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.

Answer:
D. 76%
Explanation:
Percent yield=actual/theoretical * 100
38/50 * 100 = 76%
The number of moles of each atom present in 5 moles of Cu₃(PO₄)₂ are:
- 15 moles of Cu
- 10 moles of P
- 40 moles of O
<h3>Description of Cu₃(PO₄)₂</h3>
- 1 mole of Cu₃(PO₄)₂ contains
- 3 moles of Cu
- 2 moles of P
- (2×4) = 8 moles of O
<h3>How to determine the mole of each atom </h3>
The moles of atom present in 5 moles of Cu₃(PO₄)₂ can be obtained as follow
<h3>For Cu</h3>
1 mole of Cu₃(PO₄)₂ contains 3 moles of Cu.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 3 = 15 moles of Cu
<h3>For P</h3>
1 mole of Cu₃(PO₄)₂ contains 2 moles of P.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 2 = 10 moles of P
<h3>For O</h3>
1 mole of Cu₃(PO₄)₂ contains 8 moles of O.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 8 = 40 moles of O

<u>Answer:</u> The correct answer is Option 1.
<u>Explanation:</u>
There are three subatomic particles in an atom. They are: electrons, protons and neutrons.
- <u>Protons:</u> They carry positive charge and are found in nucleus.
- <u>Electrons:</u> They carry negative charge and are found around the nucleus.
- <u>Neutrons:</u> They dos not carry any charge and are found in nucleus.
Mass of protons and neutrons are almost same and they both contribute to the mass of an atom.
Mass of electrons is very negligible as compared to protons and neutrons.
Masses of the subatomic particles:
Mass of protons = 1.007276 u
Mass of neutrons = 1.008664 u
Mass of electrons = 0.00054858 u
Hence, the correct answer is Option 1.
