Answer:
The equilibrium shifts towards reagents
Explanation:
Is known ![Kc=\frac{[products]}{[reagents]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5Bproducts%5D%7D%7B%5Breagents%5D%7D)
rised to the power of their number of moles in the balanced reaction. When you have a system at equilibrium with Kc < 1, it means [products] < [reagents] and the system needs energy to react, so if you decrease tempeture the equilibrium shifts towards reagents and less products will be created.
This efect can be discribed with Van´t Hoff equation: 
where we can see that if we decrease temperature (this is T2<T1) in consecuense K2<K1 and reaction doesn´t happen.
Answer:
C2H4O
Explanation:
The chemical molecular formula is C2H4O.
Also note*: Acetaldehyde is the chemical name for this structural formula.
Answer:
A spectator ion refers to a charged atom in a chemical reaction that does not undergo a chemical change.
Hope this helps!!!
Answer:
Since molarity is defined as moles of solute per liter of solution, we need to find the number of moles of nitric acid, and the volume of solution.
molar mass of nitric acid (HNO3) = 1 + 14 + (3x16) = 15 + 48 = 63 g/mole
1.50 g/ml x 1000 ml = 1500 g/liter
1500 g/liter x 0.90 = 1350 g/liter of pure HNO3 (the 0.9 is to correct for the fact that it is 90% pure)
1350 g/liter x 1 mole/63 g = 21.43 moles/liter = 21 Molar HNO3
= 21 Molar of HNO3
