Answer:

Hydrogen chloride - diluted solution. Sulfur dioxide ( SO 2) reacts with chlorine gas (Cl 2) in the presence of moisture to give HCl and H 2 SO 4. ... H 2 SO 4 and HCl are strong acids in aqueous solutions. If more HCl is added to the solution, then carbon dioxide gas, sodium chloride and water are produced.

Explanation:

The law of conservation of mass says no atoms can be created or destroyed just rearranged so the mass at the beginning before the reaction would stay the same after it

Considering the Law of Conservation of Matter, the correct answer is the third option: the total mass of the products will be the same and has a value of 58.44 amu.

The Law of Conservation of Matter is also called the law of conservation of mass or the Law of Lomonósov-Lavoisier. This law postulates that "the mass is not created or destroyed, only transformed."

This means that the reagents interact with each other and form new products with physical and chemical properties different from those of the reagents because the atoms of the substances are ordered differently. But the amount of matter or mass before and after a transformation (chemical reaction) is always the same, that is, the quantities of the masses involved in a given reaction must be constant at all times, not changing in their proportions when the reaction ends.

In other words, then the mass before the chemical reaction is equal to the mass after the reaction.

So, in this case, if the total mass of the reactants is 58.44 amu, the total mass of the products will be the same and has a value of 58.44 amu.

Finally, the correct answer is the third option: the total mass of the products will be the same and has a value of 58.44 amu.

Explanation:

In general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.

Explanation:

Heavier particles will move more slowly and so will have a slower rate of diffusion. Smaller particles on the other hand will diffuse faster because they can move faster.

Explanation:

Answer:

The shape of a covalent molecule can be predicted using the Valence Shell Electron Pair Repulsion (VSEPR) theory. Very simply, VSEPR theory says that the valence electron pairs in a molecule will arrange themselves around the central atom (s) of the molecule so that the repulsion between their negative charges is as small as possible.

Explanation:

There are two types of chemical compound one is covalent compound and another is ionic compound in chemistry. In ionic bonds, electrons are completely transferred. Electron-pair repulsion play an important role in determining the molecular shape using VSEPR theory.

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

The shape of a covalent molecule can be predicted using the Valence Shell Electron Pair Repulsion (VSEPR) theory.  VSEPR theory says that the valence electron pairs in a molecule will arrange themselves around the central atom (s) of the molecule so that the repulsion between their negative charges is as small as possible.

Answer: An atom containing 7 protons, 8 neutrons, and 7 electrons is charge-neutral.

Explanation:

An atom is composed of protons (positively charged), neutrons (no charge) and electrons (negatively charged). The excess or defect of electrons in relation to protons determines the charge of an atom.

The atom described is an anion with -1 charge as it has one extra electron than protons.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answer:

Sulfur trioxide: SO3.

Explanation:

How I came to this conclusion:

I noticed that the compound consists of non-metals, therefore it must be a covalent compound -

meaning I use prefixes for compounds.

Sulfur is S. Simple enough. Trioxide has the prefix of tri, meaning "3". Therefore there is 3 atoms of oxygen. Combine them and I get SO3.

Don't be confused with sulfite: (SO3)2− and sulfate: (SO4)2−

Polystyrene and acetone are not soluble in water because they are non-polar substances.

A polar substance is a substance that has opposite charges on two ends of the molecule. In polar molecules, a dipole moment exists in the molecule and accounts for its interaction with water.

Water is a polar solvent. It can only dissolve polar molecules. Since polystyrene and acetone are both non-polar substances, polystyrene dissolves in acetone and not in water.

This agrees with the principle in chemistry that like dissolves like.

A coordinate covalent bond, also known as a dative bond, dipolar bond, or coordinate bond is a kind of two-center, two-electron covalent bond in which the two electrons derive from the same atom. The bonding of metal ions to ligands involves this kind of interaction. This type of interaction is central to Lewis theory.
