Answer:
I think this answer should be 2.33 g H2O
Answer:
Nitrogen (N2) are not compounds because each is composed of a single element.
Answer 1:
This is an example of successful adaptive mutation. Adaptive mutations actually happen because of high levels of stress in the organism's environment caused by the same stressor/s. Here, lots of rabbits being excessively cold all the time due to environment changes caused a lot of extra stress and over time, they successfully mutated to adapt to their environment.
Answer 2:
The answer should be the 4th one. A mutation that doesn't work doesn't always fully go away, but it will become much less common.
the answer is D because if an equal amount of heat is absorbed by the water in the containers, both water temperatures will increase, but Container B's will increase more.
When heat is absorbed by a substance, the substance's temperature increases. The amount that the temperature increases depends on the volume of the substance—the greater the volume, the less the temperature increases.
The water in Containers A and B has the same temperature, but Container A's water has a greater volume. If an equal amount of heat is added to both containers, Container A's water temperature will not increase as much as Container B's.
Answer: The pressure will be equal to 0.19 atm.
Explanation:
The Ideal Gas Equation states the relationship among the pressure, temperature, volume, and number of moles of a gas.
The equation is:
where P = pressure in <em>atm</em>
V = volume in <em>L</em>
n = numbers of moles of gas in <em>mol</em>
R = universal gas constant = 0.08206 
T = temperature in <em>K</em>
Based on the problem,
mass of O2 = 1.0 g
V = 4.00 L
T = 293 K
mol of O2 = ?
P = ?
We need to calculate the moles of O2 before we can use the Ideal Gas Equation. To solve the number of moles, we use the equation:
The molar mass of O2 is 32 g/mol, therefore,
no. of moles of O2 = 0.03125 mol.
Now we substitute the values into the Ideal Gas equation:
Solving for P, we will get
In correct significant figures, P is equal to 0.19 atm.
