Answer:
Carbon dioxide is a product (cellular respiration)
Carbon dioxide is a reactant(photosynthesis)
Carried out in animals(cellular respiration)
Carried out in plants(both)
Chemical reaction(cellular respiration)
Oxygen is a product(photosynthesis)
Oxygen is a reactant(cellular respiration)
Produces usable energy source(photosynthesis)
Your welcome!!! Plz mark brainliest.
There seems to be a mistake. If u mistyped the 'h', then the reaction is single replacement.
Answer:
Copper(II) sulphate – sodium hydroxide reaction
The reaction between copper(Il) sulphate and sodium hydroxide solutions is a good place to start. If you slowly add one to the other while stirring, you will get a precipitate of copper(II) hydroxide, Cu(OH)2.
Answer:
See explanation
Explanation:
The major difference between distance and displacement is that distance is a scalar quantity while displacement is a vector quantity. Scalar quantities have magnitude without direction while vector quantities have both magnitude and direction.
The distance covered by Benjamina in both cases just refer to the difference in her position at each time without reference to the direction in which she changed her position.
Her displacement will clearly mention the direction in which she moved both when she walked to the front door of her apartment and when she walked to a friend's apartment.
We have been given the condition that carbon makes up 35%
of the mass of the substance and the rest is made up of oxygen. With this, it
can be concluded that 65% of the substance is made up of oxygen. If we let x be
the mass of oxygen in the substance, the operation that would best represent
the scenario is,
<span> x = (0.65)(5.5 g)</span>
<span> <em> </em><span><em>x =
3.575 g</em></span></span>
