1. Given the data below: CH, (g)+2O, (g) à CO, (g)+2H,O (I) CH, (g) + H₂(g) à CH, (g) 2 H, (g) + O₂(g) à 2 H₂O (1) 2C_H_ (g)+7O, (g)à4 CO,(g)+6H_O(I) Calculate the DHⓇ for the reaction 2 CH₂ (g) à CH (g) + H₂ (g) DH = -890.3 kJ DH = -136.3 kJ DH = -571.6 kJ DH = -3120.8 kJ

What is Donnan's theory? What is its importance in biophysical chemistry?

The sun supplies energy at a rate of about 1.0 kilowatt per square meter of surface area (1 watt = 1 J/s). The plants in an agricultural field produce the equivalent of 21 kg of sucrose (C12 H22 O11) per hour per hectare (1 ha = 10,000 m Assuming that sucrose is produced by the reaction m²). 12CO2 (9) + 11H2O(1) → C12H22O11(s) + 120O2(g) AH=5640 kJ calculate the percentage of sunlight used to produce the sucrose – that is, determine the efficiency of photosynthesis in this field. Percent efficiency

What is the role of environmental chemistry in the development of sustainable technologies?

What is a possible testable question (in correct format) That Mrs love might ask for this Sanrio?

It is often said that water vapour amplifies the Earth’s greenhouse effect. Indicate one way that an increased atmospheric concentration water vapour can increase the greenhouse effect and one way that it can decrease the greenhouse effect.

Anna was asked to identify and explain if the equation CO2 (g) → CO2 (I) was an endothermic or exothermic reaction. However she got it wrong. What is her error and what should the answer have been? Anna's statement: The equation is an endothermic reaction because the energy is released from gaseous CO2 to the surroundings to become liquidCO, causing the molecules to speed up.

Environmental science is an interdisciplinary field of study. This means that.

Anna was asked to identify and explain if the equation CO2 (l) → CO2 (g) was an endothermic or exothermic reaction. However she got it wrong. What is her error and what should the answer have been? Anna's statement: The equation is an exothermic reaction because the energy is released from liquid CO2 to the surroundings to become gaseous CO2 causing the molecules to slow down.

5. The car you have been driving has a posted fuel consumption of 10.0 L/100 km (city) and 7.1 L/100 km (highway) according to the EnerGuide information. Overall, your actual fuel consumption has averaged 10.5 L/100 km. a) Is this better or worse than the posted fuel consumption? b) Provide three reasons why your actual fuel consumption may be different from the posted consumption. c) List three ways in which you could improve your fuel consumption (other than buying a new carl).

As you investigate the relationship of oil and plastic, add boxes to the images below. Each box should provide a deep explanation of the relationship between oil, water bottles, and society. (Draw it, please)

reading: The accelerometer keeps track of how quickly the speed of your vehicle is changing. When your car hits another car—or wall or telephone pole or deer—the accelerometer triggers the circuit. The circuit then sends an electrical current through the heating element, which is kind of like the ones in your toaster, except it heats up a whole lot quicker. This ignites the charge which prompts a decomposition reaction that fills the deflated nylon airbag (packed in your steering column, dashboard or car door) at about 200 miles per hour. The whole process takes a mere 1/25 of a second. The bag itself has tiny holes that begin releasing the gas as soon as it’s filled. The goal is for the bag to be deflating by time your head hits it. That way it absorbs the impact, rather than your head bouncing back off the fully inflated airbag and causing you the sort of whiplash that could break your neck. Sometimes a puff of white powder comes out of the bag. That’s cornstarch or talcum powder to…
