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

What are three ways that synthetic materials benefit human society?
Answer:
The benefits in synthetics are many, they have properties that we can't find in nature, they allow us to make things stronger, lighter, more fuel-efficient, shiner, longer lasting. And at the same time, we do add to the pollution of our world, affect the health of animals and humans, and requires energy to make.
Explanation:
Synthetic materials, also known as man-made or artificial materials, have made significant contributions to human society. Like Improved Performance and Durability, Expanded Range of Applications, etc.
Here are three ways in which synthetic materials benefit us:
Synthetic materials often possess superior properties compared to natural materials, such as increased strength, durability, and resistance to wear and tear.
Expanded Range of Applications: Synthetic materials have opened up new possibilities by offering characteristics that may not be readily available in nature.
Resource Conservation and Environmental Benefits: Synthetic materials can help conserve natural resources by providing alternatives to scarce or unsustainable materials.
Thus, while synthetic materials have numerous benefits, it is essential to consider their environmental impact throughout their lifecycle, including disposal and potential hazards.

PREDICT: Which do you think would be the most adhesive and least adhesive to wax paper and why do you think this?
A) oil
B) Isopropyl alcohol
C) tap water
D) soapy water
Answer:
Tap water would be the least adhesive to wax paper.
Oil would be the most adhesive
Explanation:
If you get wax paper and water right now, it will repel the water. Putting wax on anything makes it water repellent. I don't know how but this is just my prediction.
I feel like oil would be the most adhesive because oil repels water, so does wax paper. So I'd predict oil would hold onto wax paper the most.
Hope this helps!

Answer:
C- "able to talk"
Explanation:
Not all living things cant talk, but they all use energy, are made of cells and can reproduce.
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
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?

2. hydrophobic
3. cohesion
4. hydrophilic
5. surface tension
what do you mean by cohesion ?cohesion is an attractive force of measure where molecules are stick to each other and it is caused by cohesive force between like molecules.
It is an intrinsic property of a molecule, derived by its shape, structure, and electric charge distribution.
When cohesive molecules are become closer to each other, the electrical attraction between these molecule holds them together.
This forces are responsible for surface tension. For example mercury is a cohesive substance, strongly attracted to each other, bead together, sticks to itself when it flows.
When cohesion and adhesion combinedly work, it will lead to capillary action.
Hence, when water climbs up the interior of a thin glass tube or the stem of a plant, Cohesion holds the water together and adhesion helps the water molecules stick to glass.

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

In two or more complete sentences, describe how your knowledge of balancing chemical equations can help you to determine the missing compound.
NaHCO3 + HC2H3O2 ⟶ ________ + H2O + CO2
Answer:
1) Carbon dioxide is the name of the gas.
2) The missing compound is
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
5 = z + 3
x = 2
Number of sodium atom on reactant side = 1
