Answer:
The Etna volcano when it previously erupted released a lot of smoke, and then volcanic lava.
Explanation:
The eruption of this volcano was on the Italian island of Sicily.
Where there were large columns of smoke and after that the volcanic magma in a viscoelastic state was released into the external environment.
Some sources claim that the eruption of this volcano reached the areas of Zaffanera.
Answer:
- Deep red fire is about 600-800° Celsius
- Answer: {1102.91}
Given: K= °C + 273.15
K = 1,376.06
Since you’re trying to find C (Celsius) you want to get C by itself in the problem. So you subtract 273.15 from that side. Anything you do to one side of the equal sign you have to do to the other side, so also subtract 273.15 from K (1,376.06).
1,376.06 - 273.15 = {1102.91°C}
Answer: A) polar molecule
Explanation: Polar molecules are molecules which contain atoms of different electronegativities.
Non polar molecules are molecules which contains atoms of same electronegativities.
Water is a polar covalent molecule formed by unequal sharing of electrons. Oxygen being more electronegative tend to keep the electron pair towards itself thus generating a partial negative charge. The hydrogen acquire a partial positive charge thus resulting in a polar molecule.
The bent shape is due to repulsion between lone pairs and bond pairs of electrons.
Reactivity. It is the ability of matter to combine chemically with other substances.
