Answer:

PART A: 412.98 nm

PART B: 524.92 nm

Explanation:

The equation below can be used for a diffraction grating of nth order image:

n*λ = d*sinθ $_{n}$

Therefore, for first order images, n = 1 and:

λ = d*sinθ $_{1}$ .

The angle θ $_{1}$ can be calculated as follow:

tan θ $_{1}$ = 9.95 cm/15.0 cm = 0.663 and

θ $_{1}$ = $tan^{-1}$ (0.663) = 33.56°

Thus: d =λ/sin θ $_{1}$ = 461/sin 33.56° = 833.97 nm

PART A:

For a position of 8.55 cm:

tan θ $_{1}$ = 8.55 cm/15.0 cm = 0.57 and

θ $_{1}$ = $tan^{-1}$ (0.57) = 29.68°

Therefore:

λ =d*sin θ $_{1}$ = 833.97*sin 29.68° = 412.98 nm

PART B:

For a position of 12.15 cm:

tan θ $_{1}$ = 12.15 cm/15.0 cm = 0.81 and

θ $_{1}$ = $tan^{-1}$ (0.81) = 39.01°

Therefore:

λ =d*sin θ $_{1}$ = 833.97*sin 39.01° = 524.92 nm

According to your study unit, what's the payoff that keeps volunteers using their own time to help their communities?

klasskru [66]

C. It's so rewarding, people feel emotionally high and fulfilled when they're done.

In volunteering, your primary motivation is to extend your help or assistance and make other people happy. Seeing people happy because of what you are doing, it the ultimate reward of volunteering. Happiness gained from this experience is priceless. It is worth more than any freebies or any material gains you will receive.

Consider the above unbalanced equation. What volume of CO2 is produced at 270. mm Hg and 38.5°C when 0.820 g of C4H8 reacts with

irinina [24]

Answer:

The volume of CO2 is 4.20 L

Explanation:

Step 1: Data given

Pressure = 270 mm Hg = 260 /760 = 0.355263 atm

Temperature : 38.5 °C = 311.65 K

Mass of C4H8 = 0.820 grams

Step 2: The balanced equation

C4H8 + 6O2 → 4CO2 + 4H2O

Step 3: Calculate moles C4H8

Moles C4H8 = mass C4H8 / molar mass C4H8

Moles C4H8 = 0.820 grams / 56.11 g/mol

Moles C4H8 = 0.0146 moles

Step 4: Caalculate moles CO2

For 1 mol C4H8 we need 6 moles O2 to produce 4 moles CO2 and 4 moles H2O

For 0.0146 moles we'll have 4*0.0146 = 0.0584 moles CO2

Step 6: Calculate Volume CO2

p*V = n*R*T

V = (n*R*T) /p

⇒ with V = the volume of CO2 = TO BE DETERMINED

⇒ with n = the moles of CO2 = 0.0584 moles

⇒ with R = the gas constant = 0.08206 L*atm / mol*K

⇒ with T = The temperature = 311.65 K

⇒ with p = the pressure = 0.355263 atm

V = (0.0584 * 0.08206 * 311.65) / 0.355263

V = 4.20 L

The volume of CO2 is 4.20 L
