The correct answer is B. The nitrogen in the nitrogen cycle originate from the atmosphere. It forms approximately 78% of the Earth's atmosphere. However, this form is not usable because it is in its most stable form therefore unreactive. This nitrogen gas needs to be converted into nitrate compound for it to be usable. Then, the nitrogen cycle starts.<span />
D. 18 x 10^23 is the total number of atoms in 1.0 mole of CO2
Answer:
Explanation:
<u>1) Data:</u>
a) V₁ = 38.2 liter
b) P₁ = 91 psi
c) V₂ = 77.4 liter
d) P₂ = ?
<u>2) Formula:</u>
According to Boyle's law, at constant temperature, the pressure and volume of a fixed amount of gas are inversely related:
- PV = constant ⇒P₁V₁ = P₂V₂
<u>3) Solution:</u>
- Solve for the unknown: P₂ = P₁V₁ /v₂
- Substitute the values: V₂ = 91 psi × 38.2 liter / 77.4 liter = 44.9 9si ≈ 45 psi.
Answer:
a)there would be no reaction
Explanation:
The activity series of metals has many functions. The one applicable to this problem is that it can be used to determine whether a reaction will occur or not. Also, based on the positions of metals in the series, we can know how reactive a metal is compared to another.
In a single displacement reaction, a metal replaces another metal based on their position on the activity series. Metals that are higher in the series are generally more reactive than others below them and so will displace them.
Would aluminum replace magnesium to form a new compound or would there be no reaction?
Magnesium is higher than aluminum in the activity series. Therefore it is more reactive than aluminum. No reaction will occur.
