Answer:
6
Explanation:
You have the unbalanced chemical reaction:
BF3 + Li2SO3 ⇒ B2(SO3)3 + LiF
Knowing that there are 2 atoms of boron in the products, we need to adjust that element putting 2 as coefficient of BF3.
2BF3 + Li2SO3 ⇒ B2(SO3)3 + LiF
Then, we need to balance fluor. There are 6 atoms of F in the reactants, for that reason, we write 6 in the lithium fluoride.
2BF3 + Li2SO3 ⇒ B2(SO3)3 + 6LiF
Finally, sulfur and oxygen have to be adjusted. 3 before lithium sulfite is enough to balance the chemical reaction.
2BF3 + 3Li2SO3 ⇒ B2(SO3)3 + 6LiF
Answer: hopefully this is right UwU
Explanation: The infrared spectrum of a sample is recorded by passing a beam of infrared light through the sample. When the frequency of the IR is the same as the vibrational frequency of a bond or collection of bonds, absorption occurs. Examination of the transmitted light reveals how much energy was absorbed at each frequency (or wavelength).
Asphalt is a biproduct of making gasoline, diesel, kerosene, jet fuel, all from crude oil pumped from the ground. Asphalt is the garbage or waste that comes out the bottom of the process of distilling those products. They heat the thick oily-sooty gunky asphalt and mix it with rock or sand and make roads out of it. So the compound would be the long hydrocarbon chains.

Answer:
The balanced reaction is given by,
⇒ 
Explanation:
The reaction is as given.
Lets count the number of each elements in the reaction.
<em>In reactant side, number of sodium atoms are 1 , lead are 1, nitrogen are 1 and oxygen are 4.</em>
<em>in product side, number of sodium atoms are 2 , lead are 1 , nitrogen are 2 and oxygen are 7.</em>
<em>So we need to balance sodium and oxygen atoms in the reaction.</em>
<em>There is deficient of sodium and oxygen atoms on reactant side</em>.
Thus, multiply (NaNO3) by 2.
<em>Thus, sodium atoms become 2 , nitrogen 2 and oxygen 6. Total 7 oxygen atoms.</em>
Thus, the balanced reaction is,
⇒
