Answer:
Calculate the pH of 0.010 M HNO2 solution. The K, for HNO2 is 4.6 x 104
Answer: pH = 2.72
Answer:
E) rate of appearance of C = 0.45 M/s
rate of the reaction = 0.15 M/s
Explanation:
2A + B → 3C
Writing rate law for the reaction:
<u>Rate of reaction</u> = - = - = → equation 1
Given that the rate of disappearance of A is 0.3 M/s
⇒ - = 0.3 M/s
⇒Rate of reaction = - = ×0.3 M/s
⇒<u>Rate of reaction = 0.15 M/s</u>
From equation 1, = - = ×0.3 M/s
⇒ = 0.45 M/s
or <u>the rate of appearance of C = 0.45 M/s</u>
<span>Among the benefits; enlarging so that you can see it visually, making something complex and hard to understand to simplify it. One draw back is that not entirely accurate because it is basic. Additionally; models help us to visualize smaller structures that are too small to see properly. However; they do not take all variables into account and thus they may be inaccurate. </span>
Explanation:
An atom consists of two regions. The first is the tiny atomic nucleus, which is in the center of the atom and contains positively charged particles called protons and neutral, uncharged, particles called neutrons. ... Most atoms contain all three of these types of subatomic particles—protons, electrons, and neutrons.
