Calculate the concentration of
5 g of sugar dissolved in 20 cm of water

The product of the reaction will be polar in nature due to the bonds formed between hydrogen and oxygen or nitrogen.

The product of a chemical reaction is the substance which is formed at the end of the reaction by the reactant or reactants.

The product of a reaction can be formed from the rearrangement of atoms in a compound due to changes in the environment of that compound.

The product can also be formed by the addition or removal of atoms of the reactants.

In the example above, no reactant is shown, however the bonds formed between hydrogen and oxygen or nitrogen gives polarity to the product formed.

Hence, a reactant must be present for a product to be formed.

Explanation:

For the solubility of a gas is 0.890 g/L at a pressure of 120 kPa, the solubility of the gas, if the pressure is changed to 100 kPa is mathematically given as

c=0.741g/l

Generally, the equation for the Pressure   is mathematically given as

p=kc

Therefore

k=p/c

k = 120 /0.890

k=134.8

In conclusion, if p=100kpa

c=p/k

c=100/134.8

c=0.741g/l

concentration [H_3O^+][H3O+] decreased by 4.46334\sdot10^{-4}M.4.46334⋅10−4M.

Explanation:

pH=−log[H3O+]; [H_3O^+]=10^{-pH};[H3O+]=10−pH;

If pH=3.350;pH=3.350;

[H_3O^+]=10^{-3.35}=4.467\sdot10^{-4}M;[H3O+]=10−3.35=4.467⋅10−4M;

If pH=6.780;pH=6.780;

[H_3O^+]=10^{-6.78}=1.66\sdot10^{-7}M;[H3O+]=10−6.78=1.66⋅10−7M;

4.467\sdot10^{-4}-1.66\sdot10^{-7}=4467\sdot10^{-7}-1.66\sdot10^{-7}=4465.34\sdot10^{-7}=4.467⋅10−4−1.66⋅10−7=4467⋅10−7−1.66⋅10−7=4465.34⋅10−7=

Explanation:

low or no reactivity ....

Neon and argon are both in Group 18 of the periodic table. The property that they are most likely to share is low or no reactivity. The correct option is d.

A chemical element found in the periodic table is argon. It is the third most common gas in the atmosphere and has an atomic number of 18.

In the periodic table, neon is a chemical element. It is a monatomic, noble gas with the atomic number 10 that is found in the environment.

Although a few liquid molecules do rise to the top, the vast majority stay close to the bottom. Furthermore, the molecules in the gas phase move more swiftly than those in the liquid phase.

Therefore, the correct option is d, low, or no reactivity regarding the mutual property of argon and neon.

The option that would be best for making Julia model look more like a plant cell is putting the bag inside a larger clear plastic bag.

A cell is the basic and functional unit of life. Every living organism is made up of one or more cells.

However, a plant cell is morphologically different from an animal cell. One of the major differences is that a plant cell posseses a cell wall that protects the cell.

According to this question, Julia made a model of a cell in a clear plastic zipper bag. She used a marble for the nucleus and pinto beans for mitochondria.

Therefore, the option that would be best for making Julia model look more like a plant cell is putting the bag inside a larger clear plastic bag which will represent the cell wall.

Combined gas law put together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.

It is expressed as;

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]

To calculate the new volume the gas occupy, we subtsitute our given values into the expression above.

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}\\ \\ P_1V_1T_2 = P_2V_2T_1\\\\0.750atm * 8.20L * 325K = 1.075atm * V_2 * 375K\\\\1998.75LatmK = 403.125atmK * V_2\\\\V_2 = \frac{1998.75LatmK}{403.125atmK} \\\\V_2 = 4.96L[/tex]

Explanation:

According to kinetic molecular theory,changes of the state of matter occur when energy is added or removed from a substance

According to the Kinetic-Molecular Theory, changes of the state of matter occur when energy is added or removed from a substance. The addition of energy makes particles move more, pushing them apart and weakening the bonds between them. Removing energy makes particle movement slow down, re-forming the bonds.

Answer:

.0139

Explanation:

The number of moles of HCl would take to neutralize the sodium hydroxide produced is equal to 0.0139 moles.

A neutralization reaction can be defined as a chemical reaction in which an acid and base react with each other to prepare salt and water.

When HCl reacts with NaOH and the resulting salt is sodium chloride and water.

HCl    +  NaOH   [tex]\longrightarrow[/tex]   NaCl   +   H₂O

The chemical reaction, chemical reaction of sodium metal and water gives hydrogen gas and sodium hydroxide:

[tex]2Na+ 2H_2O \longrightarrow 2NaOH + H_2[/tex]

Given the amount of sodium metal = 0.32 g

The moles of sodium metal = 0.32/23 = 0.0139 moles

If the 2 moles of sodium produce sodium hydroxide = 2 mol

The 0.0139 moles of sodium will produce NaOH = 0.0139

Therefore, 0.0139 moles of HCl is required to neutralize 0.0139 moles of NaOH.
