Oxygen is the correct answer.
Mixtures and solutions... what?
For the answer to the question above,
1∙5µm² = ? m²
1m * 1m = 1m² But 1m = 1,000,000µm = 1x 10^6µm 1x10^6µm * 1x10^6µm = 1m² 1x 10^12µm² = 1m² (Now, try dividing both sides by 1x10^12). 1x10^12µm² /(1x10^12) = 1m² /(1x10^12) 1µm² = 0∙000 000 000 001 m² (multiply both sides by by 1∙5). 1∙5µm² = 0∙000 000 000 0015 m²
1∙5µm² = 1∙5x 10^-12 m²
I hope this helps
from ICE table
H2(g) + I2 (g )↔ 2HI(g)
equ 0.958 0.877 0.02 first mix1
0.621 0.621 0.101 sec mix2
Kp1 = P(HI)^2 / p(H2)*p(I2) for mix 1
= 0.02^2 / 0.958*0.877
= 4.8x10^-4
Kp2 = P(HI)^2 / P(H2)* P(I2) for mix 2
= 0.101^2/ 0.621*0.621
= 0.0265
we can see that Kp1< Kp2 that means that the sec mixture is not at equilibrium. It will go left to reduce its products and increase reactant to reduce the Kp value to achieve equilibrium.
and the partial pressure of Hi when mix 2 reach equilibrium is:
4.8x10^-4 = P(Hi)^2 / (0.621*0.621)
∴ P(Hi) at equilibrium = 0.0136 atm
Answer:
<h2>18 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 2 × 9
We have the final answer as
<h3>18 kg.m/s</h3>
Hope this helps you
