What part of the atom is responsible for the behavior of the alpha particles?

Answers

Answer 1

Answer:

Answer:

nucleus

Alpha particles are subatomic fragments consisting of two neutrons and two protons. Alpha radiation occurs when the nucleus of an atom becomes unstable (the ratio of neutrons to protons is too low) and alpha particles are emitted to restore balance.

Which statement must be true about a chemical system at equilibrium?(1) The forward and reverse reactions stop.
(2) The concentration of reactants and products are equal.
(3) The rate of the forward reaction is equal to the rate of the reverse reaction.
(4) The number of moles of reactants is equal to the number of moles of product.

Answers

(1) is wrong because at equilibrium both the reactant and the product are still being created they are just being created at the same rate meaning that

(3) is the answer. As the concentrations do not change, but the solution/system is still in dynamic equilibrium.

I agree with the answer below (partial credit would go to her/him I guess)
My answer I guess is more visual to explain
1 says --> | <--
2 is assuming because not all chemical system are the same although this could be true in some cases

What is the total number of moles of atoms in Pb(C2H3O2)2?

Answers

The total number of moles of atoms in Pb(C₂H₃O₂)₂ is 66.242 x 10²³ atoms.

What is mole?

The total number of moles of atoms, use Avogadro's number, which is approximately 6.022 x 10²³ particles (atoms or molecules) per mole.

The molecular formula of Pb(C₂H₃O₂)₂ has one lead (Pb) atom, two carbon (C) atoms, four hydrogen (H) atoms, and four oxygen (O) atoms in one molecule of the compound.

So, the total number of moles of atoms in one mole of Pb(C₂H₃O₂)₂ can be calculated as follows:

1 Pb atom x (1 mole Pb / 1 mole Pb(C₂H₃O₂)₂ x (6.022 x 10²³ atoms / 1 mole Pb) = 6.022 x 10²³ Pb atoms

2 C atoms x (1 mole C / 1 molePb(C₂H₃O₂)₂ x (6.022 x 10²³ atoms / 1 mole C) = 12.044 x 10²³ C atoms

4 H atoms x (1 mole H / 1 mole Pb(C₂H₃O₂)₂ x (6.022 x 10²³ atoms / 1 mole H) = 24.088 x 10²³ H atoms

4 O atoms x (1 mole O / 1 mole Pb(C₂H₃O₂)₂ x (6.022 x 10²³ atoms / 1 mole O) = 24.088 x 1023 O atoms.

6.022 x 10²³ Pb atoms + 12.044 x 10² C atoms + 24.088 x 10²³ H atoms + 24.088 x 10²³ O atoms = 66.242 x 10²³ atoms

Therefore, there are approximately 66.242 x 10²³ atoms in one mole of Pb(C₂H₃O₂)₂.

Farmer brown is planting crops in his feild s. He wants to prevent the topsoil from being blown away by the wind or washed away from by water. Which of these steps should he take. A: plow the soil many times. B: plant crops close together. C: water crops often to wet soil. D: leave the land free of crops for a long time

Answers

Hey!

I would say the answer is A. Plow the soil many times to lessen the chance of the topsoil being blown away.

Hope this helps !

Answer:

C: water crops often to wet soil.

Explanation:

Working in the plan industry, it becomes obvious that when watering the plants often, it will pack down the topsoil into the plant. Topsoil is lose at first as stated above, but when enough water gets on it, it becomes almost like mud. This is the kind of topsoil you want. No wind or water will mess it up because it already it watered! It will also help the grow. In addition, plowing is not correct because you only need to plow twice in the plant process. Before you plant the seeds, and to harvest the crops. If you plow to soon and often, you won’t have any plants.
