Explanation:
A neutralization reaction is a reaction that involves an acid and a base.
When an acid reacts with a base to produce salt and water only, the reaction is said to be a neutralization reaction.
Acid + Base → Salt + Water
Such reactions are classified as a double displacement reaction in which a non-ionizing product is formed

C3H8 + 5O2 → 3CO2+ 4H2O, if 5.75L of oxygen are consumed in the above reaction, how many L of carbon dioxide are produced?
Answer: 3.45 L carbon dioxide are produced
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar volume}}=\frac{5.75L}{22.4L}=0.257moles[/tex]
[tex]C_3H_8+5O_2(g)\rightarrow 3CO_2+4H_2O[/tex]
According to stoichiometry :
5 moles of [tex]O_2[/tex] produce = 3 moles of [tex]CO_2[/tex]
Thus 0.257 moles of [tex]O_2[/tex] will produce=[tex]\frac{3}{5}\times 0.257=0.154moles[/tex] of [tex]CO_2[/tex]
Volume of [tex]CO_2=moles\times {\text {Molar volume}}=0.154moles\times 22.4L/mol=3.45[/tex]
Thus 3.45 L carbon dioxide are produced

Explanation:
Find the mass of 1.25 moles Ca(OH)2.
According to the mole concept, the mass of 1.25 moles Ca(OH)₂ is 92.61 grams.
What is a mole?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.Mass=number of moles×molar mass=1.25×74.09=92.61 g.
Thus,the mass of 1.25 moles Ca(OH)₂ is 92.61 grams.

Which object has a tail when it passes near the Sun?
A. Comet
B. Meteor
C. Moon
D. Asteroid
Answer:
A. Comet
Explanation:
Comet is a object which has a tail when it passes near the Sun.
What is a comet?A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma.
These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit.

how many significant figures are needed in the answer when 1.31m is multiplied by 6.5 m
Answer:
two
Explanation:
The number of significant figures needed in the answer is 2.
This is because when finding the products of two numbers, the result is as accurate as the least number of significant figures of the numbers being multiplied.
Here the numbers being multiplied are;
1.31m
6.5m
1.31m has 3 significant figures
6.5m has 2 significant figures.
So, the product will have 2 significant figures

If more solvent is added to a solution:
A.the solution becomes less dilute
B.the molarity decreases
C.the molality increases
D.the percent (v/v) increases
Answer:
The answer would be A
Explanation:
If more solvent is added, the solution becomes unsaturated because in principle it is capable of dissolving more solute.
How does salinity vary with freezing and melting?
Question 3 options:
Freezing increases salinity, while melting decreases salinity.
Both freezing and melting decrease salinity.
Freezing decreases salinity, while melting increases salinity.
Both freezing and melting increase salinity.
Answer:
For every 5 psu increase in salinity, the freezing point decreases by 0.28 degrees Celsius (0.5 degrees Fahrenheit); thus, in polar regions with an ocean salinity of about 32 psu, the water begins to freeze at -1.8 degrees Celsius (28.8 degrees Fahrenheit).
Explanation:
Freezing increases salinity, while melting decreases salinity.

Further explanationGiven
Reaction
Al₂(CO₃)₃ → Al₂O₃ + 3CO₂
Required
Type of reaction
Solution
The decomposition reaction in a chemical reaction shows the decomposition reaction of a compound into its constituent elements or compounds
So 1 compound breaks down into 2 or more compounds
The general formula :
AB ⇒ A + B
What is the overall reaction equation
Answer:
If m or n is zero, the reaction is zero order in A or B, respectively, and the rate of the reaction is not affected by the concentration of that reactant. The overall reaction order is the sum of the orders with respect to each reactant. If m = 1 and n = 1, the overall order of the reaction is second order
(m + n = 1 + 1 = 2).
