# Help with writing a chem equation

I need to write a balanced equation for a reaction between water solutions of nitric acid and magnesium hydroxide. I'm stuck and I'm sorry I don't know how to type in subscripts, so I can't write out the formula on here.

Any help?

I think that's just an acid/base reaction.

I know it's an acid base reeaction but I need to know the products.

Let's check what you need carefully:

You want to know how to put in the subscripts; you should learn to use TexAid, or something else that others might recommend. TexAid is freeware, and it is very easy to learn to use. You can paste from the editor into your forum message, and insert tags into the message around your expressions. Those tags would be [ t e x ] and [ / t e x ], but without the spaces.

Now about your question of the products; as ShawnD has stated, this is an acid-base reaction. What are the products of the reaction of an acid with a base? Salt and water. Balance accordingly.

$$$Mg(OH)_2 + 2HNO_3 \to Mg(NO)_2 + 2HOH$$$

The code between the tags is: $Mg(OH)_2 + 2HNO_3 \to Mg(NO)_2 + 2HOH$

I made a little (important) mistake there. Reaction should be:

$$$Mg(OH)_2 + 2HNO_3 \to Mg(NO_3 )_2 + 2HOH$$$

Remember, acid+base reactions always yield a salt, and water.

So you get Sodium Nitrate and Water.
