What is the formula for this compound?
Delicious77 [7]

Answer:

Symbols: Each capitol letter means that there is a new element

Li2

Cl3

is made of lithium and chlorine

Na2

SO4 is made of sodium, sulfur and oxygen

Chemical Formulas are used to describe a chemical compound, when two or more atoms

combine to form a new substance.

A combination of chemical symbols shows the elements that make up a chemical compound.

The chemical formula for water is H2O

H stands for HYDROGEN.

O stands for OXYGEN.

Subscripts are numbers that come after a symbol and below. Subscripts tell you the number of

atoms of that element. If an element does not have a subscript, then it is understood that the

subscript is 1.

Li2Cl3 has two lithium atoms and three chlorine atoms

Na2SO4 has two atoms of sodium, one atom of sulfur, and four atoms of oxygen

A subscript outside a parenthesis affects all the elements inside the parenthesis. Multiply the

subscript on the outside by the subscript of the atoms on the inside.

Al (SO4)3 has 1 atom of aluminum, 3 atoms of sulfur, and 12 atoms of oxygen.

Coefficients are full size numbers in front of chemical formula. The coefficient multiplies everything

in the formula. It also represents the number of molecules of that compound.

2Na2

SO4 has 4 sodium atoms, 2 sulphur atoms, and 8 oxygen atoms.

2Al (SO4)

3 has 2 aluminum atoms, 6 sulfur atoms, and 24 oxygen atoms

When you count atoms, remember to multiply the coefficient number and the subscript number to find

the number of atoms of that element.

g During the G2 stage of interphase, ___ does not occur. A. organelle replication B. DNA growth C. protein replication D. cell g
ArbitrLikvidat [17]

Answer: DNA growth does not occur

Explanation:

Here, the cell has grown, the DNA has been replicated (this takes place in the S phase of interphase) and its almost time for the cell to divide. Basically, what occurs during the G2 phase (Gap 2 phase of interphase) includes duplication of all proteins and organelles needed later during the process of cell division. Some of these includes assembly of microtubles will later for the spindle structure that that helps in the separation of chromosomes during the M phase but these are produced during the G2 phase.

The cells also continue to increase/grow in size and the volume of the cytoplasm also increase in this phase. There is also a checking where the cell needs to check for the structures and components and to also ensure that they are all present

What term describes the rising and sinking of the lithosphere as material is added or removed?
Margaret [11]
<span>Composition. (We use the crust-mantle-core terminology to describe differences in chemical composition in Earth's interior. We use the lithosphere- asthenosphere terminology to describe differences the physical state and behavior. Note that the boundaries between layers with different compositions do not occur at the same depths as the boundaries between layers with different physical properties. For example, there is a change in composition when passing from crust into mantle. But there is no change in physical state or behavior at this boundary- the uppermost part of the mantle behaves in the same way that the crust does because it is still far enough below its melting temperature to be a rigid, brittle solid. The transition to a softer, more pliable solid occurs further down within the mantle and this change in behavior occurs with no change in composition.)</span>
