what is the half life of the element in the picture

HELP BRAINLIEST

Answers

Answer:

6 days

Explanation:

The following data were obtained from the question:

Original amount (N₀) = 100 mg

Amount remaining (N) = 6. 25 mg

Time (t) = 24 days

Half life (t½) =?

Next, we shall determine the decay constant. This can be obtained as follow:

Original amount (N₀) = 100 mg

Amount remaining (N) = 6. 25 mg

Time (t) = 24 days

Decay constant (K) =?

Log (N₀/N) = kt / 2.303

Log (100/6.25) = k × 24 / 2.303

Log 16 = k × 24 / 2.303

1.2041 = k × 24 / 2.303

Cross multiply

k × 24 = 1.2041 × 2.303

Divide both side by 24

K = (1.2041 × 2.303) / 24

K = 0.1155 /day

Finally, we shall determine the half-life of the isotope as follow:

Decay constant (K) = 0.1155 /day

Half life (t½) =?

t½ = 0.693 / K

t½ = 0.693 / 0.1155

t½ = 6 days

Therefore, the half-life of the isotope is 6 days

Explanation:

The terms distance and displacement are used by scientists to describe very specific differences between an object's initial position and its final position. Describe a situation in which the distance traveled is great but the displacement is zero.

Answers

Explanation:

Distance is the total length of path one travels.

Displacement is the distance between the initial and final position.

 For example, if your classroom is located 200m from your dormitory, you walk to class and back to your dormitory, your distance is 200m + 200m  = 400m;

  Your displacement is 0m. Your initial and final position is the same so no displacement.

If an unknown solution has a pH of 9, what is that solution classified as?
A.Solid
B.Neutral
C.acid
D.Base​

Answers

Answer:

option A is the ans i think so

If an unknown solution has pH of 9 the solution is classified as a base as it has larger concentration of hydroxyl ions.

What is base?

According to the Arrhenius concept, base is defined as a substance which yields hydroxyl ions on dissociation.These ions react with the hydrogen ions of acids to produce salt in an acid-base reaction.

Bases have a pH higher than seven as they yield hydroxyl ions on dissociation.They are soapy in touch and have a bitter taste.According to the Lowry-Bronsted concept, base is defined as a substance which accepts protons .Base react violently with acids to produce salts .Aqueous solutions of bases can be used to conduct electricity .They can also be used as indicators in acid-base titrations.

They are used in the manufacture of soaps,paper, bleaching powder.Calcium hydroxide ,a base is used to clean sulfur dioxide gas while magnesium hydroxide can be used as an antacid to cure acidity.

What are the coefficients when the equation below is balanced?

Answers

Answer:

1, 2, 2, 1

Explanation:

This is basically the equation we're trying to balance:

Cu + AgNO₃ → Ag + Cu(NO₃)₂

We start with Copper (Cu): There is 1 atom on the reactants'(left) side and 1 atom on the products'(right) side which means it's balanced

The second is Silver (Ag): There is 1 atom on the reactants' side and 1 atom on the products' side which means it's balanced

The third is Nitrogen (N) and there is 1 atom on the reactants' side and 2 atoms on the products' side. We balance it by multiplying the reactants' side by 2

Cu + 2AgNO₃ → Ag + Cu(NO₃)₂

Silver is now imbalanced so we multiply the silver atoms on the product's side by 2

Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂

If you count them now, the atoms on each side are the same number

1 Copper atom on each side

2 Silver atoms on each side

2 Nitrogen atoms on each side

6 Oxygen atoms on each side (2 sets of 3 oxygen atoms)

1Cu + 2AgNO₃ → 2Ag + 1Cu(NO₃)₂

What is the energy of a wave with a wavelength of 2.25 nm?

