A student mixed 68 grams of vinegar with 7 grams of baking soda. The solution bubbled as sodium acetate (white solid), carbon dioxide, (gas) and water were produced. If sodium acetate and water in the flask weigh 60 grams, how much carbon dioxide was lost to the environment?
Answer:
15 grams of carbon dioxide
Explanation:
You would just add 68+7 and that gives you 75. Next subtract 75-68 and that gives you 15.
Compare and contrast a natural and synthetic resource.
Answer:
The difference between natural and synthetic material is that natural materials are those that can be found in nature while synthetic materials are those that are chemically produced in a lab. Note that a natural material that is altered physically is still considered a natural material.
Many different materials are used for clothing and other products. Common natural materials include cotton, paper and wool. Common synthetic materials include plastics, which are typically polymers. Synthetic materials are often designed to be stronger and more resistant to damage than any commonly available natural material. There is a limited amount of natural materials available, but a near limitless amount of potential materials that can by synthetically created.

How much energy (joules) is needed to heat 250 grams of water from 22 °C to 99 °C?
Answer:
[tex]\boxed {\boxed {\sf 80, 465 \ Joules}}[/tex]
Explanation:
We can use the specific heat formula, which is:
[tex]q=mc \Delta T[/tex]
Where q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.
We know the mass is 250 grams. The specific heat capacity of water is 4.18 joules per gram degree Celsius. Let's find the change in temperature.
ΔT = final temperature - initial temperatureΔT= 99°C- 22°ΔT= 77°CNow we know all the values:
m= 250 g c= 4.18 J/ g °CΔT= 77°CSubstitute the known values into the formula.
[tex]q=(250 \ g) (4.18 \ J/g \textdegree C)(77 \ \textdegree C)[/tex]
Multiply the first 2 numbers together. The grams will cancel out.
[tex]q=1045 \ J/ \textdegree C (77 \textdegree C)[/tex]
Multiply again. This time the degrees Celsius will cancel out.
[tex]q=80465 \ J[/tex]
The energy needed is 80, 465 Joules.

The atmosphere is full of nitrogen gas (N2). But plants cannot use nitrogen in this form. Summarize the roles of bacteria in making nitrogen available to plants and in returning nitrogen to the atmosphere.
They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle.
