Answer: The volume of given ball is 21 L.

Explanation:

Given : Pressure = 1.0 atm, no. of moles = 0.85 mol

Temperature = $25^{o}C = (25 + 273) K = 298 K$

According to the ideal gas equation, formula used is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

$PV = nRT\\1.0 atm \times V = 0.85 mol \times 0.0821 Latm/mol K \times 298 K\\V = 21 L$

Thus, we can conclude that the volume is 21 L.

Which best describes the role of a secondary consumer in a food web?

Mamont248 [21]

Secondary consumers in a food web are carnivores that feed on primary consumers. Consumers are organisms that receive energy by eating other organisms. Specifically, primary consumers are those that feed on producers. Producers are those that are able to produce their own food, like plants. Meanwhile, secondary consumers, like humans, eat primary consumers such as cows.

Please help with #2 and #3

Vaselesa [24]

Answer:

2. $V_2=17L$

3. $V=82.9L$

Explanation:

Hello there!

2. In this case, we can evidence the problem by which volume and temperature are involved, so the Charles' law is applied to:

$\frac{V_2}{T_2}=\frac{V_1}{T_1}$

Thus, considering the temperatures in kelvins and solving for the final volume, V2, we obtain:

$V_2=\frac{V_1T_2}{T_1}$

Therefore, we plug in the given data to obtain:

$V_2=\frac{18.2L(22+273)K}{(45+273)K} \\\\V_2=17L$

3. In this case, it is possible to realize that the 3.7 moles of neon gas are at 273 K and 1 atm according to the STP conditions; in such a way, considering the ideal gas law (PV=nRT), we can solve for the volume as shown below:

$V=\frac{nRT}{P}$

Therefore, we plug in the data to obtain:

$V=\frac{3.7mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm}\\\\V=82.9L$

Best regards!
