Answer:
Removing chemicals from pesticides that could be harmful to the environment
Explanation:
This is a main food issue that is not only state-wide but global
1st option doesn't say anything about food issues which makes it unnecessary to address
2nd option is a suggestion and not necessary
4th option is again not exactly towards food issues so no need to address for this question
5th option isn't a issue as much as just something we could do for convenience and stability
6th option should already be in act and is unlawful to do which leads me to the correct option
3rd option is correct because it is still okay globally to put chemicals into our food to keep it looking better for longer amounts of time. Yet it is dangerous to us living beings and the environment.
So therefore 3rd option is correct
(have a great day!)
Spinal Cord!!! I did this earlier :D It is spinal cord because you know that if you break your spinal cord you can't move. :P Brainiliest would be awesome thanks :D
Answer:
a. BH₃
Explanation:
According to the octet rules, atoms reach stability when are surrounded by eight electrons in their valence shell when they combine to form a chemical compound.
From the options, the only compound in which the central atom does not meet the octet rules is BH₃. The central atom is boron (B), which has 3 electrons in its valence shell. When B is combined with hydrogen (H), 3 electrons from the 3 atoms of H are added. The total amount of electrons is 6, fewer than 8 electrons needed to meet the rule.
hope this helps
If the number of atoms stays the same no matter how they are rearranged, then their total weight stays the same. In all physical and chemical changes, the total number of atoms remains the same, hence when substances interact with one another, combine or break apart, the total weight of the system remains the same.
Answer:
The answer to your question is the second option: 2M NaOH solution
Explanation:
Data
Volume 1 = 0.5 l
Concentration 1 = 12 M NaOH
Volume 2 = 3 l
Concentration 2 = ?
Formula
V₁C₁ = V₂C₂
Solve for C₂
C₂ = V₁C₁ / V₂
Substitution
C₂ = (0.5)(12) / 3
Simplification and result
C₂ = 6 / 3
C₂ = 2 M
