Ionic bonds are the weakest bonds.
630g
Explanation:
firstly the equation has to be balanced. 2H2+o2>2H2o.
finding the mole of hydrogen?
mole = 70/2 which is equal to 35 mole of hydrogen.
35 mole of hydrogen is equal to the mole of water.
finding the mass of water=?
35=mass/18
mass= 35*18=630g of water
Answer:
is the solubility of 
in 0.10 M 
.
Explanation:
Concentration of calcium nitrate = ![[Ca(NO_3)_2]=0.10 M](https://tex.z-dn.net/?f=%5BCa%28NO_3%29_2%5D%3D0.10%20M)
![[Ca(NO_3)_2]=0.10 M=[Ca^{2+}]](https://tex.z-dn.net/?f=%5BCa%28NO_3%29_2%5D%3D0.10%20M%3D%5BCa%5E%7B2%2B%7D%5D)
Solubility product of the calcium fluoride = 
Solubility of calcium fluoride in calcium nitrate solution :
(0.10+S) (2S)
The expression of solubility is given by :
![K_{sp}=[Ca^{2+}][F^-]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BCa%5E%7B2%2B%7D%5D%5BF%5E-%5D%5E2)
Solving for S:
is the solubility of in 0.10 M .
Glucose + Oxygen > Carbon Dioxide
C(6)H(12)0(6)+ 0(2) >CO(2)
Answer:
So she is very anxious because she has to wait 345600 seconds
Explanation:
60 second = 1 minute
60 minute = 1 hour
1 hour has 3600 seconds (60*60)
24 hour = 1 day
3600 second * 24 hours =
1 day has 86400 seconds so in four days
86400 * 4 = 345600
