Julia notices that the ""check engine"" light comes on while driving her car on days with temperatures of over 100 degrees. what
aev [14]

Option b), Julia's car engine overheats when the outside temperature exceeds 100 degrees is the best plausible explanation for her “check engine” light coming on while driving her car on days with temperatures over 100 degrees.

<h3>Reasoning</h3>

The other options that the engine needs to be replaced, that it cannot withstand high temperatures, or that Julia cannot drive her car on days when it is over 100 degrees outside are not plausible explanations for the situation because that is not what it indicates. the expression “check engine”

On the other hand, option b) is a plausible explanation because the light that comes on with the "Check engine" indicator is due to a temperature sensor that the engine has and that is activated once a certain temperature is exceeded.

In this case, the sensor is sensitive to a temperature differential, since it is activated when the motor compares the degrees of internal temperature with the external one.

If 30mL of 0.5M KOH is needed to neutralize 2M HCl, what was the volume of the acid?
defon
The equation for the reaction between KOH and HCl is as follows
KOH + HCl ---> KCl + H2O
the stoichiometry of KOH to HCl = 1:1
the number of KOH moles reacted = 0.5 mol /1000 cm³ * 30 cm³ 
                                                       = 0.015 mol
the number of HCl moles reacted = number of KOH moles reacted 
therefore HCl moles reacted =  0.015 mol
the molarity of HCl is 0.2 mol/dm³
0.2 mol of HCl in - 1000 cm³
Therefore volume required for 0.015 mol = 1000 cm³ / 0.2 mol * 0.015 mol 
                                                                 = 75 cm³
Therefore 75 cm³ of HCl is required

The properties of an unknown substance can be compared to the properties of a known substance to identify the unknown substance.
Nitella [24]

Answer:  Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.

Explaination:

By using Physical properties unknown substance can be identified as it involves determination of a substance with out changing their composition or property include color, odor, taste, density, melting point etc.

What are the difference between physical and chemical property ?

Chemical properties can be observed or measured when a substance undergoes any type of changes chemically while Physical properties can be observed without changing anything.

In chemical property, chemical reaction is conducted to show the property of the substance while in physical property No chemical reaction occur.

Chemical properties related to chemical bonds while Physical properties do not have such a relationship.

Chemical properties include radioactivity, toxicity, flammability, heat of combustion,  etc. while physical properties include Molecular weight, boiling point, melting point, freezing point, volume, mass, length, density shape, solubility, etc.
