If the burning of magnesium to form magnesium oxide is incomplete, there will still br some elemental magnesium available to be burned (ie combined with oxygen) and so there will be a measureable amount of mass of magnesium left. Also, the amount of oxygen required to combine with the outstanding mass of magnesium could also be determined.
Answer:
A major characteristic of mixtures is that the materials do not chemically combine
Explanation:
Mixtures can be divided into those that are evenly distributed (homogeneous) and those that aren't (heterogeneous)
His group's cube was made of <span>D) zinc. Looking up the density values of each of the choices, it can be seen that zinc has the closest density out of all of them. It's actual density has a value of 7.14 g/cm3. The others have density values that are way too far from the average density of 7.4 g/cm3.</span>
Answer:
<h2>8</h2>
Explanation:
The pH of a solution can be found by using the formula
![pH = - log [ {H}^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20%7BH%7D%5E%7B%2B%7D%20%5D)
From the question we have
We have the final answer as
<h3>8 </h3>
