Answer:
42%
Step-by-step explanation:
To find the percent of decrease first find the difference between 32.25 and 18.70.
32.25 - 18.70 = 13.55
Now divide this number by the original number, in this case 32.25, and then multiply the answer you get by 100.
13.55 / 32.25 = 0.42
Multiply this number by 100 to get the percentage.
0.42 * 100 = 42
Answer:
See answer below
Step-by-step explanation:
the ratio of pv against nrt is called compressibility Z and measures the deviation from an ideal gas behaviour . When Z is plotted against pressure for CH₄ for 0°C and 200°C the curves will differ because there are
- negative deviations ( Z decreases) due to intermolecular forces
- positive deviations (Z increases ) due to molecular size of gas particles
then
- at 0°C the negative deviations prevail respect to positive deviations at lower pressures ( so Z drops below the horizontal line first ) and then Z increases when pressure increases since the effect of positive deviation is higher ( then Z increases)
- Nevertheless, at 200°C the effect of intermolecular forces is lower and thus the positive deviations always prevail ( thus you observe only Z increasing(
-7(-1-m)
First: You would distribute your -7 to your -1 and your -m
Note: A positive and a positive makes a negative.
You would get: 7m+7 as your answer

Answer: x equals 174
Step-by-step explanation: This looks like a parallelogram and if it is then the side opposite 157 would also be 157 so u just had to add 17 to 157 and thats ur answer of 174.
