Answer:
Hi, I think the D since the moon rotates about once a month and these months have different amounts of days. an example would be February that can have like 28 or 29 in leap year
Explanation:
Answer:
Single displacement reaction
Explanation:
2AI + 6HCI —> 2AlCl3 + 3H2
From the above reaction, we see clearly that Al displaces H from HCl. This is clearly a single displacement reaction.
Any organism in motion possesses kinetic energy. Kinetic energy is the energy the body has while in motion.
<u>Answer:</u> The nuclear binding energy of the given element is
<u>Explanation:</u>
For the given element
Number of protons = 3
Number of neutrons = (6 - 3) = 3
We are given:
M = mass of nucleus =
Calculating mass defect of the nucleus:
Converting this quantity into kg/mol, we use the conversion factor:
1 kg = 1000 g
So,
To calculate the nuclear binding energy, we use Einstein equation, which is:
where,
E = Nuclear binding energy = ? J/mol
= Mass defect =
c = Speed of light =
Putting values in above equation, we get:
Hence, the nuclear binding energy of the given element is
Answer:
Solution 1.
Explanation:
We can find the concentration of a solution by looking at the ratio of the components.
In the first solution, there is a 500 mL:100g ratio. In the second, there is a 500mL:90g ratio. The greater ratio, or the ratio with a greater amount of solute in proportion to the water, is the first.
