Answer: Option (d) is the correct answer.

Explanation:

In combustion reaction, a compound reacts with oxygen and results in the formation of carbondioxide and water.

For example, when propane reacts with oxygen it results in the formation of carbondioxide and water.

The reaction is as follows.

      C_{3}H_{8} + O_{2} \rightarrow CO_{2} + H_{2}O

Also, when there is incomplete combustion of carbon then it results in the formation of carbon monoxide. This reaction is as follows.

         C + \frac{1}{2}O_{2} \rightarrow CO

Thus, we can conclude that the products of a combustion reaction do NOT include hydrogen.

ICE Princess25 [194]

Answer:

42,3g of H₂O

Explanation:

For the reaction:

4NH₃(g) + 5O₂(g) ⟶ 4NO(g) + 6H₂O(g)

62,8 g of NH₃ are:

62,8g×(1mol/17,031g) = <em>3,69 moles of NH₃</em>

62,8 g of O₂ are:

62,8g×(1mol/32g) =<em> 1,96 moles of O₂</em>

For a complete reaction of 1,96 moles of O₂ you need:

1,96mol O₂×(4mol NH₃ / 5molO₂) = 1,57 moles NH₃. As you have 3,69 moles, limiting reactant is O₂.

Assuming a complete reaction, 1,96mol O₂ produce:

1,96mol O₂×(6mol H₂O / 5molO₂) = 2,35 moles of H₂O. In grams:

2,35 moles of H₂O×(18,01g/1mol) = <em>42,3g of H₂O</em>

I hope it helps!

Which statement about schrodingers theory of the atomic model is true?
Svetach [21]

I found the complete question:

Which statement about schrodingers theory of the atomic model is true?

A. it proved that the nucleus of an atom is positively charged.

B. it was the first theory to discuss the existence of electrons.

C. it explained the odds of finding the position of an electron.

D. it assumed the electron cloud to be heavier than the nucleus.

Answer:

C. it explained the odds of finding the position of an electron.

Explanation:

Erwin Schrodinger formulated the wave equation of electrons. His wave equation highlighted the probability of where an electron can be found or located in an energy level.

The region of maximum probability of where an electron is located is referred to as an electron cloud or an orbital.

Please begging you guys someone help me
BaLLatris [955]

Answer:

See Explanation

Explanation:

10) From the options provided for this question, gamma particle is the most energetic. Recall that gamma rays are high energy electromagnetic radiation which are capable of causing a high degree of ionization in matter.

11) The bombardment of U-235 with neutrons leads to the reaction;

U\frac{235}{92}  + n\frac{1}{0}---> I\frac{138}{53}  + Y\frac{95}{39} +3n \frac{1}{0}

Hence

a = 92, b= 95, c= 53

12) In positron emission, a proton is transformed into a neutron. The mass number of the daughter nucleus is the same as its parent but the atomic number decreases by 1.

Hence;

Th\frac{231}{90} -----> e\frac{1}{0} +Ac \frac{231}{89}

An aluminum ion has a +3 charge. What change did the atom undergo to attain this charge?
lesya692 [45]
When an ion loses electrons, it becomes a positive ion even though it does not lose protons. If there are more protons than electrons in the ion, the ion will have a positive charge.
