Which type of nuclear energy involves splitting atoms

1 answer:

7 0

That would be nuclear fission. This occurs at a rapid level in the Atom Bomb. That is a chain reaction causing an explosion whereas the nuclear fission that occurs in a nuclear reactor is controlled.

When a 1.06 g sample of Compound Q, a nonelectrolyte, is dissolved in 11.6 g of water, the boiling point of the resulting soluti

Vesna [10]

Answer:

The molar mass of compound Q is 100 g/mol

Explanation:

Step 1: Data given

Mass of compound Q = 1.06 grams

Mass of water = 11.6 grams

Boiling point of the solution = 100.47 °C

Boiling point of water = 100.00 °C

Kb for water = 0.512 °C/m

Step 2: Calculate molality

ΔT = i*kb*m

⇒ with ΔT = the boiling point elevation = 0.47 °C

⇒ with i = the van't Hoff factor = 1

⇒ with kb = the boiling point elevation constant = 0.512 °C/m

⇒ with m = the molality = moles compound Q / mass water

m = ΔT / (i*Kb)

m = 0.47 / 0.512

m = 0.918 molal

Step 3: Calculate moles of Q

Molality = moles Q / mass H2O

moles Q = 0.918 molal * 0.0116 kg

moles Q = 0.0106 moles

Step 4: Calculate molar mass

Molar mass Q = mass Q / moles Q

Molar mass Q = 1.06 grams / 0.0106 moles

Molar mass Q = 100 g/mol

The molar mass of compound Q is 100 g/mol

1.What one factor identifies an atom as a specific element? . . Choices: the number of protons. . the atomic mass. . the number

Mnenie [13.5K]

Question 1. What one factor identifies an atom as a specific element? Answer: the number of protons. Remember that the atoms of a same element have the same number of protons, and the atoms of different elements cannot have the same number of protons. That permits to order the elements according to the atomic number (number of protons) in the periodic table. Question 2.An atom of fluorine has an atomic number of 9 and an atomic mass of 19. The atom contains Answer: 9 protons, 9 electrons, and 10 neutrons : because the atomic number is the number of protons, the number of electrons must be equal to the number of protons (because the atom is neutral), and the mass number is the number or protons plus the number of neutrons: 9 protons + 10 neutrons = 19 mass number (atomic mass). Question 33.Experiments with cathode ray tubes led to a new model of the atom, sometimes called the \"plum pudding\" model, because of the discovery of the <span>. Answer. electron ... when electron was discovered JJ Thompson proposed the plum pudding model, in which the atom was a solid positively charged sphere with electrons distributed inside it.</span>

Use the reaction 2NO 2 (g) = N 2 O 4 (g) to answer the following question:

anyanavicka [17]

Answer:

According to Le Chatelier’s Principle, a stress placed on a system at equilibrium will cause the equilibrium to shift to counteract the stress. For example, a temperature increase in the above reaction will favor the reverse reaction to use the excess heat and form brown NO2 gas. A temperature decrease in the above reaction favors the forward reaction to produce heat and form colorless N2O4 gas.

Classifying Reactions

Marysya12 [62]

Part I4Fe + 3O2 -> 2Fe2O3. This is redox reaction and the reaction is also called rusting. The reaction can be classified as a combination reaction.
Part II2H2O2 -> 2H2O + O2. The evolution of bubbles was the indication that a chemical reaction was taking place.
Part III.2Zn + 2HCl -> H2 + ZnCl2. A displacement reaction occurs in the reaction. A metal and a acid are common reactants in this reaction.
Part IV.NaHCO3 + CH3COOH -> CH3COONa + H2CO3
The second reaction isH2CO3 -> CO2 + H2O
which is decomposition reaction.
