Answer:
1nm = 1000000 mm 1cm=10mm 1m=100cm
Explanation:
so
1,516,000,000 nm = divided by 1000000 is 1516 mm divided by 10 = 151.6 cm divided by 100 = 0.1516 m
0.1516 = 1.516 x 10 -1
because it is 10 less than 1.516
The gain or loss of heat energy is what makes a reaction either endothermic or exothermic. A reaction is said to be endothermic if it absorb heat from the environment while a reaction is described as exothermic if it gives out heat to the environment. During chemical reaction, the bond energy of the reactants needs to be broken and new bond has to be formed in the products. The formation and breaking of bonds requires energy,
This would be the downward movement of water. It begins flowing and continues in a downward movement moving throughout,
