Answer:
C) The products have more energy stored in their chemical bonds.
Explanation:
In such reactions that absorb energy, the products have more energy stored in their chemical bonds.
For endothermic changes, heat is absorbed from the surrounding hence the surrounding becomes colder at the end of the changes.
The heat energy level of the products is higher than that of the reactants.
- Exothermic reactions releases heat to the surroundings. The sum of heat contents of the products is less than that of the hat contents of the reactants.
- Examples of such processes are burning and dissolution.
The standard temperature and the pressure for a gas are 273 K and 1 atm (1.0 x 10⁵ Pa) respectively.
For this question, combined gas law can be added.
PV/T = K (constant)
for both situations that law can be added as;
P₁V₁/T₁ = P₂V₂/T₂
P₁ = 97 kPa P₂= 1.0 x 10⁵ Pa
T₁ = 303 K T₂ = 273 K
V₁ 140 mL V₂ = ?
V₂ = 122.3 mL
Hence, the volume of gas at STP = 122.3 mL
Answer:
When the Moon is the farthest away, it's 252,088 miles away. That's almost 32 Earths.
Explanation: The orbit is not a perfect circle.
35.0 g would be the mass according to law of mass conservation in an isolated system in this case closed jar
Answer:
6
Explanation:
If there are 6 electrons and it has a balanced charge, there also must be six protons.
