Answer:

HBr + H2O = H3O+ + Br-

So our conjugate acid is the H3O+ to H2O

Explanation:

A conjugate acid of a base results when the base accepts a proton.

Consider ammonia reacting with water to form an equilibrium with ammonium ions and hydroxide ions:

NH3 (aq) + H2O (l) ⇌ NH4+ (aq) + OH- (aq)

Ammonium, NH4+, acts as a conjugate acid to ammonia, NH3.

yaroslaw [1]

Answer:

Explanation:

mole of HCl remaining after reaction with CaCO₃

= .3 M of NaOH of 32.47 mL

= .3 x .03247 moles

= .009741 moles

Initial HCl taken = .3 x .005 moles = .0015 moles

Moles of HCl reacted with CaCO₃

= .009741 - .0015 = .008241 moles

CaCO₃ + 2HCl = CaCl₂ + CO₂ + H₂O .

1 mole 2 moles

2 moles of HCl reacts with 1 mole of CaCO₃

.008241 moles of HCl reacts with .5 x .008241 moles of CaCO₃

CaCO₃ reacted with HCl = .5 x .008241 = .00412 moles

the mass (in grams) of calcium carbonate in the tablet

= .00412 x 100 = .412 grams . ( molar mass of calcium carbonate = 100 )

Give the name of the following molecule. A compound with a total of six carbons with a double bond and the rest single bonds. Th

AlekseyPX

Answer:
The name of given molecule is 3-Methylpent-2-ene.

Explanation:
First of all a carbon chain of five carbons was drawn. Then a double bond was made between carbon 3 and 4 (starting from left). A methyl group was drawn at middle carbon which is at position 3.

Molecule sketched was named as,

1) A longest chain containing double bond was selected and numbering was started from the end closest to double bond. Hence,

2-Pentene or Pent-2-ene

2) The position of substituent was specified before the parent name, Hence,

3-Methyl-2-Pentene or 3-Methylpent-2-ene

which are correct formulas for ionic compounds? for those that are not correct, give the correct formula and justify your answer

skelet666 [1.2K]

Answer:

Ionic compounds have a metal and nonmetal.

Ionic compounds are made up of ions.

Explanation:

You did not provide any formulas for me to correct, but:

ionic compounds tend to have metals and nonmetals. (EX: NaCl)You can look at the periodic table to see which elements are metals and which are not.
ionic compounds are made up of ions. Ions are elements that have a charge (Like $Cu^{2+}$ or $O^{-}$ ). To have a correct ionic compound, make sure that the ions inside of it "cancel" each other out.

EX: Na has a +1 charge. Cl has a -1 charge. When they are paired up, they successfully cancel each other out (become neutral) and become the ionic compound NaCl.

The chart below shows you the charge of each element. Make sure the charge of the elements in an ionic compound "cancel" each other out.

The very last chart shows the metals and nonmetals
