Which statement best summarizes the second law of thermodynamics?

The alliance to save energy seeks to increase energy efficiency through _______. a. petitioning consumers to change their habits

TEA [102]

The alliance to save energy seeks to increase energy efficiency through: b. lobbying for policy changes.

<h3> Who is a lobbyist?</h3>

A lobbyist can be defined as an activist whose endeavor and intent is to persuade government officials to enact laws and policies (legislation) that would significantly benefit their group at large.

This ultimately implies that, the alliance to save energy seeks to increase energy efficiency through lobbying for policy changes by gaining access to legislative and executive arms of government, in a bid to influence their thought process.

You have a solution of 0.0020 M HCl. What is the pOH of the solution?

Makovka662 [10]

Answer:

pOH=11.3

Explanation:

pH= -log[H+]=-log[0.002]=2.7

pOH+pH = 14

pOH= 14-2.7=11.3

A sample of oxygen gas at a pressure of 1.19 atm and a temperature of 24.4 °C, occupies a volume of 18.7 liters. If the gas is a

mihalych1998 [28]

Answer:

$\boxed {\boxed {\sf 0.757 \ atm}}$

Explanation:

We are asked to find the pressure of a gas given a change in volume. Since the temperature remains constant, we are only concerned with volume and pressure. We will use Boyle's Law, which states the volume is inversely proportional to the pressure. The formula for this law is:

$P_1V_1= P_2V_2$

Initially, the oxygen gas occupies a volume of 18.7 liters at a pressure of 1.19 atmospheres.

$1.19 \ atm * 18.7 \ L = P_2V_2$

The gas expands to a volume of 29.4 liters, but the pressure is unknown.

$1.19 \ atm * 18.7 \ L = P_2 * 29.4 \ L$

We are solving for the new pressure, so we must isolate the variable $P_2$ . It is being multiplied by 29.4 liters. The inverse operation of multiplication is division. Divide both sides of the equation by 29.4 L.

$\frac {1.19 \ atm * 18.7 \ L}{29.4 \ L} =\frac{ P_2 * 29.4 \ L}{29.4 \ L}$

$\frac {1.19 \ atm * 18.7 \ L}{29.4 \ L} =P_2$

The units of liters cancel.

$\frac {1.19 \ atm * 18.7 }{29.4 } =P_2$

$\frac {22.253}{29.4 } \ atm = P_2$

$0.7569047619 \ atm =P_2$

The original measurements all have 3 significant figures, so our answer must have the same. For the number we calculated, that is the thousandth place. The 9 in the ten-thousandth place to the right of this place tells us to round the 6 up to a 7.

$0.757 \ atm \approx P_2$

The pressure of the gas sample is approximately <u>0.757 atmospheres.</u>

What does the ozone do for us? As in us humans?

dimulka [17.4K]

The ozone layer protects humans from harmful UV rays, because it acts as a sort of filter for any toxic or overpowering waves from damaging our skin. This goes for animals, as well.
