It provides a history on how plants and animals have changed over time
We first need to convert grams of hydrogen chloride to moles.
molarity = moles of solute/liters of solution
To convert from grams to moles, we need to divide by it's molecular mass.
4.5 g HCl * (1 mole HCl/ 36.46 g HCl) = 0.123 moles HCl
0.12 moles/0.9 L = 0.13 M HCl
If they gave you the volume as 900 mL, then that would be 3 sig figs. And the sig figs would be limited to 2 because the mass.If, however, they gave you the volume as 0.9 L, then that would be 1 sig fig. And the final answer would be limited to to 1 sig fig.
I believe it is the sequence of amino acids in a protein
Length is what meter measures
Answer:
Kindly find the attached image.
Explanation:
- All the data related to the potential energy diagram is shown in the attached image.
<em>Reactants, intermediate, products, activation energy (Ea), and enthalpy change (ΔH).</em>
<em />
- Enthalpy change (ΔH) is the difference in energy between reactants and products.
ΔH = E of products - E of reactants.
