group: the last no. of electron configuration
Respuesta:
3000 ft
914.4 m
9.144 × 10⁴ cm
Explicación:
Paso 1: Información provista
Longitud: 1000 yd
Paso 2: Convertir 1000 yd a pies (ft)
Usaremos el factor de conversion 1 yd = 3 ft.
1000 yd × 3 ft/1 yd = 3000 ft
Paso 3: Convertir 1000 yd a metros (m)
Usaremos el factor de conversion 1 yd = 0.9144 m.
1000 yd × 0.9144 m/1 yd = 914.4 m
Paso 4: Convertir 914.4 m a centimetros (cm)
Usaremos el factor de conversion 1 m = 100 cm.
914.4 m × 100 cm/ 1 m = 9.144 × 10⁴ cm
What it is made of?
A) Water and Salt- salt is solute, water is solvent
B) Water and Sugar- sugar is solute, water is solvent
C) Water and HCl- HCl is solute, water is solvent
D) Water and NaOH- NaOH is solute, water is solvent
Which of these substances would be a poor conductor of electricity?
Water and Sugar make a poor conductor because sugar does not ionize in water. The other 3 solutions have solutes that ionize and make good conductors.
Answer:
Explanation:
We will need a balanced chemical equation with masses, moles, and molar masses.
1. Gather all the information in one place:
M_r: 2.016 17.03
3H₂ + N₂ ⟶ 2NH₃
m/g: 6.33 × 10⁻⁴
2. Calculate the moles of H₂
3. Calculate the moles of NH₃
The molar ratio is 2 mol NH₃/3 mol H₂.
4. Calculate the molecules of NH₃
There are 6.022 × 10²³ molecules of NH₃/1 mol NH₃.
