Answer: 10HSiCl3 + 15H2O → H10Si10O15 + 30HCl
Explanation:
The atomic number defines the number of protons in an atom.
When we convert the given mass in grams and volume in liters to m/v percent, we recall that m/v percent is expressed as grams/100 milliliters. In this case the expression becomes (50 grams/ 2500 L)*(0.1L/100ml), that is equal to 0.002 grams/ 100 mL. Hence the the concentration is equal to 0.2 m/v percent.
If I remember correctly, the answer is <span>Friction force.</span>
the average speed is 23.4 km per hour cause it is total distance over total time equal to average speed
