Answer:
True
Explanation:
Because atoms with the same number of valence electrons react in similar ways with other elements.
Answer:
1) 2-bromobutane
2) 1-bromobutane
Explanation:
In the HBr reaction, we will have a <u>markovniknov reaction</u> due to the <u>carbocation formation</u>. The Br- then would be added in the <u>most substituted</u> carbon of the double bond.
In the HBr/peroxide reaction we have the opposite case: an <u>anti-markovnikov reaction</u>. Therefore the Br- would be added in the <u>least substitued</u> carbon of the double bond.
Answer:
CO
Explanation:
Co, Cr, and Cu are elements. Elements cannot be broken down by a chemical change, but compounds can. and CO is a compound
I think It means that any balanced equation is conserved. Meaning that the equation is equal. The law states matter can’t be created or destroyed. In chemical reactions the mass of an element is the same before and after the product. There’s two sides two an equation the reactants side and the product’s side. Hope this helps.
Answer:
No limiting reagent. There is an exact amount of each.
Explanation:
Start by getting the equation
Fe + O2 -> Fe2O3
If you balance the oxygens the Fe will easily follow.
Fe + 3O2 => 2Fe2O3
So far what you have is 6 oxygens on the right and 6 on the left. Now all you need do is balance the irons. The are 4 on the right (2Fe2). So you must have 4 on the left.
4Fe + 3O2 -> 2Fe2O3
Now to your question if you have 4 mols of iron, you need 3 mols of O2. Those are the balance numbers of the equation. They also represent mols.
There is no limiting reagent in the theoretical world of chemistry. All the iron will be used up and so will the given amount of oxygen.
