Volume = 0.50 L
Molar mass KBr = 119.002 g/mol
Molarity = 0.125 M
Mass ( KBr) = ?
mass = molarity * molar mass * volume
mass = 0.125 * 119.002 * 0.50
mass = 7.437625 g of KBr
hope this helps!

The complete question is:
Question: What disorder is indicated by these findings? A client comes to the emergency department with status asthmaticus. His respiratory rate is 48 breaths/minute, and he is wheezing. An arterial blood gas analysis reveals a pH of 7.52, a partial pressure of arterial carbon dioxide (PaCO2) of 30 mm Hg, PaO2 of 70 mm Hg, and bicarbonate (HCO3−) of 26 mEq/L.
A. Metabolic acidosis
B. Respiratory acidosis
C. Metabolic alkalosis
D. Respiratory alkalosis
Answer: The correct answer is:
D. Respiratory alkalosis
Explanation:
In Respiratory alkalosis the Partial Pressure of Arterial Carbondioxide (PaCO2) become decreased (i.e. less than 35 mm Hg) and the pH of blood become increased (i.e. more than 7.45). Alveolar hyperventilation causes respiratory alkalosis.
Alveolar hyperventilation occurs when alveolar ventilation is increased than the arterial carbondioxide tension and carbondioxide production.
Alveolar ventilation is the gaseous exchange between alveoli and the external environment.
Whereas, in metabolic acidosis, bicarbonate (HCO3) become decreased (i.e. less than 22 mEq/l and the pH of blood become decreased (i.e. less than 7.35); in respiratory acidosis, the pH of blood also become decreased (i.e. less than 7.35) and the PaCO2 become increased (i.e. more than 45 mm Hg); and in metabolic alkalosis, the bicarbonate (HCO3) become increased (i.e. more than 26 mEq/l and the pH become increased (i.e. more than 7.45).
Answer:
A. CaO
Explanation:
Reactant are the species that take part in and also undergoes the reaction to form species which are known as products.
Symbolic representation of the chemical reaction with the help of the formulas and symbols is known as chemical equation. In the chemical equation, reactants are written at left-hand side as well as products are expressed or written on right-hand side. The coefficients which are written before the formulas or the symbols are known as stoichiometric numbers.
Thus, in the reaction shown below:-
<u>Thus, The product of the reaction is:- CaO</u>
Noble gases:) they are very non-reactive
Answer:
other planets and moons in the solar and beyond
Explanation:
NASA aims to find other planets and moons in our solar system, study them comparatively to earth and see if there's a possibility of been colonized by humans.
