Give the systematic name for the following coordination compound or complex ion:

Answer:

0.42 moles Na₂O

Explanation:

Molarity: 1.2 M

Volume (mL): 350 mL

Volume (L): 0.35 L

350 mL / 1,000 mL = 0.35 L Na₂O

Molarity (M) =  moles / liters (L)

1.2 M Na₂O = ? moles / 0.35 L Na₂O

(1.2 M Na₂O) x (0.35 L Na₂O) = ? moles

? = 0.42 moles Na₂O

The second law of thermodynamics states, in part, that "every spontaneous activity in any isolated system always leads in a rise in the entropy of that system." Because the universe is an isolated system, this assertion may be represented mathematically as follows: (1.6-2)

Explanation:

i took the quiz.

The required volume of sample of neon occupy at these conditions of temperature and pressure is 25.2L.

Mass (W) in grams of helium gas will be converted into moles (n) by using the below equation:

n = W/M, where

M = molar mass = 4g/mol

n = 12g / 4g/mol = 3 mol

n = 24g / 4g/mol = 6 mol

And for this question as pressure and temperature for both the conditions is constant so ideal gas equation becomes:

V₁/n₁ = V₂/n₂, where

V₁ = initial volume = 12.6 L

n₁ = initial moles = 3 mol

V₂ = final volume = ?

n₂ = final moles = 6 mol

On putting these values, we get

V₂ = (12.6)(6) / (3) = 25.2 L

Hence required volume of neon gas is 25.2 L.

Answer:

1.38 M

Explanation:

Need to use the Molarity equation M=n/L

23.5g/ 17.031g/mol NH3 = 1.38 moles

1.38 moles/ 1.0 L = 1.38 M

Answer:

Across a row, atomic radii decreases.

Explanation:

It decreases because nuclear charge increases across a row, electrons are added to the same shell and shielding remains constant. Therefore the outer electrons are more attracted to the nucleus making the atom smaller.

The mass percentage of water (H₂O) in cadmium chloride tetra hydratesolution is equal to the 28.2%.

Mass percentage of any substabce present in any solution will be calculated as:
Mass percent = (Mass of substance/Total mass of solution)×100%

According to the question,

Mass of water (H₂O) = 18.02 g/mol

Mass of solvent (CdCl₂.4H₂O) = 183.32 + 4(18.02) = 255.4 g/mol

On putting values, we get

Mass percent = (18.02 / 255.4) × 100% = 28.2%

Hence mass percent of water is 28.2%.

Answer:

12.82 liters

Explanation:

From periodic chart ...mole weight of neon = 20.1797 gm/mole

23 g / 20.1797 g/mole = 1.14 moles

PV = n R T          R = gas constant = .082057 L-Atm / K-mole

                            n = 1.14

                             T = 1 C = 274.15 K

2 * V = 1.14 * .082057 * 274.15     Solve for V = 12.82 liters

Answer:

Explanation:

Count the number of species that are bonded to chromium in this complex ion. There are four ammonia molecules and two chlorine atoms bonded to chromium. This yields a coordination number of 6.

The co-ordination number of chromium ion in complex [Cr(NH₃)₄Cl₂][tex]^+[/tex] is six as there are four ammonia molecules and 2 chlorine molecules bonded to chromium which gives total co-ordination number of 6.

An ion is defined as an atom or a molecule which has a net electrical charge. There are 2 types of ions :1) cation 2) anion . The cation is the positively charged ion and anion is the negatively charged ion . As they are oppositely charged they attract each resulting in the formation of ionic bond.

Ions consisting of single atom are mono-atomic ions while which consists of two or more ions are called as poly-atomic ions . They are created by chemical interactions . They are very reactive in their gaseous state and rapidly react with oppositely charged ions resulting in neutral molecules.

Explanation:

Fission is the formation of two smaller atoms by the collision of the neutrons. The quantity of energy produced per gram is 7.23 × 10¹⁰ J/g.

Nuclear fission is a process in which the neutron collides with the atom and results in the formation of two isotopes.

The nuclear fission reaction is shown as,

[tex]\rm ^{235}_{92}U + ^{1}_{0} n \rightarrow ^{144}_{54} Xe + ^{90}_{38}Sr + 2^{1}_{0}n[/tex]

Energy in joules is calculated by the Einstein's formula as:

[tex]\begin{aligned} \rm E &= \rm mc^{2}\\\\&= 3.139 \times 10^{-28} \times (2.99 \times 10^{8})^{2}\\\\&= 2.82 \times 10^{-11}\;\rm J\end{aligned}[/tex]

Energy per gram is calculated as:

[tex]\begin{aligned}& =\dfrac{ (2.82 \times 10^{-11})(6.022 \times 10^{26})}{235.043}\\\\&= 0.0722 \times 10^{12}\\\\&= 7.23 \times 10^{10} \;\rm J/g\end{aligned}[/tex]

The largest mass silver chloride is precipitated when excess silver ions are added to 30.0cm3 of 0.30M iron(III) chloride solution.

A precipitation reaction is a reaction in which an insoluble substance is obtained when two solutions are mixed together as a result of one of the products of the reaction being insoluble in water.

Silver chloride is an insoluble salt that will precipitate when a single silver salt is added to a soluble chloride salt.

In the above, the largest mass silver chloride is precipitated when excess silver ions are added to 30.0cm3 of 0.30M iron(III) chloride solution since iron (iii) chloride is a weak electrolyte.
