Answer:
oxygen and hydrogen
Explanation:
the alcohol group is known as the -OH group, which has oxygen bonded to a hydrogen
Answer: B!
Explanation: In the direction opposite of the direction of the applied force.There is no force in the other side being applied.
Answer : The correct option is, (2) 8 mole of hydrogen will react with 1 mole of sulfur.
Explanation :
The balanced chemical equation is,
By the stoichiometry we conclude that, 8 moles of hydrogen react with 1 mole of sulfur to give 8 moles of hydrogen sulfide.
Hence, the correct options is, (2) 8 mole of hydrogen will react with 1 mole of sulfur.
Initial pressure of the gas = 65.3 kPa
Initial volume of the gas = 654 cm³
Initial temperature of the gas = 6⁰C = 273 + 6 = 279 K
Final pressure of the gas = 108.7 kPa
Final temperature of the gas = 4⁰C = 273 + 4 = 277 K
Using the combined gas law for ideal gases:
P₁V₁/T₁ = P₂V₂/T₂
where P₁, V₁ and T₁ are the pressure, volume and temperature for the initial state and P₂, V₂ and T₂ are the pressure, volume and temperature for the final state.
Plugging the given data into the combined gas law we have,
(65.3 kPa x 654 cm³) / (279 K) = (108.7 kPa x V₂)/(277 K)
V₂ = (65.3 kPa x 654 cm³ x 277 K) / (279 K x 108.7 kPa)
V₂ = 390.1 cm³
water is a major dissolved volatile constituent in both magmas and volcanic gases
