Each of the terms of the sequence is a multiple of 4, starting with 4 x 1 = 4, so the rule for this sequence is 4n.
The correct answer is: [B]: " CO " .

The answer is no because producers need the energy from the sun in order to produce. Hope this helped!
The answer could honestly be as simple as "Putting rock salt on the roads during a snowstorm is an example of a chemical reaction" but due to lack of context I'm not sure, hope this helps anyways!
Answer:
0.877 mol
Step-by-step explanation:
We can use the<em> Ideal Gas Law </em>to solve this problem.
pV = nRT Divide both sides by RT
n = (pV)/(RT)
Data:
p = 646 torr
V = 25.0 L
R = 0.082 06 L·atm·K⁻¹mol⁻¹
T = 22.0 °C
Calculations:
(a) <em>Convert the pressure to atmospheres
</em>
p = 646 torr × (1 atm/760 torr) = 0.8500 atm
(b) <em>Convert the temperature to kelvins
</em>
T = (22.0 + 273.15) K = 295.15 K
(c) <em>Calculate the number of moles
</em>
n = (0.8500 × 25.0)/(0.082 06 × 295.15)
= 0.877 mol
