It’s the first 1 M yea it’s the first one
Molar mass HCl = 36.5 g/mol and NaOH = 40.0 g/mol
molarity of NaOH = 1.0 M
Volume of NaOH = 20.00 mL in liters : 20.00 / 1000 = 0.02 L
Number of moles NaOH :
n = M * V
n = 1.0 * 0.02
n = 0.02 moles Of NaOH
Finally Molarity of the <span>acid solution
</span>
Volume HCl : 15.0 mL in liters : 15.0 / 1000 = 0.015 L
1 HCl + 1 NaOH = 1 H₂O + 1 NaCl
1 mole HCl --------- 1 mole NaOH
? mole HCl --------- <span> 0.02 moles NaOH
</span>
moles HCl = 0.02 * 1 / 1
= 0.02 moles of HCl
M ( HCl) = n / V
= 0.02 / 0.015
= 1.333 M of HCl
hope this helps!
Answer:
Carbon Monoxide / Carbon Dioxide / Sulfur and Nitrogen Dioxide
Explanation:
The moving of molecules from areas of high concentration to that of low concentration to gain energy is best described as passive transport
<h3>What is passive transport?</h3>
Passive transport is a type of membrane transport in which chemicals are moved across cell membranes without using energy. Unlike active transport, which uses cellular energy, passive transport uses the second law of thermodynamics to cause the movement of substances across cell membranes.
<h3>Why is passive transport important?</h3>
Passive transport processes are critical to homeostasis. They maintain proper conditions inside the cell and the organism as a whole by letting chemicals to pass into and out of the cell.

The volume shown in the graduated cylinder according to the image would 28 mL. Thus, the correct option would be C.
In the cylinder, the top of the liquid formed a concave meniscus with the walls of the cylinder. Thus, the bottom of the meniscus would be read as this is the normal rule.
The rule is such that for liquids that form concave meniscus with the walls of cylinders, the bottom of the meniscus is read while it is the top of the meniscus for liquids that form convex meniscus with the walls of cylinders.
Hence, looking at the image, the bottom of the concave is on the 28 mL mark on the cylinder.
