1identify the #
2place a decimal in a location which would make a #between 1and9
3 count the # of space values that the decimal moved
4 plug the numbers into this formula number from step 2×10 place value
example:
1) 330,000
2) 3.3 0000
3) count the places moved 5
4)plug the # in 3.30×10 to the 5th power.
Answer:
A
Explanation:
I looked up aromatic hydrocarbon and this one looks like a replica of benzene
Answer:

Explanation:
When carbon dioxide dissolves and reacts with water, the water and the gaseous
reacts to form a dilute mixture solution of
(carbonic acid ).
The reaction is 
This is a forward reaction. And the symbol
shows that the reaction can be reversible. It means that the reaction can be carried in forward direction as well as in the backward direction.
The reaction attains chemical equilibrium until the reactants and the products no longer changes with time.
The carbonic acid can also dissociates into carbon dioxide and water in the backward direction.

Answer: An arrow pointing to the left, and an arrow pointing up.
Sorry if im wrong and have a wonderful day!!!!!
Answer:
Synthesis
Explanation:
Reaction Given:
NH₃+ HCI ------> NH₄Cl
Type of reaction = ?
Solution:
Look at the reactants and products of the reaction to know the type of reaction
NH₃+ HCI ------> NH₄Cl
In this reaction two reactant combine and give 1 products.
Reactant of the reaction
NH₃ = Ammonia
HCl = Hydrochloric acid
Product of the reaction
NH₄Cl = Ammonium chloride
So,
That ammonia (NH₃) react with Hydrochloric acid (HCl) and produces salt.
in this reaction NH₃ is a week base and take a proton from HCl and form ammonium ion and Cl ion. these two ions in combine form gives a salt called ammonium chloride.
Type of Reaction:
This is type of synthesis reaction, in which NH₃ and HCl combine and form a new compound that is ammonium chloride salt (NH₄Cl). As the synthesis reaction is that reaction in which two are more compounds or molecules combine and form a new compound.
