Explanation:The scientific inquiry process is the process in which scientists or researchers find an explanation for any natural world phenomena with logic and evidence collected by the systemic method or work.
The scientific inquiry process begins with a question or thinking (observation) for any natural phenomena like why freshwater has low albedo where ice has a high albedo percentage.
Answer:
158 mL
Explanation:
From the question given above, the following data were obtained:
Initial pressure (P₁) = 99.0 KPa
Initial volume (V₁) = 300 mL
Final pressure (P₂) = 188 KPa
Final volume (V₂) =?
The final volume of the gas can be obtained by using the Boyle's law equation as illustrated below:
P₁V₁ = P₂V₂
99 × 300 = 188 × V₂
29700 = 188 × V₂
Divide both side by 188
V₂ = 29700 / 188
V₂ = 158 mL
Therefore, the final volume of the gas is 158 mL.
The required is the amount of Sr(OH)2·8H2O needed to prepare a solution having a concentration of 0.100 M OH-. We start with the concentration of the hydroxide ion to determine the number of moles hydroxide ion for a given volume of 250.0 mL solution.
0.100 mol/L (0.250 L) = 0.4 mol hydroxide ion needed.
We know that, for every mole of Sr(OH)2·<span>8H2O in solution, two hydroxide ions is formed. Thus,
0.4 mol OH- ( 1 mol </span>Sr(OH)2·<span>8H2O / 2 mol OH-) ( 265.76 g / mol) = 53.152 g
Thus, 53.152 grams of </span>Sr(OH)2·<span>8H2O is needed to make a solution with 0.100 M OH-.</span>
The problem ask to calculate the value of x if an iron taht has a mass of 21.5g and has an initial temperature of 1000.0C is submerge in Xg of a water at 20C. So the value of X is letter C. 132 g. I hope you are satisfied with my answer and feel free to ask for more
As you increase the pressure on a gas, its volume will decrease. Think of pushing a piston on a tube of gas. As you decrease the volume, the pressure increases. If you put more volume in a tire, its pressure increases
