The statement that correctly explains the molecular structure of water is A. One oxygen (O) and two hydrogen atoms (H2) are joined by a covalent bond.
It cannot be ionic, since ionic bonds tend to be sold at room temperature.
Answer:
P(total) = 978 mmHg
Explanation:
Given data:
Total pressure of gas = ?
Partial pressure of O₂ gas = 200 mmHg
Partial pressure of N₂ gas = 350 mmHg
Partial pressure of He gas = 428 mmHg
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
P(total) = P(O₂) + P(N₂) + P(He)
P(total) = 200 mmHg + 350 mmHg + 428 mmHg
P(total) = 978 mmHg
Answer:Carbs Provide Your Body With EnergyGlucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration. Cells can then use ATP to power a variety of metabolic tasks.
