The empirical formula of the compound is determined by converting the individual masses of each element to moles first. Hence for Mg, this is equal to 0.2042 moles, and oxygen is equal to 0.2 moles. We divide the number of moles to the smaller value between the two. For Mg, that is 1 as well as for oxygen. Hence the answer is MgO or magnesium oxide.
Answer:
To convert a decimal into scientific notation, move the decimal point until you get to the left of the first non-zero integer. The number of places the decimal point moves is the power of the exponent, because each movement represents a "power of 10".
<span>The function of a hypothesis is to create a testable statement. In that, a hypothesis can be followed up by a experiment. Hypotheses can be used in order to determine if there is a result of an affect, this is the independent variable, what you get out is the dependent variable, or the result. There is a control that is used generally as a means to test your hypothesis to a standard.</span>
Hi there!
All gasses and engines need fuel to burn because the heat or chemical reaction from the burning fuels are converted into different types of energy that fuel (or help fuel) the engine or gas.
Hope this helps!
