Explanation:
An active ingredient sodium hypochlorite which gives the name to the compound bleach has both Hydronium ions and Hydroxide ions . In case of the hydronium ions the number of Ions that is present in bleach is About 1 /10 -12 while in case of Hydroxide ions the number of Ions present in breach are about 1/10-2 ions.
Hence from the numbers we can say the number of Ions that are more in bleach is that of hydroxide having a difference of about 10 ions.
Answer:
4.525% is the percentage by volume of oxygen in the gas mixture.
Explanation:
Total pressure of the mixture = p = 4.42 atm
Partial pressure of the oxygen =
Partial pressure of the helium =
(Dalton law of partial pressure)
According Avogadro law:
(At temperature and pressure)
Volume occupied by oxygen gas =
Total moles of gases = n = 1 mol
Total Volume of the gases = V
Percent by volume of oxygen in the gas mixture:
Answer:
The correct answer is c) directly binding to heme Fe in the oxygen binding site of the hemoglobin.
Explanation:
Carbon dioxide is the waste product of cellular respiration.Carbon dioxide bind to hemoglobin to form carbaminohemoglobin in which the hemoglobin exist as T state or Tensed state.
Carbon dioxide interact with the oxygen binding site of hemoglobin thus decreasing the affinity of hemoglobin for oxygen.
Answer:
Na+ ions diffusing across the membrane through leakage channels the generation of local currents
Explanation:
An action potential occurs when the membrane potential of a specific cell location rapidly rises and falls. There is a voltage difference between the exterior and interior of the cell, called the membrane potential, due the Na+/K+ ATPase pump.
Starting from the resting potential, the action potential starts when the thershold is reached when Na+ ions difusse across the membrane through channels.Then, the interior of the cell becomes positive and the exterior negative.
The K+ channels take place when the repolarization phase stars, letting K+ ions difusse from the inside of the cells to the exterior.
a thin solid glass rod that is used in chemistry to combine substances. A stirring rod often has rounded ends and is about the length of a long straw.
<h3>What use serves the stirring rod?</h3>
A crucial component of lab apparatus for mixing chemicals and liquids for reactions is a long, thin stirring rod. Stirring rods are made of solid plastic, glass, or steel and are non-abrasive, chemically inert, and chemically resistant.
<h3>What is the name of the glass stirring rod?</h3>
Glass rod, also known as a stirring rod, stir rod, or solid glass rod, is frequently made of quartz and borosilicate glass. Its diameter and length can be modified to meet your needs.
<h3>Does filtration employ stirring rods?</h3>
When the liquid transfer procedure is paused, use a stirring rod to direct the liquid flow into the funnel and stop small amounts of liquid from dribbling down the beaker's outside.
