Answer:
B. Ernest Rutherford
Explanation:
Ernest Rutherford was a renown Physicist and a Physics Nobel price winner. In 1911 he proposed the planetary model of atom. When the experiment were conducted he proposed that the atom had a charged nucleus and are surrounded by electrons. This finding was the basis for subsequent studies on radioactivity.
A mixture of 3.05-atm N₂(g) and 5.29-atm He(g) exerts a total pressure of 8.34 atm.
<h3>What does Dalton's law of partial pressure state?</h3>
Dalton's law states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.
A mixture of N₂(g) and He(g) exerts a total pressure of 8.34 atm, while the partial pressure of N₂ is 3.05 atm.
We will use Dalton's law to calculate the partial pressure of He.
P = pHe + pN₂
pHe = P - pHe = 8.34 atm - 3.05 atm = 5.29 atm
where,
- P is the total pressure.
- pHe is the partial pressure of He.
- pN₂ is the partial pressure of N₂.
A mixture of 3.05-atm N₂(g) and 5.29-atm He(g) exerts a total pressure of 8.34 atm.

The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.
Answer:
C.
Explanation: In nuclear fission and fusion reactions, some of the energy in matter is converted to energy. If you weigh the reactants and the products, the products will weigh less than the reactants. This is called the mass defect and is the result of turning matter into energy.
