4. Daughter nuclide

5. Fusion

6. Strong nuclear force

Explanation:

4. When an atom of an element decays to a new element, the new element is called the

In a radioactive decay in nuclear physics, the product of the decay which is usually smaller (loss in mass) than its source and may or may not be radioactive is the daughter nuclide. Its source is the parent nuclide

5. Nuclear fusion is the nuclear process that involves the combination of two or more (light) atoms to produce subatomic particles and one or more atomic nucleus accompanied by an emission or absorption of energy due to the difference between the weight of the reactants and the weight of the products

The given reaction, is presented as follows;

³₂He + ¹₁H → ⁴₂He + ⁰₁e

Therefore, given that two atoms, (³₂He and ¹₁H) combine to form one atom (⁴₂He) and a subatomic electron particle (⁰₁e), the reaction is a fusion reaction

6. What keeps a nucleus together

The nucleus is made of neutrons and protons. There is an attractive nuclear force between protons and neutrons and a repulsive electromagnetic force between two or more protons. However, due to the proximity of the of the neutrons and the protons, which are together known as the nucleons, the attractive nuclear force is stronger than the electromagnetic force pushing the protons away from each other and the nucleus is kept together

Therefore, the strong nuclear force keeps the nucleus together.

Answer:

2.24 M

Explanation:

Molality is a measure of molar concentration of a solution and it can be calculated using the formula;

Molality = mole of solute ÷ kg of solvent

To calculate the number of moles present in the solute, we use the formula;

mole = mass ÷ molar mass

Molar mass of Fe(ClO2)3 = 56 + {35.5 + 16(2)}3

= 56 + (35.5 + 32)3

= 56 + (67.5)3

= 56 + 202.5

= 258.5g/mol

mole = 435/258.5

mole of Fe(ClO2)3 = 1.68mol

750g of solvent = 750/1000 = 0.750kg of solvent

Molality of the solution is thus: 1.68/0.750

Molality = 2.24 M.

Answer:

1.3 atm

Explanation:

Apply the ideal gas law: PV = nRT

Since we need to find the pressure, solve for pressure:

P = nRT / V

Plug in our given values of n = 4.6 moles, R = 0.08206 (ideal gas law constant using atm), T = 325 K, and V = 96.8 L:

P = 4.6(0.08206)(325) / 96.8 = 1.267 atm -> 1.3 atm (two significant figures)

Answer:

Carbon is an element that's found all over the world and in every living thing. Oxygen is another element that's in the air we breathe. When carbon and oxygen bond together, they form a colorless, odorless gas called carbon dioxide, which is a heat-trapping greenhouse gas. Whenever we burn fossil fuels such as coal, oil, and natural gas—whether it's to drive our cars, use electricity, or make products—we are producing carbon dioxide.

The atmosphere isn't the only part of the Earth that has carbon. The oceans store large amounts of carbon, and so do plants, soil, and deposits of coal, oil, and natural gas deep underground. Carbon naturally moves from one part of the Earth to another through the carbon cycle. But right now, by burning fossil fuels, people are adding carbon to the atmosphere (in the form of carbon dioxide) faster than natural processes can remove it. That's why the amount of carbon dioxide in the atmosphere is increasing, which is causing global climate change.

salt

When acid and base solutions react, they produce water and a neutral ionic compound called a salt.

Answer:

247.2g

Explanation:

Using the general gas law equation as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

According to the information in this question, a fuel tank contains 150. L (V) of H2 gas at 20.0 atm (P) at 25.0˚C (T)

Temperature = 25°C = 25 + 273 = 298K

Using PV = nRT

20 × 150 = n × 0.0821 × 298

3000 = 24.4658n

n = 3000/24.4658

n = 122.62

n = 122.6mol

Using the formula, mole = mass/molar mass, to find the mass of H2 gas.

Molar mass of H2 = 1.008(2)

= 2.016g/mol

122.6 = mass/2.016

mass = 122.6 × 2.016

mass = 247.2g.

Answer:

57.7 miles.

Explanation:

Hello there!

In this case, according to the given information, it is possible to set up the initial miles-cost ratio as shown below:

[tex]\frac{30mi}{\$2.60}[/tex]

Thus, we can find the the driven miles with $5 by multiplying as follows:

[tex]\frac{30mi}{\$2.60} *\$5\\\\=57.7mi[/tex]

Best regards!

The miles' the car can run with the fuel cost $5 has been 57.69 miles.

The given car run for a 30 miles by 1 gallon of the fuel. The given cost of fuel has been $2.60. Thus, for 30 miles, the cost of fuel has been driven to be $2.60.

The miles that can be driven by the car with $5 has been given by unitary method. The expression has been driven as:

[tex]\$2.60=30\;\rm miles\\\$5=\dfrac{30}{2.60}\;\times\;5\;miles\\\$5=57.69\;miles[/tex]

The miles' the car can run with the fuel cost $5 has been 57.69 miles.

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.

Answer: There are 0.000043 moles of melatonin.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]

given mass = 10 mg = 0.01 g

molar mass of [tex]C_{13}H_{16}N_2O_2[/tex] = 232.28 g

[tex]{\text {moles of melatonin}}=\frac{0.01g}{232.28g/mol}=0.000043moles[/tex]

Thus there are 0.000043 moles of melatonin

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

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
