The name for this W(C2H3O2)4 is the chemical formula for lead(IV) acetate, often known as lead tetraacetate, is Pb(C2H3O2)4.

Chemical formula is defined as any of a number of ways to describe the structure or content of chemical substances. The chemical formula is a way of expressing information about the atomic proportions that make up a certain chemical compound or molecule using the numbers and symbols of the chemical elements. The sorts of atoms and their numbers in a molecule or compound are described using chemical formulae. Each element's atoms are denoted by one or two distinct letters.

It is not a salt because it is a colorless solid that dissolves in nonpolar, organic liquids. Moisture causes it to break down, therefore acetic acid is usually added when storing it. The substance is utilized to create organic compounds.

Thus, the name for this W(C2H3O2)4 is the chemical formula for lead(IV) acetate, often known as lead tetraacetate, is Pb(C2H3O2)4.

photosynthesis (i am not sure of answer choces, but this is the answer

Explanation:

Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. ... Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. I also remember this from Science.

Answer:

-Sulfur is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S₈. Elemental sulfur is a bright yellow, crystalline solid at room temperature.

(Atomic number: 16

Electron configuration: [Ne] 3s²3p⁴

Electrons per shell: 2,8,6

Electronegativity: 2.58)

-Calcium is the 20th element, with 20 protons. Since a stable atom has a net charge of 0, we must have 20 electrons.

-Carbon is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust.

(Symbol: C

Atomic mass: 12.0107 u

Atomic number: 6

Electrons per shell: 2, 4

Electron configuration: [He] 2s22p2

Electronegativity: 2.55)

According to the electronic configuration, number of valence electrons in each atom of calcium,carbon and sulfur is 2, 4 and 6 respectively.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Answer:

Reactants have more energy than products

Explanation:

Generally, in an exothermic reaction heat is released. In other words, energy is released. So you start with reactants which have a set amount of stored chemical energy, and you lose some in the reaction. Since energy is 'leaving', the stored chemical energy in the products is less than what we started with in the reactants. When given a graph, you can tell this is true because going from left to right, the line representing the stored chemical energy will start at a higher level than where it ends.

The true statement about an exothermic reaction is that reactants have more energy than products.

An exothermic reaction is one in which the energy of reactants is greater than that of products. As such, energy is given off during the reaction in form of heat.

Thus, the true statement about an exothermic reaction is that reactants have more energy than products.
