The answer is C
Why:
A - this is natural
B - water is natural
D - this is also natural
C- this is right because when we breathe out we produce more carbon dioxide then we breathed in.
Answer:
Tend to keep the product concetration <u>low</u> and therefore drive the reaction <u>righward</u>
Explanation:
The fact the products of a reaction are quickly consumed by the next one would tend to keep the product concetration low and therefore drive the reaction righward (to the products).
This happens because the system will not achive equilibrium between the reactants and the product, and will keep producing it util the system achives equilibrium or the reactants dry out.
4. A
because PbCl2 is an ionic compound and it's solid, so it's a substance.
It cannot be mixture, because it's a pure molecule.
5. D
despite that both substances are gases, colorless they are different molecules, so they should have different either chemical and physical properties
6. C
this substance made from W atoms and others are made from molecules
The balanced equation for the generation of sugar from
sunlight water and CO₂ is
6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
carbon dioxide + water → sugar + oxygen
<span>The process of photosynthesis occurs
when the chlorophyll present in the leaves of plants absorb sunlight to make
food in the presence of carbon dioxide (enters through the stomata of leaves)
and water (absorbed from the roots). As a result of this reaction sugar and
oxygen is formed. After that sugar is converted in to starch and oxygen is released
into air.</span>
