Answer:

Decomposition Reaction

2 AgCO₃ -----> 2 Ag + 2 C + 3 O₂

Explanation:

During the reaction, the reactant breaks down into smaller elements/compounds. As such, this is a decomposition reaction.

An equation is balanced when there is an equal amount of each element on both sides of the reaction. If these amounts are unequal, you can add coefficients to modify the quantities of particular elements/compounds. These coefficients must be as small as they can be while remaining whole numbers.

The unbalanced equation:

AgCO₃ -----> Ag + C + O₂

Reactants: 1 silver, 1 carbon, 3 oxygen

Products: 1 silver, 1 carbon, 2 oxygen

The balanced equation:

2 AgCO₃ -----> 2 Ag + 2 C + 3 O₂

Reactants: 2 silver, 2 carbon, 6 oxygen

Products: 2 silver, 2 carbon, 6 oxygen

Compare the intermolecular forces, dipole-dipole and hydrogen-bonding. What would you suggest is the biggest different between t

Angelina_Jolie [31]

Both the dipole-dipole and hydrogen are essentially same because they result form formation of partial negative and positive charges on the atoms constituting a given molecule. in such molecule, one atom is more electronegative than the other and therefore pulls the shared electrons more to itself than the other atom. the atom that pulls a pair of electrons more to itself becomes partially negatively charged whereas the other atom becomes partially positively charge. the weak negative charges on one molecule attracts weak positive charge on the other molecule creating intermolecular forces referred to as dipole-dipole bonds. Hydrogen bonds form in the same manner they are stronger than typical dipole-dipole bonds. so according to the explanation above D is the correct answer.

Y = 57.15 − 0.5 X If Y equals 5 , what is X ? Then is Y=3, what is X?

Fiesta28 [93]

When y equals 5, x is 104.3

When y equals 3 then x is 108.3

Solution:

Given expression is:

$y = 57.15 - 0.5x$

<h3>If y equals 5 what is x ?</h3>

Substitute y = 5 in given expression

5 = 57.15 - 0.5(x)

5 = 57.15 - 0.5x

0.5x = 57.15 - 5

0.5x = 52.15

Divide both sides by 0.5

x = 104.3

Thus when y equals 5, x is 104.3

Substitute y = 3 in given expression

3 = 57.15 - 0.5(x)

3 = 57.15 - 0.5x

0.5x = 57.15 - 3

0.5x = 54.15

Divide both sides by 0.5

x = 108.3

Thus when y equals 3 then x is 108.3

A sample of oxygen gas has a volume of 5.60 l at 27Â°c and 800.0 torr. how many oxygen molecules does it contain?

ratelena [41]

1.44x10^23 molecules of oxygen gas The ideal gas law is PV = nRT where P = pressure (800.0 Torr) V = volume (5.60 L) n = number of moles R = Ideal gas constant (62.363577 L*Torr/(K*mol) ) T = absolute temperature (27C + 273.15 = 300.15 K) Let's solve for n, the substitute the known values and solve. PV = nRT PV/RT = n (800.0 Torr*5.60 L)/(62.363577 L*Torr/(K*mol)*300.15 K) = n (4480 L*Torr)/(18718.42764 L*Torr/mol) = n 0.239336342 mol = n So we have 0.239336342 moles of oxygen molecules. To get the number of atoms, we need to multiply by avogadro's number, so: 0.239336342 * 6.0221409x10^23 = 1.44x10^23

Which of the following would help you identify a titration curve that involved a strong acid titrated by a weak base?

Mariulka [41]

Answer:

The pH at the equivalence point is lower than 7

Explanation:

Given the titration involves a strong acid and a weak base

An example is the reaction between ammonia and hydrochloric acid in the aqueous phase

The pH of the base will ordinarily start high and drop rapidly with the additions of acid. As the equivalence point is approached, the pH will change more gradually, until finally one drop will cause a rapid pH transition through the equivalence point.

If a chemical indicator is used—methyl orange would be a good choice in this case—it changes from its basic to its acidic colour.

In strong acid-weak base titrations, the pH at the equivalence point is not 7 but below it. This is due to the production of a conjugate acid during the titration; it will react with water to produce hydronium ions.
