Answer:
No.
Explanation:
No, one mole of peas do not fit inside a house because one mole is equals to 6.022 × 10²³ units which is a very large value. mole only use for atoms, ions and molecules etc due to very small size but mole is not used for big sized materials such as peas and other vegetables etc. So that's why we can conclude that one mole of peas did not fit inside a house.
You dissolve 8.65 grams of lead(II) nitrate in water, and then you add 2.50 grams of aluminum. This reaction occurs: 2Al(s) + 3Pb(NO3)2(aq) → 3Pb(s) + 2Al(NO3)3(aq). What’s the theoretical yield of solid lead? Use the ideal gas resource and the periodic table. A. 5.41 g B. 11.2 g C. 19.2 g D. 28.8 g Reset
Answer: A. 5.41
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Al=\frac{2.50g}{27g/mol}=0.0926moles[/tex]
[tex]\text{Moles of} Pb(NO_3)_2=\frac{8.65g}{331g/mol}=0.0261moles[/tex]
[tex]2Al(s)+3Pb(NO_3)_2(aq)\rightarrow 3Pb(s)+2Al(NO_3)_3(aq)[/tex]
According to stoichiometry :
3 moles of [tex]Pb(NO_3)_2[/tex] require = 2 moles of [tex]Al[/tex]
Thus 0.0261 moles of [tex]Pb(NO_3)_2[/tex] will require=[tex]\frac{2}{3}\times 0.0261=0.0174moles[/tex] of [tex]Al[/tex]
Thus [tex]Pb(NO_3)_2[/tex] is the limiting reagent as it limits the formation of product and [tex]Al[/tex] is the excess reagent.
As 3 moles of [tex]Pb(NO_3)_2[/tex] give = 3 moles of [tex]Pb[/tex]
Thus 0.0261 moles of [tex]Pb(NO_3)_2[/tex] give =[tex]\frac{3}{3}\times 0.0261=0.0261 moles[/tex] of [tex]Pb[/tex]
Mass of [tex]Pb=moles\times {\text {Molar mass}}=0.0261moles\times 207g/mol=5.41g[/tex]
Thus 5.41 g of solid lead will be produced from the given masses of both reactants.

According to Newton's Second Law of Motion, if the force acting on ar
object stays the same, but the mass of an object increases, then
acceleration will...
A. increase
B. decrease
C. remain the same
D. completely stop
Answer:
B
Explanation:
Because the mass of an object increases, then the acceleration will decrease
Which of the following is evidence that groundwater cause erosion and deposition
Answer:You didn't provide examples
Explanation: Groundwater can cause erosion under the surface as it moves through the soil. During the movement an acid is formed which what causes erosion and deposition.
