Vapor pressure is a criteria for a substance's volatility. This is the ability of a substance to transition from liquid to vapor. When the vapor pressure equals the external pressure, liquid turns to gas. Hence, if the substance has higher vapor pressure, then it is volatile. <em>Therefore, Sample A is more volatile than Sample B.</em>

For a specific enzyme/substrate system, which condition will always result in an increase in Vo (assuming nothing else changes)?
inessss [21]
<span>a decrease in Km and an increase in Vmax
 km is the constant that relates how thick the volume of the substrate in terms of concentration when the speed is a large portion of the most extreme. They increment Km by meddling with the joining process that makes them stick together wit the substrate, however they have any effect with regards to Vmax since since the sticking process to ES did not occur</span>

What is the energy of a photon with a frequency of 9.50 x 1013 Hz?
Taya2010 [7]

Answer:

\huge{6.295 \times  {10}^{ - 20}  \: J}

Explanation:

The energy of the photon can be found by using the formula

E = hf

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question we have

E = 6.626 × 10-³⁴ × 9.5 × 10¹³

We have the final answer as

6.295 \times  {10}^{  - 20}  \: J

Hope this helps you
