Which statement describes one acid-base theory?(1) An acid is an H+ acceptor, and a base is an H+ donor.

(2) An acid is an H+ donor,. and a base is an H+ acceptor.

(3) An acid is an H- acceptor, and a base is an H-donor.

(4) An acid is an H- donor, and a base is an H­ acceptor.

Answers

The answer is an acid is an H+ donor and a base is a H+ acceptor. This is in accordance to the Lewis definition of acids, which states that an acid is any substance that is able to release H+ ions in a solution or one that is able to accept a pair of nonbonding electrons. Another example of an acid-base theory is the Bronsted-Lowry theory of acids and bases.

A 10-Newton object displaces 12 Newtons of water. Will this object sink of float?I'm confused, my guess is sink.

Answers

Answer: The object will float.

Explanation:

Balanced force is defined as the force that gets cancelled out when equal forces are acting in the opposite direction. The net force on the system comes out to be 0.

Unbalanced force is defined as the force that does not get cancelled out because unequal forces act on the system in opposite direction. The motion of the object is in the direction of net force.

According to the question:

Object is exerting a downward force of 10 N on the water and water is exerting an upward force of 12 N on water.

As, the upward force by water is more than the downward force by object. So, the object will float on the surface of water.

If the downward force by the object is been more than the upward force, the object will sink.

Hence, the object will float.
This object would float

In a model of Earth's layers that is determined by physical properties, how might the atmosphere be classified? Would it be part of the lithosphere or a seperate layer?

Answers

Generally, the Earth is divided into spheres which include the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). The earth is divided into three layers based on chemical composition and these are the core, mantle and crust. In addition, the earth is also divided into physical properties which include lithosphere, athenosphere, mesosphere, outer core and inner core. Based on the given details, we can conclude that the atmosphere cannot be part of the lithosphere but instead, it is classified in a separate layer. The lithosphere only consists the outermost, rigid part of the Earth, which are the crust and the mantle. Hope this answer helps.

What are the properties of the reactants?​

Answers

Answer:

Reactants starts the chemical reaction and gives right to the product either by thermal decomposition or in the presence of a catalyst.

Explanation:

Reactants and products contain the same atoms, but they are rearranged during the reaction, so reactants and products are different substances.

Answer:

The properties of reactant are:

1. it contains the same atoms

2. it describes the pathway of the reaction.