Answers

The energy of a wave : 8.835.10⁻¹⁷ J

Further explanation

The energy in one photon can be formulated as

E = h. f

Where

h = Planck's constant (6.626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

f = c / λ

c = speed of light

= 3,10⁸  m/s

λ = wavelength

λ = wavelength  of a wave = 2.25 nm = 2.25 x 10⁻⁹m

[tex]\tt E=h.\dfrac{c}{\lambda}\\\\E=6.626.10^{-34}\times \dfrac{3.10^8}{2.25.10^{-9}}\\\\E=8.835\times 10^{-17}~J[/tex]

20 ML of a gas at 200 K is heated until the new volume is 55ML what is the final temperature of the gas

Answers

Answer:

T2 = 550K

Explanation:

From Charles law;

V1/T1 = V2/T2

Where;

V1 is initial volume

V2 is final volume

T1 is initial temperature

T2 is final temperature

We are given;

V1 = 20 mL

V2 = 55 mL

T1 = 200 K

Thus from V1/T1 = V2/T2, making T2 the subject;

T2 = (V2 × T1)/V1

T2 = (55 × 200)/20

T2 = 550K

As you move from left to right across the second period of the periodic table

A. Ionization energy increases
B. Atomic mass decreases
C. Electronegativity decreases
D. Atomic radii increase

Answers

Answer:

A. ionizing energy increases

A tabular form in which the chemical elements are positioned according to the chemical and physical attributes is called the periodic table. The horizontal rows from left to right is referred as periods in the table.

The correct option is:

Option A. Ionization energy increases

This can be explained as:

The ionization energy raises from left to right because of valence shell resilience.

The nuclear charge on the atom expands and protons in the nucleus lure the electrons more strongly.

Therefore due to the high proton number, the ionization increases across the period.

explain that atoms of elements combine to make compounds

explain why there are many, but limited, combinations of elements to make compounds

demonstrate with atomic models how atoms can combine in many ways

Answers

Answer:

Explanation:

Any substance that contains only one kind of an atom is known as an element. Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P4) or sulfur (S8) cannot be broken down into simpler substances by these reactions.

Example: Water decomposes into a mixture of hydrogen and oxygen when an electric current is passed through the liquid. Hydrogen and oxygen, on the other hand, cannot be decomposed into simpler substances. They are therefore the elementary, or simplest, chemical substances - elements.

Each element is represented by a unique symbol. The notation for each element can be found on the periodic table of elements.

The elements can be divided into three categories that have characteristic properties: metals, nonmetals, and semimetals. Most elements are metals, which are found on the left and toward the bottom of the periodic table. A handful of nonmetals are clustered in the upper right corner of the periodic table. The semimetals can be found along the dividing line between the metals and the nonmetals.

Answer:

B.) kinetic energy from wind turns blades on wind turbine → wind turbine blades turn generator → generator changes kinetic energy to electricity

Explanation:

correct on edge

just took the quiz

The correct order of steps when using wind to generate electricity is kinetic energy from wind turns blades on wind turbine → wind turbine blades turn generator → generator changes kinetic energy to electricity. Therefore, option B is correct.

What do you mean by the kinetic energy ?

The energy an item has as a result of motion is known as kinetic energy. A force must be applied to an item in order to accelerate it. We must put forth effort in order to apply a force.

Kinetic energy has the following formula: K.E. = 1/2 mv², where m is the object's mass and v is its square velocity.

The kinetic energy is measured in kilograms-meters squared per second squared if the mass is measured in kilogrammes and the velocity is measured in metres per second.

The steps when using wind to generate electricity is kinetic energy from wind turns blades on wind turbine → wind turbine blades turn generator → generator changes kinetic energy to electricity.

Thus, option B is correct.

Explain in words or using your diagrams how beryllium atoms would react with fluorine atoms.
Show clearly the outcome of the reaction and state the formula.

Answers

Explanation:

To delineate the the nature of the bonds that would be formed between the two elements, let us first write the electronic configuration of the two species;

  Be  = 2, 2

  F  = 2, 7

 Beryllium is a metal with two valence electrons whereas fluorine is a halogen with seven valence electrons.

When Be loses two electrons it becomes isoelectronic with He;

                 Be →  Be²⁺ + 2e⁻  

Also, when fluorine gains  an electron, it becomes isoelectronic with Ne;

               F  + e⁻ →  F⁻

This loss and gain of electrons between the two elements creates an electrostatic attraction them and they enter into an electrovalent bond.

      Hence;

           Be²⁺  + 2F⁻ → BeF₂
