Answer:
It is a reactant, so it enters the plant.
Explanation:
Hello,
Photosynthesis is the natural process occurring when plants produce sugar and oxygen by using the visible light as the catalyst to undergo the following chemical reaction:
In such a way, it is seen that the carbon dioxide has the role of reactant as it is used by the plant, that is, it enters the plant to allow the photosynthesis to be carried out.
Best regards.
Answer:
proper disposal of radioactive wastes, proper labelling of contents, banning nuclear tests, and using alternative eco-friendly sources of energy.
Answer:
For a hypothesis to be testable means that is it possible to make observations that agree or disagree with it. This statement may or may not be true, but it is not a scientific hypothesis. That's because it can't be tested.
Explanation:
Answer:
To balance the reaction, we should put a 4 in front of Al
Explanation:
<u>Step 1:</u> Data given
AI+3O2->2AI2O3
<u>Step 2:</u> Balance the equation
On the right side we have 2*3 = 6 oxygen atoms
On the left side we have 3*2 = 6 oxygen atoms as well, so those are on both side balanced
On the right side we have 2*2 = 4 Al atoms
On the left side we have only 1 Al atom
We should multiply this by 4 (place a 4 in front of the Al)
4AI + 3O2 → 2AI2O3
Now al atoms are balanced on both sides.
690 Kelvin is the boiling point of this compound.
Explanation:
Enthalpy is the sum of internal energy and the product of pressure and volume that is how much energy is in the substance.
Entropy is the measurement of randomness and measure of thermal energy per unit of temperature.
ΔH vap of compound is 46.55 kJ⋅ mol− or J.MOL-1
ΔS vap is 67.37 J⋅mol−1⋅K−1.
The boiling point or temperature can be calculated by the formula:
T=
T =
= 690 Kelvin
The boiling point is the temperature when atmospheric temperature gets equal to
