They work by neutralizing the stomach acid that causes heartburn. You can buy many antacids without a prescription. Liquid forms work faster, but you may like tablets because they are easy to use.
<span>Errors can come from various sources: the obtainer of the data, the measuring instrument, the setting and etc. Errors are what makes your measurement invalid and unreliable. There are two types of error which is called the systematic error and the random error. Each error has different sources. Words that were mentioned –invalid and unreliable are very important key aspects to determine that your measure is truly accurate and consistent. Some would recommend using the mean method, doing three trials in measuring and getting their mean, in response to this problem.</span>
The conversion factor between moles of calcium ion and moles of 
in would be 3 to 1.
<h3>Mole fraction</h3>
if formed from 3 carbon atoms and 3 phosphate atoms according to the equation:
Thus, there are 3 moles of calcium in every 1 mole of .
The conversion factor between moles of calcium and moles of will. therefore, be 3 to 1 or simply 3:1.

Answer and explanation:
The mole ratio for Mg and MgO would be 2:2 or 1:1 because Mg has 2 as a coefficient and so does MgO, which is why you can simplify the ratio to 1:1
The mole ratio for O and MgO would be 1:2 because O has 1 as the coefficient and MgO has 2 as a coefficient.
