Answer:
Answer to the question:
Explanation:
Differences between ionic bond and covalent bond:
The ionic bond occurs between two different atoms (metallic and non-metallic), while the covalent bond occurs between two equal atoms (non-metallic).
In the covalent bond there is an electron compartment, while in the ionic bond there is an electron transfer.
Ionic bonds have a high melting and boiling point, while covalent bonds usually have a low point.
A. To show how precise your measurements were
Explanation:
It is important to use the correct number of significant digits when reporting the results of an experiment because they show how precise measurement are.
- Precision is the ability to reproduce a particular set of results in an experiment.
- Every instrument have their precision level.
- The precision levels shows to what extent the values obtained can be trusted..
- Significant figures are not only important in recording measurements, they are also needed for calculations in science.

Explanation:
Energy loss through walls can be reduced using cavity wall insulation. This involves blowing insulating material into the gap between the brick and the inside wall, which reduces the loss by air circulating inside the cavity, therefore reducing loss by convection through the cavity.
Answer:
well the answers are 180 and 240 obviously
Explanation:
Answer:
It's weight would decrease over time.
Explanation:
The cold coke is going to stabilise in the room temperature. This causes the coke to heat up to room temperature. When the coke heats up, some molecules acquire enough kinetic energy that the evaporate. The evaporation of the molecules causes a decrease in weight.
Hope it helped!
