Group 2 is alkali earth metals
group 17 is halogens
group 18 is noble gasses
group 1 is alkali metals
Answer: 1) C; 2)D; 3)B; 4)B; 5) A
Explanation:Interpreting the following Arterial Blood gases, we have
1. pH 7.33 PaCO2 60 HCO3 34----Respiratory acidosis with partial compensation----C
2. pH 7.48 PaCO2 42 HCO3 30------. Metabolic alkalosis without compensation----D
3. pH 7.38 PaCO2 38 HCO3 24 ----- Normal---B
4. pH 7.21 PaCO2 60 HCO3 24------ Respiratory acidosis without compensation-----B
5. pH 7.48 PaCO2 28 HCO3 20 ----Respiratory alkalosis with partial compensation
The Arterial blood gas interpretation from analysis shows the pH and the partial pressures of oxygen and carbon dioxide in the arterial blood of an individual which can detect how well the lungs are functioning thereby making a physician make a diagnosis, estimate the severity of a condition and profer treatment.
To reiterate the problem, we are asked to find which of the reactants is the limiting one. The reaction is
<span>CH</span>₄<span> + 2 O</span>₂<span> → CO</span>₂<span> + 2 H</span>₂O
We have an initial amount of 3.05 mol CH₄. Let's see how much of oxygen is required for this:
Theoretical mol O₂ required = 3.05 mol CH₄ * 2 mol O₂/1 mol CH₄ = 6.1 mol
However, the initial amount of oxygen is only 5.03 mol, which is not enough for the theoretical value. <em>Therefore, the limiting reactant is oxygen.</em>
Answer:
Pressure = 0.5 atm
Explanation:
Data;
V1 = 5.0L
P1 = 1.0atm
P2 = ?
V2 = 10L
From Boyle's law, the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.
Mathematically,
V = k / P
k = V1 * P1 = V2 * P2 = V3 * P3 =.........= Vn * Pn
P1 * V1 = P2 * V2
(1.0 * 5.0) = (P2 * 10)
5 = 10P2
P2 = 5 / 10
P2 = 0.5atm
The new pressure of the gas is 0.5atm
