If you could interview the author of this article, what questions would you ask in order to clarify evidence about the factors that have caused the rise in global temperatures?
Answer: how many industries and factories are in 'x' country.
Explanation: the main causes of global temperature rising are factories because, harmful gases can be released. And if the number of the factories increase the percentage of the harmful gas that is being released also increases. So to clarify evidence you can ask :- how many factories does country 'x' have?
By the way 'x' means any one country.

Explain how the model you developed shows that when oxygen combines with hydrogen to form water, no atoms are left over from the reaction.
Enter Text
The making of any compound requires the joining of a different element with the help of various bonds, these bonds are as follows:-
Covalent bondIonic bondSigma bondAccording to the question, the atoms of oxygen and the hydrogen molecules joins together in their vacant space and join together with the help of a covalent bond.
The bond changes the physical state of the element and together they form a liquid which is water.

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.
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.

A silver ring reacts with compounds containing sulfur in the air to form silver sulfide, a black substance that makes up the tarnish on the surface of silver objects. To remove that tarnish from the ring, students placed it in a pan lined with aluminum foil and added hot water. Baking soda was added to the hot water and stirred. Students made observations about the process. Which observation of this process provides evidence of a chemical reaction? *
A- Hot water heated the aluminum foil
B- The liquid solution changed color
C- The pan was lined with aluminum foil
D- The hot water cooled
Answer: B
Explaination: The liquid solution changed color means is turned into a different substance with different properties. It is chemical change .
Liquid solution changed color provides an evidence of a chemical reaction as it is accompanied by a chemical change.
What is a chemical change?Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical changes:
1) inorganic changes
2)organic changes
3) biochemical changes
During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

A toy truck falls off a table. As it falls, the toy truck has potential energy and kinetic energy.
Explain how the toy truck can have potential and kinetic energy at the same time.
As the toy falls off a table, it can have potential and kinetic energy at the same time because of the height (h) and velocity (v) of the object, respectively.
When the truck falls off a table it has potential energy (P) and kinetic energy (K) given by:
[tex] P = mgh [/tex] (1)
[tex] K = \frac{1}{2}mv^{2} [/tex] (2)
Where:
m: is the mass of the toy
g: is the acceleration due to gravity
h: is the height of the table
v: is the velocity of the toy
Kinetic energy (equation 2) is related to the velocity (v) of the moving toy while it is falling from the table.
Potential energy (equation 1) is due to the gravitational acceleration (g) exerted on the toy when it is at a height (h) above the table. This energy decreases as the object approaches the ground (where "h" is zero).
Therefore, the truck can have potential and kinetic energy at the same time because of the height and velocity of the toy, respectively.

What defines an interaction between two substances as a chemical reaction is when one or more new substances form from one or more other substances.
What new substances were formed?
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

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.
The interaction of two atoms can be of different types depends on their nature and can bond through ionic bonding, covalent bonding, hydrogen bonding etc.

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.
Therefore, in a series circuit When one thing stops working, the whole circuit stops working.

1.What are two factors that are necessary for hurricane development?
2.What kind of weather occurs after a cold front passes through an area?
3.What kind of weather occurs after a warm front passes through an area?
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.
