Answer:
number of plants that grow in the ocean
Explanation:
<em>The dependent variable would be the number of plants that grow in the ocean.</em>
The dependent variable is the actual variable being measured in an experiment. The value of dependent variables is directly affected by another variable in an experiment - the independent variable. The latter is the manipulatable variable that is directly inputted during experiments.
In the illustration, the main aim of the experiment is to determine how CO2 levels in ocean water affect the number of plants that can grow in the ocean. The manipulatable input variable would be the CO2 while the outcome variable - the dependent variable - would be t<u>he number of plants that grow in the ocean.</u>
Answer: C4O2 or O=C=C=C=C=O.
Answer:
1.654 atm.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and V are constant, and have different values of P and T:
<em>(P₁T₂) = (P₂T₁)</em>
<em></em>
P₁ = 1.0 atm, T₁ = 25°C + 273 = 298 K,
P₂ = ??? atm, T₂ = 220°C + 273 = 493 K,
- Applying in the above equation
<em>(P₁T₂) = (P₂T₁)</em>
<em></em>
<em>∴ P₂ = (P₁T₂)/(T₁) </em>= (1.0 atm)(493 K)/(298 K) = <em>1.654 atm.</em>
They provide a place for marine life to flourish, that would otherwise most-likely go extinct because of the constant decrease of natural reefs in our oceans.
