<u>Answer:</u> The partial pressure of hydrogen is 705.9 mmHg
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of hydrogen gas, we use the law given by Dalton, which is:
We are given:
Total pressure of the collection tube, = 729.8 mmHg
Vapor pressure of water, = 23.8 mmHg
Putting values in above equation, we get:
Hence, the partial pressure of hydrogen is 705.9 mmHg
The answer would be, B, Nuclear energy stored in the oceans has a major effect on Earth's weather and climate
Answer:
Explanation:
Hello,
In this case, the relationship between the mass, heat, temperature and heat capacity id given by:
In such a way, the temperature change results:
Clearly it is a positive change which means the temperature increases as heat is added.
Regards.
Answer:
B. N, O, F
Explanation:
Elements in same row of periodic table will have same number of orbitals.
In option A C and D elements are of different row due to which they posses different number of orbitals.
But in option B. N, O, F are in second row of periodic table so same orbitals.
I would say that there is 270 grams left. since its F2 you have three things there.
divide 405 by 3
you will get 135.
but there are 2 F's so multiply that by 2 and you will get 270.
the final answer should be 270 grams left.
