Answer:

The equilibrium law

Explanation:

According to the equilibrium law , when $\text{concentration}$ of any of the  reactants or the products in the reaction at an equilibrium state,  is changed, then it changes the composition of equilibrium mixture in order to minimize the effect of

Acetic acid (in excess) + $\text{alcohol}$ ⇄  $\text{ester}$ + water

$\text{Fischer esterification}$ is a reaction which involves the equilibrium. So to force the reaction towards the side of $\text{ester}$, one of the reactant is taken in excess. All this can be explained easily by applying the equilibrium law.

In the lab, you are given a metal ball. You measure the mass of the ball to be 28 g. You place the ball in a graduated cylinder
KIM [24]

Answer:

Density = 8.75ml

Explanation:

Density = Mass / Volume

In this problem ...

Mass = 28 grams

Volume = 31.4ml - 28.2ml = 32ml (water displacement also)

∴Density = mass /volume = 28g/32ml = 8.75g/ml

What is the density of water if you have 50.0 grams of water and a volume of 50.0 millimeters
Gnom [1K]

Answer:

\boxed {\tt 1.0 \ g/mL}

Explanation:

Density can be found by dividing the mass by the volume.

d=\frac{m}{v}

The mass of the water is 50.0 grams.

The volume of the water is 50.0 milliliters.

m= 50.0\ g \\v=50.0 \ mL

Substitute the values into the formula.

d=\frac{50.0 \ g}{50.0 \ mL}

Divide.

d= 1.0  \ g/mL

The density of the water is 1.0 grams per milliliter. Also, remember that the density of pure water is always 1.0 g/mL or g/cm³

Electronegativity is :_______________
bixtya [17]

Answer:

c) the attraction of an atom for the electrons in a covalent bond.

Explanation:

Electronegativity, symbol χ, is a chemical property describing an atom's ability of to attract a shared pair of electrons to itself. It is influenced by the atomic number of the atom and the distance between the valence electrons and the charged nucleus. As the electronegativity number of atoms increases, the more the atom attracts electrons towards itself.
