This is a redox reaction but not a combustion reaction.
Redox Reaction
A type of chemical reaction that involves a transfer of electrons or gain of electrons between two-element. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes.
Combustion reaction
It must have two products. CO2 and H2Ooxygen in the reactant is must.
∴ The reaction is Redox ✓ not combustion

What is responsible for the unusual chemical properties of water?
Answer:
hydrogen bonds
Explanation:
pls choose it as brianliest
The unusual chemical properties of water is due to its polar covalent bond.
What is polar covalent bond ?When atoms with differing electronegativities are shared between two atoms in such a covalent link, the result would be a polar covalent bond.
What is water ?Water is a kind of mixture of hydrogen and oxygen . Its chemical formula will be [tex]H_{2}O[/tex].
Along with its polar covalent connections, water displays a variety of interesting features. Because oxygen has a higher electronegativity than hydrogen, electron pairs were drawn closer to the oxygen atom, causing it to be partially negatively charged. As a result, both hydrogen atoms acquire a slightly positive charge.
Therefore, polar covalent bond will be responsible for unusual chemical properties of water.

how does the solubility of oxygen in water affect the value of r you determined?
Answer:
R, the gas law constant, is a constant,
Solubility of gas is inversely proportional to temperature.
Solubility of gas ∝ 1/Temperature
That means as temperature increases the solubility gas goes on decreasing and vice versa.
But R is inversely proportional to temperature .
So Solubility ∝ R. (1/T ∝ R)
That means solubility of gas goes on increasing as R increases.
Step 2: Result
Result:
So from above conclusion the solubility of Oxygen in water increases that result into increasing R value.

Look at the three kinds of houses shown in the simulation. Which house do you think will best resist damage from a tsunami? Which house will suffer the most damage from a tsunami? Do you think any of the houses will survive a large tsunami? Write down your predictions.
Answer:
The brick house will best resist damage from a tsunami, and the straw house will suffer the most damage from a tsunami. I predict these reasons because brick has a stronger material than the rest of the houses, while the straw house has the weakest material than the rest of the houses. No, I do not think any of the houses can survive a massive tsunami because if the tsunami was 22 feet tall, the brick house would become damaged due to the lack of support. And, the other houses can't take a tsunami higher than 10 feet. The brick house can only take tsunamis less than 20 feet.

what is neutralisation??
Answer:
Acid + Base -------> Salt + Water
Explanation:
The reaction between an acid and bases is called a neutralization reaction. The result of the reaction is salt and water. For example, when hydrochloric acid(acid) and sodium hydroxide(base) react they form sodium chloride(salt) and water. Also, heat is evolved.
Example:
HCl + NaOH ----------> NaCl + H2O
HCl is hydrochloric acid.
NaOH is sodium hydroxide which is a base.
NaCl is sodium chloride which is a salt.
H2O is water.
Magnesium (24.30) reacts with hydrogen chloride (X g) to produce hydrogen gas (2.04 g) and magnesium chloride (96.90 g). How much hydrogen chloride was used in the reaction?
Round your answer to the second decimal.
Answer:
Hydrogen Chloride is 74.64 grams.
Explanation:
Using the given information, we can find the amount of grams of hydrogen chloride that take place in the reaction.
24.30 grams of Magnesium"x" grams of Hydrogen chloride2.04 grams hydrogen gas96.90 grams of magnesium chloride.Due to the Law of Conservation of Mass, the mass of the system must remain constant. To find the value of x, make the equation below.
[tex]24.30 + x=2.04 + 96.90[/tex]
The left side represent the reactant side of the chemical reaction and the right side represents the product side.
[tex]2.04 + 96.90= 98.94[/tex]
[tex]24.30+x=98.94[/tex]
[tex]24.30 - 24.30 + x= 98.94 - 24.30[/tex]

