Answer:

a. the covalent and ionic bonds that hold elements and compounds together are broken and new bonds are formed

Explanation:

A chemical reaction is a process by which one or more substances, called reactants, are transformed into other substances with different properties, called products.

In a chemical reaction, the covalent and ionic bonds between the atoms that make up the reactants are broken. Then, the atoms rearrange themselves in another way, forming new bonds and giving rise to one or more different substances from the initial ones.

Maalox is the trade name for an antacid and antigas medication used for relief of heartburn, bloating, and acid indigestion in which

4 ml contains

= 320mg of aluminum hydroxide

= 320mg of magnesium hydroxide

= 32mg of simethicone

recommended doses = 4 times * 2 tea spoon = 8 tea spoon/ day

given = 1 tea spoon = 5 ml

8 tea spoon = 40 ml

hence,

amount of aluminum hydroxide = 320/4 * 40 = 3200mg = 3.2 g

amount of magnesium hydroxide = 320/4 * 40 = 3.2 g

amount of  simethicone = 32/4 * 40 = 320 mg = 0.32g

How do I balance this equation? ?KNO3 → ?K2O + ?N2(g)+ ?O2(g) and what type of reaction is it?
nirvana33 [79]

Answer:

4KNO3 ==> 2K2O + 2N2 + 5O2

Explanation:

It's a decomposition, but not a simple one.

KNO3 ==> K2O + N2 + O2   I don't usually do this, but I think the easiest way to proceed is to  balancing the K and N together. That will require a 2 in front of KNO3

4KNO3 ==> 2K2O + 2N2 + 5O2

Now you have (3*4) = 12 oxygens. Two are on the K2O. So the other 10 must be on the O2

That should do it.
