Answer:
3
Explanation:
On the left side we have 3 Calcium atoms and 6 fluorine atoms
that means there need to be the same number on the right side
in the CaF2 molecules we already have 2 fluorine atoms so by multiplying with 3 we get 3 Ca and 6F
Radioactive decay is a pseudo-first order reaction. When you know the half-life of the material, you could use this equation.
A= A₀(1/2)^t/h
where
A is the final activity
A₀ is the initial activity
t is the time
h is the half-life
A = (0.64)(1/2)^88/44 = <em>0.16 mbq</em>
Answer:
The balanced equation would be
2Na(s) + 2H2O(l) ===> 2NaOH(aq) + H2(g)
where
s---solid
l--- liquid
aq--- aqueous
g---- gas
Are the states of each substance
Explanation:
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
