Answer:
6.5
Explanation:
No of moles is the ratio of reacting mass to molar mass
RM - 270.4g
MM - 23+16+1= 40g/mol
270.4/40= 6.76mol
English: The base level of a stream can be defined as the lowest level to which running water can flow. At the base level, the water in the stream has less velocity, which means the water flow has less energy, so its ability to erode or chip away at the land surrounding it is decreased.
Spanish: El nivel base de un arroyo se puede definir como el nivel más bajo al que puede fluir el agua corriente. En el nivel base, el agua de la corriente tiene menos velocidad, lo que significa que el flujo de agua tiene menos energía, por lo que disminuye su capacidad para erosionar o astillar la tierra que la rodea.

Answer:
Explanation:
Net ionic equations must be balanced by both mass and charge. Balancing by mass means ensuring that there are equal masses of each element on the product and reactant sides. Balancing by charge means making sure that the overall charge is the same on both sides of the equation.
