cyanoacrylate
When cyanoacrylate polymerizes, the cyanoacrylate sticks together on an atomic level, and it becomes solid. Super Glue solidifies in all the microscopic crevices of an object that it moved into when it was a liquid, and it can form chemical bonds with any anions in the object.
Ensure you write the states of the reactants and products.

How many ml of a 2.903 M NaOH solution are needed to produce 500.0 ml of a 0.3344M solution?
Answer:
About 57.60 mL.
Explanation:
We can utilize the dilution equation:
[tex]\displaystyle M_1V_1 = M_2V_2[/tex]
Where M are the molarities of the solutions and V are the volumes of the solutions.
We want to determine the volume of a 2.903 M NaOH solution to mix in order to produce 500.0 mL of a 0.3344 M solution.
Substitute and solve for V₁:
[tex]\displaystyle \begin{aligned} (2.903 \text{ M})V_1 & = (0.3344 \text{ M})(500.0 \text{ mL}) \\ \\ V_1 & = 57.60\text{ mL} \end{aligned}[/tex]
In conclusion, 57.60 mL of a 2.903 M NaOH solution is needed.

A team of scientists is working to find the boiling point of a liquid at very low pressure. After three trials, the team has an average
of 12.3°C. An additional trial gives a result of 13.1°C. Which statement is a reasonable conclusion that can be drawn from this
result? (1 point)
O The original average should be thrown out because it could not be confirmed by new results.
O More data should be collected because the first three trials appear to be wrong.
O The original average should be used because it came from three results, not just one.
O More data should be collected to get a more reliable average.
Since it is conventional in science to use an average not just a single result, the original average should be used because it came from three results, not just one.
The boiling point refers to the temperature when the pressure of the fluid equals the atmospheric pressure. Hence, boiling occurs at atmospheric pressure.
In scientific experiments, it is common to conduct experiments more than once and obtain an average value for the measurement. In this case, the original average should be used because it came from three results, not just one.

activation energy in reaction is used to:
A- Overcome repulsion force between colliding molecules
B- Breaking bonds
C- Merge Valence electrons
D- All of them
Answer:
D — All of them
Explanation:
The activation energy in a reaction is the minimum amount of energy required for a chemical reaction to take place. Since all the options are processes in a chemical reaction, D should be the answer.

Which one item of the list below does not describe part of beta decay?
A. The nucleus of the atom is unstable.
B. A neutron turns into a proton.
C. A proton turns into an electron.
D. An electron is ejected from the nucleus.
Answer:
C
Explanation:
When Beta decay happens, the atomic number of an element goes up, and that means there is an extra proton. A is not the answer because unstable atoms cause decay. B is also not correct because this is what happens in Beta decay: a neutron becomes a proton. D is not correct because an electron is actually emitted from the nucleus.

Answer:
Coordinate-bond meaning
A type of covalent bond in which both the shared electrons are contributed by one of the two atoms. ... The definition of a coordinate bond is a chemical bond between two atoms when one of the atoms shares a pair of electrons.
Explanation:
Explanation:
is a covalent bond in the sharing of electron pair equally between two atoms in which each atom contribute an electron.
it is form when atomic orbitals of atoms each containing an unpaired electron overlap to share the pair of electrons.
What is a scientific law?
Answer:
Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. The term law has diverse usage in many cases across all fields of natural science.
Explanation:
I hope this helps
Answer:
Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. Scientific law differs from scientific theory. The main difference between a law and a theory is that a theory tries to explain the reasoning behind something that occurs in nature, whereas scientific laws are just descriptive accounts of how something occurs in nature.

To balance a redox reaction, what must be done?
The ion charge on both sides of the equation must equal zero.
Water must be added to both sides of the equation.
The increase and decrease in oxidation numbers must be balanced.
H+ and OH− must be added to opposite sides of the equation.
To balance a redox reaction, the increase and decrease in oxidation numbers must be balanced.
A redox reaction also called an oxidation- reduction reaction is a chemical reaction in which there is simultaneous gain and loss of electrons.
The species that loses electrons gets oxidized while the species that gains electrons gets reduced. This results in a change of oxidation number. The species that gets reduced decreases in oxidation number and the species that gets oxidized increases in oxidation number.
So, to balance a redox reaction, the simultaneous gain and loss of electrons must be balanced.
Thus, to balance a redox reaction, the increase and decrease in oxidation numbers must be balanced.
