Answer:
12000j
mass=1500kg
velocity=4m/s
Kinetic Energy (K E) = 1/2 mv^2
=1/2*1500(4^2)
=1*750*16
=12000j
The one whose molar mass is smaller than sodium.
Fluorine is 19 g
Chlorine= 35.5 g
Bromine= 80 g
so in sodium fluoride, the percent of sodium is the largest.
The student needs to dilute the stock to get the proper concentration. And during the dilution, the molar number of solute will not change. So the volume of stock needed is 2*0.1/1.75=0.114 L. Then dilute to 2.00 L.
Answer:
C5H12 + 8O2 → 6H2O + 5CO2
Explanation:
Pentane + Oxygen --> Water + Carbon dioxide
C5H12 + O2 --> H2O + CO2
The balanced equation is given as;
C5H12 + 8O2 → 6H2O + 5CO2
The principle is the law of conservation of matter that states that matter cannot be created nor destroyed. Hence, the reactants pretty much recombine to form the products.
The number of atoms remains conserved.
