Amarathon covers a distance of 26.2 miles. if 1 mile is equivalent to exactly 1760 yards, what is the distance of the race in yards? use dimensional analysis.

Both mile and yard are units of distance thus they are inter convertible.

Distance covered in a marathon is 26.2 miles.

Since, 1 mile=1760 yards

Thus, distance can be converted into yards using the following conversion factor:

Thus, distance covered in marathon in yard will be:

Therefore, distance of the race is 46112 yards.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
