Answer:
The exposure time that equals 750 is 3.4 hr
Explanation:
The given formula is:
![[tex]T=.0002*x^{2} -.316*x+127.9](https://tex.z-dn.net/?f=%5Btex%5DT%3D.0002%2Ax%5E%7B2%7D%20-.316%2Ax%2B127.9)
[/tex]
In the formula:
T= exposure time
x= carbon monoxide present in ppm
So, to calculate the exposure time when carbon monoxide is 750ppm, you should replace the "x" by 750.
![[tex]T=.0002*750^{2} -.316*750+127.9](https://tex.z-dn.net/?f=%5Btex%5DT%3D.0002%2A750%5E%7B2%7D%20-.316%2A750%2B127.9)
[/tex]
T=3.4hr
Table salt is sodium chloride mixed with small<span> amount of </span>potassium iodide (KI)<span>, </span>sodium iodide (NaI)<span> or </span>sodium iodate (NaIO₃)<span>.
Atomic level - sodium chloride (NaCl) has crystal cubic structure (</span>lattice-type arrangement)<span> with ionic bonds. Sodium is cation with charge 1+ and chlorine is an anion with charge 1-.
Macroscopic level - table salt is c</span>olorless crystal, soluble in water with high melting and boiling temperature..

Explanation:
The reaction between formic acid and potassium hydroxide is an acid base reaction.
Remember that an acid base reaction yields salt and water only.
If you look at the curved arrow mechanism shown, you will discover that the hydroxide ion from KOH abstracts a proton from the acid to yield potassium formate and water
Answer:
MgS is the formula and Magnesium sulfide is compound name
Explanation:
Answer:Use an excess of ethane
Explanation:
The halogenation of alkanes is a substitution reaction. All the hydrogen atoms in the alkanes could be potentially substituted. How ever the reaction can be controlled by using an excess of either the alkane or the halogen. If the aim (as it is in this question) is to minimize the yield of halogenated alkanes, an excess of the alkane (in this case, ethane) is used.
