Answer:
partial pressure of gas D Pd = 15.5 kPa
Explanation:
As per the Dalton's law of partial pressure, in a mixture, pressure exerted by each gas when summed gives the total partial pressure exerted by mixture.
P(Total) = P1+P2+P3.....
Given P(Total) = 35.7 kPa
Partial pressure of gas A Pa = 7.8 kPa
Partial pressure of gas B Pb = 3.7 kPa
Partial pressure of gas C Pc = 8.7 kPa
There, Partial pressure of gas D Pd = P(Total) -(Pa+Pb+Pc)
Pd = 35.7-(7.8+3.7+8.7) = 35.7-20.2 kPa = 15.5 kPa
Therefore, partial pressure of gas D Pd = 15.5 kPa
Your answer would be 172.1703 g/ml
Chemicals cancel each other out and produce a salt and water. A neutralization reaction my also occur
<span>In the written directions the indicator that the matter contains protein is when the solution turns a purple color. Therefore we can conclude that if your sample causes the solution of Copper Sulfate and Sodium Hydroxide to turn purple, it does indeed contain protein.</span>
