Identify the type of reaction: 2AgCl + BaBr2 -> 2AgBr + BaCl2
A) decomposition
B) combustion
C) double replacement
D) single replacement ​

Answers

Answer 1

Answer:

C

Explanation:

Just look at the reactants.

2AgCl + BaBr2

The first reactant is made of 2 elements.

The second reactant is made of 2 elements.

It can't be a decomposition. At this level there is only one reactant made of 2 elements. Something like

2MgO ===> 2Mg + O2

is a decomposition.  One compound breaking down into 2 elements Mg and O.

It can't be a combustion. One of the reactants in a combustion is oxygen. Those equations look like

C3H8 + 5O2 ==> 3CO2 + 4H2O

That would be what a combustion looks like

It can't be a single replacement. They look like

Mg + CuO ===> Cu + MgO

There are elements on both sides of the reaction.

that leaves a double replacement which I wrote about how you distinguish it.

what properties of gold and platinum make these metals desirable for jewelry?

Answers

Answer: They are non-reactive and don't conform with other elements to form compounds. Because they are non-reactive, they don't corrode easily.

Explanation:

The  properties of gold and platinum  which make these metals desirable for jewelry is due to their electronic configuration due to which they are non-reactive and do not corrode easily.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

A mixture contains 21.7 g NaCI, 3.74 g KCI, and 9.76 g Lici. What is the mole fraction of NaCl in this mixture?

Molar mass
NaCl: 58.44g/mol
KCl: 74.55g/mol
LiCl: 42.39g/mol​

Answers

Answer:Mole Fraction of NaCl=0.5697

Explanation:

No OF Moles of NaCl=  Mass / Molar mass

=21.7 g/58.44g/mol

=0.371moles

No OF Moles of KCl=  Mass / Molar mass

=3.74g/74.55g/mol

=0.0502moles

No OF Moles of LiCl=  Mass / Molar mass

=9.76 g/42.39g/mol

=0.230moles

Mole Fraction of NaCL = Moles of NaCL/ Total number of moles of the mixture

=0.371/( 0.371+ 0.0502+0.230)

0.371/0.6512

=0.5697

Answer:

Mole fraction: 0.570

Explanation:

Mole fraction is defined as the ratio of moles of a compound in a mixture over the total moles of the mixture. To solve this problem, we need to find moles of the 3 salts:

Moles NaCl -Molar mass: 58.44g/mol-:

21.7g NaCl * (1mol / 58.44g) = 0.3713 moles

Moles KCl -Molar mass: 74.55g/mol-:

3.74g KCl * (1mol / 74.55g) = 0.0502 moles

Moles LiCl -Molar mass: 42.394g/mol-:

9.76g LiCl * (1mol / 42.394g) = 0.2302 moles

Mole fraction NaCl:

0.3713mol / (0.3713mol + 0.0502mol + 0.2302mol) =

0.570

If there are 400 radioactive atoms in a sample, how many will remain after four half-lives have passed?
Enter the exact number as your answer. Do not spell out the number.

Answers

Answer:

25 atoms

Explanation:

Given data:

Total number of atoms = 400 atom

Atoms remain after 4 half lives passed = ?

Solution:

At time zero = 400 atom

At first half life = 400 atom/2 = 200 atom

At 2nd half life = 200 atom/2 = 100 atom

At 3rd half life = 100 atom/2 = 50 atom

At 4th half life = 50 atom/2 = 25 atom

Thus, 25 atoms are remained after 4 half lives.

25 atoms of the radioactive atoms will remain after 4 half lives.

    Given in the question,

Initial amount of a radioactive element = 400 atomsNumber of half lives = 4

Expression for the amount remaining of a radioactive element after 'n' half lives is given by,

[tex]N=N_0(\frac{1}{2})^n[/tex]

Here, [tex]N_0=[/tex] Initial amount

[tex]n=[/tex] Number of half lives

By substituting the vales of [tex]N_0[/tex] and [tex]n[/tex] in the question,

[tex]N=400(\frac{1}{2})^4[/tex]

   [tex]=\frac{400}{16}[/tex]

   [tex]=25[/tex]

        Therefore, 25 atoms of the radioactive atoms will remain after 4 half lives.

