when you hit a chemical with hammer and it was frozen only its physical properties will change and not he chemical properties,
when heated it may decompose to other chemical
when you hit with hamer it physical appearance will change but it remains chemically the same
when you put in salt solution , it wil interact with ions and its chemical properties changes
similarly when it was frozen, it retains its chemical properties.
The anwer roght here is the last one d. 0.0556 mol. The next procedure says why this is right:
<span>3.35 x 10^22 atoms x (1 mol / 6.02 x 10^23 atoms) = 0.0556 mol
</span>
I hope this can help you greatly
Answer:
You never listed the options

Hope this helps!
Answer:
Bleach, seawater, blood, water, coffee, orange, lemon
Explanation:
The pH is a measurement in chemistry defined as the -log [H⁺]. pH is used in quality control of materials. The pH is a scale from 1 (Acids) to 14 (Bases). The pH of 7 is for neutral solutions
Based on the information of the image, the most basic is bleach, then the seawater, the blood, water (Neutral), coffee, orange and, the most acidic is lemon.
The order is:
<h3>Bleach, seawater, blood, water, coffee, orange, lemon</h3>
