Answer:
The answer to your question is 27.3 %
Explanation:
Percent by mass = ?
Process
1.- Calculate the atomic mass of carbon using the periodic table
Atomic mass = 12g
2.- Calculate the molecular mass of CO₂.
Carbon = 12
Oxygen = 16 x 2 = 32
Total = 12 + 32 = 44g
3.- Calculate the percent by mass of carbon using proportions
44g -------------------- 100%
12 g ------------------- x
x = (12 x 100) / 44
x = 1200 / 44
x = 27.3 %
Because the block of wood is more bigger and thicker
Answer:
.926 moles
Explanation:
Rounding :
H2 0 = 18 gm/mole
50 gm would then be 50 / 18 = 2.7777 moles of water
every two moles of 2 C6H6 produces 6 moles of water
2.7777/6 * 2 = .926 moles
Metalloids share many similar properties including: They appear to be metal in appearance, but are brittle. They can generally form alloys with metals. Some metalloids such as silicon and germanium become electrical conductors under special conditions. Mark me brainliest please
I believe the correct answer from the choices listed above is the second option. The chemical energy of the log compare to the heat and light energy it is transformed into would be the <span>amount of chemical energy is less than the amount of heat and light energy. </span>
