0.025 g
Sig Fig applies only to numbers that not zero, only except when the zero is after the the number.
For example:
0.0255 is three sigfigs
0.0050 is two sig figs
0.0005 is one sigfig
Mitochondria provides ATP energy in cells after receiving chemical energy. The chloroplast converts energy from the sunlight to chemical energy that is sent to the mitochondria.
Answer:
5.72 g ( 1 mol / 180.16 g ) ( 6.022 x 10^23 molecules / mole ) = 1.90x10^23 molecules
Hydro- meaning Hydrogen.
Carbon- meaning Carbon.
Hydrogen and Carbon. Carbon atoms form the framework, and Hydrogen atoms attach to them in many different configurations.
Hope this helps!
Answer: The data are consistent with the law of conservation of mass because the mass of reactants equals the mass of products
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Given: mass of sodium = 12.8 g
mass of chlorine = 19.6 g
mass of reactants = mass of sodium + mass of chlorine = 12.8 g + 19.6 g = 32.4 g
Mass of product = Mass of sodium chloride = 32.4 g
As mass of reactant = mass of products
, Thus results are in accordance with the law of conservation of mass.
