Ba(OH)₂ is a strong base, therefore completely ionises in the solution as follows
Ba(OH)₂ --> Ba²⁺ + 2OH⁻
1 mol of Ba(OH)₂ gives out 2 mol of OH⁻
therefore number of OH⁻ moles are twice the amount of Ba(OH)₂ moles in the solution
hence,
[OH⁻] = 2[Ba(OH)₂]
therefore hydroxide ion concentration = 2 x 1.37 x 10⁻⁵ M
[OH⁻] = 2.74 x 10⁻⁵ M
coefficient = 2.74
exponent = -5
Answer and Explanation:
Elisa is feeling tired because she has diabetes - suported: diabetes, in fact, can trigger episodes of extreme tiredness in patients, this tiredness may have been accompanied by dizziness and being.
Elisa is feeling tired because she has anemia. - Supported: Anemia hampers the transmission of oxygen in the blood, which can cause tiredness, weakness and extreme fatigue.

If the pancreas is damaged, insulin may be insufficiently produced, increasing the chance of developing diabetes and causing tiredness.
Elisa is feeling tired because she has asthma - suported: asthma causes breathing difficulties, this can cause tiredness and fatigue.
Answer:
The reference ranges for blood potassium levels are as follows : Adult/elderly: 3.5-5.0 mEq/L or 3.5-5.0 mmol/L (SI units) Child: 3.4-4.7 mEq/L. Infant: 4.1-5.3 mEq/L.
Explanation:
B , your products are on the right side of the reaction. The reactants are on the left side
It will be number 1.
NO loses oxygen ie its being reduced to N2
NH3 gains oxygen atom ie its being oxidised to H2O
