Answer:
Demonstrate familiarity with the pH scale ... body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). ... The pH of a solution is a measure of its acidity or alkalinity (base). ... Using a pH meter, you find the pH of an unknown solution to be 8.0.
Explanation:
Not sure what options I have but I have one term that identifies a form of energy which is “Energy is found in different forms, such as light, heat, sound and motion. There are many forms of energy, but they can all be put into two categories: kinetic and potential” Hope this helps.
As per the International System of Units is a form of metric system in which distance is expressed in meters.
The given distance is 45.2 cm
Convert centimeter (cm) to SI base unit (meter)
One hundred centimeters is equivalent to one meter
I.e. 100 cm = 1 m
Therefore, the given distance of 45.2 cm =
= 45.2 cm * 1 m/100 cm = 0.452 m
Thus, the correct SI base unit for 45.2 cm = 0.452 m
I think the correct answer would be negative change in enthalpy, low temperature and negative entropy. Freezing of water is an exothermic process which means heat is released to the surroundings so negative enthalpy. And this is seen in the change to a lower temperature. Entropy is negative which signifies that there is more order as water freezes.
