2 Why is it wrong to leave a bottle of anhydrous sodium sulphate or calcium chloride open?
Because they are highly hygroscopic compounds and absorb moisture from air.
What is the oxidation number of Hg?
0 in its compounds, +1 or +2 in its compounds
The oxidation number of zinc on Zn is?
0 in its compounds to +2 in its compounds
Ionic compounds often have higher melting point than metals. Using at least 2 properties of ionic compounds explain why is cookware not made from ionic compounds?
1) Ionic compounds are not good heat conductors 2) Ionic compounds are not malleable
What is bariums oxidation number?
0 in the elemental form and +2 in its compounds

What are 2 energy waves that cant be seen?
Heat waves (infared) and sound waves.
What are the all the main functions of the chloroplast?
1. Absorb light. 2. Create carbohydrates and sugars with chlorophyll.
What are 2 jobs of roots?
absorb water and absorb nutrients
How do you use Infrared On Pokemon Black 2?
Well, you first need a friend and their DS. Then, click Infared on th touch screen
What makes darker colors absorb more heat than lighter colors?
White light is a mixture of colors. When white light strikes a dark object little or no energy is reflected. When white light strikes a white object the energy is mostly reflected, not absorbed. Thus heat is absorbed by dark objects and reflected by light ones.
What happens to light when it hits a surface?
Three things can happen 1. Absorb the light, like black clothing 2. Bounce off the surface, like a mirror 3. Nearly all the light can go through, like a window
Light waves bounce off the surfaces of most objects?
it depends on the surface. the ability for a light wave 2 "bounce off" lies in whether or not the substance will absorb that certain frequency of light...and the type of surface (i.e. smooth or rough)
What is the 7 parts of the Electromagnetic Spectrum?
Radio waves Micro waves Infared radiation Visible light Ultra Violet (UV) X- ray radiation Gamma rays
How many times are electrons energized during photosynthesis?
The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.
How does the Calvin cycle differ from the light-dependent reactions?
1. Calvin cycle takes place in the stroma and light- dependent reactions take place in the granum, also light is not required for all the reactions of Calvin cycle.2. Calvin cycle assimilates CO2 to form organic compounds whereas in light reactions photolysis of water leads the formation of energy rich inorganic compounds.
What is the oxidation number Barium?
0 in the elemental form, +2 in its compounds.
