Answer:
35.7 g of NH₄Cl
Explanation:
The reaction is:
Al(NO₂)₃ + 3NH₄Cl → AlCl₃ + 3N₂ + 6H₂O
Ratio is 3:1. 3 mol of ammoium chloride react to produce 1 mol of chloride
We convert the mass of ammoium chloride to moles:
43 g . 1 mol/ 53.45 g = 0.804 moles
(0.804 . 1) / 3 = 0.268 moles of AlCl₃ are formed
Let's convert the moles to mass → 0.268 mol . 133.33 g/1mol = 35.7 g
Answer:
The answer is: The ratio of oxygen atoms to hydrogen atoms in a molecule of sugar is 2 to 1.

Ionization energy: the energy required to remove an electron from a neutral atom. Electron affinity: the energy change when a neutral atom attracts an electron to become a negative ion.
The valence electron of the light metals are all in the range of 1 to 3.
<h3>What are Valence electron ?</h3>
Valence Electron is the number of electrons in the outer shell of an atom which participate in bond formation.
Number of Valence Electron in Boron is 3 and other light metals lighter than Boron have 1 , 2 of Lithium and Beryllium respectively,
The valence electron of the light metals are all in the range of 1 to 3.

Answer:
The final temperature is equal to 240 K or -33.15°C
Explanation:
Given that,
Initial temperature of the gas, T₁ = 47°C = 320 K
Initial pressure, P₁ = 140 kpa
Final pressure, P₂ = 105 kpa
We need to find the final temperature if the volume remains constant. The relation between temperature and pressure is given by :
or
So, the final temperature is equal to 240 K or -33.15°C.
