Answer:
2HNO3+ Ba(OH)2 = Ba(NO3)2 + 2H2O
H3PO4 + Ca(OH)2 = Ca3(PO4)2 + 6H2O
Explanation:
2HNO3+ Ba(OH)2 = Ba(NO3)2 + 2H2O

Answer: The pH of the solution is 5.65
Explanation:
The relationship between the pH and the pOH is that 
.
Given this, we can plug in the pOH and subtract that from 14.
I hope this helped! Pls give brainliest!! :)
Answer:
1' and 5' carbon.
Explanation:
DNA is the genetic material of almost all the living organisms but exceptions are involved in case of some viruses that contains RNA as their genetic material.
The DNA consists of the nitrogenous base, dexoyribose pentose sugar and the phosphate group. The base is attached with the sugar on the 1' position. The phosphate group is linked with the sugar at 5 position of the dexoyribose sugar.
Thus, the correct answer is 1' and 5' carbon.
Answer:
35 mL
Explanation:
Let the amount of 75% mixture needed be A.
The amount of each solution with their respective concentration to be added together can be expressed as:
0.75A + 0.3(280)...............eqn 1
The addition of the two solution must merge with the expected concentration and this can be expressed as:
0.35(A + 280).............eqn 2
Eqn 1 must be equal to eqn 2, hence:
0.75A + 0.3(280) = 0.35(A + 280)
Solve for A.
0.75A + 84 = 0.35A + 98
0.40A = 14
A = 35
Hence, 35 mL of the 75% mixture will be needed.
