The Coefficients would be:
Hg(CO3)2: 1
AgCl: 4
HgCl4: 1
Ag2CO3: 2
How do we know this?
Because if we look at the coefficent for the first compound, Hg(CO3)2, That means in total we have one Hg and 2 CO3's.
IF the coefficient is 4 for the next compound, AgCl, there are 4 Ag's and 4 Cl's.
Those were the REACTANTS to our equation. Now looking at the arrow, HgCl4 and Ag2CO3 are our PRODUCTS, or, what is FORMED from Hg(CO3)2 and AgCl. So, we need to make sure that they are equal, to obey the law of conservation of mass. So in simpler terms, if we have 4 Cl's on the reactant side, we need 4 on the products side.
So, if we had the coefficient of 1 for HgCl4, this makes sense, because on the products side we had 1 Hg, and 4 Cl's. With the coefficient of 1, we have 1 Hg and 4 Cl's on the products side, as well!
And if we had the coefficient of 2 for Ag2CO3, we would have 4 Ag's total and 2 CO3s, which matches on the reactants side, for we have two CO3's and 4 Ag's.
I hope I could help!
Answer:
D. Sulfonation
Explanation:
Electrophilic aromatic substitution -
The subsitution reaction , where the hydrogen atom of an aromatic ring is replaced by an external electrophile .
Sulfonation reaction -
The subsitution reaction , where the hydrogen atom of an aromatic ring ( benzene) is replaced by an sulfonyl group , is called an Sulfonation reaction .
The Sulfonation reaction is reversible in nature , because , heating of aqueous sulfuric acid with sulfonic acid , can lead to a reverse reaction , i.e. , desulfonation .
A because KCL 2 and K + CL cancel out and Both of the Ca cancel each other out
Answer:
the Milky Way galaxy
Explanation:
It's between the Sagittarius and Perseus Arms of the Milky Way.
Answer:
I think in the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: <u>ATP</u> and <u>NADPH</u>. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.
Hope this help you!:)
