Answer:
T₂ = 51826.1 K
Explanation:
Given data:
Initial Volume = 2.3 L
Final volume = 400 L
Initial temperature = 25 °C (25+ 273 = 298 K)
Final temperature = ?
Solution:
V₁/T₁ = V₂/T₂
T₂ = V₂ T₁/V₁
T₂ = 400 L . 298 K / 2.3 L
T₂ = 119200 K. L / 2.3 L
T₂ = 51826.1 K
Answer:
Ionic bond is bond between a metal and non metal , metallic bonding happens between positive metals ions and negative electrons in a metal
Explanation:
ionic Bond is the transfer of electrons between a metal and non metal due to strong electrostatic force of attraction between positive metal ions and negative non metal ions
in metallic bonding , there is a force of attraction between positive metal ions and the sea of electrons surrounding it
Answer:
B is CH₃-CH₂-CH₂-CH₂-C(triplebond)CH (1-hexyne)
C is CH₃-CH₂-CH₂-CH₂-C(triplebond)C-CH₃ (2-heptyne)
Explanation:
Answer:
C.
Explanation:
The increase the [H+] (concentration of H+ ions)
However, they decrease the pH if acids are added to any solution. Since they have more [H+] ions, they increase their conc. in the solution
Answer:
Number of moles = 0.1179 (Approx)
Explanation:
Given:
Mass of LiCl = 5 grams
Molar mass of LiCl = 42.39 g
Find:
Number of moles
Computation:
Number of moles = Mass / Molar mass
Number of moles = 5 / 42.39
Number of moles = 0.1179 (Approx)
