Answer:
slippery, high pH, and caustic (last option)
Explanation:
when we say base we should think soap. soap is slippery. Bases give OH- ion. when OH- is combined with H+ ion it will create water which raises the pH. Since base can dissolve fats, ex: using dish liquid to cut grease on pots and pans etc.. they are caustic. Biologically they can disrupt the cell memebrane making it caustic to cell tissue.
Ability to moderate temperatures is not a property of water
Answer:
a. 2
b. 10
c. 6
d. 14
Explanation:
The maximum number of the electrons which can be filled in the s orbital are:- 2
The maximum number of the electrons which can be filled in the p orbital are:- 6
The maximum number of the electrons which can be filled in the d orbital are:- 10
The maximum number of the electrons which can be filled in the f orbital are:- 14
Thus,
a. 3s can have maximum of 2 electrons.
b. 3d can have maximum of 10 electrons.
c. 4p can have maximum of 6 electrons.
d. 4f can have maximum of 14 electrons.
Answer:Reliability
Explanation:
Reliability of a test refers to how consistently a test measures a characteristic under the same conditions.
Reliability can be defined as the degree of consistency of which a chemical test gives a similar result. measure. A test is said to be highly reliable when it gives the same repeated result under the same conditions of measure.
But when a test gives different results under the same condition of measure it has a low reliability.
Hence, If a test yields consistent results every time it is used, it has a high degree of reliability.
