Answer:So, the prime factors of 90 are 2 × 3 × 3 × 5 or 2 × 32 × 5, where 2, 3 and 5 are the prime numbers.
Step-by-step explanation:
Answer:
A - PV/RT = n
Step-by-step explanation:
The objective is to isolate the variable n which represents moles. To do so, you must get rid of the surrounding variables.
Surrounding n, the variables R (gas constant) and T (temperature) are shown being multiplied with n. To get rid of them, you must do the inverse which is to divide.
PV = nRT
Divide both sides by R
PV/R =nT
Divide both sides by T
PV/RT = n
And now, the variable n has been isolated and the new equation to solve for moles is presented.
Hope this helps!
Answer:
you're correct it's scale factor
Yes because 235 never needs to be in 3square
The answer is C Becase all rationals are positive so to get the answer make them negative so c is the answer
