What property of metals allows them to be shaped into wires?

Chemistry
1 answer:
Andreas93 [3]2 years ago
4 0

Answer:

Ductility

Explanation:

Ductility is the ability of a metal to be converted into a thin wire without  getting break and loosing its hardness. The property of Ductility of a metal allows us to make a wider use of them. Some most ductile metals are gold, silver, copper etc. whereas some of the metals with very less ductility are tungsten, steel and other alloys as they are very hard to transform into a thin wire.

A metal with less ductility can be malleable as it can have the ability to be converted into a thin sheet. Not all the metals are ductile but some of them have high ductility, some have less and some of them are non ductile.

What is the ph of a buffer consisting of 0.200 m hc2h3o2 and 0.200 m kc2h3o2? the k a for hc2h3o2 is 1.8×10−5. view available hi
AURORKA [14]
PH = pKa + log \frac{[base]}{[Acid]}
Acid  is HC₂H₃O₂ and conjugate base is KC₂H₃O₂,
pKa = - log Ka = - log (1.8 x 10⁻⁵) = 4.74
so pH = 4.74 + log (0.2/0.2) = 4.74
This is called maximum buffer capacity (when acid conc. and base conc. are equal) the pH = pKa in this case

Predict the final temperature of 3.50 kg of water in a calorimeter if the water is at 27.5°C before 0.77 oz of noodles containin
BaLLatris [955]

The final temperature of the water is determined as 50.55 ⁰C.

<h3>Final temperature of the water</h3>

The final temperature of the water is determined from the following calculations;

Q = mcΔθ

Δθ = Q/mc

where;

  • Q is the amount of energy = 81 kcal = 338904 J
  • c is specific heat capacity of water = 4,200 J/kgC

Δθ = 338904 /(3.5 x 4200)

Δθ = 23.05 °C

Final temperature = T₁ + Δθ

Final temperature = 27.5°C + 23.05 °C = 50.55 ⁰C.

A base has a molarity of 1.5M w.R.T the hydroxyl ion concentration. If 7.35 cm3 of this base is taken and diluted to 147 cm3, th
daser333 [38]

Answer:

0.077M is the concentration of the hydroxyl ion

Explanation:

Dilution factor is the ratio between the aliquot that is taken of a solution and the total volume of the diluted solution.

For the problem, dilution factor is:

7.53cm³ / 147cm³ =<em> 0.05122</em>

To obtain molarity of a diluted solution you must multiply dilution factor and initial molarity of the solution, thus:

1.5 M × 0.05122 = <em>0.077M is the concentration of the hydroxyl ion</em>

Whats is a chemical change of a paper bag
DanielleElmas [232]
Combustion will cause a chemical change in paper.

This is because the carbon compounds are being oxidized into carbon dioxide and water vapour (or h2o, same thing).
