Answer:
eight strong bonds to the atoms that it touches and six weaker bonds to the atoms it almost touches. This makes it easier to understand why a metal might prefer the body-centered cubic structure to the hexagonal or cubic closest-packed structure.
Explanation:
2H2O2 => 2H2O + O2
Moles of hydrogen peroxide = 0.150dm³ * (0.02mol/dm³) = 0.003mol .
Moles of oxygen = 0.0015mol.
Volume of oxygen = 0.0015mol * (22.4dm³/mol) = 0.0336dm³.
Since the reaction gives off heat energy it is considered to be an exothermic reaction
Answer:
335,000,000,000,000 Hz
Explanation:
3.35 x 10^14 is just scientific notation. This is a way to make a really big number small to write and easier to understand. The exponent on the 10 represents how many times you move the decimal to the right. If the exponent is negative you should move the decimal to the left. Each time the decimal is moved, and there is no pre-existing number, you need to add a zero.
3.35 x 10^14 is equal to
335,000,000,000,000
