An empirical formula is the "reduced" version of a molecular formula. For example, CH3 is the empirical formula for C2H6, C3H9, C4H12, and so forth. The difference in subscripts between an empirical formula and molecular formula is given by the constant n. If n is a whole number, this means the numerator is the molecular formula. So the answer is D. <span>subscript of C in molecular formula = n  subscript of C in empirical formula. This can be rewritten as:
n = subscript of C in molecular formula/subscript of C in empirical formula</span>
Answer: -
60 mL of potassium chloride 20% should be diluted to prepare 480 ml of potassium chloride 2.5%
Explanation: -
Volume of potassium chloride solution = 480 mL
Percentage of potassium chloride = 2.5%
Amount of Potassium chloride = 
x 480 mL
= 12 mL
Let the required amount be R.
20 % of R = 12 mL.
x R = 12mL
R = 60 mL.
Thus, 60 mL of potassium chloride 20% should be diluted to prepare 480 ml of potassium chloride 2.5%
Answer:
comes from a translation of the German word Edelgas, which means noble gas.
<em>Why Are Noble Gases Called Noble? The term “noble gas” comes from a translation of the German word Edelgas, which means noble gas. German chemist Hugo Erdmann coined the phrase in 1898. Like a nobleman might consider it undignified to associate with commoners, noble gases tend not to react with other elements.</em>

Answer:
undergo death as result of the water loss from cell
Explanation:
The ingredients such as honey, jellies, Jams, preserves and other food which have high sugar content are contaminated hardly by the bacteria because due to the presence of high amount of the sugar and carbohydrates, the solution of the them becomes hypertonic in nature and if a bacteria acts on such solution, the result is the loss of the water from their cell and ultimately the bacteria dies. So, they remain fresh even if their containers are left open at the room temperature.
Answer:
Platinum is a greyish-white metal of high lustre, and is very malleable and ductile. It melts in the oxy-hydrogen blowpipe and in the electric furnace; it is harder than gold and is a good conductor of electricity. In finely divided form it has the ability to absorb or occlude gases
