Answer:
B.) The coefficients give the molar ratio of the reactants.
Explanation:
The coefficients represent how many of each molecule are within a reaction. Coefficients are added to make sure the amounts of each element are the same on both sides of the reaction. You can use the coefficients to convert between moles of each molecule. As such, the best answer is B.) because coefficients are what allow you to construct a mole ratio.
Answer:
High partial pressure of oxygen in the tissues.
Explanation:
Hemoglobin is a protein found in the red blood cells that is responsible for the transportation of oxygen from the lungs to the rest of the tissues in the body. The partial pressure determines whether oxygen is loaded or unloaded into the hemoglobin.
When there is lack of oxygen in our bodies, we experience hypoxia.
I’m sorry but I cannot see the picture
Answer:
11.31 g.
Explanation:
Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.
M = (no. of moles of solute)/(V of the solution (L)).
<em>∴ M = (mass/molar mass)of NaCl/(V of the solution (L)).</em>
<em></em>
<em>∴ mass of NaCl remained after evaporation of water = (M)(V of the solution (L))(molar mass)</em> = (0.45 M)(0.43 L)(58.44 g/mol) = <em>11.31 g.</em>
Answer:
Matter is a physical substance that contains mass. A substance is a particular kind of matter with uniform chracteristics.
Explanation:
Remeber that matter is anything that has mass and takes up space :)
