The Quantum Mechanical model of electrons within an atom says______________
Answer:
See explanation
Explanation:
According to the wave mechanical model of the atom, electrons in the atom exhibit wavelike properties.
Unlike in Bohr's model where electrons were believed to be found in orbits of specified energy, electrons are found in orbitals which are defined as regions in space within which there is a high probability of finding an electron in accordance with the Heisenberg uncertainty principle.
An orbital is described by four sets of quantum numbers.

How many moles of carbon dioxide are formed when 32 moles of oxygen gas are consumed?
CH4(g) + 2O2(g) --> CO2(g) + 2H2O(g)
Answer:
16 mol CO2
Explanation:
Answer:
16 mol CO2
Explanation:
Based on the energy requirements or generation, reactions can be classified as either endothermic or exothermic. The reactions which need energy to proceed are known as endothermic reactions. The reactions in which energy is released are known as exothermic reactions. In other words, energy is supplied to endothermic reactions and is obtained from exothermic reactions.
The given reaction is:
CH_4 (g) + 2O_2 (g) -> CO_2 (g) + 2H_2O (g)
Here, methane reacts with oxygen to generate carbon dioxide and water.
The binding energy of a molecule is defined as the difference between energy of that molecule and its elements (in their ground state). The binding energy of the various species used in this reaction are:
methane: -75 kJ/mol
oxygen: 0
carbon dioxide: -394 kJ/mol
water: -242 kJ/mol
Thus, we can see that the formation of products will release more energy than reactants. We can also calculate the energy change when this reaction takes place.
Energy change = binding energy of products - binding energy of reactants
= -394 + 2 x (-242) - (-75) + 2 x 0 = -803 kJ/mol
negative sign indicates that the energy is released.
Thus, this reaction is exothermic and generates 803 kJ of energy per mole.
Hope this helps.

Make an equation
C, left = 2, right =2b⇒2b=2⇒b=1
Na, left = 2, right = c⇒c=2
O, left = 4+6a, right = 4b+3c⇒4+6a=4b+3c⇒4+6a=4.1+3.2⇒6a=6⇒a=1

Kinetic energy increases as________?
Answer:
THE 1st one
Explanation:
Large areas on the leaves of some plants lack chlorophyll and are therefore not green in color. How does this most likely affect photosynthesis?
Not enough sunlight is captured in these areas of the leaves.
Carbon dioxide cannot enter these areas of the leaves.
Too much glucose builds up in these areas of the leaves.
Oxygen cannot be released in these areas of the leaves
Answer:
Not enough sunlight is captured in these areas of the leaves.
Explanation:
Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water in the presence of sunlight.
The sunlight is the energy source which drives this chemical change or reaction.
Therefore, to capture the sunlight, the green pigment called chlorophyll is needed. Without this sunlight, photosynthesis will not take place. Photosynthesis is a light dependent reaction. Without light, the process is greatly hampered3rd law of thermodynamics..
2 Different Examples((Thnks))
Answer:
See explanation
Explanation:
The third law of thermodynamics states that "the entropy of a perfect crystal of a pure substance approaches zero as the temperature approaches zero" (Wikipedia).
One example of the third law of thermodynamics has to do with steam. Steam is gaseous water. Since it is a gas, its molecules are free to move around therefore its entropy is high. When the temperature of the steam is decreased below 100 degrees, the molecules of steam loose energy and turn into liquid water and do not move as freely as they did in the gaseous state. If the temperature is further decreased to yield ice at zero degrees, the molecules of water are "frozen" in their positions and the entropy of the system decreases to zero.
Also, the ions in ionic crystal solids move around when the substance is in solution or in molten state hence the substance conducts electricity. When the ionic substance is in solid state, the ions do not move about and the entropy of the solid system tends towards zero.
refers to the way in which atom bond with each other
Answer:
Atoms have a central nucleus with positively charged protons and neutral neutrons; negatively charged electrons circle the nucleus. The electrons that are involved in chemical bonding are those electrons in the outermost orbit, referred to as valence electrons.
Explanation:
Chemical bond refers to the way in which atom bond with each other
What is chemical bond?A chemical bond is a form of attraction or bond that exist between atoms, ions or molecules. This bond allows the formation of chemical compounds.
The bond can be as a result of electrostatic force of attraction.

Explanation:
If I fill a balloon with helium it will float. Why does it float? Estimate the mass of helium in the balloon.
Answer:
It only makes objects float if they are less dense than their surroundings, like a boat on water, or a helium balloon in air. Buoyancy works due to displacement. ... In the case of a balloon, the helium inside the balloon weighs less than the same volume of air the balloon displaces
Explanation:
Answer:
In the case of a balloon, the helium inside the balloon weighs less than the same volume of air the balloon displaces. ... So a helium balloon has two opposing forces acting on it: gravity pulling it down, and buoyancy pushing it up. Buoyancy wins, so you can't really weigh a balloon, even though it does have weight.
Knowing the volume of air displaced by the helium balloon, we can calculate the maximum mass the balloon can lift. ... Helium, which has a mass of 4.00 g/mol, has a density of 0.164 g/l. Thus, a one-liter balloon of helium can lift a mass of (1.18-0.164) = 1.02 g.
