Na = +1
H = +1
O = -2
Total charge is 0:
1 + 1 + C + 3 x -2 = 0
C = 4
<span>Because it has very weak intermolecular meaning it takes little energy to break them and turn it into a gas</span>
A amplitude = 0.50 m and wave-length = 1.0 m
B amplitude = 0.40 m and wave-length = 2.0 m
C amplitude = 0.60 m and wave-length = 2.0 m
Answer:
By placing the steel wool in a jar with plenty of oxygen and water, you start a chemical reaction. The iron and the oxygen react to form a new reddish-brown substance, called iron oxide or rust. In this experiment, the water level in the glass should rise as the oxygen inside combines with the iron in the steel wool.
Explanation:
Answer:
which formula can be used to calculate the molar mass of hydrogen peroxide (H2O2)?
» <u>d.2 x molar mass of H + 2 x molar mass of O</u>
Explanation:
Since we've two hydrogen atoms and two oxygen atoms, we multiply each mass by 2
Which of the following statements best defines the actual yield of a reaction?
»<u> </u><u>d.The ratio of measured yield over stoichiometric yield</u>
