Answer:
it is false Sodium acetate NEVER precipitates
Explanation:
Step one look for the longest chain of carbon atoms
Longest chain is 7 C atoms
Step 2 look for double bonds or others functional groups
it is present in 3rd carbon
Therefore IUPAC name is 3-heptene
From point of stereochemistry it can also be written as trans-3-heptene as the hydrogens are placed in opposite side of the C=C bond.

Answer:
A dunes windward side is the side where the wind is blowing and pushing material up. A dunes slip face is simply the side without wind. A slipface is usually smoother than a dunes windward side. A collection of dunes is called a dune belt or dune field.

Answer:
pH

OH- concentration 28.84
Explanation:
KOH dissociates into K+ and OH-. The ratio of K+ and OH- ion is 1:1
In any aqueous solution, the H3O+ and OH - must satisfy the following condition -
![[ H_3O^+] [OH^-] = k_w](https://tex.z-dn.net/?f=%5B%20H_3O%5E%2B%5D%20%5BOH%5E-%5D%20%3D%20k_w)
![[ H_3O^+] = \frac{k_w}{ [OH^-]}](https://tex.z-dn.net/?f=%5B%20H_3O%5E%2B%5D%20%3D%20%5Cfrac%7Bk_w%7D%7B%20%5BOH%5E-%5D%7D)

Answer:
Mass of chlorine = 47.22 g
Explanation:
Given data:
Mass of sodium = 30.5 g
Mass of chlorine= ?
Solution:
Chemical equation:
2Na + Cl₂ → 2NaCl
Number of moles of Na:
Number of moles = mass/molar mass
Number of moles = 30.5g/ 23 g/mol
Number of moles = 1.33 mol
Now we will compare the moles of Cl
₂ with Na from balance chemical equation.
Na : Cl
₂
2 : 1
1.33 : 1/2×1.33 = 0.665 mol
Mass of chlorine gas:
Mass = number of moles × molar mass
Mass = 0.665 mol × 71 g/mol
Mass = 47.22 g
