I’m thinking it would be c sorry if it’s wrong .
Answer: To detect and correct errors, additional bits are added to the data bits at the time of transmission. The additional bits are called parity bits. They allow detection or correction of errors. The data bits along with the parity bits form a code word.
Explanation:
Answer:
0.07973 moles of O2 gas were produced
2.66 atm
Explanation:
Using the ideal gas equation
PV =nRT
P =pressure = 2.9 atm
V= volume = 720 mL = 720mL/1000= 0.72 L
n = number of moles = ?
R = the gas constant = 0.0821 atm L/(mol K)
T = temperature in Kelvin = 319 K
make n subject of the formula
n =PV/RT
n = 2.9 atm x 0.72 L / 0.0821 atm L/(mol K) x 319K = 0.07973 moles of O2 gas were produced
Pnew = atm?
P = nRT/V
= 0.07973 x 0.0821 atm L/(mol K) x 293K/0.72 L = 2.66 atm
This would be answer choice D: all of the above. Low back pain can be classified by duration as acute (pain lasting less than 6 weeks), sub-chronic (6 to 12 weeks), or chronic (more than 12 weeks).
