Answer:
2,7,4,6
Explanation:
atoms at the left side should be equal to that of right for an equation to be balanced. so the answer is the final one
Answer:
B - The high temperature makes the gas molecules spread apart according to Charles's law because this law describes how a gas will behave at constant pressure.
Explanation:
Charle's Law describes the relationship between temperature and volume, where increased temperature leads to increased volume. When volume is increased, that means the gas molecules are more spread apart and have more random motion. Therefore, the answer is B.
<span>Option 4 is the correct answer. Rutherford concluded that the atom's volume was mostly empty space because the stream of alpha particles he directed at the gold foil arived at his detection aparatus mostly intact, indicating that relatively few of the alpha particles had been deflected. This follows because if the atom had not been empty space then the alpha particles would have encountered resistance and gone off course.</span>
Answer:
Atoms of different elements, having gained or lost electrons, form negative and positive ions that are bonded together by attractive forces between ions with opposite charges.
Explanation:
The atoms have different numbers of neutrons and the same number of protons. hope this helps you :)
Answer:
A. an acid
B. a base
C. conjugate base
D. conjugate acid
Explanation:
This question appears incomplete because it is starting with a "or".
However, the available question can still be answered.
An acid (according to "Bronsted-Lowry") is a chemical compound/specie that can donate hydrogen ion(s) in a reaction while a base is the compound/specie that can receive hydrogen ion(s). From this definition, <u>it can be deduced that</u> CH₃COOH <u>(ethanoic acid) is an acid (weak acid) because it can donate an hydrogen ion while</u> CH₃COO⁻ <u>is a base because it can receive a hydrogen ion</u>.
Also, a conjugate acid is the compound formed when an acid has donated a hydrogen ion to a base (i.e it is a base with hydrogen ion attached to it) while a conjugate base is the acid that has lost it's hydrogen ion. Thus, <u>the conjugate acid in the question is</u> CH₃OH <u>while the conjugate base in the question is</u> CH₃O⁻.
A. an acid
B. a base
C. conjugate base
D. conjugate acid
