1. Conserve Water

Use less water so excess runoff and wastewater will not flow into the ocean.
2. Reduce Pollutants

Choose nontoxic chemicals and dispose of herbicides, pesticides, and cleaning products properly.
3. Reduce Waste

Cut down on what you throw away.
Around Town

4. Shop Wisely

Choose sustainable seafood. Buy less plastic and bring a reusable bag.
5. Reduce Vehicle Pollution

Use fuel efficient vehicles, carpool or ride a bike.
6. Use Less Energy

Choose energy efficient light bulbs and don't overset your thermostat.
On the Water

7. Fish Responsibly

Follow "catch and release" practices and keep more fish alive.
8. Practice Safe Boating

Anchor in sandy areas far from coral and sea grasses. Adhere to "no wake" zones.
9. Respect Habitat

Healthy habitat and survival go hand in hand. Treat with care.
10. Anytime, Anywhere

Volunteer

Volunteer for cleanups at the beach and in your community. You can get involved in protecting your watershed too!

Hope this helps

A 2.00-g sample of a large biomolecule was dissolved in 15.0 g carbon tetrachloride. the boiling point of this solution was dete
Katarina [22]
We will use boiling point formula:

ΔT = i Kb m 

when ΔT is the temperature change from the pure solvent's boiling point to the boiling point of the solution = 77.85 °C - 76.5 °C = 1.35

and Kb is the boiling point constant =5.03

and m = molality 

i = vant's Hoff factor

so by substitution, we can get the molality:

1.35 = 1 * 5.03 * m

∴ m = 0.27

when molality = moles / mass  Kg

           0.27 = moles /  0.015Kg

∴ moles = 0.00405 moles

∴ The molar mass = mass / moles
                               = 2 g /  0.00405 moles 
                               = 493.8 g /mol

erik [133]

Answer:

Explanation:

The changes in temperature caused by a reaction, combined with the values of the specific heat and the mass of the reacting system, makes it possible to determine the heat of reaction.

Heat energy can be measured by observing how the temperature of a known mass of water (or other substance) changes when heat is added or removed. This is basically how most heats of reaction are determined. The reaction is carried out in some insulated container, where the heat absorbed or evolved by the reaction causes the temperature of the contents to change. This temperature change is measured and the amount of heat that caused the change is calculated by multiplying the temperature change by the heat capacity of the system.

The apparatus used to measure the temperature change for a reacting system is called a calorimeter (that is, a calorie meter). The science of using such a device and the data obtained with it is called calorimetry. The design of a calorimeter is not standard and different calorimeters are used for the amount of precision required. One very simple design used in many general chemistry labs is the styrofoam "coffee cup" calorimeter, which usually consists of two nested styrofoam cups.

When a reaction occurs at constant pressure inside a Styrofoam coffee-cup calorimeter, the enthalpy change involves heat, and little heat is lost to the lab (or gained from it). If the reaction evolves heat, for example, very nearly all of it stays inside the calorimeter, the amount of heat absorbed or evolved by the reaction is calculated.
