1. It's not gonna be A, B, or C because redox means when the electrons transfer both ways and a b and c dont show that. Bw d and E i'd go for D.
for 2.
I'd say B because both reactants are acqueous while 1 product is solid so it would probably precipitate.
good luck dadddddd
I believe u mean what is the difference between the two but nonpolar molecules have equaly sharing valence electrons and polar molecules have unequaly shared valence electrons.
The answer is (a) 30g. Zinc = 30. 1 mole = 30 x 1 = 30g
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.
