200,000 kilometers is the total distance traveled.
50,000 x 4 = 200,000
please mark brainliest.
19685 because 1 km in inches is 39370 approximately so you just have to cut it in half
A. The number of valence electrons increases as atomic mass increases. == Generally true for the representative elements since atomic mass generally increases with increasing Z.
B. The reactivity of alkali metals increases as atomic mass increases. == True. Atomic mass increases down the column and so does reactivity
C. The reactivity of the halogens increases as atomic mass increases. == False. Reactivity decreases down the column.
D. The number of valence electrons decreases across a period. == False. In general, the number of valence electrons increases across a period, particularly for the representative elements.
Answer:???????????????????????? huh?
Explanation:
of the compound is found to be 5.04 ×
.
Solubility :Solubility can be define as the amount of a substance that dissolves or mixes in a given amount of solvent at specific conditions.
Solubility equilibrium
Ksp = ![[A^{+} ]^{a}](https://tex.z-dn.net/?f=%5BA%5E%7B%2B%7D%20%5D%5E%7Ba%7D)
![[B^{-} ]^{b}](https://tex.z-dn.net/?f=%5BB%5E%7B-%7D%20%5D%5E%7Bb%7D)
Ksp = solubility product constant
A+ = cation in an aquious solution
B- = anion in an aqueous solution
a, b = relative concentrations of a and b
Given,
Solubility = s = 3.60 × 
g/L
molar mass = 288 g/ mol
∴ s= 3.60 × g/L ÷ 288 g/ mol = 1.25 ×
mol/ L
Reaction:
MX3 ⇄ M + 3X
s 3s
=[ 
] [ 
![]^{3}](https://tex.z-dn.net/?f=%5D%5E%7B3%7D)
= solubility product
∴ =![[s]^{} [3s]^{3}](https://tex.z-dn.net/?f=%5Bs%5D%5E%7B%7D%20%5B3s%5D%5E%7B3%7D)
∴ = 3 
∴ = 3 × (3.60 × 
∴ = 503.8848 ×
= 5.04 ×
