Why is methanol written as ch3oh instead of ch4o?​

Answers

Answer 1

Answer: Here comes the role of another formula, which we refer to as the structural formula and that is CH3OH for methanol. The structural formula gives us an additional information that carbon is attached to three hydrogen atoms and one oxygen atom.

3. Two liquids are being studied to find which one
evaporates more quickly. Liquid A boils at 50°C and
Liquid B boils at 25°C. Which liquid do you think
evaporates faster?
A.Liquid A
B.Liquid B
C.Both will evaporate at the same rate
D.Neither evaporate at all

Answers

Answer: D

Explanation:

Because at temerature at 25 and 50 is

to low for a compound to evaporate as gas because the bioling point is 100.

Answer: B

Explanation: Evaporation rate is influenced by the liquid's boiling temperature. A lower boilng point means that converting the liquid to a gas takes less energy because higher temperatures mean higher energy content. Assuming that this relationship holds at room temperature and that all other factors are equal, you should expect that Liquid B will evaporate faster.

El acido nitrico se obtiene industrialmente por oxidacion de amoniaco (nh3), de acuerdo con la ecuacion: 4nh3 + 702 - h2o + hno2 + 2hno3 ¿ cuanto acido nitrico del 90% de pureza se podra obtener a partir de 1.36 kg de amoniaco?

Answers

Answer:

2800 g de ácido nítrico

Explanation:

La ecuación por la oxidación de amoniaco es:

4NH₃  +  7O₂  →  4H₂O  +  2HNO₂  +  2HNO₃

Si pensamos que el oxígeno es el reactivo limitante, trabajamos con el amoniaco. Convertimos su masa a moles:

1.36 kg = 1360 g

1360 g . 1mol  /17g = 80 moles

Si 4 moles de amoniaco pueden producir 2 moles de acido nítrico

80 moles producirán, (80 . 2)/4 = 40 moles.

Convertimos los moles a gramos:

40 mol . 63g /mol = 2520 g

Si le aplicamos la pureza

2520 g . 100/90 = 2800 g

[tex]{\rm 1\; C_3H_8} + {\rm 5\; O_2} \to {3\; \rm CO_2} + {4\; \rm H_2O}[/tex].

Explanation:

[tex]{\rm ?\; C_3H_8} + {\rm ?\; O_2} \to {?\; \rm CO_2} + {?\; \rm H_2O}[/tex].

Among the four species in this reaction, [tex]\rm C_3H_8[/tex] is species with the largest number of atoms per molecule. Assume that the coefficient of this compound is [tex]1[/tex].

[tex]{\rm 1\; C_3H_8} + {\rm ?\; O_2} \to {?\; \rm CO_2} + {?\; \rm H_2O}[/tex].

By the conservation of atoms, the number of atoms on the right-hand side of the reaction should match those on the left-hand side. In this reaction, [tex]\rm CO_2[/tex] is the only product with carbon atoms, whereas [tex]\rm H_2O[/tex] is the only product with hydrogen atoms. These [tex]3[/tex] carbon atoms and [tex]8[/tex] hydrogen atoms would correspond to:

[tex]3 / 1 = 3[/tex] [tex]\rm CO_2[/tex] molecules, and[tex]8 / 2 = 4[/tex] [tex]\rm H_2O[/tex] molecules.

It takes 2 g of chlorine to sanitize 1,000,000g of water. How much chlorine will it take to sanitize a 40,000-gallon pool? ( 1 gallon =3.7L; the density of water is 1.0g/ml ) Show your work

Answers

Answer:

0.1g (Gallon) of chlorine

Explanation:

Formula

1 gallon = 3.7L; the density of water is 1.0g/ml

Given

2g (gallon) of chlorine to sanitize = 1,000,000g (gallon) of water

Solve

If 2g (gallon) chlorine = 1,000,000g (gallon)

∴, ? chlorine = 40,000

The First step; set up an equation

1000000/2 = 40000/?

The Next step; divide 1 million to 2

1000000 ÷ 2 = 500000

Then, divide the result by 40000

40000 ÷ 500000 = 0.08

In the nearest unit that is 0.1

Therefore, it will take 0.1g (gallon) of chlorine to sanitize a 40,000-gallon pool.

Answer:

296

Explanation:

1 gallon = 3.7 L

40,000 gallon

= 40,000 × 3.7

= 148,000 L

1 g = 1 / 1000 L

1,000,000 g

= 1,000,000 / 1000

= 1,000 L

Let x be the amount of chlorine that will it take to sanitize a 40,000-gallon pool.

2 : 1,000 : : x : 148,000

2 / 1,000 = x / 148,000

x × 1,000 = 2 × 148,000

x = ( 2 × 148,000 ) / 1,000

= 2 × 148

x = 296 g

Therefore,

296 g of chlorine will it take to sanitize a 40,000-gallon pool.

What is the total number of grams of HI in 0.500 liter of
1.00 M HI?
64.0 g
128 g
1.00 g
0.500 g

Answers

Answer:

The amount of HI is "64 grams".

Explanation:

The given values are:

Volume,

= 0.500 L

Molarity,

= 1.00 H

Molar mass of HI,

= 128

Now,

The moles of HI will be:

=  [tex]Molarity\times Volume[/tex]

On substituting the values, we get

=  [tex]1.00\times 0.500[/tex]

=  [tex]0.5 \ mol[/tex]

hence,

The amount of HI will be:

=  [tex]Moles\times Molar \ mass[/tex]

=  [tex]0.5\times 128[/tex]

=  [tex]64 \ grams[/tex]

The heat of vaporization of a liquid is 84.0 J/g. How many joules of heat would it take to completely vaporize 172 g of this liquid at its boiling point?

Answers

Answer:

14,448 J of heat would it take to completely vaporize 172 g of this liquid at its boiling point.

Explanation:

The heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to Q = m*L, where L is called the latent heat of the substance and depends on the type of phase change.

During the evaporation process, a substance goes from a liquid to a gaseous state and needs to absorb a certain amount of heat from its immediate surroundings, which results in its cooling. The heat absorbed is called the heat of vaporization.

So, it is called "heat of vaporization", the energy required to change 1 gram of substance from a liquid state to a gaseous state at the boiling point.

In this case, being:

Q=?m= 172 gL= 84 [tex]\frac{J}{g}[/tex]

and replacing in the expression Q = m*L you get:

Q=172 g*84 [tex]\frac{J}{g}[/tex]

Q=14,448 J

14,448 J of heat would it take to completely vaporize 172 g of this liquid at its boiling point.

Chemical reactions follow the law of conservation of mass. This is seen on paper as a balanced equation. Explain the law of conservation of mass and how to balance an equation.

Answers

The law of conservation of mass states that. “The mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another”. According to the law of conservation of mass, the mass of the reactants must be equal to the mass of the products for a low energy thermodynamic process.

I’m pretty sure that when balancing a chemical equation no one is thinking about the conservation of mass. It’s all about counting atoms. When you have the same number of each kind of atom on either side of the arrow, then the equation is balanced. Now, that’s not to dismiss the law of conservation of mass which is verified upon closer inspection of the balanced equation.

eg CH4 + O2 → CO2 + H2O - needs balancing.

you use the idea that each type of atoim is conserved - so looking at this you can see it is not currently correct. On the LHS there are 2 O atoms and on the RHS there are 3 O atoms- the number of atoms must remain unchanged. We dont bother about their mass ( although mass is conserved)’
