Use the balanced equation of a nitrogen cycle pathway below to support the conservation of matter and energy. n2 + 8 h --> 2 nh3 + h2

Explanation :

Given equation

This equation is balanced. because the number of reactants is equal to the number of products.

According to conservation of matter and energy,

The conservation of matter and energy states that matter can not create and can not  destroy but conserved. we can only change one form to another form of the matter and energy.

So, we can say energy conserved and the ,mass of the system always same over time.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
