Why does the base for the atomic mass unit change from hydrogen to carbon?
hydrogen has more binding energy than carbon
How in terms of collision theory how a decrease in concentration can change the rate of a precipitation reaction?
Decrease in conc. means decrease in no. of molecules per unit volume. Since, molecules or atoms will less in number, the no. of colliding particles will be less. This will lead to decreased precipitation
How many atoms are in 1 atomic mass unit of hydrogen?
Atomic mass unit is a unit of mass for all chemical elements, not only for hydrogen. The atomic weight of hydrogen is [1,00784; 1,00811]; the conventional atomic weight is 1,008. 1 atom is equal to 1 amu.
What is the atomic mass unit of hydrogen?
Hydrogen is a non metal element. Atomic mass of it is 1.0079.
What operation do you use if you want to change a larger unit to a smaller unit?
Multiplication.

What does a change in pH of one unit represent in terms of hydrogen ion concentration?
-1 pH unit = *10 concentration
Is a single unit change on the pH scale equivalent to 1 percent change in hydrogen ion concentration?

When output increases the unit labor cost falls and the unit material cost falls why?
because the fixed cost is absorbed into the number of units produced.

Does isotopes of the same element have a different number of neutrons and the same number of protons?
Yes. While positive protons change the element,neutralneutrons do nothing but change the mass of the atom, for example hydrogen, with one proton and one electron becomesdeuterium or heavy hydrogen when a neutron is added. Deuteriumis the hydrogen isotope with a mass of 2 Atomic Mass Unit (AMU), as opposed to normal hydrogen, with only 1 AMU.
Which has an atomic mass unit of 1?
A hydrogen atom of the most common isotope of hydrogen, or a proton or neutron.
Smaller unit change into larger unit?
change quanity to indicated unit, 7600ml= ? kl
How many atoms of hydrogen are in one molecule of ammonum hydroxide?
Ammonium hydroxide does not technically exist as molecules, but its formula unit is NH4OH, which has five atoms of hydrogen in each formula unit.
What is the percentage by mass of sodium (Na) in a formula unit of sodium hydrogen carbonate NaHCO3?
The percentage by mass of sodium (Na) in a formula unit of sodium hydrogen carbonate (NaHCO3) is 27,38 %.
Why do you multiply to change a larger unit to a smaller unit?
to get a unit
