Answer: Climate change increases carbon in our atmosphere affecting the water. 97% of earth is ocean so the cO goes into the water creating the acidification. killing coral and plankton
Answer : The mass of Ni is, 80.346 g
Solution :
First we have to calculate the number of moles.
Now we have to calculate the number of atoms of 
As 1 moles contains 
number of molecules
So, 1.369 moles contains 
number of molecules
One molecule has one nitrogen atom then number of molecules of will contain number of nitrogen atoms
As per question number of Ni atoms is equal to the number of nitrogen atoms
Number of Ni atoms= atoms
Number of moles = 
Mass of Nickel = 
Molecular mass of Nickel = 58.69 g/mol
Mass of nickel = 
Answer:
Vegetation plays an important role in the water cycle by preventing soil erosion and increasing groundwater levels. Green plants also release water vapor in the air as a by-product of photosynthesis, thus involving groundwater in the water cycle.
Explanation:
Because H2O molecules make Hydrogen bounding and that's the first and strongest bound between molecules of a structure... So they stick together and don't let each other get evaporated...
U need lotsa energy to turn them into Gas shape
Answer:
Modern periodic law
Explanation:
There are many ways of stating the modern periodic law. Generally, the modern periodic law states that the properties of elements are a periodic function of their atomic numbers. That means, similar properties recur periodically when elements are arranged according to increasing atomic number.
Two scientists were largely responsible for our present day understanding of the modern periodic law, they are, Mendeleev and Moseley. Their work laid the foundation for the periodic table in its current form.
