Answer:
Giant structures
Explanation:
An ionic compound is a giant structure of ions. The ions have a regular, repeating arrangement called an ionic lattice . The lattice is formed because the ions attract each other and form a regular pattern with oppositely charged ions next to each other.
Answer:
Number of moles = 558.46 mol
Explanation:
Density = 804 g/L
Molecular formula = C13H28
Molar mass = 184.37 g/mol
Distance = 3680 km
Rate = 3.48 L of fuel per 100. km
Volume is calculated as follow;
3.48 = 100
x = 3680
x = 3680 * 3.48 / 100
x = 128.064 L
Number of moles = Mass / Molar mass
Mass = Density * Volume
Mass = 804 * 128.064 = 102963.456 g
Number of moles = 102963.456 / 184.37
Number of moles = 558.46 mol
Corrosion control refers to measures that are implemented in various fields to control corrosion in:
Soil
Metal
Concrete
Water
Sand
Masonry
Answer:
D, E, A, B, C
Explanation:
The weakest base would be Cl- because HCl is a stronger acid than that of H3O+ from which the water is formed.
Also, for NH3 is a stronger acid than +NH4. Reason is that oxygen is more electronegative than nitrogen and thus NH3 is a stronger acid than NH4+.
The stronger, the acid, the weaker its conjugate base. Thus, NH3 is a weaker base than NH4.
NH2- has the highest basicity because nitrogen is less of an electronegative element than is oxygen. Therefore, it will not want a negative charge.
Hence, the final order in terms of increasing basicity is;
Cl-, H20, NH3, NH4, NH2-
Answer:
0.72 m3
Explanation:
Primero debes calcular el número de litros que vas a tener en total, para esto conviertes 8 horas a minutos, que son 480 minutos, y lo multiplicas por el flujo de 1.5 litros por minutos, por lo que obtendrás 720 litros. Sabiendo que 1000 litros son 1 m3, podemos calcular que 720 litros son 0.72 m3.
