Answer:
The coefficients are 6, 1, 3
Explanation:
HNCO →C3N3(NH2)3 + CO2
From the above equation, there are a total of 6 atoms of nitrogen on the right side and 1atom on the left. It can be balance by putting 6 in front of HNCO as shown below:
6HNCO → C3N3(NH2)3 + CO2
Now there are 6 atoms of carbon on the left side and 4 atoms on the right side. It can be balance by putting 3 in front of CO2 as shown below:
6HNCO → C3N3(NH2)3 + 3CO2
Now the equation is balanced as the numbers of atoms of the different elements on both sides of the equation are the same.
The coefficients are 6, 1, 3
A. 1
B. 4
C. 5
D. 3
E. 2
The correct answer is E. 2
The radiation emitted is a beta particle with a -1 charge. <span>Beta particles have a </span><span>medium penetrating power. An emission of beta particles requires shielding because of the hazards it pose to humans. Thus, one characteristic of this radiation is that some shielding is required.</span>
If an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴, then the true statement about the salt produced is that the salt would decrease the pH of the solution.
<h3>What is acid and base constant?</h3>
An acid dissociation constant, Kₐ, is a quantitative measure of the strength of an acid in solution while Kb indicates the high level of dissociation of a strong base.
According to this question, an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴. This shows that the strength of the base is higher than that of the acid.
Therefore, if an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴, then the true statement about the salt produced is that the salt would decrease the pH of the solution.
