Final temperature of the aluminum is 41.8 °C

We have the equation for energy

E = mc∆T

Here m = 55 g = 0.055 kg

∆T=T-27.5

Specific heat capacity of aluminum = 921.096 J/kg.K

E = 725 J

Substituting

E = mc∆T

725 0.055 x 921.096 x (T - 27.5)

T-27.5 14.31

T=41.81° C = 41.8 °C

41.8 °C

Final temperature of the aluminum = 41.8°C

A 0.2688 g sample of a monoprotic acid neutralized 16.4 mL of 0.08133 M KOH solution. Calculate the molar mass of the acid
ivanzaharov [21]

Answer:

202 g/mol

Explanation:

Let's consider the neutralization between a generic monoprotic acid and KOH.

HA + KOH → KA + H₂O

The moles of KOH that reacted are:

0.0164 L × 0.08133 mol/L = 1.33 × 10⁻³ mol

The molar ratio of HA to KOH is 1:1. Then, the moles of HA that reacted are 1.33 × 10⁻³ moles.

1.33 × 10⁻³ moles of HA have a mass of 0.2688 g. The molar mass of the acid is:

0.2688 g/1.33 × 10⁻³ mol = 202 g/mol

A. They are the most destructive earthquake waves.

D. They can move in a rolling pattern through rock, like an ocean  wave.

Explanation:

Surface waves are seismic waves that cause the most destruction during an earthquake.

Rayleigh waves are known to cause rolling pattern of rocks just like an ocean waves.

  • Seismic waves are elastic waves that notably transmits energy.
  • They usually accompany earthquakes.
  • There are two broad categories of these waves.
  • Surface and body waves.
  • Seismic surface waves are low frequency and long wavelength waves.
  • They travel very close to the surface.
  • They are made up of Love and Rayleigh waves.
  • Love waves travels laterally in a horizontal fashion.
  • Rayleigh waves rolls like ocean waves in the ground.
  • The bulk of the destruction caused during an earthquakes is due to these waves.
  • They are the last waves to arrive a seismic station
