Water (2190 g ) is heated until it just begins to boil. If the water absorbs 5.75×105 J of heat in the process, what was the initial temperature of the water?

Answers

Answer:

37.18°C.

Explanation:

  • The amount of heat absorbed by water = Q = m.c.ΔT.

where, Q is amount of heat absorbed by water (Q = 5.75 x 10⁵ J).

m is the mass of water (m = 2190 g).

c is the specific heat capacity of liquid water = 4.18 J/g°C.

ΔT is the temperature difference = (final T - initial T = 100.0°C - initial T).

∴ Q = m.c.ΔT = 5.75 x 10⁵ J.

5.75 x 10⁵ J = (2190 g)(4.18 J/g°C)(100.0°C - initial T)

∴ (100.0°C - initial T) = (5.75 x 10⁵ J)/(2190 g)(4.18 J/g°C) = 62.81°C.

∴ initial T = (100.0°C - 62.81°C) = 37.18°C.

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.

How are revolution and year related

Answers

Revolution means orbiting around another body. 
A year is a time for a planet to complete one orbit around the Sun.

Explanation:
The words revolution and year are connected as a result of a revolution. The definition of a revolution is that the movement of 1 object around a middle or an in a very given length of your time which may be measured in terms of years. and year may be a peroid or length of twelve month within which the eart revovle round the sun.
