Answer:
B) neuron or nerve cell work is to carry messages
Answer:
Each molecule contains one atom of A and one atom of B. The reaction does not use all of the atoms to form compounds.
A + B ⟶ Product
Particles: 6 8 6
If six A atoms form six product molecules, each molecule can contain only one A atom.
The formula of the product is ABₙ.
If n = 1, we need six atoms of B.
If n = 2, we need 12 atoms of B. However, we have only eight atoms of B, so the formula of the product must be AB.
Thus, 6A + 6B ⟶ 6AB, with two B atoms left over.

B. sounds like the most reasonable answer.
With an increase of people studying space exploration and sharing their discoveries, then it is likely for it to inspire other people in study science as well.
Answer:
The amount of molecules → 6.02×10²³
Explanation:
Avogadro Number (NA) is the amount of particles that are contained in 1 mol of anything.
It does not matter the mass of compounds, or molecules, 1 mol has 6.02×10²³ particles, the same number for every compound.
1 mol of H₂O that weighs 18 grams has 6.02×10²³ molecules
1 mol of sucrose, that weighs 342 g has 6.02×10²³ molecules
Generally, the NA is the number of atoms in 12 grams of the carbon-12 isotope.
Answer:
All of the above.
Explanation:
Hello there!
In this case, according to the definition of the Lewis structures, which are represented by the valence electrons, we first identify that the N atom has five valence electrons and each fluorine has seven valence electrons.
In such a way, we cans say that N is the central atom due to its lower electronegativity, the molecule has 7+7+7+5=26 valence electrons and the three F-N bonds are covalent, therefore the answer is all of the above.
Regards!
