<h3><u>Given </u><u>:</u><u>-</u></h3>
- <u>We </u><u>have </u><u>given </u><u>equation </u><u>Cacl2</u><u> </u><u>+</u><u> </u><u>K2CO3</u>
<h3><u>Let's </u><u>Begin </u></h3>
<u>We </u><u>have </u><u>,</u><u> </u>

<u>Let's </u><u>balance </u><u>it </u>
<u>On </u><u>reactant </u><u>side</u><u>, </u>
<u>On </u><u>product </u><u>side</u><u>, </u>
<h3><u>Therefore</u><u>, </u><u>Balanced </u><u>equation </u><u>will </u><u>be </u><u>:</u><u>-</u></h3>

- <u>The </u><u>above </u><u>reaction </u><u>is </u><u>Double </u><u>displacement </u><u>reaction</u><u>. </u>
<u>Double </u><u>Displacement </u><u>reaction </u><u>:</u><u>-</u>
- Double displacement reaction is a reaction in which the ions of compound on a reactant side exchanges due to the varying reactivity of elements so that they can form new products.
Answer: bacteria, archaea, plants, protists, animals, and fungi
Explanation: Throughout the history of evolution, cellular respiration has been a central element of many organisms' functioning. Even as species have developed and changed through the process of natural selection, all of the successful, surviving individuals have kept the genes that allow them to produce the enzymes needed for cellular respiration.
D
A describes liquid, b describes solid, and c describes solid as well. therefore d is the only good answer
Answer:
The answer is in the explanation.
Explanation:
A buffer is defined as the aqueous mixture of a weak acid and its conjugate base or vice versa. Buffers are able to avoid the pH change of a solution when strong acid or bases are added (As NaOH).
Based on the experiment, it is possible that the solution Z was a buffer and Y another kind of solution. For this reson, pH of the solution Y changes much more than the pH of solution Z changes despite the amount of NaOH added is the same in both solutions.
