Beryllium (Be) is the only alkaline earth metal that does not react with water.

What are alkali metals and their properties?

Alkali is a substance that produces hydroxide ions in aqueous solution.

PHYSICAL PROPERTIES OF ALKALIS:

  • Alkalis have a BITTER taste & have a SOAPY touch.
  • Alkalis turn RED litmus paper BLUE.
  • Alkalis have a pH value > 7.
  • Alkalis are CAUSTIC.
  • Alkalis CONDUCT ELECTRICITY due to the presence of MOBILE IONS in solution.

CHEMICAL PROPERTIES OF ALKALI METAL

  • Alkalis react with Acids to form salt and water. This reaction is called neutralisation reaction.
  • Alkalis react with ammonium salts to form salt, water and ammonia gas. .
  • Alkalis react with solution of metal salt to form another metal salt and hydroxide.

Beryllium (Be) is the only alkaline earth metal that does not react with water.

The electrical generators can provide 1.5 × 109 W of power for a maximum of 5 hours. Calculate the maximum energy that can be tr
hoa [83]

The maximum energy that can be transferred by the electrical generator is  2.7×10¹³ Joules.

We can use the equation of electric power and electric energy.

Electric Power: This can be defined as the ratio of the electric energy to the time of electrical equipment.

⇒ Formula

  • P = E/t............... Equation 1

⇒Where:

  • P =  Maximum electric power
  • E =  Maximum electric Energy
  • t = time.

make E the subject of the equation

  • E = Pt................. Equation 2

From the question,

⇒ Given:

  • P = 1.5×10⁹ W
  • t = 5 hours = (5×60×60) seconds = 18000 seconds = 1.8×10⁴ s

⇒ Substitute these values into equation 2

  • E = (1.5×10⁹)(1.8×10⁴)
  • E = 2.7×10¹³ Joules.

Hence, the maximum energy that can be transferred by the electrical generator is  2.7×10¹³ Joules.
