Number 1 is a synthesis reaction because two compounds/elements are coming together to form one compound
Answer:
T₂ = 221.8 K
Explanation:
Given data:
Initial temperature = 57.9°C ( 57.9+273 =330.9 k)
Initial volume = 75.8 mL
Final volume = 50.8 mL
Final temperature = ?
Solution:
According to Charles's law,
V₁ /T₁= V₂/T₂
T₂ = V₂T₁/V₁
T₂ = 50.8 mL ×330.9 k / 75.8 mL
T₂ = 16809.72 mL.K/ 75.8 mL
T₂ = 221.8 K
Answer:
Due to gravitational Force the water exerts more pressure at "ground floor" than at "2nd floor".

The last one
Explanation:
Charges are balanced in a redox reaction
Answer D.
The catalyst is not consumed during a chemical reaction, it just changes the path of the reaction to increase the rate of the chemical reaction by lowering the activation energy.
