Answer: shelter
Explanation:
Producers make food for the rest of the ecosystem through the process of photosynthesis, where the energy of the sun is used to convert carbon dioxide and water into glucose.
Answer:
The pressure of the gas sample will be 0.954 atm.
Explanation:
Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. That is, if the pressure increases, the volume decreases; conversely if the pressure decreases, the volume increases.
Boyle's law is expressed mathematically as:
Pressure * Volume = constant
o P * V = k
To determine the change in pressure or volume during a transformation at constant temperature, the following is true:
P1 · V1 = P2 · V2
That is, the product between the initial pressure and the initial volume is equal to the product of the final pressure times the final volume.
In this case:
- P1= 0.609 atm
- V1= 19.9 L
- P2=?
- V2= 12.7 L
Replacing:
0.609 atm* 19.9 L= P2* 12.7 L
Solving:
P2= 0.954 atm
<u><em>The pressure of the gas sample will be 0.954 atm.</em></u>

2. They taste sour, are electrolytes, and react with active metals to produce hydrogen.
3. You should NEVER taste unknown chemicals because many are poisonous and can destroy body tissue.
4. Most often dyes are used to detect acids. The dyes will turn a certain color which indicates the presence of an acid.
10. You can use litmus to detect wether a solution is a base or an acid.
11. The most common bases I can think of would be: baking soda, laundry detergent, or soaps.
12. Antacids work by neutralizing the acids in your stomach.
13. When an acid and base are mixed together, they produce a salt.
14. Normally pH meters are used, but you can also calculate the pH using math. (yuck)
15. The pH scale measures how acidic or basic a substance is. It ranges from 0-14, with 7 being neutral.
17. pH is very important to the environment as it helps us measure and monitor for safe water conditions. A rise or fall from the average water pH level can indicate chemical pollution.
18. Salt is formed when an acid and base react with each other. It then has a cation of the base, and anion of the acid.
I hope those helps!! (:
You take the grams of CO₂ times Avogadro's number divided by the molar mass.
Proton 26
neutron 0
you can tell how many proton by the atomic number
