Answer:
Each cell contributes power of 14.7 Watts.
Explanation:
Total power generated by alkali furl cells = 14,800 Watts
Total number of fuel cells = 1,008
Power produced by one fuel cell = x
Total power generated = 
Each cell contributes power of 14.7 Watts.
Ping pong ball - 0.0840 g

Marble - 2.711 g
Answer:
Filtration is a process in which insoluble matter is separated from a liquid. Filtration is a separation process in which a mixture is passed through a filter that allows one component to pass-through but blocks another component from passing through because of its matter and consistency. Heterogeneous mixtures can be separated into their respective constituents. For example, a mixture of mud and water can be separated through filtration process easily, because water being liquid will pass through the filter paper easily but the mud will not because of it being solid
Answer : When we are diluting a solution of
from 0.33 m to 0.025 m of 25 ml we will need
1.89 ml of 0.33 m solution for the dilution.
Explanation : Using the formula
we can calculate the
Answer:
Mass = 1785.6 g
Explanation:
Given data:
Moles of lead oxide = 8 mol
Mass in grams = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Mass = number of moles × molar mass
Molar mass of PbO = 223.2 g/mol
Now we will put the values.
Mass = 8 mol × 223.2 g/mol
Mass = 1785.6 g
Thus 8 moles of lead oxide have 1785.6 grams.
