quester [9]3 years ago
6 0

Answer:

For 2. the answer is 15.0 mL

For other examples, you can solve by exact way as I have solved the 2nd example.

I have writen down all the balanced chemical reaction equation for examples 1, 3, 4, 5 for you. ( picture 2 )

Explanation:

Please see the step-by-step solution in the picture attached below.(picture 1)

Hope this answer can help you. Have a nice day!

1. Determine if the following statements are true or false (each question is worth one point). The rate law for an overall react
Basile [38]

Answer:

1. F

2. F

3. F

Explanation:

<em>Determine if the following statements are true or false. </em>

  1. <em>The rate law for an overall reaction can be written using the coefficients from the overall reaction.</em> FALSE. The rate law includes the reaction orders, which have to be determined experimentally and may or may not be equal to the coefficients of the overall reaction.
  2. <em>The rate-determining step of the reaction is always the first step of the reaction.</em> FALSE. The rate-determining step is always the slowest step.
  3. <em>A catalyst is a species that is added to the reaction, lowers the activation energy of a reaction, shows up in the rate law (most of the time), and will be in the overall balanced equation.</em> FALSE. A catalyst does lower the activation energy of the reaction, but it doesn't show up in the rate law nor the overall balanced equation.

Which statement correctly compares the thicknesses of Earth’s layers? Earth’s mantle is thinner than its oceanic crust. Earth’s
Harman [31]

“The Earth’s lithosphere is thinner than its asthenosphere”, the statement correctly compares the thicknesses of Earth’s layers

Answer: Option D

<u>Explanation: </u>

The outermost parts of the Earth composed of crust and a part of the upper mantle is termed as lithosphere. And asthenosphere is positioned below lithosphere. The bottom layer of lithosphere has the parts of the upper crust.

So the highly viscous and ductile region in the remaining part of the upper crust forms the asthenosphere below the lithosphere. The upper crust in the lithosphere region contain elastic properties while the upper crust in the asthenosphere is ductile in nature. Thus the statement that lithosphere is thinner than asthenosphere is true as it is located at the surface.

A person uses 770 kcal on a long hike. Calculate the energy used for the hike in each of the following energy units.
Pavlova-9 [17]

Explanation:

1 Cal of energy is equivalent to 4.184 Joules.

A.

770Cal of energy = 3221.680 joules

Therefore, 780kCal of energy = 3221680 Joules.

B.

3200000 Joules (in 2 s.f).

C.

I000 joules = 1 kJoule

3221680 joules = 3221.689 kJoules.

D.

3200 kJ (in 2 s.f).
