Sulfuric acid reacts violently with alcohol and water to release heat. It reacts with most metals, particularly when diluted with water, to form flammable hydrogen gas, which may create an explosion hazard. ... Hazardous decomposition products are as follows: sulfur dioxide, sulfur trioxide, and sulfuric acid fumes.

it acts violently with water or alcohol to release some heat, it does react to most metals, mostly when diluted with water to form flammable hydrogen gases, which may create an explosion hazard.

Explanation:

It is known that an electron pair represents a domain. Hybridization of BF_{3}BF3 will be calculated as follows.

       Hybridization = \frac{1}{2}[\text{Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge}]21[Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge]

Valence electrons of boron are 3 and no. of bonded atoms in a BF_{3}BF3 molecule is 3.

Therefore, calculate hybridization of BF_{3}BF3 as follows.

          Hybridization = \frac{1}{2}[\text{Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge}]21[Valence electrons of central atom + no. of bonded atoms + negative charge - positive charge]

                              = \frac{1}{2}[3 + 3 + 0]21[3+3+0]

                               = 3

Hence, hybridization of BF_{3}BF3 is sp^{2}sp2 , that is, trigonal planar.

Thus, we can conclude that the given image represents that it is a trigonal planar molecule with three domains.        

Answer:

electron pair => 1 covalent bond => same as H:H

Explanation:

The bar notation is generally accepted as a pair of electrons depicting a 'single' chemical bond. If two bars are shown (e.g; C=C) then two chemical bonds are represented. If three bars are shown (e.g; N≡N) then three chemical bonds are represented. This is the highest number of bonds that can exist between two elements. Hope this helps. :-)

Answer:

more than one kind of atom. a solution of atoms and molecules.​

Explanation:

a compound always contains more than one type of atom.

Although the formula for sodium chloride is NaCl, the compound does not contain actual NaCl molecules. Rather, it contains equal numbers of sodium ions with a charge of positive one (Na+) and chloride ions with a charge of negative one (Cl−).

Into the adaptive Trait!

Explanation:

Answer:

Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,

Explanation:

so it becomes negatively charged.

Negative ions (or anions) are atoms that have gained electrons.

Electrons have a negative charge so if an atom is getting more of them, it's becoming more negative.

Explanation:

In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.

El fragmento es un ejemplo de metáfora porque presenta la relación entre la idea de los ojos de Platero con el clima soleado y lluvioso.

Metáfora es un término de origen griego que se refiere a la acción de traslación. En el lenguaje, una metáfora es una figura retórica que consiste en la asignación de un concepto o expresión a una idea sin que esta se relaciones directamente con esta definición.

De acuerdo a lo anterior, en el fragmento se presenta una metáfora en la que se relacionan los ojos de Platero con las horas de sol y lluvia.

Explanation:

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

Answer:

lll and ll

Explanation:

Explanation:

atomic no. is 42

chemical symbol is Mo

no. of protons is 42

atomic mass is 95.95

no. of electrons is 42

no. of electron in outer most shell is 1

no of electrons in the n 3 shell is 18

no. of neutron is 96

The element molybdenum is 42nd element in periodic table with the symbol Mo and  a mass of 96. It have 42 electrons and 42 protons.

Molybdenum (Mo) is a transition metal in periodic table included in the d-block. The atomic number of molybdenum is 42 which is the number of protons and electrons in it.

The atomic number of a neutral atom is equal to the number of electrons in it. For a neutral atom the number of electrons and protons are equal and thus the number of both electrons and protons in Mo is 42.

Mass number is the sum of number protons and neutrons in an atom. The mass number of Mo is 96 and number of protons is 42. Thus, the number of neutrons is 96 -42 = 54.

The outer shells of Mo are 4d and 5s containing 4 and 2 electrons respectively. Thus the number of outer electrons is 6.The level n= 3 is M shell which contains 18 electrons for Mo.
