Explain how the models you developed show that when methane combines with oxygen to form carbon dioxide and water, no atoms are left over from the reaction.
Answers
Answer: the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide
Explanation:^
From the law of conservation the reactant and product will be always same, that is no atom is extra added or no atom is left over.
What is law of conservation?
The Law of Conservation of Mass basically states that matter can neither be created nor destroyed.
From the reaction, we can see that left hand side are reactant and right hand side is products. In left side 1 carbon, 4 hydrogen, and 4 oxygen. Right hand side 1 carbon, 4 oxygen, 4 hydrogen.
Mathematically, we can say that- LHS = RHS
The arrow mark represent the reaction runs forward direction, methane gas combustion with oxygen to produce carbon dioxide and water.

The chemical reaction is the combination of atomic orbitals of different or same elements. The new product formed can be a molecule or compound which is having different physical and chemical properties than the initial substances.
What are chemical reactions ?A chemical reaction is a chemical change that make the formation or breaking or both of chemical bonds. There are different types of chemical reactions such as synthesis reactions, decomposition, combustion, displacement reaction etc.
The product of these reactions depends on how the elements in the reactant side reorganize. The physical and chemical properties of the new product will be different from that of the initial substance.

Answers
Answer: When one thing in a electric circuit stops working, the whole circuit stops working.
Explanation:
The circuit in series works in a manner that, when one thing stops in the circuit, the whole circuit stops.
What is a circuit?A circuit is the way of passage of electricity including the electrical devices, electrical wires, energy source such as battery etc. There are two types of circuits namely parallel circuit and series circuit.
In a parallel circuit, all the components are arranged in a parallel fashion. For instance if there are three resistors, each resistors will be parallel each other resistors.
In series circuits, all electrical components are arranged in a series. Thu for a group of bulbs, the second tail of first bulb is connected to the first tail of second bulb and so on. So that, the the effect of electrical current will be same for all.

3.What kind of weather occurs after a warm front passes through an area?
Answers
Answer:
1. tropical storms and hurricanes
2.After a cold front moves through your area, you may notice that the temperature is cooler, the rain has stopped, and the cumulus clouds are replaced by stratus and stratocumulus clouds or clear skies.
3.Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface.
