Answer:
In order for people to survive, we need water. If we wanted to live on the moon, we would need water.
It won't be possible for me to answer this question if there is no context. I tried to find a similar question and I came up with one. The problem is shown in the attached picture. From the given choices, all their units are atm*mL. So, that means that P*V. The answer could only be (2) or (4). Let's try the data in the table to find out.
PV = (0.5 atm)(1000 mL) = 500 atm*mL
PV = (1 atm)(500 mL) = 500 atm*mL
PV = (2 atm)(250 mL) = 500 atm*mL

<em>Thus, the answer is choice (2).</em>
Answer:
8.31moles of H2O
Explanation:
Avogadro's hypothesis gives us an excellent understanding that 1mole of any substance contains 6.02x10^23 molecules. This means that 1mole H2O also contains 6.02x10^23 molecules.
Now, if 1 mole of H2O contains 6.02x10^23 molecules
Therefore, Xmol of H2O will contain 5.00x10^24 molecules i.e
Xmol of H2O = (5.00x10^24)/6.02x10^23 = 8.31moles of H2O
Light is one form of energy that travels in electromagnetic waves. This energy is both magnetic and electrical. There are many different types of electromagnetic (EM) waves.
Answer:
A.
Explanation:
The β-sheet is a twisted pattern in which the protein strands are laterally linked through hydrogen bonds. These β-sheet motifs are segments of 3 to 10 amino acids that are specially configured to form beta antiparallel strands. In β-sheet regions, the hydrogen bonds are localized among carbonyl and amino groups of the polypeptide backbone, and side chains (i.e., the R groups) are extended up and down in the plane of the β-sheet.
