The answer is 2 because you have to divide these numbers.<span />
<h3>
Answer:</h3>
15 moles
<h3>
Explanation:</h3>
The decomposition of boron carbonate is given by the equation;
B₂(CO₃)₃(s) → B₂O₃(s) + 3CO₂(g)
Moles of boron carbonate decomposed is 5.0 mol
To find the moles of CO₂ produced we are going to use the mole ratio.
Mole ratio of B₂(CO₃)₃ to CO₂ is 1 : 3
Therefore;
Moles of CO₂ = Moles of B₂(CO₃)₃ × 3
= 15 mol
Therefore, 15 moles of CO₂ will be produced
If they didn't, they wouldn't be able to communicate their findings effectively. An international language is especially important for elements because many elements have similar properties (e.g. some of the transition metals).
Answer:
a. What is the wavelength?
The wavelength is 5 meters.
b. What is the frequency?
The frequency is 0.05Hz
c. What is the wave velocity?
The wave velocity is 0.25 meters per second
Explanation:
the wavelength is the distance between two troughs or two crests, which in this case is 5 meters.
the frequency=cycles/time. For this equation the equation would be 1/20, which is 0.05
the wave velocity=wavelength x frequency. Plug in the numbers, 5 x 0.05, and you will get 0.25.
