Which of these elements has the second lowest ionization energy? (A) Na (B) K (C) Rb (D) Cs (E) Li
1. Which of these elements has the second lowest ionization energy? (A) Na (B) K (C) Rb (D) Cs (E) Li
Jawaban:
E) Li
Penjelasan:
karena unsur terendah yang kedua adalah unsur yang terkandung didalam ion
2. ionization energy of cl- ion is 349 KJ/mol.Approximate heat liberated when an electron is added to gaseous chlorine atom.
Ionization energy of Cl⁻ ion is 349 kJ/mol. Approximate heat liberated when an electron is added to gaseous chlorine atom is 349 kJ/mol too.
PembahasanEnergi ionisasi ion Cl⁻ adalah 349 kJ / mol. Perkiraan panas yang dibebaskan ketika elektron ditambahkan ke atom gas klor adalah 349 kJ / mol.
Reaksi ionisasi ion Cl⁻ :
Cl⁻ → ¹/₂ Cl₂ + e Energi = 349 kJ/mol
Reaksi penambahan elektron pada atom gas klor :
¹/₂ Cl₂ (g) + e → Cl⁻, maka energi = - 349 kJ/mol
Reaksi ini merupakan reaksi kebalikan dari reaksi ionisasi. Energi ionisasi menyatakan jumlah energi yang menyertai proses pelepasan sebuah elektron.

5. a laptop computer converts 40 J of electrical energy every second. What is its power?
kekuatan in english is powerDik :
W=40 J
t=1 detik
Dit :
P=...?
Peny :
P=W/t
=40/1
=40 Watt
∴ The power is 40 Watt

6. the definition of energy
Energy is the capacity of a physical system to perform work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, electrical, or other forms.
7. What is the difference between kinetic energy and potential energy? a. kinetic energy is stored energy that has the capacity to do work, and potential energy is the energy of motion b. kinetic energy is energy that an object possesses as a result of its location, and potential is the same as heat energy c. kinetic energy can be converted into various forms of energy, whereas potential energy can only be transformed into heat energy d. kinetic energy is energy of a moving object, whereas potential energy is energy possessed by matter as a result of its location or structure e. kinetic energy can be created or destroyed, while potential energy can be created and destroyed
Jawaban:
D
Penjelasan:
energi kinetik adalah energi yang dimiliki oleh benda yang bergerak,sedangkan energi potensial adalah energi yang tersimpan oleh benda berdasarkan letaknya/posisinya
8. Nilai pH of formic acid 0,1 M. Given that ionization constatnt of formic acid is 1×10-7 , the value of pH from formic acid
Penjelasan:
pH = √kb×mb
= √1×10-7×0,1
=√10-8
=10-4
log 10-4 = 4 Maka pH asam tsb= 4
