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.
True or False: As air masses move, they rarely change temperatures and/or moisture levels.

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.

Magnesium is a metal with two electrons in its outermost energy level. When it becomes an ion, what happens to its valence electrons? What happens to its charge?
Answer:The answer to your question is Mg loses its valence electrons and acquire a positive charge (Mg⁺²).
Explanation:
Answer:
When it becomes an ion, it donates its valence electrons and becomes positively charged. The positively charged ion would be Mg²⁺ because it loses two electrons. It would have 12 protons and 10 electrons.

What is the relationship between parent cells and daughter cells.
Answer:
Explanation:In particular, eukaryotic cells divide using the processes of mitosis and meiosis. Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell.
A parent cell is the cell that divides during cell division to produce two daughter cells. The two daughter cells produced during mitosis share the same genetic makeup as the parent cell. In meiosis, the daughter cells have half as many chromosomes as the parent cell and a distinct genetic makeup.
What is parent cell ?A parent cell that is a progenitor of other cells or the first in a line of growing cells, as well as a cell that divides to produce two or more daughter cells.
The cell that divides into two daughter cells during cell division is referred to as the mother or parent cell. The mother cell's genetic makeup is carried over into the two daughter cells created during mitosis.
An organism's reproductive cells are called gametes. They are additionally known as sex cells. Male gametes are referred to as sperm, whereas female gametes are referred to as ova or egg cells. Each haploid cell that makes up a gamete has one copy of each chromosome.
Thus, A parent cell is the cell that divides during cell division to produce two daughter cells.

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
