Option D )CH3COOH + 202 - 2CO2 + 2H20
4
is a combustion reaction ...but I'm not sure if its for an inorganic substance.
10^8 just makes it easier to write out big numbers. It makes it so you don't have to keep writing out the really long number over and over.
If you were wondering.
3.0 * 10^8=300,000,000.0
Answer:
В. No, because the mass of the reactants is less than the mass of the products.
Explanation:
Chemical equation:
NaBr + Cl₂ → 2NaCl + Br₂
The given equation is not balanced because number of moles of sodium and bromine atoms are less on reactant side while more on the product side.
There are one mole of sodium and one mole of bromine atom on left side of equation while on right side there are 2 moles of bromine and 2 moles of sodium atom are present. The number of moles of chlorine atoms are balanced.
Balanced chemical equation:
2NaBr + Cl₂ → 2NaCl + Br₂
Now equation is balanced. Number of moles of sodium , chlorine and bromine atoms are equal on both side.
Answer:180°
Explanation:
According to VSEPR theory, if the valence shell of the ceteral atom in a molecule contains only two valence electron pairs, the valence electron pairs will arrange themselves along a straight line, forming a bond angle of 180°
