The answer for the question given is A. Heating with a flame.

One of the processes that cause a chemical change is heating. An example of this is cooking or baking, which causes a permanent chemical change in substances. Also, all of the other choices are examples of physical changes.

If you are operating a power driven vessel that is underway in conditions of restricted visibility, what should you do
swat32
If you are operating a power driven vessel that is underway in condition of restricted visibility, you are expected to do the following: sound prolonged blasts every two minutes. If the vessel is underway but is not moving, it is expected to sound two prolonged blast every two minutes. When one hears any of the signal above, one is expected to reduce speed to the minimum that is needed to keep on course.

The equilibrium constant of a reaction: A) is not related to the change in free energy of the reaction. B) is the same as the ma
Taya2010 [7]

Answer:) is related to the change in free energy of the reaction--d

Explanation:

For any reaction that is taking place at any moment the change in Gibbs Free Energy is related to the reaction quotient as

 ΔG=ΔG⁰+RTlnQ  

where R-Universal Gas Constant, T- Temperature in Kelvin, Q is the reaction quotient

Now when the system is in equilibrum,    ΔG⁰ which is the standard Gibb's Free Energy,is then  defined as

ΔG⁰=−RTlnK ,

where K is the equilibrium constant. because  ΔG becomes 0 and reaction quotient Q = K

The equilibrum constant   is related to the change in free energy of the reaction.

because when  ΔG is negative, the value of K is high which leads to a spontaneous. reaction

when   ΔG is positive, the value of K is low, which leads to a spontaneous. reaction in the opposite direction.

In the reaction N2 + 3H2 - 2NH3, how many
dalvyx [7]

Answer:

B. 2g

Explanation:

So first you have to find the mole to mole ratio then convert it to grams if that makes sense. So the mole to mole ratio is 2 ammonia to 3 hydrogen gas. So then after you do that conversion you can solve for grams then. Sorry I am not that great at explaining.
