Answer:
The correct option is;
3. A homogeneous mixture of two compounds
Explanation:
An homogeneous mixture is one where the components of the mixture are evenly dispersed such that the individual components cannot be seen to be isolated and distinguishable and having a constant composition of the constituents
The image displays three atoms (red circle, cyan triangle, and orange rectangle). The red circle appear to be bonded in pairs while the cyan triangles are bonded to the orange rectangles making a total of two compounds
The arrangement of the compounds in the mixture appear to be very evenly distributed to suggest an homogeneous mixture
The visibility of the compounds should be for an illustrative purpose.
A structural formula for an organic compound that depicts each valence bond as a short line especially : the hexagonal ring formula for benzene
A producer gets it's matter from it's surroundings. E.g a plant will get minerals and water from the ground through it's roots for photosynthesis.
Plants can also produce food by using the sun's light for photolysis of the water molecules. (Basically splitting the H20 into Hydrogen and O2 (oxygen gas). They release oxygen back into the air and combine the Hydrogen ion with carbon dioxide that they obtained from the air to create sugar (glucose) which is basically chemical food for the plants. This is the summed up process of photosynthesis.
Molar mass of lead is 207.2 grams/mole (according to the periodic table)
Molar mass of Sulfate
Sulfur + 4 Oxygen
Molar mass of Sulfur + molar mass of 4 oxygen = 96 grams/mole for sulfate
207.2 + 96.6 = 303.8 grams/mole for Lead(II) Sulfate (I might be .5 grams of, down or up)
Answer:
the answer is 1.17
Explanation:
D= m/v
=2.63/2.25=1.17g/mL
I don't know if it will sink or not
