what is a non-polar molecule? Atoms are made of small particles. When atoms bond together to form molecules. They share or give electrons. If the electrons are shared equally by the atoms, then there is no resulting charge making the molecule nonpolar. Polar molecules are the complete opposite.
Answer:
The correct answer is True.
Explanation:
In the kidney, the handle of Henle is a fork-like tube located in the nephrons. It is the portion of the nephron that leads from the proximal contoured tubule to the distal contoured tubule. The primary filtrate from the glomerulus passes into the proximal contoured tubule, which connects to the descending branch of the loop of Henle, which has low permeability to ions and urea (solutes) but is very permeable to water.
Have a nice day!
If you mean hydrate as in <em>MgSO4 · 7H2O, </em>then simply find the molar mass of each element you see.
For the example above, that means you would add the molar mass (found on the periodic table) of Mg, then S, then 4(O), 14(H), and 7(O).
The results would be your molar mass for the hydrate.
I hope this is what you meant by your question!
Answer:
write down each element and what you need to know about it repeatedly, and it will burn into your brain

Answer:
If a neutral atom has 22 protons inside its nucleus, it will have 22 electrons orbiting the nucleus.
Explanation:
An atom is the smallest amount of matter that undergoes chemical changes and is made up mainly of subatomic particles: electrons, protons and neutrons. The atomic nucleus is made up of protons, with a positive electric charge, and neutrons, which have no charge, while electrons, with a negative electric charge, revolve around the nucleus.
A neutral atom is one that lacks an electrical charge due to a trade-off between the number of its protons and electrons. In other words, although it has an electric charge, it is balanced between protons, electrons and neutrons. So in a neutral atom, the number of electrons equals the number of protons because the negative charge of the electrons is offset by the positive charge of the protons.
