Which of these statements would be true if the water molecule was linear instead of bent? Check all that apply.
Katen [24]

If the water molecule was linear instead of bent the water would no longer produce hydrogen bonds.

<u>Explanation:</u>

  • Yes, If the water molecule was linear instead of bent the water would no longer produce hydrogen bonds.
  • The water would no longer generate hydrogen bonds.
  • It will lose its polar features and nearly all of its features will change such as boiling point, water tension and solubility.
  • It would be more like to gas, rather than liquid.
  • If the water was in the linear, the water would have all the features and it would produce  the hydrogen bonds.

Under what conditions do real gases behave most ideally.
katrin [286]

Answer:

Under high temperatures and low pressure, gases behave the most ideal.

Explanation:

Low pressure reduces the effect of the finite size of real particles by increasing the volume around each particle, and a high temperature gives enough kinetic energy to the particles to better overcome the attractions that exist between real particles. (Prevents sticking.)

In summary, real gases behave more like ideal gases when they are far away from a phase boundary, (condensation or freezing).

g The decomposition reaction of A to B is a first-order reaction with a half-life of 2.42×103 seconds: A → 2B If the initial con
Tanzania [10]

Answer:

In 23.49 minutes the concentration of A to be 66.8% of the initial concentration.

Explanation:

The equation used to calculate the constant for first order kinetics:

t_{1/2}=\frac{0.693}{k}} .....(1)

Rate law expression for first order kinetics is given by the equation:

t=\frac{2.303}{k}\log\frac{[A_o]}{[A]} ......(2)

where,  

k = rate constant

t_{1/2} =Half life of the reaction = 2.42\times 10^3 s

t = time taken for decay process = ?

[A_o] = initial amount of the reactant = 0.163 M

[A] = amount left after time t =  66.8% of [A_o]

[A]=\frac{66.8}{100}\times 0.163 M=0.108884 M

k=\frac{0.693}{2.42\times 10^3 s}

t=\frac{2.303}{\frac{0.693}{2.42\times 10^3 s}}\log\frac{0.163 M}{0.108884 M}

t = 1,409.19 s

1 minute = 60 sec

t=\frac{1,409.19 }{60} min=23.49 min

In 23.49 minutes the concentration of A to be 66.8% of the initial concentration.
