How Many Valence Electrons Does The Following Isotope Have?
Answer 2

Nitrogen is 7th element in periodic table. It contains 7 electrons in which are 2 are inner electrons and 5 are outer electrons. Here N is in -3 oxidation state. Thus, it is having 8 valence electrons.

What is an isotopes?

Isotopes of are atoms with same atomic number and different mass numbers. Almost every elements have isotopes but some of them are unstable in nature.

Atoms forms ions when they lose or gain electrons. Wen they lose electrons, they form positive ions called cations. When they gain electrons they form negative ions or anions.

Nitrogen is 7th element in periodic table. It has 7 electrons out which 2 are inner electrons and 5 are valence electrons. N needs 3 more electrons to attain octet. Thus it gains 3 electrons and forms its 3 - oxidation state.

Thus N in -3 oxidation state have 8 valence electrons.

Equation for the incomplete combustion of methanol

Answers

Answer:

The basis for incomplete combustion is that instead of carbon dioxide being produced alongside water, carbon monoxide and carbon is produced instead, the carbon being released as soot. That handily sets the products up for the equation.

And combustion is simply a reaction between a fuel, in this case, methanol and oxygen.

The chemical formula for methanol is CH3OH. Simply write the reactants and products as a chemical equation and balance it, and you have the equation.

How many grams of NaOH is needed to neutralize 90 mL of 1.5 N HCl?

Answers

mol = conc × v

= 1.5 × 0.09

= 0.135 moles of HCl

HCl + NaOH > NaCl + H2O

1 mole HCl = 1 mole NaOH

0.135 mol HCl = x

x = 0.135 mol NaOH

mass = mol × molar mass

= 0.135 × 40

= 5.4 g

NaOH = 23 + 16 + 1 = 40 g/mol

The effect of a catalyst is

Option B(lower the activation energy of a reaction whereby making it easier for the reactants to get over the energy hump)What is a catalyst

A catalyst allows an alternative reaction pathway that leaves activation energy than the uncatalysed reaction. This does not change the frequency of collision.

Frequency of collision

Frequency of collision depend upon concentration of reactant temperatures

Catalyst on activation energy

Hence, catalyst lowers the activation energy of reaction thereby making it easier for the reactant to get over the energy hump.

Select True or False: Consider the reaction N2(g) 3H2(g) 2NH3(g). The production of ammonia is an exothermic reaction. When heat is added to the equilibrium system it will shift to increase the amount of ammonia produced.

Answers

Answer:

False

Explanation:

As I like to think of it, equilibrium will shift either 'forwards' (to increase products) or 'backwards' (to increase reactants) to oppose any change in system;

If heat is added, the equilibrium will shift in the direction that reduces heat within the system;

In other words, it will shift in favour of the endothermic reaction, i.e. the reaction where heat is gained by the molecules/atoms and therefore taken out from the system;

If the 'forwards' reaction, producing NH₃, is exothermic (i.e. energy is released in the reaction), then the 'backwards' reaction is endothermic;

So the equilibrium will shift in this direction, which is the reaction of 2 NH₃ molecules producing N₂ and 3 H₂

what is the molecular geometry of AsCl3?

Answers

what is the molecular geometry of AsCl3?
Answer: The arsenic atom is surrounded by 4 regions of electron density, which means that its has a steric number equal to 4. According to VSEPR Theory, the molecular geometry will be trigonal pyramidal, AX3E1.

Picture:

Molecules' general shape, as well as bond lengths, bond angles, torsional angles, and any other geometrical factors that affect each atom's position, are revealed by their molecular geometry. The molecular geometry of AsCl₃ is trigonal pyramidal.

Molecule geometry is the study of the three-dimensional configuration of the atoms that make up a molecule. Because the shared pairs of electrons remain localized in a specific location between the nuclei of the involved atoms, covalent molecules have directed bonds.

Covalent compounds are generally not very hard because they are formed by two or more nonmetallic atoms.

COVALENT COMPOUNDS:

Covalent compounds are compounds whose constituent elements are joined together by covalent bonds.

Covalent bonding occurs when two or more nonmetallic atoms of an element share valence electrons. This means that covalent compounds will not be physically hard since they constitute non-metals.

Answers

Carbohydrates which include sugars and starches are the primary energy sources produced in plants and used by heterotrophic organisms.

Carbohydrates are composed of a basic chemical formula that typically contains a ratio of one Carbon atom for every two Hydrogen atoms and one Oxygen atom C1H2O1. Basically one carbon atom for every one water molecule Carbon + Water = Carbohydrate.

Monosaccharides or Single Carbon Chain Sugars include Glucose C6H12O6

Disaccharides or Double Carbon Chain Sugars include Sucrose C12H22O11

Combining monosaccharides and disaccharides create Polysaccharides which are complex sugars called starches.
