why is it important to know the number of valence electrons in an atom?

Answers

Answer:

Valence electrons are the electrons in the outermost energy level of an atom — in the energy level that is farthest away from the nucleus. Being able to determine the number of valence electrons in a particular atom gives you a big clue as to how that atom will react.

Explanation:

Magnesium bromide is an ionic compound with the chemical form MgBr2 what does the 2 tell you

Answers

Answer:

The number of Bromine combining magnesium

Explanation:

The subscript gives the number of atom/s combining to form a compound. For this problem, 1 atom of Mg combines with 2 atoms of Br.

To form the ionic combine, Mg will lose two electrons. A bromine atom requires just one electron to have a complete octet. So, two bromine atoms will be needed to complete the bonding process.

Therefore, Mg loses two electrons to two Br atoms and the electrostatic attraction from the charges created forms the ionic bond.

The number 2 represents the number of bromine atoms.

An ionic compound is formed when the complete transfer of electrons takes place from one element (usually metals) to another element (usually non-metals).The element losing electron (metal) forms a positive ion known as a cation while the element gaining electron (non-metal) forms a negative ion known as an anion.

Magnesium bromide is formed by the combination of magnesium (metal) and bromine (non-metal).

The valency of magnesium is 2 while that of bromine is 1. To form a neutral compound 2 moles of bromine ion combines with 1 mole of magesium ion.

Thus, the number 2 represents the number of bromine atoms.

Copper(I) complexes tend to be tetrahedral rather than octahedral or square planar. Why is this the case? Explain your reasoning.

Answers

Answer:

The ion is d^10

Explanation:

Tetrahedral geometry is one in which the central atom/ion is located at the center of four ligands positioned at the corners of a tetrahedron.

It is different from a square planar complex wherein the ligands are positioned at the corners of a square with the central atom/ion at the center of the square.

Tetrahedral complexes are more common with d^10 species.The electronic configuration of Cu I is [Ar]3d104s1. Hence, a tetrahedral geometry is preferred over a square planar geometry.

A solution contains 9.25x103 M copper(II) nitrate and 1.40x102 M manganese(II) acetate. Solid potassium carbonate is added slowly to this mixture.
A. What is the formula of the substance that precipitates first?
B. What is the concentration of carbonate ion when this precipitation first begins?

Answers

Answer:

Explanation:

Concentration of Cu⁺² = 9.25 x 10³ M

Concentration of Mn⁺² = 1.4 x 10² M

solubility product of copper carbonate = 7.08 x 10⁻⁹

solubility product of manganese  carbonate = 2.24 x 10⁻¹¹

solubility product of later is less so carbonate of manganese will come out first .

B )

[ Mn⁺² ] [ CO₃⁻² ] = 2.24 x 10⁻¹¹

1.4 x 10²  [ CO₃⁻² ] = 2.24 x 10⁻¹¹

[ CO₃⁻² ] = 1.6 x 10⁻¹³ .

the concentration of carbonate ion when this precipitation first begins

= 1.6 x 10⁻¹³ M .

Mass percentage does not have any unit as numerator and denominator contains the same unit. The percent by mass of Ca in CaCl[tex]_2[/tex] is equal to (40/111) x 100. The correct option is option A.

What is percentage by mass?

Mass percentage represents the the percentage of each element that is making a particular compound.

Mathematically,

Percentage of mass = (component’s mass ÷ total mass) x 100%

Atomic weight of different element of calcium chloride{ CaCl[tex]_2[/tex]} are

Ca = 40 ; Cl = 35

Total mass of Calcium element in calcium chloride = 40g/mol

Total mass of Chlorine atom in calcium chloride = 35× 2= 71g/mol

Total molar mass of calcium phosphate = 40 +71= 111g/mole

Percentage of calcium in calcium chloride =40÷111 = 36%

Therefore, the percent by mass of Ca in CaCl2 is equal to (40/111) x 100. The correct option is option A.

Reactants → Products

Chemical reactions are characterized by the formation of new products, and the making and breaking off strong chemical bonds.

Answer: They are the PRODUCTS of the reaction.

Explanation: In a chemical reaction, there are the REACTANTS and the PRODUCTS.

The reactants are the "ingredients" in the chemical formula. They are what are being chemically combined in a way.

The products are the "meal," or what the reactants combined to create.

For example, when creating salt or NaCl, this is essentially the formula:

Na + Cl = NaCl

In this formula, Na (sodium) and Cl (chlorine) are the reactants. NaCl (sodium chloride, aka salt) is the product.

Which equation best represents the balanced net ionic equation for the reaction that occurs when aqueous solutions of lithium phosphate and magnesium nitrate are mixed?

Answers

Answer:

2 PO₄³⁻(aq) + 3 Mg²⁺(aq) ⇒ Mg₃(PO₄)₂(s)

Explanation:

Let's consider the molecular equation that occurs when aqueous solutions of lithium phosphate and magnesium nitrate are mixed.

2 Li₃PO₄(aq) + 3 Mg(NO₃)₂(aq) ⇒ 6 LiNO₃(aq) + Mg₃(PO₄)₂(s)

The complete ionic equation includes all the ions and insoluble species.

6 Li⁺(aq) + 2 PO₄³⁻(aq) + 3 Mg²⁺(aq) + 6 NO₃⁻(aq) ⇒ 6 Li⁺(aq) + 6 NO₃⁻(aq) + Mg₃(PO₄)₂(s)

The net ionic equation includes only the ions that participate in the reaction and insoluble species.

How many mL of O2 at STP are produced from 1.5 g KClO3

Answers

Answer:

64.2 L

i watch videos about this stuff because my grades were very low now im bringing the up

Explanation:

In order to be able to calculate the volume of oxygen gas produced by this reaction, you need to know the conditions for pressure and temperature.

Since no mention of those conditions was made, I'll assume that the reaction takes place at STP, Standard Temperature and Pressure.

STP conditions are defined as a pressure of

100 kPa

and a temperature of 0∘C

. Under these conditions for pressure and temperature, one mole of any ideal gas occupies

22.7 L

- this is known as the molar volume of a gas at STP.

So, in order to find the volume of oxygen gas at STP, you need to know how many moles of oxygen are produced by this reaction.

The balanced chemical equation for this decomposition reaction looks like this
