Answer:
A. 40 L
Explanation:
Volume and temperature are directly related; when one increases, the other also increases. This can be seen as in the equation V₁ / T₁ = V₂ / T₂. To find the final volume, rearrange the equation to V₂ = V₁ x T₂ / T₁ and plug in your values, then solve.
Answer : The solubility of this compound in g/L is .
Solution : Given,
Molar mass of = 114.945g/mole
The balanced equilibrium reaction is,
At equilibrium s s
The expression for solubility constant is,
Now put the given values in this expression, we get
The value of 's' is the molar concentration of manganese ion and carbonate ion.
Now we have to calculate the solubility in terms of g/L multiplying by the Molar mass of the given compound.
Therefore, the solubility of this compound in g/L is .
Answer: So, a line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.
Explanation:
I believe it’s answer B because even in space gravity plays roles.
Answer:
.0924 moles of NaCl
Explanation:
So you know you have 5.4 g of NaCl and you need to know how many moles there are in this amount of NaCl
- You'll need to find the atomic mass of the compound NaCl to help you solve for moles
- Sodium (Na) on the periodic table has a mass of 22.99
- Chlorine (Cl) on the periodic table has a mass of 35.45
Add these two together----> 22.99 + 35.45 = 58.44
Now you can calculate for moles
<u>Written-out method:</u>
<u>5.4 grams of NaCl | 1 mole of NaCl </u>
| 58.44 grams NaCl = .0924 moles of NaCl
<u>Plug into calculator method:</u>
(5.4 g of NaCl/ 58.44g NaCl= .0925 moles)
