To solve such this we must know the concept of chemical reaction. Therefore the correct option is option C that is the properties and identity of the reacting substances.

<h3>What is chemical reaction? </h3>

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

A change in the properties and identity of the reacting substances means that a chemical reaction has occurred.

Therefore the correct option is option C.

Which type of intermolecular or interatomic force does methylated spirits fall under?​
Triss [41]

Of all the substances used, water possesses the strongest intermolecular forces (hydrogen bonds). Although hydrogen bonds exist in glycerin and methylated spirits as well, they are a little weaker than in water.

Intermolecular forces in ch3oh include London dispersion forces, dipole dipole attraction, and hydrogen bonding. Methylated spirits, a common industrial solvent, are mostly made of ethyl alcohol. Because methanol denatures ethyl alcohol, commercial supply is exempt from the typical taxes and charges imposed on alcohol. A quantity of methyl alcohol or phenol is added to make it so that drinking it will make you go blind. Alcohols have the hydrogen bonding and van der Waals intermolecular forces of attraction.

A scooter maintains a pace of 1.45 minutes per mile, with fuel economy of 85 miles per gallon. How many seconds can it travel on
vlada-n [284]

Answer:

281s

Explanation:

Given parameters:

Speed of the scooter  = 1.45min per mile

Fuel economy of engine  = 85miles per gallon

Quantity of fuel  = 145mL

Unknown:

Time of travel with the volume of fuel given  = ?

Solution:

To solve this problem, we need to find the distance the fuel will last.

 Rate of fuel consumption by the engine  = 85miles per gallon

Convert 145mL to gallons;

                3785.41mL  = 1 gallon

               145mL will therefore give \frac{145}{3785.41}    = 0.038gallons

So;

   Distance covered  = 85miles per gallon  x 0.038gallons  = 3.23miles

From;

             Rate of travel  = \frac{time }{distance}  

       Time  = rate of travel x distance  = 1.45 minutes per mile x  3.23miles

     Time  = 4.7min

             1 min  = 60s

            4.7min  = 4.7 x 60 = 281s
