Methane has the alkane functional group, so the name is composed of meth- for the carbon chain, and –ane for the alkane functional group
A .
1 mol of sodium na atoms -22.99
22.99 x 8 =183.92
Closest answer
Mg- is the isoelectronic of Na
No mathematics the most common way of solving an equation will be PEMDAS so the answer for your question will most likely be subtraction.
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
