Which Of The Following Is Not A Balanced Nuclear Equation?O A) 130 Sn + B + 1315bd) 19Pt 158 Os+jac)

Answers

Answer 1

Answer:

¹⁰₄Be —> ¹⁰₃Li + ⁰₋₁β

Explanation:

To know which equation is unbalanced, we shall compare the mass number and atomic number of the reactant and product together. This is illustrated below:

¹²¹₅₀Sn —> ⁰₋₁β + ¹²¹₅₁Sb

121 = 0 + 121

121 = 121

50 = –1 + 51

50 = 51

Thus the above equation is balanced

¹⁹⁰₇₈Pt —> ¹⁸⁶₇₆Os + ⁴₂α

190 = 186 + 4

190 = 190

78 = 76 + 2

78 = 78

Thus, the above equation is balanced

¹⁰₄Be —> ¹⁰₃Li + ⁰₋₁β

10 = 10 + 0

10 = 10

4 = 3 + (–1)

4 = 3 – 1

4 = 2

Thus, the above equation is unbalanced.

²³⁸₉₂U —> ⁴₂α + ²³⁴₉₀Th

238 = 4 + 234

238 = 238

92 = 2 + 90

92 = 92

Thus, the above equation is balanced.

From the illustrations made above, only ¹⁰₄Be —> ¹⁰₃Li + ⁰₋₁β

Is unbalanced.

A piece of magnesium is in the shape of a cylinder with a height of 6.62 cm and a diameter of 2.34 cm. If the magnesium sample has a mass of 17.1 g, what is the density of the sample? (formula for volume of a cylinder: volume = r2h)

Answers

Answer:

0.600 g/cm³

Explanation:

Step 1: Given data

Height of the cylinder (h): 6.62 cmDiameter of the cylinder (d): 2.34 cmMass of the cylinder (m): 17.1 g

Step 2: Calculate the volume of the cylinder

First, we have to determine the radius, which is half of the diameter.

r = d/2 = 2.34 cm/2 = 1.17 cm

Then, we use the formula for the volume of the cylinder.

V= π × r² × h

V= π × (1.17 cm)² × 6.62 cm

V = 28.5 cm³

Step 3: Calculate the density (ρ) of the sample

The density is equal to the mass divided by the volume.

ρ = m/V

ρ = 17.1 g/28.5 cm³

ρ = 0.600 g/cm³

Two waves were analyzed with some high-tech instrumentation. The first wave was found to have a wavelength of 3 x 10 m and the second wave had a wavelength of 3 x 10 m. Which wave would have a higher frequency? Explain​

Answers

Explanation:

The first wave was found to have a wavelength of 3 x 10⁵ m and the second wave had a wavelength of 3 x 10⁴ m

We need to find which wave have a higher frequency.

The relation between frequency and wavelength is given by :

[tex]c=f\lambda[/tex]

Let f₁ and f₂ be the frequency of wave 1 and wave 2.

[tex]f_1=\dfrac{c}{\lambda_1}\\\\f_1=\dfrac{3\times 10^8}{3\times 10^5}\\\\=1000\ Hz[/tex]

And

[tex]f_2=\dfrac{c}{\lambda_2}\\\\f_2=\dfrac{3\times 10^8}{3\times 10^4}\\\\=10000\ Hz[/tex]

Hence, the wave having less wavelength will have higher frequency. The wave having wavelength 3 x 10⁴ m will have higher frequency.

What is a chemical equation?

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

How to write the net ionic equation

In solution

Fe₂(SO₄)₃ (aq) --> 2Fe³⁺(aq) + 3SO₄²⁻(aq)

KOH (aq) --> K⁺(aq) + OH¯(aq)

The reaction proceeds as follow

Fe₂(SO₄)₃ (aq) + KOH (aq) —>

Fe³⁺(aq) + SO₄²⁻(aq) + K⁺(aq) + OH¯(aq) —> Fe(OH)₃(s) + SO₄²⁻(aq) + K⁺(aq)

Cancel out the spectator ions (i.e SO₄²⁻ + K⁺) and balance to obtain the net ionic equation

Steel consumption increased when people started to use computers.

Answers

Answer:

A. Whenever the population has increased, steel consumption has increased as well.

Explanation:

Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen  on the graph is that whenever the population has increased, steel consumption has increased as well.

A critical look at the graph, you will discover that the population and the steel consumption are moving upwards (i.e they are increasing). It's seen that as the population increases, steel consumption increases. This is true because as the population increases, people are building houses, more transportation systems that require steel are being manufactured, more household utensils that are steel products are being fabricated etc; therefore the consumption of steel increases.

In the redox reaction, it is also known  

Reducing agents are substances that experience oxidation  

Oxidizing agents are substances that experience reduction

The metal activity series is expressed in voltaic series  

Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au  

The more to the left, the metal is more reactive (easily release electrons) and the stronger reducing agent  

The more to the right, the metal is less reactive (harder to release electrons) and the stronger oxidizing agent

So that the metal located on the left can push the metal on the right in the redox reaction  

The electrodes which are easier to reduce than hydrogen (H), have E cells = +

The electrodes which are easier to oxidize than hydrogen have a sign E cell = -

So the above metals or metal ions will reduce Pb²⁺ (aq) will be located to the left of the Pb in the voltaic series or which have a more negative E cell value (greater reduction power)

Answers

Answer:

The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.

Explanation:

In the catalytic converter, the oxidation number of nitrogen in NO changes from +2 to 0, and of carbon in CO changes from +2 to +4 as the reaction proceeds. Thus, option C is correct.

What is a catalytic converter?

The catalytic converter is a device used in vehicle exhaust to reduce the emission of toxic gas. The reaction in the device occurs to convert the nitric oxide into oxygen and nitrogen.

The redox reaction is given as,

2NO(g) + 2CO(g) → N₂(g) + 2CO₂(g)

In the reduction half of the reaction, the electrons are lost (addition of oxygen) like in carbon monoxide the oxygen is added that changes the number from +2 to +4. CO is a reducing agent that oxidized the carbon atom.

In the reduction half of the reaction, the oxygen is removed (electrons are added) and is shown by NO where the oxygen was lost to form N₂ with oxidation +2 to 0.

Therefore, option C. NO is a reducing agent that reduced nitrogen in the reaction.

The gravitational potential energy is due to the water overhead and the position of water inside the dam. The height and quantity of water determines the magnitude of the gravitational potential energy. Then, this energy is released when it falls on turbines and it drives them. As the turbine moves, mechanical energy is produced. The turbine is connected through a dynamo which produces a electric current by the turning action.
