The _____________ is measuring a volume of water in _________________.
ASHA 777 [7]

Answer:

The "graduated cylinder" is measuring a "volume of water" in "milliliters".

Option: D

Explanation:

Measuring of "liquid" in "milliliters" we use "graduated cylinder". This represents the "volume of the water" or the "liquid". The "graduated cylinder" is labelled with the dimensions in the "milliliters". Measuring with "graduated cylinder" is some what difficult because of the "meniscus", this "meniscus" is the "curvature" of the surface of the water in the "graduated cylinder". The only problem is "meniscus" is attached to the edges of the cylinder but not in the middle of the cylinder. While looking at the cylinder the "meniscus" is not straight, hence the person should keep the "graduated cylinder" at his eye level.

A Group 2 metal with an electron configuration of [Ne]3s2 combines with fluorine (F2) to
lidiya [134]

The molar mass of the product is equal to 62g/mol.

<h3>Mole calculation</h3>

To calculate the molar mass of a compound it is necessary to have knowledge of the atomic mass of all the elements involved.

In the case of the question, we have the reaction between flourine and magnesium, which represents the element of group 2 with the presented electronic configuration.

Thus, we have the following reaction:

                                   Mg^{+2} + 2F^{-1} = MgF_2

So, just add the molar masses, having:

MM_Mg = 24.3g/mol\\MM_F = 19g/mol

                                               24.3 + 19 + 19 = 62.3g

So, the molar mass of the product, round to the nearest tenth, is equal to 62g/mol.
