Answer:
Giraffe, rhinoceros, grasshopper, mouse, and deer
Explanation:
Primary consumers eat producers (plants). Therefore, all the animals that eat the plants are primary consumers.
<span>570 torr.
The ideal gas law is
PV = nRT
where
P = pressure
V = volume
n = number of moles of gas particles
R = Ideal gas constant
T = absolute temperature
Since the value n, R, and T remain constant for this problem, that indicates that if the volume is doubled, the pressure will be halved. So the new pressure will be 1.50 atm / 2 = 0.750 atm. Now we just need to convert that from atm to torr. 1 atm is equal to 760 torr, so 0.750 atm * 760 torr/atm = 570 torr.</span>
Answer:
<h2>
<em><u>Data</u></em></h2>
Explanation:
Data are the facts, figures, and other evidence gathered through observations.
The action that could slow a chemical reaction rate is adding
more of a substance to a mixture. The answer is letter d. It does not give time
for the rest of the reactants to be consumed because you are adding more of it
causing to slow the reaction.
Answer:
After increasing the volume, we have 1.81 moles of hydrogen gas in the container
Explanation:
Step 1: Data given
Number of moles hydrogen gas (H2) = 1.24 moles
Volume of hydrogen gas (H2° = 27.8 L
The final volume is increas to 40.6 L
Step 2: Calculate the new number of moles
V1/n1 = V2/n2
⇒with V1 = the initial volume = 27.8 L
⇒with n1 = the initial number of moles H2 = 1.24 moles
⇒with V2 = the final volume = 40.6 L
⇒with n2 = the new number of moles = TO BE DETERMINED
27.8L / 1.24 moles = 40.6 L / n2
n2 = 40.6 / (27.8/1.24)
n2= 1.81 moles
After increasing the volume, we have 1.81 moles of hydrogen gas in the container
