What does the conversation of mass say about the amount of atoms in the reactants compared to the products?

Answers

Answer 1

Answer:

the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

Answer 2

Answer:

[tex]\boxed {\boxed {\sf Atoms \ in \ reactants \ = atoms \ in \ products}}[/tex]

Explanation:

The Law of Conservation of Mass states that mass cannot be created or destroyed.

In a chemical reaction, this means the mass of the reactants (substances going in and being changed) must equal the mass of the products (new substances from the reaction).

In addition, the amount of atoms must stay the same. The atoms can and will reconfigure to form different compounds, but the number of atoms stays the same.

The cells in the human body are like little factories. In order to grow, repair, and live, the cells need supplies. Which body systems help these cells get the energy they need?
A) circulatory system and immune system

B) digestive system and excretory system

C) circulatory system and digestive system

D) respiratory system and excretory system

Answers

Answer: A) circulatory system and immune system

Circulatory system and digestive system are the body systems which will help these cells get the energy they need.

What is Digestive system?

These are parts of the body which are involved in the breakdown of food to form energy and other compounds.

Circulatory system on the other hand ensures the nutrients are transported to other parts of the body which is why option C was chosen.

How do matter and energy move through an ecosystem?
My scientific explanation is:

Your answer should include at least 6 complete sentences to explain the claim, evidence and reasoning.
Be sure to check your grammar and spelling.

Answers

Food chains allow energy to move through an ecosystem. For example, energy is transferred from organism to organism such as the sun gives energy to grass, grass gives energy to grasshoppers when they eat grass, mice eat grasshoppers, and snakes eat mice, eagles or bigger birds of prey eat snakes. A technique discovered by Charles Elton named energy pyramids display how energy is dispersed on a pyramid starting from producers to tertiary consumers. An example of a producer would be grass, primary consumer would be a grasshopper (herbivores), a secondary consumer would be a mouse/mice (eat herbivores), and a tertiary consumer (eat secondary consumers) would be an owl. Starting from the bottom of the energy pyramid (producers) to the top (tertiary consumers) it 10% of energy is available to travel up the pyramid. That is your scientific explanation!

At room temperature, aluminum is a solid and water is a liquid. How do the particles of the solid aluminum compare to the particles of the liquid water?

What causes the electrons to move and form static electricity?
moist air

friction

Answers

Answer:

friction

Explanation:

The rubbing of certain materials against one another can transfer negative charges, or electrons.

The friction generating between the surface of two objects causes the electrons to move from one body to the other and form static electricity. Hence, option c is correct.

What is static electricity ?

Static electricity is the flow of electrons that occurs due to the temporary polarization of two bodies. When a conducting surface rub on other surface, they gets electrons by frictional force.

These free flow of electrons make them negatively charged. When this negatively charged body comes in contact with a non conducting surface they latter gets polarized by the electrons of negatively charged body.

The positive charges of the nonconducting surface gets attracted to the negative body and the electrons flow from the negatively charged body to the partially polarized positive body. This is called static electricity.

Step-by-step explanation:

1)When ever an acid reacts with baking soda brisk effervescence of carbon dioxide gas are released.

So, when citric acid reacts with baking soda it gives salt of sodium citrate , water and carbon dioxide gas.

2)

According to law of conservation of mass:

Number of atoms on reactant sides are equal to the number of atoms on product side.

Number of atoms of an element on left hand side is equal to the number of atoms of that same element on the right hand side.

Number of hydrogen atom on reactant side = 5

Number of hydrogen atom on product side = 2+ x

5 = 2+x

x = 3

Number of carbon atom on reactant side = 3

Number of carbon atom on product side = 1 + y

3 = 1 + y

y = 2

Number of oxygen atom on reactant side = 5

Number of oxygen atom on product side = z + 3
