We can verify the properties as follows;
1) Sour taste - Put some soda on your tongue
2) Corrode metals - Put a little soda on a clean metal surface
3) Effect on Litmus paper - Dip a blue litmus paper in soda
4) Electrolysis - Add two electrodes to soda and connect a battery.
Does Soda show acidic properties?Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.
When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:
CO₂ + H₂O ⇌ H₂CO₃

When a solid with a mass of 53.78 g is added to 50.0 ml of water in a graduated cylinder, the volume increases to 56.4 ml. Calculate the density of the solid.
Answer:
The answer is 8.40 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
volume = final volume of water - initial volume of water
volume = 56.4 - 50 = 6.4 mL
We have
[tex]density = \frac{53.78}{6.4} \\ = 8.403125[/tex]
We have the final answer as
8.40 g/mLHope this helps you

In ecosystem, particles are carried as bed load by rubbing particles together.Path of stream can be varied depending on amount of humus present in soil and is measured in cubic meters per second and carrying capacity depends on type of material through which stream flows.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

2 Na (s) + Cl2 (g) → 2 NaCl (s) is an example of a physical or chemical change?
Answer:
Chemical change.
Explanation:
Physical Change
The changes that occur only due to change in shape or physical properties but their chemical or internal composition remain unchanged.
Example :
Water converting to Ice
Water converting to gas
In this water molecule remain the same only they rearrange themselves that change its state of mater not composition
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Example:
Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood
The reaction of between sodium and chlorine:
2Na(s) + Cl₂(g) -------------------------------------> 2NaCl(s)

What is the opposite force to pushing off the ground to jump?
Answer:
Newton's Third Law of Motion states that to every action there is an equal and opposite reaction. When the earth pushes on you to send you into the air after jumping, you also push on the earth with the same force. But forces are different from accelerations. A force F is a push or pull on an object
Explanation:
Answer:
Friction
Explanation:
Friction causes an opposite force

The diagram above shows the distribution of speeds for a sample of N2(g)
at 25°C
. Which of the following graphs shows the distribution of speeds for a sample of O2(g)
at 25°C
(dashed line) ?
Answer:
A
Explanation:
The Maxwell-Boltzmann equation, is the basis for discussion of the kinetic theory of gases. From it we can understand how gases are distributed at a particular temperature.
Let us remember that the kinetic energy of all gases is the same at the same temperature. However, the distribution of gases depends on their molecular weight at that particular temperature.
Heavier molecules are known to move slowly compared to lighter molecules. Heavier molecules generally have a smaller distribution while lighter molecules spread out.
For this reason, oxygen which is heavier than nitrogen has a smaller distribution as shown in the diagram (molar mass of oxygen = 32g/mol) while nitrogen (molar mass 28 g/mol) has a distribution that is more spread out being a lighter molecule. Hence the option chosen.

Arrange the following elements in order from least to greatest electronegativity:
Ca, F, Ne, Fe?
Answer:
The electronegativity from order of least to highest is:
Ne, Ca, Fe, F
Explanation:
Elements in the periodic table have been arranged based on their level of electronegativity (which is the ability of an atom to attract electrons).
According to Paulings scale of rating elements based on their electronegativity, the electronegativity value of Fe, Ca, Ne, and F are 1.83, 1, 0 and 3.98 respectively.
Hence, based on Pauling scale, the order of electronegativity from least to highest is:
Ne > Ca > Fe > F

How much energy is required to raise the temperature of 0.2 kg of aluminum from 15°C to 18°C? (Refer to table of specific heat values.)
The amount of energy which is required to raise the temperature of 0.2 kg of aluminum from 15°C to 18°C is 49,545 J.
How do we calculate absorbed energy?Amount of energy absorbed by any material will be calculated by using the below equation:
Q = mcΔT, where
m = mass of aluminum = 0.2 kg
c = specific heat of aluminum = 897 J/kg.K
ΔT = change in temperature = 18 - 15 = 3°C = 276.15 K
On putting these value on the above equation, we get
Q = (0.2)(897)(276.17) = 49,544.89 = 49,545 J
Hence required amount of energy is 49,545 J.
