Answer:
The pressure exerted by gas number 3 is 159 mmHg
Step-by-step explanation:
To answer this question, the law to Use is Dalton’s law of partial pressure
Dalton’s law of partial pressure states that for a mixture of gases which do not mix, the total pressure exerted by such gases is equal to the sum of the individual pressure.
Now for the three gases, the total pressure Pt is equal to P1 + P2 + P3
Now we have Pt = 950 mmHg, P1 = 335 mmHg and P2 = 456 mmHg
P3 = Pt-P1-P2
Plugging the values above, we have ; 950-335-456 = 159 mmHg
Answer:
20
Step-by-step explanation:
Sn = (n/2)(a1 + a1 + d(n-1)), where S = sum, a1 = first term, n = number of terms, d = common difference
400 = (n/2)(1 + 1 + 2(n - 1))
400 = (n/2)(2 + 2n - 2)
400 = (n/2)(2n
400 = n2
20 = n
Twenty numbers are in the set.
Answer:
Make x 0 and y 3
Step-by-step explanation:
0 multiplied by 2 is 0
-3 multiplied by 3 is -9
0-9 = -9
If the number is rounded to 8,920,000 then it can't be over 8,924,999 and it can't be less than 8,915,000.
The numbers in the tens and hundreds are the least and the same. They might be zeros.
The thousands is 2x the ten thousands place. The ten thousands place now is either 2 or 1. The thousands place will either be 2 or 4.
The sum of all the digits is 24. We know that there will be an 8 and a 9 so if we add those up and subtract it from 24, we know the rest of the numbers need to add to 7.
8,924,001 would be your number.
