Even though the same amount of energy was transferred into both substances from the air, the isopropanol evaporated while the wa

ter did not. Why do you think the isopropanol changed phase, but the liquid water did not ... Earlier in the lesson, you observed isopropanol and water drops on a paper towel.HELP HELP PLS

Answer:

The isopropanol evaporated while the water did not because the molecules don't stick together as strongly as the molecules in the water do. The water would need more energy transferred in, in order to evaporate.

san4es73 [151]

Answer:

                    1.8 moles of O₂

Explanation:

                     The balance chemical equation for said double replacement (photosynthesis) reaction is as follow;

                           6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

According to balance chemical equation,

                 6 moles of O₂ are produced by  =  6 moles of CO₂

So,

                1.8 moles of O₂ will be produced by  =  X moles of O₂

Solving for X,

                     X =  1.8 mol × 6 mol / 6 mol

                     X =  1.8 moles of O₂

Stoichiometric problems in which moles are given and moles or other reactant or product asked are the simplest problems. One should only write the balanced chemical equation and perform above method to find the required moles.

1) Look at the graph. What is the independent variable and the dependent variable?
Xelga [282]

Answer:

Independent Variable = Years

Dependent Variable = Number of Mobiles phone owners

Explanation:

Independent variables are plotted on x-axis and the dependent variables are plotted on y-axis.

In given graph the "Years" belong to x-axis hence, years are the independent variables.

Also, "Number of Mobile phones owners" belong to y-axis hence, this number is the dependent variable.
