When two atoms form a molecule, the molecule has lower energy than the two separate atoms. However, when only two atoms are present, they bounce off each other and do not form a molecule. Explain what happens to the energy of the atoms when there are only two atoms and they collide.
DONT GIVE ME A LINK!!
Answer:
they end up bouncing against each other instead of merging together
Explanation:
Identify two ways that temperature plays a role in chemical changes.
Answer:
Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.
Explanation:
Which statement is true in comparison to a weak acid, a strong acid
has a larger ph than weak acids
is more concentrated than we gases
strong acids produced less H plus ions is mostly H plus ions in solution
Answer: Strong acid vs weak acid
Strong acids and strong bases refer to species that completely dissociate to form ions in solution.
Explanation: By contrast, weak acids and bases ionize only partially, and the ionization reaction is reversible. Thus, weak acid and base solutions contain multiple charged and uncharged species in dynamic equilibrium.

Explanation:
An element is define as a substance which contains only those atoms which have same number of protons. Basically, an element contains atoms of one type only.
For example, a piece of sodium metal will contain only atoms of sodium.
An element can never be divided further into simpler substances. So, in the given figure box 1 is containing atoms of only blue color is an element.
A compound is a substance formed by the chemical combination of two or more different atoms present in a fixed ratio.
For example, [tex]MgCl_{2}[/tex] is a compound which contains atoms of Mg and Cl in a 1:2 ratio.
The box containing pink and yellow balls in not a compound because here atoms are not chemically combined to each other but they are just present as individual atoms in same box. Hence, this is not a compound.
Therefore, when one or more elements are in a fixed ratio joined together they form a compound.

How many moles of H2O are produced from 3 moles of oxygen? 2H2 + O2 --> 2H2O
Answer: 6 mol
Explanation:
From the equation, we know that for every mole of oxygen consumed, 2 moles of water are produced.
This means that if 3 moles of oxygen are consumed, 3(2) = 6 mol of water are produced.

An electric kettle uses electrical energy to boil water. Energy from the electricity is transferred to the water, heating it up. An electric ice maker also uses electrical energy, but it freezes water to form ice. Since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice, what happens to the energy put into the ice maker and the energy released by the water?
Answer:
Since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice. The energy remains electrical but then changes to kinetic when Enough energy is released.
Explanation:
Answer:
Explanation:
The overabundance of electrical energy acquired by water during the ice framing process is taken out as likely energy to keep up with the law of energy conservation. The electrical energy given to the ice generator pivots the engine inside the blower (compressor). The coolant available inside the blower is compressed and this pressure is accomplished alongside the creation of heat energy. The heat energy is delivered into the external encompassing air of the ice generator. This prompts a drop in the temperature of the coolant.
This coolant courses inside the ice generator and soaks heat energy (heat stream from the heater to the colder area) from the water as it gets once again to the blower, Thus prompting cooling of water and development of ice.

Two samples of hot unknown metals of equal temperatures are dropped in separate containers of water at 30 degrees Celsius. The final temperature of sample A is 33.5 degrees, and the final temperature of sample B is 31.8 degrees. Which metal sample had the highest specific heat?
Answer:
Sample B has the highest specific heat
Explanation:
Specific heat of a material is defined as the heat necessary to increase in the temperature of 1g of material in 1°C.
The material with the highest specific heat requires more energy to increase its temperature.
In the problem, sample A and B are under the same amount of energy but sample A increases more its temperature. That means sample A has the lowest specific heat and:
Sample B has the highest specific heatPLZ SOMEONE HELP I’LL MARK AS BRAINLIEST!!!
In an experiment 10 grams of a substance has a volume of 24 cm? What is the
substances' density ?
Answer:
[tex]d=0.417\ g/cm^3[/tex]
Explanation:
Given that,
Mass, m = 10 g
Volume, V = 24 cm³
We need to find the density of the substance. We know that, the density of a substance is given by :
Density = mass/volume
So,
[tex]d=\dfrac{10\ g}{24\ cm^2}\\\\d=0.417\ g/cm^3[/tex]
So, the density of the substance is [tex]0.417\ g/cm^3[/tex].

calculate the ph of the solution [oh-] = 1x 10-11 m
a. 11.0
b. 12.0
c. 2.7
d. 3.0
Answer:
d. 3.0
Explanation:
First we calculate the pOH of the solution, using the following formula:
pOH = -log[OH⁻]pOH = -log[1x10⁻¹¹ M]pOH = 11.0Using the pOH we can calculate the pH of the solution, keeping in mind the relationship between pH and pOH:
pH = 14.0 - pOHpH = 14.0 - 11.0pH = 3.0The answer is option d.

Iodine is prepared both in the laboratory and commercially by adding Cl2(g) to an aqueous solution containing sodium iodide. 2NaI(aq)+Cl2(g)⟶I2(s)+2NaCl(aq) How many grams of sodium iodide, NaI, must be used to produce 87.9 g of iodine, I2?
Answer:
[tex]m_{NaI}=104gNaI[/tex]
Explanation:
Hello there!
In this case, given the balanced chemical reaction, it is possible to evidence that the mole ratio of sodium iodide to iodine is 2:1 and the molar masses are 149.89 and 253.81 g/mol respectively; in such a way, we write the following stoichiometric setup in order to obtain the required grams of sodium iodide:
[tex]m_{NaI}=87.9gI_2*\frac{1molI_2}{253.81gI_2}*\frac{2molNaI}{1molI_2}*\frac{149.89gNaI}{1molNaI} \\\\m_{NaI}=104gNaI[/tex]

why methane and silicon dioxide have different melting point
Answer:
Methane is made up discrete molecules hence it adopts a simple molecular structure with weak vanderwaals forces of attraction while Silicon dioxide adopts a giant covalent structure with strong silicon to oxygen bonds.
Hence Silicon dioxide has a high melting point than methane.

Creativity is a phenomenon whereby something somehow new and somehow valuable is formed. The created item may be intangible (such as an idea, a scientific theory, a musical composition, or a joke) or a physical object (such as an invention, a printed literary work, or a painting).
Scholarly interest in creativity is found in a number of disciplines, primarily psychology, business studies, and cognitive science, but also education, the humanities, technology, engineering, philosophy (particularly philosophy of science), theology, sociology, linguistics, the arts, economics, and mathematics, covering the relations between creativity and general intelligence, personality type, mental and neural processes, mental health, or artificial intelligence; the potential for fostering creativity through education and training; the fostering of creativity for national economic benefit, and the application of creative resources to improve the effectiveness of teaching and learning.
