The specific gravity of water is 1.0 True
Redox reaction is the reduction and oxidation reaction. It is a chemical reaction that involves a transfer of electrons. It can mean loss of oxygen (oxidation) or gain of electrons (reduction). Oxydation is the process of where a sustance loses electrons, gains an oxygen atom/s, loses a hydrogen atom/s. reduction is the opposite.
In a redox reaction, one of the reactants must release electrons.
Answer:
Te is considered a Group A element.
Explanation:
Fe, Hg and Y belong to Group B.
U is a transition element.

I hope I've solved your doubt.
The titration reaction is written as follows:
Ba(OH)2 + 2HNO3 = Ba(NO3)2 + 2H2O
The calculations are as done as follows:
0.100 mol HNO3 / L (.03445 L solution ) = 0.003445 mol HNO3
0.003445 mol HNO3 ( 1 mol Ba(OH)2 / 2 mol HNO3 ) = 0.001723 mol Ba(OH)2
0.001723 mol / 0.025 L = 0.07 M Ba(OH)2
