1.Some earthquakes are associated with volcanoes. A lot of earthquakes are alongside the rims of tectonic plates. This is in which some volcanoes are too.
2. Earth changes in its personal ways. Some changes are because of gradual processes, consisting of erosion and weathering, and a few changes are because of fast processes, consisting of landslides, volcanic eruptions, Tsunamis and earthquakes. Waves, wind, water, and ice form and reshape the Earth's land surface through eroding rock in a few regions and depositing them in different regions, now and again in seasonal layers. Tectonic plates drift, the crust quakes, and volcanoes erupt. All of these effective forces form our air, land, water, and climate and are constantly reworking our planet.

A compound with the empirical formula C2HF4 was found to have a molar mass of about 200g/mole. What is the molecular formula of
alukav5142 [94]

Answer:

C_4H_2F_8 is the molecular formula of the compound.

Explanation:

For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.

The equation used to calculate the valency is :

n=\frac{\text{molecular mass}}{\text{empirical mass}}

We are given:

Mass of molecular formula = 200 g/mol

Mass of empirical formula of C_2HF_4 :

2 × 12 g/mol + 1 × 1 g/mol + 4 × 19 g/mol = 101 g/mol

Putting values in above equation, we get:

n=\frac{200 g/mol}{101 g/mol} =1.9 \approx 2

Multiplying this valency by the subscript of every element of empirical formula, we get:

C_{(2\times 2)}H_{(1\times 2)}F_{(4\times 2)}=C_4H_2F_8

C_4H_2F_8 is the molecular formula of the compound.
