Answer:
2 Fe + 3 Br₂ → 2 FeBr₃
Explanation:
There are 2 Br atoms on the left, and 3 on the right. So put a 3 in front of Br₂, and a 2 in front of FeBr₃.
_Fe + 3 Br₂ → 2 FeBr₃
Now there's 6 Br atoms on each side. There are 2 Fe atoms on the right side, so put a 2 in front of Fe:
2 Fe + 3 Br₂ → 2 FeBr₃
Now the equation is balanced.
Answer:
During an experiment, a student moves a cell from pure water to salted water. ... It will release water and shrivel. It will release water and burst.
The answer is c
Explanation:
Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit.
Answer:
Speed = 300 m/s
Explanation:
Given the following data;
Frequency = 150 Hz
Wavelength = 2 meters
To find the speed of the wave;
Mathematically, the speed of a wave is given by the formula:
Substituting into the formula, we have;
Speed = 300 m/s
