Answer:

54.5% is the correct answer

Nataly_w [17]3 years ago
6 0

Answer: The percent composition of oxygen is 54.5%

Explanation:

Below I have attached my work through, but essentially the percent composition relies on finding the mass of the oxygens and dividing it by the mass of the whole compound. The masses of the elements can be found on the periodic table and added together to get a mass of the whole compound- ascorbic acid. Then, you turn this proportion into a percent by multiplying by 100%.

A student observes that water in a pot on a burner becomes hotter explain how energy is conserved in the situation
Daniel [21]

  • The water in the pot becomes hotter as a result of heat transfer.

  • <em>Energy can be transferred from a region to another , but there will still the same overall amount of energy</em> ( energy conservation)

  • When a pot containing water  is  placed on the stove and  heat is applied with the burner, there is a flow of heat from the burner to the water.

  • Heat will be transferred from the burner to the pot, then there will be transferred of heat from the pot to the water, the molecules there in the water  will be energized as a result of the heat transfer until the boiling point  is  reached.

  • Energy transfer can take place in three form, this could be conduction, radiation or convention.

  • Convention which is a cyclical process is the one that occurs in fluids only so as a result of convection , the water at the bottom will be heated and the molecules start moving and it will rise till it get to the water at the top of the pot.

<em>Therefore, the water is heated as a result of heat transfer.</em>

What is metallic bonding , properties and everything about it?
Elodia [21]
Metallic bonding

The particles in a metal are held together by metallic bonds.

High melting and boiling points

Metallic bonds are strong and a lot of energy is needed to break them. This is why metals have high melting points and boiling points.

Conducting electricity

Metals contain electrons that are free to move in the metal structure, carrying charge from place to place and allowing metals to conduct electricity well.

Metallic bonding - Higher tier

Metallic bonding is the strong attraction between closely packed positive metal ions and a 'sea' of delocalised electrons.
