This is the chemical formula for nickel tetracarbonyl (a powerfully poisonous liquid used in nickel refining): Ni(CO)_4 A Chemical engineer has determined by measurements that there are 3.134 moles of nickel in a sample of nickel tetracarbonyl. How many moles of carbon are in the sample? Be sure your answer has the correct number of significant digits.

We have 12.54 moles of carbon are in the sample.

Explanation:

Step 1: Data given

Nickel tetracarbonyl = Ni(CO)4

Number of moles nickel = 3.134 moles

Step 2: Calculate moles carbon

For 1 mol Ni(CO)4 we have 1 mol Nickel, 4 moles carbon and 4 moles oxygen

If we have 3.134 moles nickel, this means we have 3.134 moles of Ni(CO)4

For 3.134 moles Ni(CO)4 we have 4*3.134 = 12.54 moles of Carbon

We have 12.54 moles of carbon are in the sample.

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
