Answer:
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

Answer:
Explanation:
Considering:
Given :
For NaOH :
Molarity = 0.0500 M
Volume = 45.88 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 45.88×10⁻³ L
Moles of NaOH = Moles of monoprotic acid
So, moles of monoprotic acid = 0.002294 moles
Given that:- mass = 0.456 g
The formula for the calculation of moles is shown below:
Thus,
Answer:
3.
Explanation:
Hello,
In this case, it is convenient to write the chemical reaction as:
Which balanced turns out:
Thus the number that should be in front of the calcium sulfate is 3 in order to balance the reaction.
Best regards.
Nitrogen is a diatomic molecule in the VA family on the periodic table. Nitrogen has five valence electrons, so it needs three more valence electrons to complete its octet. A nitrogen atom can fill its octet by sharing three electrons with another nitrogen atom, forming three covalent bonds, a so-called triple bond.