Explain The element lithium has two common isotopes: Li–6 and Li–7 If the average atomic mass of lithium is 6.94004 u, determine its percent isotopic step by step please urgently
Answer:
%Li-6 = 5.996% & %Li-7 = 94.004%
Explanation:
let X₁ = Li-6 & X₂ = Li-7 where Xₙ = mole fraction
X₁ + X₂ = 1 => X₁ = 1 - X₂
6·X₁ + 7·X₂ = 6.94004
=> 6(1 - X₂) + 7·X₂ = 6.94004
=> 6 - 6·X₂ + 7·X₂ = 6.94004
=> 6 + X₂ = 6.94004
X₂ = 6.94004 - 6 = 0.94004 => %X₂ = %Li-7 = 94.004%
X₁ = 1.00000 - 0.94004 = 0.05996 => %X₁ = %Li-6 = 5.996%

Part D: Bohr’s Atomic Model Question 1 Using what you can recall from this unit, write one or two short paragraphs describing Niels Bohr’s atomic model. If needed, you may search the Internet for descriptions of the model.
Answer:
The Bohr Model is a planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun (except that the orbits are not planar). The gravitational force of the solar system is mathematically akin to the Coulomb (electrical) force between the positively-charged nucleus and the negatively-charged electrons.
Main Points of the Bohr Model
Electrons orbit the nucleus in orbits that have a set size and energy.
The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.
Radiation is absorbed or emitted when an electron moves from one orbit to another.
Have a great day friend! :D
A small positive charges nucleus is encircled by revolving negatively charged electrons in fixed orbits, according to the Bohr Atomic model.
What are the drawbacks of Bohr’s Atomic Model?The atom is basically depicted in the Bohr model as a central nucleus containing protons along with neutrons, with electrons in circular orbitals at various distances from the nucleus.
These orbits combine to form electron shells or energy levels, which allow you to see how many electrons are in each shell.
He concluded that electrons have more energy when they are located away from the nucleus, whereas electrons have less energy when they are located near the nucleus.
He was unable to explain the specifics of the Hydrogen and Helium atomic spectrums.
He did not explain how spectral lines split in the presence of a magnetic field. He did not explain the intensity of spectral lines.
Thus, these can be concluded regarding the Bohor's atomic model.

An alkyne with the molecular formula C5H8 was reduced with H2 and Lindlar's catalyst. Hydroboration-oxidation of the resulting alkene afforded a primary alcohol. What is the IUPAC name of the alkyne starting material
Since the addition of the H2O in the last step of hydroboration is anti-Markovnikov, the starting material is 1-pentyne.
The addition of H2 to C5H8 yields an alkene when a Lindlar catalyst is used. Recall that the Lindlar catalysts poisons the process so that the addition do not go on to produce an alkane.
When hydroboration is carried out on the alkene, we are told that a primary alcohol was obtained. We must note that in the last step of hydroboration, water is added in an anti- Markovnikov manner to yield the primary alcohol. Hence, the starting material must be 1-pentyne as shown in the image attached.

Answer:
J.J. Thomson's experiments with cathode-ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. I would describe the structure of an atom as the plum pudding model.

Answer:
Pb[lead] [Xe]4f^145d^106s^26p^2
U[uranium] 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4e^14 5d^10 6p^6
7s^2 5f^4
This notation can be written in core notation or noble gas notation by replacing the
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4e^14 5d^10 6p^6

Ti:1s^2 2s^2 2p^6 3s^2 3p^6 3d^2 4s^2
1s^2 2s^2 2p^6 3s^2 3p^5 = 17 electrons
(1) electron gain will result to a
negative charge (−), and
(2) electron loss will result to a positive charge (+),
1s^2 2s^2 2p^6 3s^2 3p^6 = 18 electrons
Hg[mercury] You should then find its atomic number is 80. It has a Xe core, so in shorthand notation, you can include [Xe]instead of
1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 4d^10 5s^2 5p^6,
for 54 electrons. For the 6th row of the periodic table, we introduce the 4f orbitals, and proceed to atoms having occupied 5d orbitals. We, as usual, have the ns orbitals, and n=? for the 6th period?
