Answer:
1.427x10^-3mol per L
Explanation:
![Y(IO_{3} )_{3} ---- Y^{3+} +IO_{3} ^{3-}](https://tex.z-dn.net/?f=Y%28IO_%7B3%7D%20%29_%7B3%7D%20----%20Y%5E%7B3%2B%7D%20%2BIO_%7B3%7D%20%5E%7B3-%7D)
I could use ⇌ in the math editor so I used ----
from the question each mole of Y(IO3)3 is dissolved and this is giving us a mole of Y3+ and a mole of IO3^3-
Ksp = [Y^3+][IO3-]^3
So that,
1.12x10^-10 = [S][3S]^3
such that
1.12x10^-10 = 27S^4
the value of s is 0.001427mol per L
= 1.427x10^-3mol per L
so in conclusion
the molar solubility is therefore 1.427x10^-3mol per L
→ ![2CrCl_3 + 3Co](https://tex.z-dn.net/?f=2CrCl_3%20%2B%203Co)
Explanation:
- The products formed are chromic chloride and cobalt.
Chromium + Cobaltous Chloride = Chromic Chloride + Cobalt
- Type of reaction is Single Displacement (Substitution) which is there is a displacement of one atom.
Reactants used in the reaction are -
- Chromium
![(Cr)](https://tex.z-dn.net/?f=%28Cr%29)
- Cobaltous Chloride
![(CoCl_2)](https://tex.z-dn.net/?f=%28CoCl_2%29)
Products formed in the reaction are -
- Chromic Chloride
![(CrCl_3)](https://tex.z-dn.net/?f=%28CrCl_3%29)
- Cobalt
![(Co)](https://tex.z-dn.net/?f=%28Co%29)
Hence, the chemical reaction is as follows -
→![CrCl_3 + Co](https://tex.z-dn.net/?f=CrCl_3%20%2B%20Co)
For balancing the above chemical equation we need to add a coefficient of 2 in front of chromium and of 3 in front of cobalt(II)chloride on right-hand-side while of 2 in front of chromium chloride and of 3 in front of carbon monoxide on left-hand-side of the equation.
Hence, the balanced equation is -
→ ![2CrCl_3 + 3Co](https://tex.z-dn.net/?f=2CrCl_3%20%2B%203Co)
Answer:
motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.

Mass of molecule (g) = Mr of substance over avarogado constant
Answer:
The answer is D. gamma rays
Explanation:
A radioactive atom can have three different types of emission:
alpha particles (α) = they have a mass of 4 amu and they have a very low penetrating power.
Beta particles (β) = they have 5x
amu and they have an intermediate penetrating power
Gamma rays (γ) = they are not particles basically just energy so its mass is ≈ 0 and its penetrating power is higher
For this reason Gamma emissions (γ) has the smallest mass value.
