balancing skeleton equation can someone help me with this ​

the products are:

CaCO3 Calcium Carbonate

CO2 carbon dioxide

NaCI Sodium chloride

H2O​ Water

Answer:

Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon. ... The carbon-14 method was developed by the American physicist Willard F. Libby about 1946.

Explanation:

Answer:

Boiling water- When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion. ... ice melting - Ice melts because heat moves to the ice from the air.

Answer:

water, H20

Explanation:

From the given choices, only water has two unshared or lone pairs of electrons in its central atom.

The formula of water is:

              H₂O

H is hydrogen with 1 electron

O is oxygen with 8 electrons and 6 valence electrons

To form the covalent bond, the 6 valence electrons are involved. Two out of the 6 bonds with the two oxygen.

The remaining 4 gives the two lone pairs.

Electron is negatively charged particle. When building electric circuits electron flow along the path. so, option C is correct.

Electrons are fundamental to many physical processes, including gravity, electromagnetic interactions, weak interactions, electricity, magnetism, chemistry, and thermal conductivity.

The outer shells of atoms in the common items you encounter are made up of matter particles called electrons.

A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound). One of the three main types of particles within an atom is an electron that is bonded to it.

The other two are protons and neutrons. The nucleus of an atom is made up of electrons, protons, and neutrons together.

Thus, Option C is correct.

A radioactive decay is occurring by the emission of charged particles such alpha or beta to form a new stable atom with changes mass number and atomic number.

Heavy unstable radioactive elements undergo nuclear decay by which they form a stable isotope or new atom with changed atomic number. There are two types of nuclear decays mainly. They are alpha decay and beta decay.

During alpha decay isotopes with higher mass number undergo alpha emission and forming a new species with mass number reduced by 4 units and atomic number reduced by 2 units.

In the case of beta- decay, electrons are emitted from the atom and then forming a new atom with atomic number increased by one unit. For an electron capture process, an electron is captured to the atom forming an element with atomic number reduced by one.

Explanation:

The productivity of photosynthesis affect the productivity of cellular respiration by providing energy.

Photosynthesis is a process where plants prepare their food in the presence of sunlight.

Photosynthesis process chemically illustrated as :

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

From the above it is clear that carbohydrate is produced in the photosynthesis process and this carbohydrate provide energy to the plant for the completion of another chemical process. So, for the cellular respiration plants use this energy.

Hence, the productivity of photosynthesis directly affect the productivity of cellular respiration.

Answer:

The charge is +3

Explanation:

In Fe₂(SO₄)₃ the global charge is 0.

As we know, the sulfate ion, SO₄, has a charge of -2, as there are 3 SO₄ ions in the molecule, the global charge is -2*3 = -6. To solve for the charge of Fe we can use:

2Fe - 6 = 0

2Fe = +6

Fe = +3

Answer:

B

Explanation:

The statement false about solution has been that all solutions are mixtures. Thus, option A is correct.

The solution can be defined as the dissolution of two or more substances. Thus, all solutions are been considered as dissolution of the solute and solvent molecules.

The solution has generally been the homogenous mixture as there has been the complete dissolution of the substances. However, the mixture can be defined as the combination and not the complete dissolution of the substances.

Thus, all solutions have not been considered as mixtures. Thus, option A is correct.

Answer:

CH3O

C6H18O6

Explanation:

Porcentaje de masa de oxígeno = 100% - (33,002% + 9,063%) = 57,935%

Divida el porcentaje en masa de cada elemento por su masa atómica relativa;

H- 9.063 / 1, C- 33.002 / 12, O - 57.935 / 16

H- 9.063, C- 2.75, O- 3.62

Dividir por la proporción más baja;

H-9.063 / 2.75, C- 2.75 / 2.75, O- 3.62 / 2.75

H- 3, C-1, O- 1

Fórmula emperical = CH3O

Dado que la masa molecular es 191 g / mol

Sea n el número de cada átomo de la molécula

Por tanto, su fórmula molecular es; (CH3O) n = 191

[12 + 3 (1) + 16] n = 191

31n = 191

n = 191/31

n = 6

Por lo tanto, la fórmula molecular del compuesto es; (CH3O) 6 que es C6H18O6
