Yes it is option D
simply if 1 mole of H2SO4 require 2 moles of NaCN, i.e. the double amount. so 3.6 moles will require 7.2 moles of NaCN

2.50 L of gas originally at 50 K is warmed to 80 K. If the pressure remains constant, which gas law needs to be used to find the

Brilliant_brown [7]

Answer:

Explanation:

You want an equation that includes both V and T. Charles' Law states that V =kT or V₁/T₁ = V₂/T₂, so this is the best formula to use.

B: The Combined Gas Law is p₁V₁/T₂ = p₂V₂/T₂ will work, but it's overkill for the situation. You can assume any constant value for the pressure, and it will cancel from each side of the equation,

C is wrong. Boyle's Law is p₁V₁ = p₂V₂. It does not include the temperature.

D is wrong. Gay-Lussac's Law is p₁/T₂ = p₂/T₂. It does not include the volume.

8. Balance the following nuclear equations:<br> ^65/30Ca -> ^65/29Sc +_______

a_sh-v [17]

Explanation:

⁶⁵₃₀Ca → ⁶⁵₂₉Sc + ⁿₓH

The reaction above is nuclear reaction.

In a nuclear reaction, the mass number and atomic number must be conserved.

The mass number is the superscript before the atom

Atomic number is the subscript before the atom

Conserving mass number:

65 = 65 + n

n = 0

conserving atomic number:

30 = 29 + x

x = 1

The unknown atom is a positron i.e a positively charged electron: ⁰₁e

⁶⁵₃₀Ca → ⁶⁵₂₉Sc + ⁰₁e
