Answer:
140.32mL per hour
Step-by-step explanation:
Rate of leakage of nitrogen ballon = 75 mL/h
Rate of leakage of helium ballon = x
Molar mass of nitrogen= Mn = 14
Molar mass of helium = Mh = 4
Effusion formula
Rate of effusion of helium/ Rate of effusion of nitrogen= √(Molar mass of nitrogen/Molar mass of helium)
Rate of effusion of helium = 75mL/h * √(14/4)
= 140.32mL/h
C) -5,-2,1,4,6 is the correct answer
There would only be on answer as this is not a quadratic equation. Please mark Brainliest!!!
Answer:
D. Yes, since the slopes are the same and the y-intercepts are different.
Step-by-step explanation:
yes because both line have a slope of .857/2
...................................................................................................................................................
yes; both have a slope of 3/7
...................................................................................................................................................
Yes. They have the same slope.
<u>angle B and angle G</u> are congruent because of the alternate exterior angles theorem.
<u>angle A and angle H</u> are also congruent, because of the same theorem.
So, the answers are <u>A, and D</u>
