+1
Explanation:
To solve this problem, we need to set up an algebraic equation. Let us first understand the meaning of oxidation number.
The oxidation number is the formal charge assigned to an atom present in a molecule or formula unit
The algebraic sum of all oxidation numbers of atoms in an ion containing more than one kind of atom is the charge on the ion.
The algebraic sum of all oxidation number of atoms in a neutral compound is zero;
The radical NO₃ has a formal charge of -1;
let the oxidation number of Li = x
x + (-1) = 0
x = + 1

Answer:
Change in internal energy (ΔU) = -9 KJ
Explanation:
Given:
q = –8 kJ [Heat removed]
w = –1 kJ [Work done]
Find:
Change in internal energy (ΔU)
Computation:
Change in internal energy (ΔU) = q + w
Change in internal energy (ΔU) = -8 KJ + (-1 KJ)
Change in internal energy (ΔU) = -8 KJ - 1 KJ
Change in internal energy (ΔU) = -9 KJ

Answer:
The answer is True
Explanation:
The Ph of bady fluids have different ranges but it should be nearly constant to maintain the health of the human, The PH of the human blood is from 7.35 to 7.45 and the other blood fluids have different ranges . The PH shouldn't drop below 6.9 because it is so dangerous for human health and result coma. if there is high value of PH this indicates high numbers of OH- and low value of PH this indicates high numbers of H+
each organ has a certain PH value to do its function very well ,there is an organ needs acidic environment to work well and other organ needs an alkaline environment to do its work.
