Answer:
Explanation:
25.3% Mg
74.7% Cl
First step: change % to g
25.3g Mg
74.7g Cl
Second step: calculate g/mol of each compound. You can do this by using the atomic mass.
Third step: determine the lowest number and divide everything by it. Of the result, extract whole number only.
Fourth step: Write each compound with their respective number below.
This empirical formula should be:
The active site of the enzyme.
In 2021 the James Webb Telescope will begin operation focusing on infrared wavelengths and must be kept extremely cold.
<h3>What is James Webb Telescope?</h3>
The James Webb Telescope is the most important optical telescope present in space, which is employed by astronomers to observe celestial bodies and physical phenomena in the universe.
This space telescope (James Webb Telescope) is based on the infrared wavelengths that cover a specific length of 0.57 to 28-micrometer waves and enable to observe different spectra across the Universe.
In conclusion, in 2021 the James Webb Telescope will begin operation focusing on infrared wavelengths and must be kept extremely cold.

Answer:
76 protons 76 electrons
Explanation:
The atomic number in a element is equal to the elements protons and electrons. In this case if the atomic number is 76 the number of protons and electrons would also be 76.
Hope this helps.
