Nonpolar Covelant is the correct answer for PLATO users.
Answer:
the additional concentration of nitrogen = 0.04748 mg/L
Explanation:
From the given information:
The mass of the nitrogen added to the field per year = 10% of 1300.0 kg
=
= 130 kg
The mass of the nitrogen that is being also washed into the river
= 15% of 130 kg
=
= 15 × 1.3 kg
= 19.5 kg /year
Converting kg/year into milligram per seconds; we have:
= 0.61834 mg/seconds
If the river flows at an average rate of 0.460 cubic feet
Let's convert the cubic feet into liters
we all know that;
1 ft = 0.33 meter
1 cubic feet = 28.31 liters
∴ 0.460 cubic feet = 0.460 × 28.31
13.0226 liters
Finally, the additional concentration of nitrogen =
the additional concentration of nitrogen = 0.04748 mg/L
Lyman Series Working Formula:
1/λ = RH (1-(1/n^2))
Given:
n = 6
RH = Rydberg's constant = 1.0968x10^7 m^-1
c = speed of light = 3x10^8 m/s
Required:
Frequency (Hertz or cycles per second)
Solution:
To solve for the wavelength λ, we substitute the given in the working formula
1/λ = RH (1-(1/n^2))
1/λ = 1.0968x10^7 m^-1 (1-(1/6^2))
λ = 0.0000000938 m or 93.8 nm
To get the frequency, we will use the formula below.
f = c/λ
We then substitute c or the speed of light,
f = (3x10^8 m/s) / 0.0000000938 m
Therefore,
f = 3.2x10^15 s^-1
<em>ANSWER: Frequency = </em><em /><em>3.2x10^15 s^-1</em>
Answer:
Synthesis
General Formulas and Concepts:
<u>Chemistry - Reactions</u>
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
Explanation:
<u>Step 1: Define RxN</u>
RxN: NH₃ + H₂SO₄ → (NH₄)₂SO₄
<u>Step 2: Identify</u>
Combining 2 compounds to form 1.
NH₃ + H₂SO₄ → (NH₄)₂SO₄
A + B → AB
<em>It is a Synthesis Reaction.</em>
Hey there!
Mass = 5.6 Kg
Volume =8.2 L
D = m / V
D = 5.6 / 8.2
D = 0.6829 Kg/L
hope this helps!
