1 Hydrogen 1s1
2 Helium 1s2
3 Lithium 2s1
It shows the atomic number
1 - causes the molecules of the object or surface it strikes to vibrate faster, increasing its temperature.
2-carbon dioxide, methane, nitrous oxide, and water vapor it has to be one of these 3
3-The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.”
4- because of the fossil fuels that people are burning for energy.
5- due to human activities
Answer:
a)there would be no reaction
Explanation:
The activity series of metals has many functions. The one applicable to this problem is that it can be used to determine whether a reaction will occur or not. Also, based on the positions of metals in the series, we can know how reactive a metal is compared to another.
In a single displacement reaction, a metal replaces another metal based on their position on the activity series. Metals that are higher in the series are generally more reactive than others below them and so will displace them.
Would aluminum replace magnesium to form a new compound or would there be no reaction?
Magnesium is higher than aluminum in the activity series. Therefore it is more reactive than aluminum. No reaction will occur.
Answer:
Double bonds. It says I have to write more words lol but yeah it's double bonds
