My answer -
The scientist that performed the cathode ray experiment leading to the discovery of electrons is<span> the
scientist Sir Joseph John Thompson or J.J. Thompson. It was theorized
after the discovery that electrons are present in the atom. In this
model, the atom is composed mainly of electrons. It was describe as plum
pudding because the electrons are dispersed within the atom.
P.S
Happy to help you have an AWESOME!!! day ^-^

Answer:
How many hydrogen MOLECULES are needed to produce 2 molecules of water (H2O)?
Explanation:
The strength of an acid increases if the stability of conjugate base increases
The stability of a conjugate base increases with the presence of electron with drawing group (electronegative group)
Thus more the electronegativity of an atom attached to a carboxylic acid higher the strength of acid
In these examples CH3CH2CH2CF2CH2COOH contains to electronegative flourine atoms which stabilizes the conjugate base hence this will be the strongest acid among the given acids
Answer:
25 grams
Explanation:
You strat off with 400 grams of your substance. By day 14, half has dcayed and you only have 200 grams left. By day 28, there are 100 grams of the substance. On day 42, there are 50 grams left. Finally, on day 56, the substance has been through four half-lives and 25 grams remain.
