Answer:No rhinos are not a producer. Rhinos are a primary consumer. A producer for example would be a plant such as grass.
Answer:
If liquid bromine is cooled to form a solid, which type of solid does it form? Brass is made by melting copper and zinc and physically mixing them. As this alloy is cooled, it forms a solid where the copper and zinc are not chemically bonded together.
Explanation:
Answer:
pure water, pH = 7.0 (Neutral)
lake water, pH = 6.5 (Acidic)
baking soda solution, pH = 9 (Alkaline)
soapy water, pH = 12 (Alkaline)
Explanation:
The degree of acidicity or alkalinity of a solution can be determined on a pH meter. A pH below 7 is acidic; a pH of 7 is neutral; a pH value of above 7 is alkaline.
Answer: Thus the pressure of the air in a car tire in psi is 25.4
Explanation:
Pressure is defined as the force exerted per unit area.
Thus units of pressure can be atm or psi or Pa.
Given :
Convert 1.73 atm to psi units
1 atm = 14.7 psi
Thus 1.73 atm = ![\frac{14.7}{1}\times 1.73=25.4psi](https://tex.z-dn.net/?f=%5Cfrac%7B14.7%7D%7B1%7D%5Ctimes%201.73%3D25.4psi)
Thus the pressure of the air in a car tire in psi is 25.4
