Which of the following statements explains why atoms are always neutral in charge
laila [671]

Answer:

D. They have the same number of protons as electrons.

Explanation:

Protons are found in the nucleus of the atom and have a positive charge while electrons orbit around the nucleus and have a negative charge. Usually, in a neutral atom of an element, the number of protons is equal to the number of electrons. This is why the atom has no charge because the positive and negative charges cancel out. When an atom loses an electron its charge turns positive while when it gains an electron its charge turns negative.

Calculate the heat released when 25.0 grams of water freezes at 0 degree Celsius.
mafiozo [28]

Answer:

= 8350 joules

Solution and explanation:

  • The heat of fusion refers to the quantity of heat released when a given amount of water freezes.
  • For example, 1 g of water releases 334 J when it freezes at 0°C.

Therefore; For 25.0 g of water.

Heat released = Mass of water × heat of fusion

                        = 25 g × 334 J/g

                        = 8350 Joules

Hence, the amount of heat released when 25.0 g of water freezes at 0°C is 8350 J.

Compare and contrast chemical potential energy and elastic potential energy
nikdorinn [45]
Chemical Potential Energy is released when chemical bonds between atoms are broken (like covalent and ionic) and is released mainly as thermal
Elastic Potential is released when the molecules in the material are allowed to go back to there original form, and is released mainly as kinetic
