how does a balanced chemical equation represent the conservation of matter in a chemical reaction?
a. the type of matter in the products is different from the type of matter in the reactants.
b. there are more atoms in the reactants than in the products.
c. there are fewer atoms in the reactants than in the products.
d. the number of atoms of each element in the reactants equals the number of atoms of each element in the products.
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.

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.

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

Why does a car’s engine become hot while it is running?
Answer:
Engines can overheat for many reasons. In general, it's because something's wrong within the cooling system and heat isn't able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.
Explanation:
HOPE IT WILL HELP U
Answer:
There might be some problem in the engine's cooling system.
Explanation:
There are many reasons why your car could be overheating, but the basic process of overheating involves a problem with the vehicle's cooling system that doesn't allow heat to leave the engine compartment. This is often due to a leak or blockage somewhere in the engine cooling system or other components.

Zinc chloride (ZnCl2) is used as a flux when joining metals. It also is used to fireproof and remove odor from clothing. Reacting the metal zinc (Zn) with hydrochloric acid (HCl) to produce zinc chloride and hydrogen (H2). Use the models above to demonstrate that mass is conserved when zinc reacts with hydrochloric acid.
Answer:
The atoms are just rearranged but there is no decrease or increase in the mass. A law fo conservation.
Explanation:
For my science class, we were doing Savvas too so I know the answer for this question.
According to the law of conservation of mass and as depicted in the model there are equal number of atoms of reactants and products , thus demonstrating that mass is conserved.
What is law of conservation of mass?According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.
