<span>Buffer systems in our
body maintain the pH of blood to be at an optimum level which is at a range of
7.3-7.4. A buffer is a solution that resists changes in pH during the addition
of an acid or a base. Our blood has a number of buffer systems. Examples are
the bicarbonate buffer system and the hemoglobin buffer system.</span>
Answer: In the periodic table the elements are arranged in order of increasing atomic number/ atomic mass from left to right in the periodic table.
Explanation:
The theoretical probability of rolling a two will be 1 in 6 or 1/6 since there is only 1 successful event in 6 possible outcomes when you roll a cube or a dice. When you perform experiments to determine the experimental probability of rolling a two, it will not be the same as that of the theoretical probability not unless you perform the experiment infinite times.
These are structural formulas of constitutional isomers of hexene, an alkene.
Both are acyclic, six-carbon chains, and they differ only in the position of the double bond. As constitutional isomers, both structures have the same molecular formula.
The first structure is of hex-1-ene (or 1-hexene).
The second structure is of (3E)-hex-3-ene [or (3E)-3-hexene].
Both structures have the molecular formula C₆H₁₂.

Answer:
663 g
Explanation:
Step 1: Write the balanced equation
2 LiOH + CO₂ ⇒ H₂O + Li₂CO₃
Step 2: Calculate the moles corresponding to 825 L of CO₂
At standard pressure and temperature, 1 mole of CO₂ has a volume of 22.4 L.
825 L × 1 mol/22.4 L = 36.8 mol
Step 3: Calculate the moles of H₂O formed from 36.8 moles of CO₂
The molar ratio of CO₂ to H₂O is 1:1. The moles of H₂O formed are 1/1 × 36.8 mol = 36.8 mol.
Step 4: Calculate the mass corresponding to 36.8 moles of H₂O
The molar mass of H₂O is 18.02 g/mol.
36.8 mol × 18.02 g/mol = 663 g
