Answer:
Explanation:
C2H4 + O2 → CO2 + H2O
eqn is unbalanced - balancing by counting no. of C n H atoms
C=2 n H=4 in one C2H4
so the reaction will form two CO2 + two H2O
counting no. of O atoms: 2*2 + 2*1
=4+2
So we have Barium nitrate with a solubility of 8.7g in 100g water at 20°C.
using that relation
i.e.
8.7g (barium nitrate) =100g (water)
1g barium nitrate = 100/8.7 g water
27g barium nitrate = (100/ 8.7 ) × 27
= 310.34 g
therefore,
you need 310.34g of water is in the jar.
No not all diatomic molecules are non polar
The question needs:
In a 1 M solution of N₂H₄(aq), identify the relative molar amounts of these species. from most to least...
H₂O N₂H₅⁺~OH⁻ H₃O⁺ N₂H₄
H₂O is most
second N₂H₄
N₂H₅ and OH⁻ present in equal amount
H₃O⁺ is zero
because N₂H₄ is weak base it partially ionizes in water as following:
N₂H₄ + H₂O ⇄ N₂H₅⁺ + OH⁻
