Answer:
4.15g
Explanation:
Balance the reaction:
2Mg + O2 = 2MgO
Find limiting reactant from the two, by dividing miles with coefficient
2.5/24.3 = 0.103 moles/2 = 0.0515
5/16 = 0.31 moles/2 = 0.156
0.0515 is small than 0.156, so limiting reactant is Mg
Compare the ratio of Mg with MgO
Ratio is 2:2
So same moles = 0.103 moles
Mass = moles x molar mass of MgO
Mass = 0.103 x 40.3
= 4.15g

As a result, the protein molecule is 315 x 10^-9 metres long.
<h3>What does a hydrogen atom contain?</h3>
- The hydrogen atom is the most fundamental of all atoms because it just contains one proton and one electron.
- In addition to this most common isotope, the hydrogen atom can also be found in protium, deuterium, and tritium.
- Hydrogen, denoted by the letter H, has the first atomic number among the lightest elements.
<h3>How do you describe a hydrogen atom?</h3>
- There are three known hydrogen isotopes.
- Hydrogen has isotopes with masses of 1, 2, and 3, with mass 1 being the most common.
- This isotope is also referred to as protium and hydrogen in everyday language (symbol H, or 1H).

Start with the process of elimination. Obviously, color is not a specific component to a wave, so we can cancel that out. While there are frequencies and measurable speeds of waves, those are not considered parts of the wave; nor is the wavelength or the base considered to be a part of the wave. The crest is the highest point of the wave, and is considered a part of the wave, as well as the trough, which is the the lowest point on the wave.
Responder:
27
Explicación:
Dado que:
Número de protones en el átomo X = 29
Carga en el átomo X = +2
Si no hay cargo neto;
número de protones = número de electrones
Sin embargo, dado que el átomo X tiene una carga de +2 (dando 2 electrones).
Por lo tanto,
Número de electrones = número de protones - número de carga en el átomo)
Número de electrones = (29 - 2) = 27
