In decomposition, two or more reactant combine to form one product only.
Answer:
argon has no tendency to gain nor lose electrons.
Explanation: it's a noble gas
Explanation:
First I'm going to draw the structure of the neutral calcium atom and the structure of the chlorine atom.
Now I'm going to draw only the valence shells of ions that participate in ionic bonding:
So Ca2+ will donate 2 electrons for both 2 atoms of Chlorine, forming CaCl2.
The chemical composition of the magma and the rate at which it cools determine what rock forms. Igneous rocks can cool slowly beneath the surface or rapidly at the surface. These rocks are identified by their composition and texture.
Hope this help XD
Answer: 1.0 mol/dm3
Explanation:
Given that:
Amount of moles = 0.25 moles
Volume = 250 millliters of solution
Convert milliliters to liters
If 1000 milliliters = 1 liter
250 milliliters = (250/1000) = 0.25 L
Recall that 1 liter = 1dm3
so, 0.25 liters = 0.25 dm3
Now, molarity is calculated by dividing the amount of a substance by the volume of the solution.
i.e Molarity = (Amount in moles/volume in dm3)
Molarity = (0.25 moles / 0.25 dm3)
= 1.0 mol/dm3
Thus, the molarity of the solution is 1.0 mol/dm3
