Nobelium-254 has a half life of 3 seconds. How many half-lives would have to occur to
reduce a 15g sample down to 0.09375g?
the number of half-lives that would have occur to reduce a 15 g sample of Nobelium-254 down to 0.09375 g is 7.3
To calculate the number of half-lives that would have occur to reduce a 15 g sample of Nobelium-254 down to 0.09375 g, we use the formula below.
Formula:
2ⁿ = R/R'........... Equation 1Where:
n = Number of half-lives that have occuredR = Original mass of Nobelium-254R' = Mass of Nobelium-254 after decayFrom the question,
Given:
R = 15 gR' = 0.09375 gSubstitute these values into equation 1

The combination of fossil fuel use and deforestation has emitted approximately 480 gigatons of carbon over the last century, but the amount of carbon in the atmosphere has only increased by approximately 190 gigatons. About 110 gigatons of this missing carbon went into which reservoir of the carbon cycle?.
About 110 gigatons of this missing carbon went into water reservoir of the carbon cycle.
What is carbon cycle?The biogeochemical cycle in which carbon is exchanged between the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth is known as the carbon cycle.
According to the question, emitted amount of carbon is 480 gigatons but the amount of carbon in the environment is approx 190 gigatons, so the remaining amount of the carbon was stoored by the oceans and other water reservoir, which may be get clear throug the attached diagram.
Hence remaining gigatons of carbon went into water reservoir.

Explanation:
The forces of attraction that are present or exist between molecules of [tex]CH_2F_2[/tex] are as follows:
Dipole-dipole interaction.Hydrogen bonding.London Dispersion force. What is the Force of attraction?The force of attraction may be defined as a type of property that pulls the body towards its surface. It is the one through which atoms in molecules or elements are held together with different characteristics on the basis of their structure and functions.
It is known that fluorine has a higher electronegativity than carbon atoms. This difference in electronegativity is responsible for constructing a polar molecule. This significantly illustrates dipole-dipole interaction. It also demonstrates London-dispersion force which refers to the force between atoms and molecules.
It is a mechanism that overall represents the characteristics of each and every element specifically. The force of attraction governs the stability and functionality of the element and molecule as well.
Therefore, The forces of attraction that are present or exist between molecules of [tex]CH_2F_2[/tex] are Dipole-dipole interaction, Hydrogen bonding, and the London Dispersion forces.

The process that causes a spark to occur when the discharge wand is close to the Van de Graaff generator is similar to the process that causes lightning to form. Use what you have learned about the tendency of potential energy to decrease to try to explain how lightning occurs.
Answer:
Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud. When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud.
Explanation:
Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud.
What is a generator?In electricity generation, a generator is a device that converts motive power (mechanical energy) into electric power for use in an external circuit.
Lightning is an electric current. To make this electric current, a cloud is needed.
When the ground is hot, it heats the air above it. This warm air rises. As the air rises, water vapour cools and forms a cloud. When air continues to rise, the cloud gets bigger and bigger. In the tops of the clouds, the temperature is below freezing and the water vapour turns into ice.
Now, the cloud becomes a thundercloud. Lots of small bits of ice bump into each other as they move around. All these collisions cause a build-up of electrical charge.
Eventually, the whole cloud fills up with electrical charges. Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud.
When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud. This is like a static electricity sparks you see, but much bigger.
Hence, the positive and negative charges grow large enough, that a giant spark - lightning - occurs between the two charges within the cloud.

26. 8 g of ammonium chloride is dissolved in water to make a 0. 25 L solution. What is the molarity of the solution?
Answer: 0.5 M
Explanation:
Ammonium chloride has a gram formula mass of 53.49 g/mol, so 26.8 grams of ammonium chloride is 26.8/53.49 = 0.501 mol.
So since molarity = (moles of solute)/(liters of solution), the answer is 0.501 / 0.25 = 0.5 M
Determine the molarity of a solution formed by dissolving 3.00 moles of NaCl in enough water to yield 4.00 L of solution. 3.00 M 0.750 M 2.00 M 1.33 M 12.00 M
Taking into account the definition of molarity, the molarity of the solution formed by dissolving 3.00 moles of NaCl in enough water to yield 4.00 L of solution is 0.75 [tex]\frac{moles}{liter}[/tex].
Definition of molarityMolar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
[tex]Molarity=\frac{number of moles}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
Molarity in this caseIn this case, you know:
number of moles= 3 molesvolume= 4 LReplacing in the definition of molarity:
[tex]Molarity=\frac{3 moles}{4 L}[/tex]
Solving:
molarity= 0.75 [tex]\frac{moles}{liter}[/tex]
Finally, the molarity of the solution formed by dissolving 3.00 moles of NaCl in enough water to yield 4.00 L of solution is 0.75 [tex]\frac{moles}{liter}[/tex].
