This graduated cylinder has numbers representing milliliters. A student says that the volume of the liquid inside is 21.8 millil

iters. What best explains why the student is wrong? 21.8 is at the top of the meniscus, but volume should be measured in the middle of the meniscus. 21.8 is at the top of the meniscus, but volume should be measured at the bottom of the meniscus. Since the lines are only marked with whole numbers, the student must round to a whole number. Since the whole numbers represent milliliters, the student must use a unit smaller than milliliters.

Explanation:

The answer for this question depends on the type of meniscus in the cylinder. If it is an upright meniscus like in water, the reading should be taken at the bottom of the meniscus. However if it is an inverted meniscus like in mercury, the reading should be taken at the top of the meniscus.

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 1 s. what is your acceleration?
GREYUIT [131]
A = change in velocity / time
so change in velocity = 13-7 = 6
so 6/1 =6:
acceleration = 6m/s^2

You are asked to perform a reaction by dissolving hypochlorous acid in water. Based on your understanding of acids, you understa
AnnZ [28]

According to the principle of chemical equilibrium, when additional hypochlorous acid is added, the hypochlorite ion concentration will increase.

<h3>What is chemical equilibrium?</h3>

Chemical equilibrium refers to the equilibrium which exists between chemical species in a reaction such that the rate of forward and backward reactions are the same.

Since the reaction is in equilibrium, when additional hypochlorous acid is added, the hypochlorite ion concentration will increase ad equilibriumwill shift to the right of the reaction.

The strongest intermolecular interactions between hydrogen fluoride (hf) molecules arise from
aliya0001 [1]
Answer:
            <span>The strongest intermolecular interactions between hydrogen fluoride (hf) molecules arise from Hydrogen Bonding.

Explanation:
                   Hydrogen Bond interactions are considered the strongest intermolecular interactions among molecules. These interactions are found between Hydrogen atom of one molecule bonded to most electronegative atoms (i.e F, O, N) and the most electronegative atoms of neighbor molecule.
                  In case of HF, fluorine has the greatest electronegativity of 4, so the hydrogen bonded to Fluorine becomes partial positive and makes Hydrogen bond with Fluorine atom of </span>neighbor HF molecule.<span />
