Answer:
it's
C. with melting point 11° C and boiling point 181° C
Explanation:
i hope you got it
Answer:
Because only a few bacterias can "fix" the atmosphere nitrogen.
Explanation:
The nitrogen at the atmosphere is in the form of N₂ and represents 78% of the atmosphere composition. The element is part of the constitution of nucleic acids and proteins, so the living beings needed them.
However, the animals and the plants can't catch the N₂. Some bacterias that live in mutualism with plants have this ability, and they "fix" the atmosphere nitrogen, transforming the N₂ in the ions nitrite (NO₃⁻) or ammonia (NH₃), which can be caught by the plants.
Them, when the primary consumers eat the plants they catch the nitrogen, which will be passed through the food chain.
So, it's difficult to pull nitrogen from the atmosphere into the nitrogen cycle of the biosphere because only a few bacterias can do it.
Explanation:
Chemical reaction equation for the give decomposition of
is as follows:.

And, initially only
is present.
The given data is as follows.
= 2.3 atm at equilibrium
= 0.69 atm
Therefore,

= 0.23 aatm
So,
= 2.3 - 2(0.23)
= 1.84 atm
Now, expression for
will be as follows.


= 
= 0.0224
or, 
Thus, we can conclude that the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture is
.
Answer:
Speed and acceleration
Explanation:
i would say this bc the formula is related to acceleration if you looking at all the possible exceptions im not a expert in this range but im just giving you what i would pick so if you get it wrong im sorry lol.
<span> When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable</span>
