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.

When vinegar, an acid, is mixed with baking soda, a base, the reaction is similar to the reaction of Alka-Seltzer and water; a salt, water and carbon dioxide are produced. 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
Number of oxygen atom on product side = a
1 = a
The missing compound is
Explanation:
Answer:
1) Carbon dioxide is the name of the gas.
2) The missing compound is H3C2O2Na

Can someone please explain the cause and effect between the rearrangement of atoms and molecules in a chemical reaction and the different properties that the products have from the reactants.
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. 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.