Consider the reaction
H,01) +energy > H2(g) +%02(g)
Which of the following phrases best describes this reaction?
A Endothermic, absorbing energy
B) Endothermic, releasing energy
C) Exothermic, absorbing energy
D) Exothermic, releasing energy

Answers

The following phrases best describe this reaction : A Endothermic, absorbing energy

Further explanation

Delta H reaction (ΔH) is the amount of heat change between the system and its environment  

(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)  

∆H positive (endothermic): energy (heat) is absorbed from the environment to the system

∆H negative (exothermic): energy (heat) released from the system to the environment

Reaction

H₂O(g) + energy ⇒ H₂(g) + 1/2O₂(g)

In this reaction, it is shown that to break the bonds on the H₂O molecule to form H₂ and O₂ molecules will require energy (breaking the bonds requires energy)

This energy is usually called ∆H dissociation⁰

how many atoms are there in 8.08 moles of carbon dioxide

Answers

Answer:

145.97×10²³ atoms

Explanation:

Given data:

Number of moles of CO₂ = 8.08 mol

Number of atoms of CO₂ = ?

Solution:

1 mole of CO₂ contain 1 mole C atom.

8.08 mole contain 8.08× 1 = 8.08 mole of C atom.

1 mole of CO₂ contain 2 moles of O atom.

8.08mole contain 8.08×2 = 16.16 mole of O atom.

Total number of moles of atoms = 8.08 mole + 16.16 mole

Total number of moles of atoms = 24.24 mol

Number of atoms of CO₂:

1 mole of any substance contain 6.022×10²³ atoms.

24.24 mol ×6.022×10²³ atoms / 1 mol

145.97×10²³ atoms

The electron dot notation shows only the chemical symbol of the element surrounded by dots to represent the valence electrons. The chemical symbol denotes the nucleus and all electrons except the valence electrons.

The dots are arranged on the four sides in pairs.

Oxygen is made up of 6 valence electrons, and since the ion has a net negative charge, the hydrogen and oxygen achieved their stable configuration this way.

Is nuclear energy poised to be part of America’s future?

Answers

Answer:

Nuclear energy powers our businesses, homes and military. America’s 95 operating nuclear reactors generate approximately 20% of our nation’s electricity and provide over half of our carbon-free energy. They also create good-paying jobs at power plants and uranium mines. Wyoming produced 87% of America’s domestic uranium supply in 2018.

Today, nuclear energy faces serious hurdles. Regulatory costs and subsidies for renewable energy technologies are forcing America’s nuclear power plants to close at an alarming rate.

Russia and China are subsidizing their government-owned nuclear companies to assert their energy influence around the world. China is searching the globe for uranium reserves and investing heavily in the countries where it’s found. They want to secure more nuclear fuel for themselves and increase their control of the global supply.

Meanwhile, American nuclear power plants have come to rely on cheap Russian imports of uranium to meet their nuclear fuel needs. Right now, roughly 40% of the uranium coming into the United States originates in Russia or its satellite states of Kazakhstan and Uzbekistan. Russian-backed companies are developing fuel that can be placed directly in American reactors.

The cells in both bicep muscle and heart muscle make energy for contraction and relaxation. Hence, option B is correct.

What is cardiac muscles ?

Cardiomyocytes have a rather rectangular form and are short and thin. They have a single nucleus, cell organelles that are identical to those seen in skeletal muscle cells, and many sarcosomes, which supply the energy needed for contraction.

Intercalated discs with gap junctions for diffusion and communication link cardiomyocytes structurally. Myofibrils, which in turn are composed of thick and thin myofilaments, make up the sarcoplasm.

Due to their high energy needs, skeletal muscle cells have many mitochondria that enable them to produce enough ATP. Therefore, the cells in the bicep muscles and cardiac muscles produce energy.
