Answer:
NBr₃ is the excess reactant.
Explanation:
- 2NBr₃ + 3NaOH → N₂ + 3NaBr + 3HOBr
We can solve this problem by <u>calculating how many moles of NaOH would react completely with 40 moles of NBr₃</u>, using the <em>stoichiometric coefficients </em>of the reaction:
- 40 mol NBr₃ *
=60 moles NaOH
As the required number of NaOH moles is higher than the available number (60 required vs 48 available), NaOH is the limiting reactant.
As such, the excess reactant is NBr₃.

Explanation:
The dissolution of salt in water is basically a physical process and the law of conservation of mass which states that mass can neither be created nor destroyed applies. The mass of each component before dissolution will be same after dissolution.
When one pound of salt is dissolved in 20 pounds of water, the resulting solution will weigh 1+20 pounds.
mass of solution = mass of salt + mass of water
= 1+20
mass of solution = 21 pounds

Answer:
polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited (usually a planet such as the Earth, but possibly another body such as the Moon or Sun) on each revolution. It has an inclination of about 60 - 90 degrees to the body's equator.[1] A satellite in a polar orbit will pass over the equator at a different longitude on each of its orbits.
Launching satellites into polar orbit requires a larger launch vehicle to launch a given payload to a given altitude than for a near-equatorial orbit at the same altitude, due to the fact that much less of the Earth's rotational velocity can be taken advantage of to achieve orbit. Depending on the location of the launch site and the inclination of the polar orbit, the launch vehicle may lose up to 460 m/s of Delta-v, approximately 5% of the Delta-v required to attain Low Earth orbit. Polar orbits are a subtype of Low Earth orbits with altitudes between 200 and 1,000 kilometers.[1]

Answer:
Cells make up the smallest level of a living organism such as yourself and other living things. The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the cell is called the fundamental unit of life.
