<u>Answer:</u> The mass percent of silicon in the given compound is 15.9 %
<u>Explanation:</u>
We are given:
A chemical compound having chemical formula
To calculate the percent by mass of silicon in given compound, we use the equation:
Mass of silicon =
Mass of compound =
Putting values in above equation, we get:
Hence, the mass percent of silicon in the given compound is 15.9 %
<span>C-C and C-H bonds are relatively stable because

Hope this answers the question. Have a nice day.</span>
Molarity = number of moles/Volume (L). Solve for the number of moles in the initial solution (3.78M = n/0.3 L) and then use that amount of moles and the new volume (0.5 L) to solve for the new Molarity.
When lights hits an object, the light either get absorbed, reflected or refracted
Answer:
electrons
The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus. The electrons have a negative electrical charge
