Solutions with low pH values have which of these properties?
telo118 [61]

Answer:

The correct option is C.

Solutions with low pH values have sour taste.

Explanation:

Low pH value show acidic property which can be define as , -log of conc. of hydrogen ion.

Acid has following properties

  • Sour taste
  • Turn blue litmus into red
  • corrosive

-OH group: Base have OH groups. So it is not correct option so it not correct for low pH i.e. acid

turns litmus paper blue: Base turn red litmus into blue, so it not correct for low pH i.e. acid

feels slippery: Bases are mostly slippery like soap

tastes sour: Sour taste is for acid and bitter taste is for base. So it is correct option for acid

If the density of a 45.0 cm3 block of wood is 0.65 g/ml what is the mass of the wood?
wlad13 [49]

Answer:

\boxed {\tt mass=29.25 \ grams}

Explanation:

The density formula is mass over volume.

d=\frac{m}{v}

Rearrange the formula for the mass, m. Multiply both sides of the formula by v.

d*v=\frac{m}{v}*v

d*v=m

Mass can be found by multiplying the density and volume. The density is 0.65 grams per milliliter and the volume is 45.0 cubic centimeters.

  • A cubic centimeter is equal to a milliliter.
  • Therefore, 45 cubic centimeters also equals 45 milliliters.

d= 0.65 \ g/mL\\v= 45 \ mL

Substitute the values into the formula.

0.65 \ g/mL * 45 \ mL=m

Multiply. Note the milliliters, or mL will cancel out.

0.65 \ g * 45=m

29.25 \ g=m

The mass of the wood is 29.25 grams.

The solutions that are mixed contain agno3 and nacl. What two products can be formed by exchange of the ions from these two reac
anastassius [24]

Answer:

NaNO₃ and AgCl are the two products that can be formed.

Sodium nitrate, an aqueous solution and a solid silver chloride (precipitate)

Explanation:

We determine the dissociation of both salts

AgNO₃ (aq) → Ag⁺ (aq) + NO₃⁻ (aq)

NaCl (aq) →  Na⁺ (aq) + Cl⁻ (aq)

We make the ionic equation:

Ag⁺ (aq) + NO₃⁻ (aq) + Na⁺ (aq) + Cl⁻ (aq) → NaNO₃(aq) + AgCl (s) ↓
