How many Mg atoms are found in 1.00 mole of MgO?

Chemistry
1 answer:
ipn [44]3 years ago
7 0

Answer:

From the equation above we get 1 amu = 1g/NA or 1 amu = 1.66054x10^-24 g. Thus, a mole of magnesium atoms has a mass of NA x 24.305 amu x (1.66054x10^-24 g/amu) = 24.305 g. A mole of magnesium atoms has a mass of 24.305 g.

borishaifa [10]
<span>The reason why it is easiest to assume the first step is slow is because that would be your rate determining step and would give you the rate law given in the problem. So you take the two compounds from the rate law given and put them as your two reactants in your first step: NO2 + F2 ---> NO2F + F (all gases) Your next step needs to make sense for your overall reaction. And you also need to have an intermediate which in this case will be F: F + NO2 ---> NO2F (again all gases) This is the fast step. Your intermediate cancels out to give you your overall equation: 2NO2 + F2 ---> 2NO2F (all gases)</span>

natita [175]

Answer:

We will use an acid-base indicator to see changes in colour depending on the pH  

Explanation:

The pH changes during a titration, so you could use an acid-base indicator to follow the changes in pH.

A is wrong. An acid-base titration does not usually form a solid, and it would be impractical to isolate a solid with a funnel.

B is wrong. There are no changes in mass.

C is wrong. Any changes in temperature would be too small to measure precisely with an ordinary thermometer.
