Question part in the given data is missing, however the missing part is as follows:
What safety rules were violated?
Answer:
The correct answer would be:
-Never work in the lab without teacher or adult present
-Keep chemicals away from hands and face.
-Do not touch lab supplies without permission
Explanation:
According to the lab safety and precaution rules one should follow the lab rules strictly to avoid any risk and mishap. These rules include, the chemical management, lab safety equipment, and many other rules including don not work in absence of teacher or the adult.
One should avoid touching chemical and equipment without permission of teacher and never touch chemicals with bare hand and not to touch chemical and keeps it from face.
Some atoms become unstable because NEUTRONS AND PROTONS ARE OFF BALANCE.
Neutrons and protons are the subatomic particles, which are found inside the nucleus. A nucleus is described as stable when its binding energy is enough to hold the nucleus together. When the binding energy is not enough to hold the nucleus together, the nucleus is described as unstable. In order to become stable the nucleus will lose protons and neutrons. <span />
It might be more suitable because some data cannot use a graph to show data because there is too much data.
<h3>Answer:</h3>
[OH⁻] = 1.0 × 10⁻¹⁰ M
<h3>Solution:</h3>
In order to calculate concentration of hydroxide ion i.e. [OH⁻] first we will find the pOH by using following relation,
pH + pOH = 14
Putting value of pH given and solving for pOH,
4.0 + pOH = 14
pOH = 14 - 4.0
pOH = 10.0
As ,
pOH = -log [OH⁻]
So,
[OH⁻] = 10^-pOH
Putting value of pOH,
[OH⁻] = 10⁻¹⁰
[OH⁻] = 1.0 × 10⁻¹⁰ M
Answer:
A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, and barnacles.
