Answer: 1.314 ppm
explain: thats what someone said
Answer:
Explanation:
Mole = no. Molecules/6.02×10^23
Mole = (2.4×10^25)/(6.02×10^23)
Mole = 39.87mole
Molar mass of NaHCO3 is
= 23 + 1 + 12 + 3(16)
= 84g/mol
Mole = mass/molar mass
Mass = Mole × molar mass
Mass = 39.87 × 84
Mass= 3348.84g
Answer: "In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom."
Answer:
air
Explanation:

How are changes of state different from chemical change?
<u>Answer</u><u>:</u>
Physical changes alter only the size, shape, form or matter state of a material. Water boiling, melting ice, tearing paper, freezing water and crushing a can are all examples of physical changes.
On the other hand, chemical changes are a bit different. In a chemical change, a new substance is formed.
