Answer: Keq= [CO2]^6[H2O]^6/ [O2]^6
Explanation:
B. The study of matter and energy.
Because physical science is everything that doesn't include organic things.
The southern pacific ocean has a similar symmetric pattern to the seafloor ages of the Atlantic ocean. In the Pacific, the seafloor on one side of the youngest crust gets very old but the seafloor on the other side is much younger.
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
(mass)(ΔT)(Cs) = (Cs)(ΔT)(mass)
(140.0g)(95.00−x)(4.184)=(4.184)(x−25.00)(400.0g)
Solve for x
55647.2 - 585.76x = 1673.6x – 41840
-585.76x – 1673.6x = -41840 – 55647.2
-2,259.36x = -97,487.2
-2,259.36x / -2,259.36 = -97,487.2 / -2,259.36
X = 43.15
