The solution would be like
this for this specific problem:
<span>1.0
</span>atm + 2.0 atm
+ 3.0 atm = 6.0 atm
So the partial pressure of
the helium 3.0 atm.
<span>I hope this helps and if you
have any further questions, please don’t hesitate to ask again.</span>
B. All atoms have a dense central core called the atomic nucleus. Forming the nucleus are two kinds of particles:protons, which have a positiveelectrical charge, and neutrons, which have no charge. All atoms have at least one proton in their core, and thenumber of protons determines which kind of element an atom is.
C. Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P." Neutrons have no electrical charge.
Answer:
Explanation:
The first step is the <u>calculation of the moles</u> of and , so:
Now, in 1 mol of CO2 we have 1 mol of C and in 1 mol of we have 1 mol of H. Additionally, if we want to calculate the moles of oxygen we need to <u>calculate the grams of C and O</u> and then do the <u>substraction</u> form the initial amount, so:
Now we can <u>convert the grams</u> of O to moles, so:
The next step is to divide all the mol values by the <u>smallest one</u>:
Therefore the formula is
Answer:
1. If you put a bucket of water out in the Sun on a hot, windy day, what will happen to the water level in the bucket? The water level will stay the same since the water is protected from the wind. The water level will only go down if the wind makes water splash out of the bucket
Explanation:
Answer:
In this regard, is the nucleus positively or negatively charged? The nucleus, that dense central core of the atom, contains both protons and neutrons. Electrons are outside the nucleus in energy levels. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
