Which of the following shows a valid combustion reaction?

2Al + 2O2 → 2AlO + O2
C2H4 + 3O2 → 2CO2 + 2H2O
2CH4 + O2 → 2CO + 4H2
Ca + O2 → CaOH

Answers

Answer:   C2H4 + 3O2 → 2CO2 + 2H2O

Explanation:

2Al + 2O2 → 2AlO + O2            Not Balanced Properly:  2Al + O2 = 2AlO  

C2H4 + 3O2 → 2CO2 + 2H2O  Looks Good

2CH4 + O2 → 2CO + 4H2          Not Correct:  CO should be CO2

Ca + O2 → CaOH                        Not Balanced and No source for the H

Answer:

2H4+3O2 →2CO2+2H2

When a gas is collected over water, the partial pressure of water must be subtracted from the total pressure. If the total pressure was 761 mmHg and the pressure for water is 17.2 torr, what is the pressure due to the gas collected

Answers

Answer is: the partial pressure of the hydrogen 500 mmHg.

p(total) = 523.8 mmHg.

p(water) = 23.8 mmHg.

p(total) = m(water) + p(hydrogen).

p(hydrogen) = p(total) - p(water)..

p(hydrogen) = 523.8 mmHg - 23.8 mmHg.

p(hydrogen) = 500 mmHg.

mmHg or millimeter of mercury is a manometric unit of pressure.

A 2.37 g sample of a substance suspected of being pure gold is warmed to 71.8 ∘C and submerged into 15.9 g of water initially at 24.3 ∘C. The final temperature of the mixture is 27.0 ∘C.

Answers

Answer:

specific heat capacity of the unknown is 629.66 J/kg C

Explanation:

As we know that gold is heated to 72.3 degree C and mixed with water at 24.8 degree C

Now the final temperature of the mixture is 26 degree C

here we can say that heat given by the gold = heat absorbed by the water

So we will have

Q_{in} = Q_{out}Q

in

=Q

out

2.62 s (72.3 - 24.8) = 15.6 (4186) (26 - 24.8)2.62s(72.3−24.8)=15.6(4186)(26−24.8)

so we will have

s = 629.66 J/kg Cs=629.66J/kgC

so specific heat capacity of the unknown is 629.66 J/kg C

What is covalent bond?

Covalent bond is defined as a type of bond which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.

Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.

Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.

The energy released by a nuclear fusion reaction is produced when
1. energy is converted to mass
2. mass is converted to energy
3. heat is converted to temperature
4. temperature is converted to heat

Answers

Answer:

2

Explanation:

energy produced in nuclear fusion or even fission is due to mass defect and it can be calculated by Einstein equation e=mc2

The statement, that describes energy released by a nuclear fusion reaction is produced is "mass is converted to energy."

What is nuclear fusion?

Nuclear fusion is the process by which two light atomic nuclei merge to produce a single heavier one, releasing huge quantities of energy in the process.

A fusion reaction occurs when two light nuclei combine to form a single heavy nucleus. Because the overall mass of the resulting single nucleus is smaller than the mass of the two initial nuclei, the process releases energy.

That is, nuclear energy refers to the energy released as a result of mass loss during the nuclear fusion processes. Both of these processes transform mass loss into energy in accordance with Einstein's mass-energy ratio, E = [tex]mc^{2}[/tex]. As a result of the fusion reaction, mass is destroyed and energy is released.

Hence, the correct answer is 2.

Answers

Answer: There are 36 valence electrons.

Explanation:

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the valence electrons of C₄H₈O₂ is 32.

What is element?

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

A valence electron is a negatively charged particle, located in the outermost shell of an atom, that can be transferred to or shared with another atom. To calculate total valence electrons in C₄H₈O₂, we need to add the individual valence electrons of each element.

Valence electrons of C₄H₈O₂= {valence electrons of C×4}+{valence electrons of H×4}+{valence electrons of O×2}

Valence electrons of C₄H₈O₂= {4×4}+{1×4}+{6×2}

Valence electrons of C₄H₈O₂=32

Therefore, the valence electrons of C₄H₈O₂ is 32.
