Explanation:
protons, neutrons and electrons
<span>The molar volume of a gas at STP, in liters, is 22.4
you then multiply 22.4 by 2 to get the answer to the next question:
</span><span>
You can use the molar volume to convert 2 mol of any gas to 44.8 L
</span>
<span>You can also use the molar volume to convert 11.2 L of any gas to 0.500 mol.
</span>
Avogadro’s law tells you that 1.2 L of O2(g) and 1.2 L of NO2(g<span>) are the same </span><span>numbers of moles of gas.</span>
Carbon monoxide blocks oxygen in the blood. Hence, option A is correct.
<h3>What is combustion?</h3>
Combustion is a chemical process or a reaction between Fuel (Hydrocarbon) and Oxygen.
During incomplete combustion part of the carbon is not completely oxidized producing carbon monoxide (CO). Incomplete combustion uses fuel inefficiently and carbon monoxide is released.
Carbon monoxide gas diffuses rapidly across the pulmonary capillary membrane, binding to haemoglobin with an affinity 200 times that of oxygen to form carboxyhemoglobin. By displacing oxygen, CO decreases the oxygen-carrying capacity and oxygen delivery to tissues, causing marked cellular hypoxia and acidosis.
Hence, option A is correct.
