I suppose because of the fact that the relative humidity is taking away your heat and making you feel cool, I think that you would feel cooler than someone who was dry.

- <em>A skeleton equation shows just the reactants and products whereas a balanced equation shows the</em><u> relative amounts of, or proportion between, reactants and products.</u>
Explanation:
The <em>skeleton equation</em> shows which <em>reactants </em>are being used and which <em>products </em>are being formed.
The reactants are shown on the left and the products are shown on the right side of the equations, separeted by an arrow.
For example, the skeleton equation to obtain water is:
From it you know that hydrogen and oxygen react to form water, yet you do not know in which ratio they do it.
Then, you balance the equation, adding the appropiate coefficients, to make the number of atoms of each kind on the reactant side equal to the number of the same kind of atoms on the product side.
This is, for the example of water, the number of hydrogen atoms on the left must equal the number of atoms of hygrogen on the right side, and the number of oxygen atoms of the left must equal the number of oxygen atoms on the right.
For the water example that is:
- 2H₂(g) + O₂(g) → 2H₂O (g)
- Showing that 2 molecuies of hydrogen (or 4 atoms) react with 1 molecule of oxygen (or 2 atoms) to produce 2 molecules of water, and that proportion (relative amounts) will always be true for that reaction.
Answer:
The first kind of body wave is the P wave or primary wave.
Explanation:
This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station.
Answer:
The answer to your question is 308.1 kPa
Explanation:
Data
Volume 1 = V1 = 4.75 l
Pressure 1 = P1 = 120 kPa
Volume 2 = V2 = 1.85 l
Pressure 2 = ?
Process
To solve this problem use Boyle's law.
P1V1 = P2V2
- Solve for P2
P2 = P1V1 / V2
- Substitution
P2 = (120 x 4.75) / 1.85
-Simplification
P2 = 570 / 1.85
-Result
P2 = 308.1 kPa
To solve this question, we first need to know the mass of one mole of mercury. This can be done by checking the periodic table.
From the periodic table, we can see that:
molar mass of mercury = 200.59 grams/mole.
From the measurements, the chemist found that the participated amount of mercury is 0.02 moles.
We can simply determine the mass of 0.02 moles by doing cross multiplication as follows:
mass of 0.02 moles = (0.02 x 200.59) / 1 = 4.0118 grams
Rounding the answer to 2 significant digits, we get:
mass of 0.02 moles = 4.01 grams
