Chemical weathering is when things get weathered chemically
Answer:
The answer to your question is 160 g of Calcium
Explanation:
Data
mass of Calcium = ?
mass of Hydrogen = 8 g
reactant = HCl
Process
1.- Write the balanced chemical reaction
Ca + 2HCl ⇒ CaCl₂ + H₂
2.- Look for the atomic number of Calcium and hydrogen
Calcium = 40 g
Hydrogen = 1 x 2 = 2 g
3.- Use proportions to calculate the mass of calcium needed.
40 g of Calcium ---------------- 2 g of hydrogen
x ----------------- 8 g of hydrogen
x = (8 x 40) / 2
x = 320/2
x = 160 g of Calcium
Climate is an area's long-term weather patterns
Answer:
V₂ = 155.2 mL
Explanation:
Given data:
Initial volume =175.6 mL
Initial pressure =0.9648 atm
Initial temperature = 298.1 K
Final temperature = 273 K
Final volume =?
Final pressure = 1 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₁V₁/T₁ = P₂V₂/T₂
V₂ = P₁V₁T₂ /T₁P₂
V₂ = 0.9648 atm × 175.6 mL × 273 k / 298.1 K× 1 atm
V₂ = 46251.4 atm. k. mL/ 298.1 K× 1 atm
V₂ = 155.2 mL
