Which reaction will proceed most quickly or be the easiest?

A. Li and F
B. Li and CI
C. Nah and F
D. Na and CI

Answers

Answer:

C. Na and F

Explanation:

The reaction between Sodium and fluorine will proceed more quickly and easily of all the given reaction choices.

This is because fluorine is the most electronegative element and sodium is more electropositive when compared to Lithium.

This significantly large electronegativity difference between the atoms confers a high reactivity on both of them. In this reaction, an ionic bond forms by the virtue of sodium losing one electron to be gained by fluorine. This way both atoms becomes isoelectronic with Neon.

Silver metal can be prepared by reducing its nitrate, AgNO3 with copper according to the following equation:

Cu(s) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 Ag(s)

What is the percent yield of the reaction if 71.5 grams of Ag was obtained from 127.0 grams of AgNO3 ?

Answers

%yield = 88.5%

Further explanation

Given

Reaction

Cu(s) + 2 AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)

Required

The percent yield

Solution

mol AgNO₃(MW=169,87 g/mol) :

= mass : MW

= 127 : 169.87

= 0.748

mol Ag from equation :

= 2/2 x mol AgNO₃

= 2/2 x 0.748

= 0.748

Mass Ag (theoretical) :

= mol x Ar Ag

= 0.748 x 108

= 80.784

% yield = (actual/theoretical) x 100%

%yield = 71.5/80.784 x 100%

%yield = 88.5%

What is the molar mass of Cr2(SO4)3?
O 148.1 g
0 288.0 g
O 344.2 g
0 392.2 g
200.0 g

Answers

Answer:

392g

Explanation:

The given compound is;

         Cr₂(SO₄)₃

To find the molar mass, we sum the atomic masses of the elements in the compounds together.

Atomic mass of Cr  = 52

                           S  = 32

                            O  = 16

So;

 Molar mass  = 2(52) + 3[32 + 4(16)]  = 392g/mol

Rank the states of matter from the LEAST amount of energy to MOST

A.Liquid, Gas, Solid
B.Solid, Liquid, Gas
C.Solid, Gas, Liquid
D.Gas, Liquid, Solid

Answers

Answer:

The ranking of matter from the LEAST amount of energy to MOST amount of energy is;

B. Solid, Liquid, Gas

Explanation:

The kinetic energy of the particles that make of matter depends on the temperature of the particles and the particles are constantly vibrating

Solid state (Least amount of energy)

In the solid state, the matter is held in solid (rigid) crystal lattice and the particles are rigidly located next to other adjacent particles and stacked up layer by layer

Liquid state (Intermediate amount of energy)

As the temperature of the particles are increased by heating, the particles (atoms and molecules) gain more kinetic energy and their vibration is increased which on further heating, leads to the breaking of the lattice bond of the solid state and the particles are then readjusted to exist side by side rather than being stacked on one another and the assume the liquid state

Upon further heating the particles in the liquid acquire more energy and are  and rather than exist side-by-side, they are able to exist as individual particles in the gaseous form

Gaseous state (Most amount of energy)

From the kinetic theory of matter, the molecules of matter in the gaseous state contains enough energy which is more than the intermolecular forces of attraction such that the particles are able to move and occupy the entire volume of the container in which it is placed

Therefore, the correct option is Solid, Liquid, Gas.

Formula:

Number of moles = mass/ molar mass

Molar mass of Ne = 20.17 g/mol

Number of moles = 10090 g/ 20.17 g/mol

Number of moles = 500.25 mol

What is the frequency of light with a wavelength of 3.2 x 10^-16 m?

Answers

Answer:

f = 0.94 ×10²⁴  Hz

Explanation:

Given data:

Frequency of light = ?

Wavelength of light = 3.2 ×10⁻¹⁶ m

Solution:

Formula:

Speed of light = wavelength × frequency

c = λ × f

c = speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s  = f × 3.2 ×10⁻¹⁶ m

f  =  3×10⁸ m/s   / 3.2 ×10⁻¹⁶ m

f  = 0.94 ×10²⁴ s⁻¹

f = 0.94 ×10²⁴  Hz (Hz = s⁻¹)

Calculate the number of grams of solute in 814.2mL of 0.227 M calcium acetate

Answers

Answer:

Mass = 29.23 g

Explanation:

Given data:

Volume of solution = 814.2 mL 814.2/1000 = 0.8142 L)

Molarity of solution = 0.227 M

Mass of solute in gram = ?

Solution:

Molarity = number of moles / volume in L

By putting values,

0.227 M = number of moles / 0.8142 L

Number of moles = 0.227 M × 0.8142 L

Number of moles = 0.184 mol

Mass in gram:

Mass = number of moles × molar mass

Molar mass of calcium acetate = 158.17 g/mol

Mass = 0.184 mol × 158.17 g/mol

Mass = 29.23 g

D
29 protons, 31 electrons

Answers

Answer:

B  29 protons, 27 electrons

Explanation:

The given specie is copper ion:

         Cu²⁺  

We are to find the number of protons and electrons it contains.

 The number of protons is the positively charged particles in the atom.

 Electrons are the negatively charged particles in the atom.

The number of protons is the same as the atomic number

Atomic number of copper  = 29

 Number of protons  = 29

 Now;

    Charge  = Number of protons  - Number of electrons

     2  = 29  - number of electrons

     -27  = - number of electrons

 Number of electrons  = 27

B. They are highly reactive.
C. They are hard metals.
D. They are soft nonmetals.

Answers

Answer:

B. They are highly reactive.

Explanation:

Answer:

B: They are highly reactive

Explanation:

Sodium(Na) and potassium(K) are in the same family/group which is the Alkali Metal group.  These groups have their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water. This is because enough heat is given off during the exothermic reaction to ignite the H2(g). Therefore, they are similar because of their reactivity.

Large amounts of an unknown compound were isolated from seawater. The compound contained 32.0 grams ofbromine and 4.9 grams of magnesium. What is its percent composition?

Answers

Answer:

87% bromine and 13% magnesium

Explanation:

The compound contained 32.0 grams of bromine and 4.9 grams of magnesium.

We need to find its percent composition.

Mass of the sample = mass of bromine + mass of magnesium

= 32 g + 4.9 g

= 36.9  g

Percentage composition of bromine,

[tex]\%=\dfrac{32}{36.9}\times 100\\\\=86.7\\\\=87\%[/tex]

The percentage composition of magnesium,

[tex]\%=\dfrac{4.9}{36.9}\times 100\\\\=13.27\\\\=13\%[/tex]

So, its percent composition is 87% bromine and 13% magnesium.
