Answer : The balanced chemical reaction will be:
Explanation :
As per question when copper(II) oxide react with sulfuric acid then it gives copper(II) sulfate and water.
This reaction is known as double displacement reaction in which cation of two reactants exchange their places to give two different products.
The balanced chemical reaction will be:
20.7 Degree celsius is the temperature of Zippy's room.
Explanation:
The initial conditions of the kookie cola will be depicted by P1,V1 and T1.
P1= 36.5 psi or 2.4816 atm
V1= 355ml or 0.35 L
T1= 275.5K
The final conditions are given P2,V2 and T2
P2= 38.9 psi or 2.6469 atm
V2 = 355 ml or 0.35 L
also the solubility of the carbon dioxide does not change with temperature.
Applying the formula
P1VI/T1=P2V2/T2
since volume does not change and remains constant.
It can be written as:
P1/T1=P2/T2
= 2.4816/275.5=2.6469/T2
T2= 293.85 K
Answer:
The change of state requires energy.
Explanation:
Instead of the energy changing the temperature the heat energy is used by changing its form.
Jupiter, Saturn are two planets that have solid cores.
The dependent variable is 'Number of plants' which is the correct answer.
The independent variable is CO₂ levels in ocean water, however, the growth of plants in ocean water depends on the CO₂ levels. Higher CO₂ is level is conducive to the growth of plants.
Plants use CO₂ and water in photosynthesis to prepare food in the presence of light.
6CO₂ + 6H₂O + light energy = C₆H1₁₂O₆ + 6O₂.
