Answer:
The atomic mass of the other isotope = 106.905 amu
Explanation:
Step 1: Data given
Atomic mass of silver = 107.868 amu
Ag109 isotope has an atomic mass of 108.905 amu = 48.16 %
Step 2: Calculate the abundance of the other isotope
100.0 % - 48.6 % = 51.84 %
107.868 = 0.4816*108.905 + 0.5184*X
55.419352 = 0.5184X
X = 106.905
The atomic mass of the other isotope = 106.905 amu
Explanation:
H2So4=sulphuric acid , strong acid
<u>Answer</u>:
This describes primary succession.
<u>Explanation</u>:
In the case of primary succession, the sequence of communities is formed in lifeless habitat. With the formation of the new ecosystem, life evolves gradually. In retreating glacier’s case, the new land is being revealed on its receding.
During the initial stage, the land is void of soil and vegetation. This leads to micro-organisms to breakdown the bedrock and soil formation starts. With the efficient amount of soil creation the new vegetation starts.
Answer:
no ,its not necessary tht two objects have same volume have the same mass because the density of the material they are made up of can be different. mass and volume areindependent, two objects with thesame volume can have differentmasses. Therefore, the objects can have different densities.
Answer: Here are some examples
Explanation:
1. In the southern spring, ozone is destroyed above Antarctica, mainly by manufactured compounds called chlorofluorocarbons (CFCs )
2. It is now generally accepted that the loss of stratospheric ozone is caused by chemical reactions initiated by chlorofluorocarbons.
3. Your refrigerator and other home appliances emit Chlorofluorocarbons, or CFCs, as do aerosol spray cans.
Hope this hlps!
