Answer:
The answer to your question is b. CaCrO₄
Explanation:
Data
H₂CrO₄ reacts with Ca(OH)₂
Process
H₂CrO₄ is an acid and Ca(OH)₂ is a base then this is a neutralization reaction.
H₂CrO₄ is an acid and Ca(OH)₂ is a base.
In a neutralization reaction, the products will always be water and a binary or ternary salt.
In the reaction, the salt will be Calcium chromate
Balanced chemical reaction
H₂CrO₄ + Ca(OH)₂ ⇒ CaCrO₄ + 2H₂O
Answer:
D. The rock cycle is a series of processes in which one kind of rock is transformed into other kinds.
Explanation:
Answer:
607 ppm
Explanation:
In this case we can start with the <u>ppm formula</u>:
If we have a solution of <u>0.0320 M</u>, we can say that in 1 L we have 0.032 mol of , because the molarity formula is:
In other words:
If we use the <u>atomic mass</u> of (19 g/mol) we can convert from mol to g:
Now we can <u>convert from g to mg</u> (1 g= 1000 mg), so:
Finally we can <u>divide by 1 L</u> to find the ppm:
<u>We will have a concentration of 607 ppm.</u>
I hope it helps!
Answer:
After the ejection of an alpha particle, the remaining nucleus has a mass number that is four less and an atomic number that is two less, so alpha decay is a type of nuclear fission.
Answer:
Option (2) At equilibrium, there is a much higher concentration of products than reactants.
Explanation:
The equilibrium constant for a reaction is simply the ratio of the concentration products raised to their mole ratio divided by the concentration of the reactants raised to their mole ratio.
If the equilibrium constant is close to 1 or 1, it means the concentration of the reactants and products are almost the same. But if the equilibrium constant is large as in the case of the question given above, it means that at equilibrium, the concentration of the products are higher than that of the reactants.
