Answer:
34.5 g F2. 1 mol F2. 1 mol Br2. 159.808 g Br2. = 145 g Br2. 38 g F2. 1 mol F2. 1 mol Br2 ... a) How many grams of oxygen are necessary to react completely with 33 ... hydrogen to ammonia would require how many atoms of nitrogen gas? N2.
Explanation:
The exception to an octet of electrons would be the first noble gas, Helium, which only has two valence electrons. This primary affects the element hydrogen, which forms stable compounds by achieving two valence electrons.
It is c because there are many decades today.
Electronic configuration is given by
- 1s orbital is filled
- 2s orbital is unfilled
So
<span>According to Le Chatelier's Principle, the position of
equilibrium moves to counteract the change, the position of equilibrium
will move so that the concentration of
products of chemical reaction increase, if:</span>
<span>1) increase temperature, because this endothermic reaction.</span>
<span>2) increase concentration of reactant.</span>
<span>3) decrease pressure of the system, so reaction moves to direction where is more molecules.</span>
