallic bonding is responsible for the solid nature of this alkali metal at room temperature.
- It is highly reactive because it has just one valence electron.
- Metals are usually found left of the periodic table.
