The correct answer is internal.
A solid substance whose components like molecules, atoms, or ions are aligned in a highly ordered microscopic composition producing a crystal lattice, which extends in all the directions is known as a crystalline solid or a crystal.
On the other hand, the noncrystalline solid substance in which the atoms and molecules are not aligned in a definite lattice pattern is known as an amorphous solid. Such solids comprise plastic, glass, and gel.
The correct answer is that 1.125 mol of NaOH is available, and 60.75 g of FeCl₃ can be consumed.
The mass of NaOH is 45 g
The molar mass of NaOH = 40 g/mol
The moles of NaOH = mass / molar mass
= 45 / 40
= 1.125
Thus, 1.125 mol NaOH is available
3 NaOH + FeCl₃ ⇒ Fe (OH)₃ + 3NaCl
3 mol of NaOH react with 1 mol of FeCl₃
1.125 moles of NaOH will react with x moles of FeCl₃
x = 1.125 / 3
x = 0.375 mol
0.375 mol FeCl₃ can take part in reaction
The molar mass of FeCl₃ is 162 g/mol
The mass of FeCl₃ = moles × mass
= 0.375 × 162
= 60.75 g
Thus, the amount of FeCl₃, which can be consumed is 60.75 g
Answer:
<span>Dipole-Dipole Forces are common </span><span>to all polar molecules but not non polar molecules.
Explanation:
An Asymmetrical molecule having a region of high electron density (partial negative) and lower density (partial positive) interacts with its neighbor molecules through Dipole-Dipole Interactions. The partial positive part of one molecule interacts with the partial negative part of another.
Example:
Acetone having a partial positive carbon (of carbonyl group) and partial negative oxygen interacts through Dipole-Dipole forces. Hence, acetone does not involves Hydrogen Bond interactions.</span>
Answer:
1, 3, and 4
Explanation:
I'm guessing, but those make the most sense
Moles= number of molecules/Avogadro’s constant
(3.8 x 10^24) /(6.02 x 10^23)
=6.31229..
Volume=moles*24(molar gas volume under STP)
= 6.31229...*24
= 151.5 dm^3 (units mainly used in the UK)
=. 151.5 litres
