Explain the difference between the reacts and products of a chemical reaction

Chemistry
1 answer:
Alika [10]3 years ago
5 0
Reactants are what is changed in the chemical reaction. They go before the arrow when you wrote the equation. Products are what is formed when the chemical reaction occurs. Products always contain the same elements as the reactants, but they might be rearranged because of the reaction. In this picture, you can see that the reactants go before the arrow, and the products go after.

How many seconds does it take a race horse to run six furlongs at 40.7 miles per hour if: I furlong = 40 rods; 5.5 yards = 1 rod
lana [24]

Distance traveled by the race horse=6 furlongs

Converting the distance from furlongs to rods: 40 rods =1 furlong

6 furlongs*\frac{40rods}{1furlong} =240rods

Converting the distance from rods to yards, feet and miles: 5.5 yards = 1 rod, 3foot =1 yard, 1 mile = 5280 feet.

240rods*\frac{5.5yards}{1rod}*\frac{3foot}{1yard}*\frac{1mi}{5280feet}=0.75mi

The given speed of race horse = 40.7mi/hr

Calculating the time required:

0.75mi*\frac{1hr}{40.7mi}*\frac{60min}{1hr}*\frac{60s}{1min}= 66.34s

Therefore, 66.34 s is required for a race horse to run six furlongs at 40.7 miles per hour.

Explain what makes one mineral so precious or costly compared to another.
ValentinkaMS [17]
There are multiple factors that contribute to the cost of a mineral. First of all is the demand or application, which will be related to its physical properties. For example, nontarnishing metals like gold are held in high value for their appearance. Second is the supply of the mineral, those that only have a small quantity in the earth's crust are likely to be more expensive. Third is the cost of extraction and manufacturing. Some minerals may be abundantly found, but may be distributed over a wide area, meaning that it is still expensive to mine and transport.
