Explanation:

9g of water contains : 9g/18 g/mol = 0.5 mole of water

1) 2 moles of hydrogen yields 2 moles of water

x moles of hydrogen yields 0.5 moles of water

x= 2 × 0.5/2 = 0.5 moles of hydrogen

Mass of hydrogen = 0.5 moles × 2 = 1 g of hydrogen

2) Number of moles of Al(OH)3 = 468 g/ 78 g/mol = 6 moles

2 moles of Al(OH)3 yields 3 moles of H2O

6 moles of Al(OH)3 yields 6 × 3/2 = 9 moles of H20

Mass of water =9 moles × 18 g/mol = 162 g of water

3) There are 13 oxygen atoms in the compound.

Mass of each oxygen atom = 16 g

Total mass of oxygen atoms = 13 × 16 = 208 g

Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure , which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.

Amino group, R group, and the carboxylic acid group. Hence, option B is correct.

The molecule is described as the, A. lipid with three unsaturated fatty acids.

A collection of two or more atoms bonded together by attractive forces known as chemical bonds is referred to as a molecule. In the given question, the molecule shown in diagram is a lipid, or triglyceride, with three fatty acids and a glycerol backbone. Unsaturated fatty acids are those with double or triple bonds in their molecular makeup.

Depending on how many double or triple bonds are typically there in its structure, a fatty acid can either be polysaturated or monounsaturated. Generally, there are three unsaturated fatty acids in this lipid, all of which contain one double bond in their structures.

Answer:

0.3 sec : -0.4 m

0.5 sec: -1.2 m

0.7 sec: -2.3 m

Explanation:

0.3 sec: 1/2(-9.3 m/s^2)(0.3 s)^2 = -0.4 m

0.5 sec: 1/2(-9.3 m/s^2)(0.5 s)^2 = -1.2 m

0.7 sec: 1/2(-9.3 m/s^2)(0.7 s)^2 = -2.3 m

Carbon has an atomic number of 6 so its electron configuration will be 1s² 2s² 2p². It has two orbitals as indicated with the 2 as its period number with the outer orbital have 4 valence electrons. So carbon is in the p-orbital, period 2 and in group 4.

Answer:

For 1: Ionic

For 2: Ions

For 3: Covalent

For 4: Single

For 5: Double

For 6: Polar

Explanation:

An ionic compound is formed when the complete transfer of electrons takes place from one element usually, metals (forming cation) to another element usually, non-metals (forming anions).

Hence, an ionic bond forms when one atom gives up one or more electrons to another atom

An ion is formed when an element loses or gains an electron. Two types of ions are formed which are cations and anions.

Hence, atoms or molecules with a net electric charge due to the loss or gain of one or more electrons are ions.

A covalent bond is defined as the bond which is formed by the sharing of electrons between two atoms.

Hence, a covalent bond involves sharing electron pairs between atoms, also known as a molecular bond.

A single bond is defined as the bond in which 1 bond is present between the two atoms or 1 pair of electrons (two electrons) are shared between the atoms.

Hence, when one pair of electrons is shared between two atoms, a single bond is formed.

A double bond is defined as the bond in which 2 bonds are present between the two atoms or 2 pairs of electrons (four electrons) are shared between the atoms.

Hence, when two pairs of electrons are shared between two atoms, a double bond is formed

A polar bond is defined as the bond where unequal sharing of electrons takes place. This creates a dipole within a molecule.

Hence, a polar bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms.

"How to prevent the collapse of the dam that contains water from heavy rains?"

Explanation:

Scientists must work to create innovations capable of bringing benefits to human life and combating disadvantageous and harmful situations. The overflow of dams is something very harmful, as the resulting flooding can cause structural, economic and even public health problems. When this overflow is caused by natural elements, such as heavy rains, the work of scientists in solving these issues is even more important and necessary. In order to resolve the dam failure caused by excess rainwater, scientists must work to answer the following question:

"How to prevent the collapse of the dam that contains water from heavy rains?"

Answer:

Explanation:

By the kinetic molecular theory (particle model), all matter consists of particles, there are spaces between the particles, the particles are in constant random motion, and there are forces of attraction and repulsion between the particles.

Furthermore, temperature is defined to be a measure of the average kinetic energy of the particles.

Evaporation is a change of phase from liquid to gas explained as follows :

When particles in the liquid phase are heated, they gain kinetic energy and move faster and further apart. Eventually they have enough energy to escape the forces of attraction holding them together in the liquid phase and they move very fast and far from each other and exist in the gaseous phase.

I'd go with Option C.

Sodium Hydroxide.

There are seven oxygen atoms, so the total charge is −2⋅7=−14 . So, two chromium atoms have a total oxidation number of +12 . Since one is not more electronegative than the other, we can divide the number by two to get one chromium's oxidation number. So, a chromium atom here has an oxidation number of +6 .

19. 288,057.12

20. 0.74497354

Respuesta:

199.5 g

Explicación:

Paso 1: Escribir la reacción balanceada

2 Al + 3 H₂SO₄ ⇒ Al₂(SO₄)₃ + 3 H₂

Paso 2: Calcular la masa pura de 50 g  de Al

Aluminio tiene 10% de impurezas, es decir, 10% de 50 g = 5 g. Luego, tiene 50 g - 5 g = 45 g de Al puro.

Paso 3: Calcular la masa teórica de Al₂(SO₄)₃ obtenida a partir de 45 g de Al

La relación de masas de Al₂(SO₄)₃ a Al es 342:54.

45 g Al × 342 g Al₂(SO₄)₃/54 g Al = 285 g Al₂(SO₄)₃

Paso 4: Calcular la masa real de Al₂(SO₄)₃ obtenida

El rendimiento de la reacción es de 70%.

285 g × 70% = 199.5 g

The correct answer is LiOH and Li2SO4.

A strong acid is neutralized by a strong base to yield a normal salt.

A neutralization reaction is a reaction between an acid and a base to yield salt and water only.

An acid can be strong or weak. A base can also be strong or weak.  "Strong" or "weak" has to do with the extent of ionization of the acid or base in water. Usually, a strong acid is neutralized by a strong base.

Since H2SO4 is a strong acid, it will require a strong base such as LiOH to neutralize it and the product will be the normal salt Li2SO4.
