Balancing chemical reactions is consistent with which scientific law?

Chemistry

Answer:

Balancing chemical reactions is consistent with Lavoisier's law of conservation of mass.

Explanation:

When a chemical reaction happens, involves the exchange of electrons between the different elements inside the compounds that participate in the reaction.

But the elements themselves (that form the compounds) are not affected , so the elements that are after the reaction should be the same ones that before it happens.

Therefore the total mass of an element (sum of the mass of all the atoms of an element that appears before the reaction) should be the same as the total mass of the element after the reaction. And this should be true for each element.

Lets take this example of a balanced chemical reaction

N_{2}+ 3H_{2} -> 2NH_{3}

the number of N atoms at the beggining is 2 ( 2 N atoms attached to themselves) and after the reaction are 2 N also ( each one bonded to an ammonia molecule)

The same should happen with H : 3 gas molecules x 2 atoms of H per gas molecule (H2) = 6 and after the reaction 2 ammonia molecules x 3 atoms of H per ammounia molecule = 6

The equation is balanced only when all the elements are balanced

Note: Strictly speaking, the sum of energy and mass is conserved. But the correction is so insignificant for chemical reactions that in the majority of cases is not taken into account.

Give the clarification of heat and temperature on the basis of molecular motion?
sdas [7]

Explanation:

Heat is a form of thermal energy.

Heat is the sum of all the energy of the molecular motion in an object.

Temperature measures the average heat possessed by each molecule in a given substance.

 Molecules at a higher temperature possess more kinetic energy and they will move faster. This kinetic energy form is the heat variant of thermal energy.

Temperature is the measure of this heat energy of molecules.

The order of a reaction Z1) is the product of the powers to which the reactant concentrations are raised in the rate law. Z2) ca
irinina [24]

Explanation:

The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant.

The overall order of reaction is the sum of the individual orders of reaction with respect to the reactants.

Rate = k [A]²[B]¹

In the rate law above, the rate is second order with respect to A and first order with respect to B. The overall order of reaction is a third order reaaction given as; 2+ 1 = 3

Are Zombies Living or Non-living Reasoning and Evidence?
Thepotemich [5.8K]

Answer:

I believe that zombies are not living

Explanation:

because zombies don't grow and develop because they are practically mindless. Also, zombies definitely respond to the environment (like when they see a human) but they don't adapt to it
