A is sodium D is aluminum
<span> </span><span>Fusion
reaction is a type of nuclear reaction where two or more nuclei combine or
collide to form an element with a higher atomic number. This happens when the
collision is in a very high speed. In this process, some of the matter of the
fusing nuclei is converted to energy.</span>
Answer:
studies
Explanation:
if they get plenty of studies then they get it
V = 75 mL = 0,075 L = 0,075 dm³
C = 2.1M
n = ?
---------------
C = n/V
n = C×V
n = 2.1×0,075
n = 0,1575 mol
--------
mKCl: 39+35.5 = 74,5 g/mol
74,5g --------- 1 mol
Xg ------------- 0,1575 mol
X = 74,5×0,1575
X = 11,73375g KCl
:•)
The valence of helium is 0.
