Based on table N of the reference tables what is the number of hours required for 42k (potassium -42) to undergo three half-life periods
The number of hours required : 37.2 hours
Further explanationGiven
⁴²K (potassium -42)
Required
The number of hours
Solution
The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually, radioactive elements have an unstable atomic nucleus.
Based on Table N(attached), the half-life for ⁴²K is 12.4 hours, which means half of a sample of ⁴²K will decay in 12.4 hours
For three half-life periods :
[tex]\tt 3\times 12.4=37.2~hours[/tex]
How many atoms of the element with atomic number 11 are in the reactants of the given formula?
2 NaCl + H2SO4 → 2 HCl + Na2SO4
The number of Na atoms in the reactants = 2
Further explanationEvery chemical reaction involves compounds that can act as reactants or products
The reactants will react to produce products
The reactants are usually written on the left side of the reaction, while the products on the right side of the reaction
Reaction
2 NaCl + H₂SO₄ → 2 HCl + Na₂SO₄
The element with atomic number 11 = Na(Natrium)
The number of atoms of the element that reacts or is produced can be seen from the reaction coefficient and the number of atoms in the compound
Na in NaCl = 1 atom
From equation, cofficient for NaCl = 2, so number of atoms of Na=2 x 1 = 2

Compare the potential energy of two atoms chemically bonded to their potential energy when separated.
Answer:
See explanation
Explanation:
The essence of chemical bonding is in order to attain minimum energy. The minimum energy state is the most stable state of a chemical system.
As the distance of separation between atoms decreases, the potential energy of the system decreases accordingly.
An optimum distance is reached when the two atoms attain the lowest potential energy. This is designated as the bond distance of the two atoms.
Hence two atoms have lower potential energy when bonded than when separated at large distance.
When two atoms are chemically bonded they have Lower potential energies while when they are separated they have higher potential energies
The potential energies of atoms chemically bonded is directly proportional to the distance between the atoms ( i.e as the distance between atoms decrease the potential energies of the atoms decreases accordingly) and this enables chemically bonded atoms to attain a more stable state.
The lower the potential energy of bonded atoms the more stable the element/compound becomes therefore it is necessary that bonded atoms attain the least possible potential energy.
Hence we can conclude that When two atoms are chemically bonded they have Lower potential energies while when they are separated they have higher potential energies .

How do we get heat from the sun?
Answer:
When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.
Explanation:
Answer:
The sun radiates energy in all directions. Most of it dissipates into space, but the tiny fraction of the sun's energy that reaches Earth is enough to heat the planet and drive the global weather system by warming the atmosphere and oceans. The delicate balance between the amount of heat Earth receives from the sun and the heat that Earth radiates back into space makes it possible for the planet to sustain life.

1. Suppose that there were two isotopes of Sodium.
28% of the naturally occurring sodium atoms had a
mass of 22, and 72% atoms had a mass of 23. What
would the average atomic weight of sodium be?
Answer: C. The university surveys 600 randomly selected students who attend the university. Correct
Explanation:
22.72 is the average atomic weight of sodium.
What are isotopes?Isotopes are different versions of a specific element.
1st isotopes of 22u = 28%
2nd isotopes of 23u = 72%
The average atomic weight of sodium be=
22 x 28 + 23 x72
=2272/100
=22.72
Hence, 22.72 is the average atomic weight of sodium.

Explain the electroplating process of an iron key with silver. the materials provided for electroplating is AgNO3 solution, silver rod and iron key.
Answer:
See explanation
Explanation:
The process of electroplating an iron key with silver involves electrolysis.
The anode is a silver rod, the electrolyte is AgNO3 solution while the cathode is the iron key. A battery is connected to provide energy to drive the non-spontaneous electrochemical reaction.
Electrons flow from the anode to the cathode. Silver ions from the silver rod replenishes the silver that is deposited on the iron key in order to continue the electrolytic process.
The silver anode is therefore depleted in mass while the iron key increases in mass.

During a chemical or physical change, energy may be...
a. created into another form
b. destroyed and reinvented into another form
c. converted into another form
d. disappeared
Answer: C: Converted into another form
Explanation: pues es esa calale y si va a hacer
During a chemical or physical change, energy is converted to another form. Energy cannot be created or destroyed. During a chemical reaction, physical change the energy and mass are conserved.
What is law of conservation of energy ?According to the law of conservation of energy energy can neither be crated nor be destroyed. Hence, the total energy of a system is always conserved.
However, energy can be transformed from one form to the other. Therefore, the energy lost in one form is gained in another form. For example, in all electrical devices, the electrical energy is converting to other forms of energy such as light, thermal , mechanical etc.
Similarly, during a chemical reaction, the energy released by a reaction system is equal to the energy absorbed by other reacting system. Similarly in electrochemical cells the chemical energy is converting to electrical energy.

Explanation:
If 50. mL of 1.0 M NaOH is diluted with distilled water to a volume of 2.0 L, the concentration of the resulting solution is A0.025 M B 0.050 M C 0.10 M D 0.50 M E 1.0 M M
Answer: The concentration of the resulting solution is 0.025 M
Explanation:
According to the dilution law,
[tex]M_1V_1=M_2V_2[/tex]
where,
[tex]M_1[/tex] = molarity of concentrated [tex]NaOH[/tex] solution = 1.0 M
[tex]V_1[/tex] = volume of concentrated [tex]NaOH[/tex] solution = 50 ml
[tex]M_2[/tex] = molarity of diluted [tex]NaOH[/tex] solution = ?
[tex]V_2[/tex] = volume of diluted [tex]NaOH[/tex] solution = 2.0 L = 2000 ml (1L=1000ml)
Putting in the values we get:
[tex]1.0\times 50=M_2\times 2000[/tex]
[tex]M_2=0.025M[/tex]
Therefore, concentration of the resulting solution is 0.025 M
The concentration of the resulting solution if 50. mL of 1.0 M NaOH is diluted with distilled water to a volume of 2.0 L is 0.025M
HOW TO CALCULATE FINAL CONCENTRATION:
The concentration of a solution can be calculated by using the following formula:C1V1 = C2V2
Where;
C1 = initial concentration (M)C2 = final concentration (M)V1 = initial volume (L)V2 = final volume (L)According to this question;
C1 = 1.0MV1 = 50mLC2 = ?V2 = 2000mL = 2L1 × 50 = C2 × 200050 = 2000C2C2 = 50 ÷ 2000C2 = 0.025MTherefore, the concentration of the resulting solution if 50. mL of 1.0 M NaOH is diluted with distilled water to a volume of 2.0 L is 0.025M.Learn more at: https://brainly.com/question/17329736?referrer=searchResults
