<span>67.2 minutes
First convert the runner's speed from mi/h to km/h by multiplying by 1.60934 km/mi, giving
7.1 mi/h * 1.60934 km/mi = 11.43 km/h
Divide the distance by her speed.
12.8 km / (11.43 km/h) = 1.12 h
Convert hours to minutes by multiplying by 60
1.12 h * 60 min/h = 67.2 min</span>

Answer:
True
Explanation:
When Methyl Pentene is introduced in a chemical reaction with dichloromethane then the major product will be bromomethylpentene. There can be small amount of bromo methyl pentene than the amount of methyl pentene introduced for reaction.
I think the answer is radiation I am not hundred percent sure though
NaCl + H2O = HCl + NaOH
FIRST write the equation and balance the equation THEN convert the volume of the gas to moles of the gas PV=nRT THEN according to the stoichiometry of the reaction one mol of gas is produced by one mol of salt. Convert the mol of gas to mol of salt FINALLY calculate the molar mass of the salt and convert the mol of salt to g of salt (m= nxMM)
