Answer: 7.81 mol HgO (How many moles of mercury(II) oxide, HgO, are needed to produce 125 g of oxygen, O2?)
Explanation:
Answer:
Explanation:
Reactants
Magnesium = 24.3 g
Hydrogen chloride= x g
Products
Hydrogen gas = 2.04 g
Magnesium chloride = 96.9 g
As the mass of the reactions is conserved we have
Mass of reactants = Mass of products
Mass of hydrogen chloride is .
Answer:
Deshydrohalogenation
Explanation:
You are not providing options to answer, however, this can be answered without options.
Now, in the reaction we can see that we have an atom of Bromine in carbon 2, and in the product appears as NaBr. This means that the Br was substracted by elimination. It's an elimination because the final product do not have a substituent where the bromine was, (Like another nucleophyle such OH or another halide). If you look closely the final product, we can see that one hydrogen in carbon 3, is no longer there. So this electrophyle was also substracted, in this case, by a base (Such NaOH), so in this case, it's ocurring an elimination reaction via E2 (One step, bimolecular). So, as the final product has been substracted the nucleophyle and electrophyle, this treaction is a deshydrohalogenation (an atom of hydrogen and a halide were substracted). The mechanism of this, you can see it in the picture.
Answer:
ions
Explanation:
if you have telekinesis and you move a pencil the ions are the ones moving it the ions that are in our bodies are different with the ones in the air that's why sometimes when it rains some of us get sick it's because the ions that are in the air enter into our bodies
Answer:
RbCl
Step-by-step explanation:
Rb is in Group 1. It can <em>lose one electron</em> to get a complete shell.
Cl is in Group 17. It can get a complete shell by <em>gaining one election</em>.
Thus, one Rb atom can react with one Cl atom.
The formula of rubidium chloride is RbCl.
