Answer:
2:6 because 2:6 is equivalent to 1:3
Step-by-step explanation:
1x1=1 and 3x2=6
The buffer will probably be destroyed by the addition of HCN.
<h3>What is buffer solution?</h3>
A weak acid and the conjugate base of the weak acid, or a weak base and the conjugate acid of the weak base, are combined to form the buffer solution, a water-based solvent solution. They withstand being diluted or having modest amounts of acid or alkali added to them without changing their pH.
Given that a 1.0 l buffer solution is 0.15 m in HCN and 0.10 m in NaCN.
We need to find a action which one destroy the buffer solution.
A buffer is a substance made of salt and a weak acid that is beneficial. From the aforementioned chemicals, HCN is a potent acid and NaCN is a salt between HF and NaCN. Therefore, the buffer will probably be destroyed by the addition of HCN.

4a^2c^2(a^2-b^2+c^2)^2
First, solve the exponent around the quantity. Being that it's a power of a power, you would multiply all the exponents inside the parentheses by two. So, after that, it would be:
4a^2c^2(a^4-b^4+c^4)
Then, you would multiply what's outside the parentheses with every term within the parentheses:
(4a^6c^2)-(4a^2c^2b^4)+(4a^2c^6)
Now, you think you can take it from here, or do you need me to keep going?
Answer:
12 and 18
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 = 5
30 ÷ 5 = 6 ← value of 1 part of the ratio
2 parts = 2 × 6 = 12
3 parts = 3 × 6 = 18
The numbers are 12 and 18
