Answer

Vr = 0.5mol / s

Explanation

To calculate the reaction rate we have to divide the amount of substance consumed and the time it was consumed.

Vr = mol / t = 1.5moles / 3s

Vr = 0.5mol / s

The rate of reaction is 0.050 mol·s⁻¹.

For the reaction

P_4 + 5O_2 \longrightarrow P_4O_{10}\\

\text{rate} = \frac{\Delta P_4O_{10} }{\Delta t } = \frac{\text{1.5 mol }}{\text{ 30 s }} = \text{0.050 mol}\cdot \text{s}^{-1}\\

vesna_86 [32]
Since 1mL=1cm^3 the wood would sink due to it being more dense. I.e. 0.95>0.88

Answer:

n=2.59\times 10^{16} photons

Explanation:

E=n\times \frac{h\times c}{\lambda}

Where,  

n is the number of photons

h is Plank's constant having value 6.626\times 10^{-34}\ Js

c is the speed of light having value 3\times 10^8\ m/s

\lambda is the wavelength of the light

Given that, wavelength = 514 nm = 514\times 10^{-9}\ m

Energy = 10.0 mJ = 0.01 J ( 1 mJ = 0.001 J )

Applying the values as:-

0.01=n\times \frac{6.626\times 10^{-34}\times 3\times 10^8}{514\times 10^{-9}}

\frac{19.878n}{10^{17}\times \:514}=0.01

n=2.59\times 10^{16} photons
