Answer:

the first one is branched, the second one is also branched and the third one is cycloalkane

Answer:

A: straight chain, B: branched chain, and C: cycloalkane.

Explanation:

Based on the assumption that the reaction involves N and O to produce NO, if 25.0 g of NO are produced, the amount of N gas used would be 11.66 grams

From the equation of the reaction:

       N + O ---------> NO

Mole ratio of N to NO is 1:1

Mole of 25.0 g of NO = 25/30.01 = 0.833 moles

Equivalent mole of N = 0.833 moles

Mass of 0.833 moles N = 0.833 x 14 = 11.66 grams

Answer:

6.02 x 1023

Explanation:

Its numerical value is 6.02 x 10 (23). Therefore, a 12.01 g sample of carbon contains 6.02 x 10 (23) carbon atoms.

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.

Answer:

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=

=4.46534\sdot10^{-4}M;=4.46534⋅10−4M;

The positive difference in concentration of [[tex]H_3O^+[/tex]] is [tex]4.46534 X 10^{-4}M[/tex] when NaOH was added to a 7.75 x [tex]10^-3[/tex] M solution of HCl so that the end solution has a pH of 3.500.

It is the measure of how much of a given substance there is mixed with another substance.

pH=−log[[tex]H_3O^+[/tex]]

[[tex]H_3O^+[/tex]]=[tex]10^{-pH}[/tex]

[[tex]H_3O^+[/tex]]=[tex]10^-^p^H[/tex]

If pH=3.350

pH=3.350

[[tex]H_3O^+[/tex]]=[tex]10^{-3.35}[/tex]=[tex]4.467 X 10^{-4}M[/tex]

[[tex]H_3O^+[/tex]]=[tex]10^{-3.35}[/tex]

=[tex]4.467 X 10^{-4}M[/tex]

If pH=6.780

pH=6.780

[[tex]H_3O^+[/tex]]= [tex]10^{-6.78}[/tex]=[tex]1.66 X 10^{-7}M[/tex]

Hence, the positive difference in concentration of [[tex]H_3O^+[/tex]] is[tex]= 4.46534 X 10^{-4}M[/tex]

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.

For  a typical mammalian cell, the net transport by the sodium-potassium exchange pump, Work done is mathematically given as

W= 5.6*10-18 J

Generally, the equation for the Potential difference   is mathematically given as

Potential difference = Work done / Charge

Therefore

W=q*P.d

Q= 500 * 1.6*10-19 C

P.d. = 70 mV

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.

The new volume occupied by the sample of gas is 4.96L.

Given the data in the question;

Final Volume; [tex]V_2 = \ ?[/tex]

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]

Therefore, the new volume occupied by the sample of gas is 4.96L.

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
