The answer is (4) 4. Germanium is a main group element in group 4A. Therefore, like carbon, it has 4 valence electrons in the ground state.
I think this the the list of choices relating to the above question.

The term that best relate to ben's observation is REACTION RATE.
Reaction rate is defined as the speed at which the chemical reaction proceeds. It either is the amount of concentration of a product in a given unit of time or the concentration of the reactant that is being consumed in a unit of time.
Answer:
The advantage of this technique is that purified water as well as deposited metals can be re-used. It is necessary to use an inert electrode, such as platinum, because there is no metal present to conduct the electrons from the anode to the cathode.
The reaction between hydrogen and oxygen to form water is given as:
![H_2 + O_2 \rightarrow H_2O](https://tex.z-dn.net/?f=H_2%20%2B%20O_2%20%5Crightarrow%20H_2O)
The balanced reaction is:
![2H_2 + O_2 \rightarrow 2H_2O](https://tex.z-dn.net/?f=2H_2%20%2B%20O_2%20%5Crightarrow%202H_2O)
According to the balanced reaction,
4 g of hydrogen (
) reacts with 32 g of oxygen (
).
So, oxygen reacted with 29.4 g of hydrogen is:
![\frac{29.4\times 32}{4} = 235.2 g](https://tex.z-dn.net/?f=%5Cfrac%7B29.4%5Ctimes%2032%7D%7B4%7D%20%3D%20235.2%20g)
Hence, the mass of oxygen that is reacted with 29.4 g of hydrogen is 235.2 g.
