Answer:
3.43 moles
Explanation:
To convert moles into grams you must take the number of grams and divide it by the atomic mass of the compound.
in this case, grams is 151 and N2O has an atomic mass of 44.013
so your equation would look like
151/44.013=3.430804535
your answer would be 3.43 moles
Answer:
16 mg of water can be produced by 7.1×10⁻³ g of CH₄
Explanation:
This is the reaction:
CH₄ + 2O₂ → CO₂ + 2H₂O
In a combustion, oxgen is a reactant with another compound, and the products are always water and carbon dioxide
1 mol of methane can produce 2 moles of water. Ratio is 1:2
If we convert the mass to moles → 7.1×10⁻³ g . 1 mol/ 16g = 4.43×10⁻⁴ mol
In this reaction I would produce the double of moles I have from methane, so If I have 4.43×10⁻⁴ moles of methane I would produce 8.87×10⁻⁴ moles of water.
What mass of water, corresponds to 8.87×10⁻⁴ moles?
8.87×10⁻⁴ mol . 18g / 1mol = 0.016 g which is actually the same as 16 mg
A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.
C.Ions with greater charge are more soluble in water.
Explanation:
Compounds with small ions tend to be less soluble than those with large ions.
The solubility of a compound is the result of a competition. The ions in the compound attract each other, and the water molecules attract the ions.
If the water molecules have a greater attraction to the ions than ions have for each other, then the compound will be soluble in water.
Compounds with small ions are less soluble than compounds with large ions. Small ions are closer to each other, so they have strong attractive forces. It is more difficult for the water to break them apart, so they are less soluble.
