Answer:

(a) Perchloric acid (HClO₄)

(b) Nitric acid (HNO₃)

(c) Bromous acid (HBrO₂)

(d) Phosphoric Acid (H₃PO₄)

Explanation:

Acids are the species which furnish hydrogen ions in the solution. The other specie produced with the hydrogen ion is called its conjugate base.

Thus,

(a) Perchlorate (ClO₄⁻) ion:

The acid that furnish perchlorate ion is <u>perchloric acid (HClO₄)</u>.

(b)  NO₃⁻ ion:

The acid that furnish NO₃⁻ ions is <u>Nitric acid (HNO₃)</u>.

(c) bromite (BrO₂⁻) ion:

The acid that furnish BrO₂⁻ ions is <u>Bromous acid (HBrO₂)</u>.

(d)  H₂PO₄⁻ ion:

The acid that furnish H₂PO₄⁻ ions is <u>Phosphoric Acid (H₃PO₄)</u>.

Dr. Terror has developed a new alloy called Ultranomium. He is testing a bar that is 1.25 m1.25 m long and has a mass of 382 g.3
MrRissso [65]

Answer:0.8742j/g°C

Explanation: SOLUTION

GIVEN

length of bar=1.25m

mass 382g

temperature= 20°C to 288°C

Q=89300J

Specific Heat Capacity  will be calculated using

Q=mC∆T

where

C = specific heat capacity

Q = heat

m = mass

Δ T = change in temperature

C=Q/ m∆T

=89300/382X(288-20.6)

=0.8742j/g°C

Calculate the molarity of a 17.5% (by mass) aqueous solution of nitric acid. Select one: a. 2.74 m b. 4.33 m c. 0.274 m d. 3.04
den301095 [7]

Answer:

Option e.

Explanation:

Molarity is the concentration that indicates moles of solute in 1 L of solution.

We have another concentration, percent by mass.

Percent by mass indicates mass of solute in 100 g of solution.

Our solute is HNO₃, our solvent is water.

17.5 g of nitric acid is the mass of solute. We can convert them to moles:

17.5 g . 1mol / 63g = 0.278 moles

We do not have volume of solution. We assume the mass is 100 g because the percent by mass but we need density to state the volume.

Density = Mass / Volume

Mass / Density = Volume

Once we have the volume, we need to be sure the units is in L, to determine molarity

M = mol /L
