Answer:
Explanation:
Molecular Formula is representation of the chemical compound in terms of the symbols of all the elements that are present in the compound followed by subscripts, which give the count of each element in that compound.
We need to write the molecular formula of Tricarbon nonachloride. Tri means three, so Tricarbon means there are 3 atoms of Carbon. Likewise, nona stands for 9, so nonachloride means there are 9 atoms of chlorine. Therefore, we can represent nonachloride as:
Carbon (3 atoms) Chlorine (9 atoms) =
Thus, molecular formula of Tricarbon nonachloride is

Explanation:
It would make sense for the United States to use SI units in everyday life because most calculations they do, in daily activities such as business and science, affect people in other parts of the world. For example, a United States writer who writes about weight in pounds(lb) and ounce(oz) might not be easily understood by a reader in many other countries of the world. This is because the reader might not be able to convert the measurement using the standards of the SI units where weight is measured in kilograms(kg).
The international system of units is the upgraded system of measurement from the metric system and it is used by almost all the countries of the world except three countries of which the United States is included.

The correct answer would be 0.1505 M/s. Given the rate of disapperance of HBr, we can easily calculate the rate of apearance of the products by looking at the coefficients of the substances in the reaction. In this case, for every two moles of HBr, 1 mole of Br2 is being produced so the reaction rate would be:
- 1/2 (r(HBr)) = rBr2
- 1/2 (-0.301) = rBr2
Rate of appearance of Br2 = 0.1505 M/s
