False. Electromagnetic and Gravitational forces can overcome .
Natali5045456 [20]3 years ago

Answer:

True

Explanation:

The strong nuclear force is at times more rapidly than the electromagnetic force (EM). In essence, this can be given by the relationship:

\frac{1}{r^{-7} } instead of \frac{1}{r^{-2} }

Therefore, the strong proton – proton repulsion between two atoms with smaller radii is able to overcome to overcome non-charge forces, in this case, the gravitational and electromagnetic forces.

Protons and neutron exist of quarks. It requires a strong magnetic force to overcome the strong residual repulsion between two protons.

In a reaction between 6.0 g of oxygen gas, 4.0 g of hydrogen gas, and 5.0 g of solid sulfur at standard temperature and pressure
nikitadnepr [17]

Answer:

The limiting reagent is the O₂

Explanation:

We can think, this reaction

2O₂(g) + H₂(g) + S(s)  →  H₂SO₄

Mole of each = Mass / molar mass

6 g / 32 g/m = 0.187 mole O₂

4g / 2 g/m = 2 mole H₂

5g / 32.06 g/m = 0.156 mole S

Ratio between reactants is 2:1:1, 1:2:1, 1:1:2

For 2 mole of O₂, I need to react 1 mol of H₂ and 1 mol of S

0.187 mole of O₂, I need (the half)

0.093 mole of H₂ and 0.093 mole of S

For 1 mole of H₂, I need to react 2 mole of O₂ and 1 mol of S

2 mole of H₂, I need (the double of O₂ and the same for S)

4 mole of O₂ ; 2 mole of S

For 1 mol of S, I need to react 1 mol of H₂ and 2 mole of O₂

0.156 mole I need the same amount for H₂ and the double for O₂

0.156 mole of H₂ and 0.312 mole of O₂

In both cases, I can't make react, all the mass of oxygen, so this is the limiting reagent.

G brønsted-lowry proton transfer reaction, hydroxide functions as a/an ______.
Katen [24]

In a bronsted lowry proton transfer reaction, the hydroxide functions as a/an <u>proton acceptor.</u>

Bases are the opposite of acids. Bases are basic since they take or accept protons. For example, a Hydroxide ion can accept a proton to form water.
