Complete and Balance each gas-evolution equation.

Question

wmj259 · Answer

$$HBr(aq)+Ni(s) \rightarrow$$

wmj259 · Answer

My attempt was that
$$H _{2}S (g) + NiB(aq)$$

wmj259 · Answer

Not sure if thats right.

wmj259 · Answer

Apparently sulfides don't have an intermediate product so it turns into a "gas".

Well you have to know different kinds of reactions and balancing rules.

korosh23 · Answer

Now we are involved with single replacement and double replacement reactions. https://www.youtube.com/watch?v=qhmTXdOKTBo Single replacement reaction is a reaction in which one element replaces another element in a compound ! Double replacement reaction is a reaction when two elements in different compounds replace each other! After learning these two replacement reactions we get to reactivity series which usually is included in some periodic tables. If not in yours then check this out! http://www.edplace.com/userfiles/image/Reactivity%20Series%20ADDED.jpg More reactive replaces less reactive. However, less reactive cannot replace higher reactive elements. You only have to know these series for single replacement reaction not double rep reaction. Ask your teacher and I am sure he will give it to you. Now balancing needs practicing a lot. http://misterguch.brinkster.net/eqn1.jpg This is a good way for beginning.
