Write the complete nuclear equations for alpha absorption

Answers

Answer 1

Answer:

⁶¹₂₉Cu + ⁴₂He --->⁶⁵₃₁Ga

Explanation:

Nuclear reactions are reactions which occur with changes in the nucleus of an atom. Nuclear reactions usually occur with the release of large amounts of energy and radiation. Radiactive elements are elements that are involved in nuclearbreactions due to the unstable nature of their nucleus. They disintegrate spontaneously with the emission of radiations. The major types of radiations released during nuclear reactions are;

1, Alpha particles - these are positively charged radiations with strong ionizing power. Each alpha particle is a helium nucleus

2. Beta particles - these are very fast moving stream of electrons. They are negatively charged particles .

3. Gamma radiation - is a form of electromagnetic radiation.

In the alpha absorption of Cu-61, the proton number of the atom increases by 2 while the mass number increases by 4 and the Cu-61 atom is changed to Ga-65 atom. The nuclear equation is given as follows:

⁶¹₂₉Cu + ⁴₂He --->⁶⁵₃₁Ga

Calculate the pOH of a 7.68x10-7 M HCl solution.


pOH = (round to 3 sig figs)

Answers

Answer:

pOH = 7.89

Explanation:

As HCl is a strong acid, [H⁺] is equal to the original acid concentration. In other words:

[H⁺] = 7.68x10⁻⁷ M

Knowing [H⁺], we calculate the pH of the solution:

pH = -log[H⁺]pH = 6.11

With the pH, we can calculate the pOH of the solution, using the following formula:

pOH = 14 - pHpOH = 7.89

How many atoms are in 1.00 moles of Calcium (Ca)?

Answers

Answer:

One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore number of atoms in 1.00 moles of Calcium (Ca) are 6.022×10²³ atoms.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. Mole is inversely proportional to molar mass.

Mathematically,

mole =given mass ÷ molar mass

Number of atoms = moles ×6.022×10²³ atoms

Substituting the values in above formula we get

Number of atoms = 1 ×6.022×10²³ atoms

Number of atoms 1 mole of calcium = 6.022×10²³ atoms

Therefore, number of atoms in 1.00 moles of Calcium (Ca) are 6.022×10²³ atoms.

Does wasting water also waste energy? Explain your reasoning.

Answers

Answer:

Yes.

Explanation:

Wasting household water does not ultimately remove that water from the global water cycle, but it does remove it from the portion of the water cycle that is readily accessible and usable by humans. Also, "wasting" water wastes the energy and resources that were used to process and deliver the water.

Answer:

I feel like there should be more parts to this question but I think it depends on how you got your water. If you waste water after you got it from a local stream yourself, you wasted your body energy but no real electricity of any kind. If the water is processed and filtered and you end up wasting it, I guess it counts as energy being wasted too? Because the sole purpose was to bring you clean water but you didn't utilize it

A neutralization reaction occurs between sodium hydroxide and sulfurous acid. Complete the equation below for the neutralization reaction that ocurs during the titration

Answers

Answer:

2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃

Explanation:

When a base as sodium hydroxide (NaOH) reacts with an acid as sulfurous acid (H₂SO₃), the H⁺ of the acid will produce with the OH⁻ of the base H₂O. Te complementary ions will produce the respective salt (Na₂SO₃):

NaOH + H₂SO₃ → H₂O + Na₂SO₃

To balance the sodiums:

2NaOH + H₂SO₃ → H₂O + Na₂SO₃

And the hydrogens:

2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃

Answer: In balancing any chemical equations, the number of atoms of each elements on the reactant side is equals to the number of atoms of the elements on the product side.

Explanation:

Balanced Chemical equations are those equations that has the equal number of atoms of elements on both the reactants and the product sides. To ensure that the chemical equations are correctly balanced the following steps should be observed.

--> identify the elements on the reactant side and on the product side

--> identify the number of atoms of each elements.

--> multiply the number of atoms with the number that will give you a coefficient that will make both the reactant and product sides equal.

--> place the new numbers infront of the elements or compounds.

--> A final check is done to know if the equation is balanced.

From the above steps, the balanced equation of the above questions are listed below:

1.) AlBr3 + 3K ---> 3KBr + Al

2.) FeO + PdF2 --> FeF2 + PdO

3.) P4 + 6Br2 --> 4PBr3

4.) 2LiCl + Br2 --> 2LiBr + Cl2

5.) PbBr2 + 2HCl --> 2HBr + PbCl2

6.) 2CoBr3 + 3CaSO4 --> 3CaBr2 + Co2(SO4)3

7.) 2Na3P + 3CaF2 --> 6NaF + Ca3P2

8.) 2Mn + 6HI --> 3H2 + 2MnI3

9.) Li3PO4 + 3NaBr --> Na3PO4 + 3LiBr

10.) CaF2 + Li2SO4 --> CaSO4 + 2LiF

11.) 2HBr + Mg(OH)2 --> MgBr2 + 2H2O

12.) 2LiNO3 + CaBr2 --> Ca(NO3)2 + 2LiBr

13.) AgNO3 + Li --> LiNO3 +Ag

14.) Si(OH)4 + 4NaBr --> SiBr4 + 4NaOH

15.) 2NaCN + CuCO3 --> Na2CO3 + Cu(CN)2

16.) 2NH3 + H2SO4 --> (NH4)2SO4

What is a Chemical reaction?

Chemical reaction refers to reaction that take place between reacting substances in which the chemical substances are transformed to products.

When the concentration of the reactants increases, more molecules tend to interact with each other in order to form new compounds, and the rate of reaction increases. When the concentration of the reactants reduces, there are little of that molecule present, and the rate of reaction decreases

The speed of sound in air is four times as its speed in steel true or false?​

Answers

Answer:

.....false

Explanation:

the particles in the air are packed apart whereas the particles in steel are closely packed and sound travel faster in solids than in gasses..

Answer:

False

Explanation:

The speed of sound is quickest in mediums that have their molecules close apart.  The speed of sounds is quickest in solids, followed by liquids, and slowest in gasses.  The close the molecules are together, the quicker sound travels.  The sound would travel faster in the steel than in the air.

This is due to the fact that sound waves are compression waves.  This means that they rely on the way molecules collide with one another and act sort of like a spring.  

Fun fact: In the old days, people used to put their ears to the train tracks to see if a train is coming.  Sound moves so fast in metal that they can sense the vibrations miles before the train arrived.
