Answer:

(a).

order \: of \: A = 2 \\ order \: of \:B  = 0 \\ rate = k[A] {}^{2} [B]

(b)

0.32 \times  {10}^{ - 3}  = k {(0.12)}^{2} (0.15) \\ k = 0.148 \:  {mol}^{ - 2}  {dm}^{6}  {s}^{ - 1}

(c). The rate increases because kinetic energy of reactant molecules increases.

The gas inside a balloon exerts a pressure of 3atm at 298 K. What is the temperature required to increase the pressure to 6 atm?
podryga [215]

Answer: 596 atm

Explanation:

Given that,

Original pressure of balloon P1 = 3atm

Original temperature of balloon T1 = 298K

New pressure of balloon P2 = 6atm

New temperature of balloon T2 = ?

Since pressure and temperature are given while volume is constant, apply the formula for Pressure law

P1/T1 = P2/T2

3 atm / 298K = 6 atm / T2

To get the value of T2, cross multiply

3 atm x T2 = 6 atm x 298K

3 atmT2 = 1788 atmK

Divide both sides by 3 atm

3 atmT2 / 3 atm = 1788 atmK / 3 atm

T2 = 596 atm

Thus, a temperature of 596 atmospheres is required to increase the pressure to 6 atm.

What is the answer for this question?
emmainna [20.7K]

Hey there!

The more energy a substance is, the more movement it has.

The energy of a substance determines its state of matter.

From least to most energy, it goes solid, liquid, gas.

So it needs to be going from a lower energy state to a higher energy state.

The only one that goes from a lower energy state to a higher energy state is C. H2O (l) --> H2O (g).

Hope this helps!

Which of the following groups of elements are likely to have substances that have both metal and non-metallic properties?
Tom [10]

Answer : Group 14 elements are likely to have substances that have both metal and non-metallic properties.

Explanation :

Metalloid : It is a type of element whose properties lies in between the metals and non-metals.

There are commonly six metalloids : Boron(group 13), Silicon & Germanium(group 14), Arsenic & Antimony(group 15), Tellurium(group 16).

Properties of Metalloids :

  • Metalloids look like metals but behave largely like non-metals.
  • Metalloids are solid, brittle and lustrous.
  • Metalloids has ability to conduct electricity.

Therefore, Group 14 elements are likely to have substances that have both metal and non-metallic properties.
