Aww man, I love these types of problems!!!
So, it's a simple formula:
P1*V1/T1=P2*V2/T2
In this case, we remove V(volume) as there is none listed, leaving this:
P1/T1=P2=T2
Think you got it from here? All you gotta do is plug in the numbers and solve
If you have any further problems, just let me know!!
Answer:
P(N) = 38.48 mmHg
Explanation:
Given data:
Partial pressure of He = 15.22 mmHg
Partial pressure of O = 35.21 mmHg
Partial pressure of N = ?
Total pressure = 88.91 mmHg
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Now we will solve this problem by using this law.
P(total) = P(He) + P(O) + P(N)
88.91 mmHg = 15.22 mmHg + 35.21 mmHg + P(N)
88.91 mmHg = 50.43 mmHg + P(N)
P(N) = 88.91 mmHg - 50.43 mmHg
P(N) = 38.48 mmHg
Answer:
63.616
Explanation:
DATA
1. first atomic mass;m1=63
- second atomic mass;m2=65
- first percentage;p1= 69.2%
- second percentage me;p2=30.8%
- average mass;avg= ?
SOLUTION
avg=<u> (m1)(p1) + (m2)(</u><u>p2</u><u>)</u>
100
avg= <u>(63)(69.2) + (65)(30.8)</u>
100
avg= <u>4</u><u>3</u><u>5</u><u>9</u><u>.</u><u>6</u><u> </u><u>+</u><u> </u><u>2</u><u>0</u><u>0</u><u>2</u>
100
avg= <u>6361.6</u>
100
avg= 63.616
Answer:
An Element
Explanation:
An Element is made up of only one type of atom (Gold, Silver, etc.)
Hope this helps!
Waters high heat capacity is a property focused by hydrogen bonding among water molecules.When heat is absorbed,hydrogen bonds are broken and water molecules can move freely.When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy
