Hello!
The light from the sun hits one side of the moon and doesn’t hit from the other side. So that’s how we view it on earth
Hope this helps! Correct me if I’m wrong :)

Answer:(1)The urinary system's function is to filter blood and create urine as a waste by-product.
(2) two kidneys we have.
(3)The kidneys act as very efficient filters for ridding the body of waste and toxic substances, and returning vitamins, amino acids, glucose, hormones and other vital substances.
(4)Two ureters.
These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys.
(5)A hollow, muscular, balloon-shaped organ that expands as it fills with urine.
(6)The urethra is the vessel responsible for transporting urine from the bladder to an external opening in the perineum.
(7)Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.

Answer:
-2.07 × 10³ kJ
Explanation:
Let's consider the following balanced equation.
4 NH₃(g) + 5O₂(g) → 4 NO(g) + 6H₂O(g) ΔHrxn =−906 kJ
The enthalpy of reaction is -906 kJ, that is, 906 kJ are released upon the reaction of 4 moles of NH₃. Taking into account that the molar mass of NH₃ is 17.0 g/mol, the heat associated with the complete reaction of 155 g of NH₃ is:
Answer:
1200 mL
Explanation:
Given data
- Initial pressure (P₁): 600.0 mmHg
- Initial volume (V₁): 400.0 mL
- Final pressure (P₂): 200.0 mmHg
For a gaseous sample, there is an inverse relationship between the pressure and the volume. If we consider the gas as an ideal gas, we can find the final volume using Boyle's law.
The mass number of an atom is the sum of its protons and neutrons. the most common isotope of argon is ar-40 (40 ar), with a natural abundance of 99.6 %. the mass number for ar-40 is 40 . It is having 18 protons and 22 neutrons. So its mass number is 40 that is equal to sum of total number of protons and neutrons.
Mass number=total number of protons and neutrons
=18+22
=40
