New york, 893 - 853 = 40 which is the highest quotient.  

What recommendations would you give to your local community to help to decrease the local effects of human impact on the environment? List 2 recommendations and how they will positively impact your community.

Installing solar panels and replanting 2 trees for every tree that’s been cut down, this will help the atmosphere and deforestation.  

What recommendations would you give to the global governments to help decrease the global effects of human impact on the environment? List 2 recommendations and how they will positively impact our planet.

Constructing using only recycled materials decreases water pollution to 823 ppm and Creating more protected areas decreases air pollution to 368 ppm this will help the environment and oxygen.

A 216-L cylinder holds propane gas at 184.8 kPa of pressure and 127°C. How many moles of propane are in the cylinder?
lbvjy [14]

Answer:

12 moles of propane.

Explanation:

From the question given above, the following data were obtained:

Volume (V) = 216 L

Pressure (P) = 184.8 KPa

Temperature (T) = 127 °C

Number of mole (n) =?

Next, we shall convert 127 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

T(°C) = 127 °C

T(K) = 127 + 273

T(K) = 400 K

Finally, we shall determine the number of mole of propane gas in the container. This can be obtained as follow:

Volume (V) = 216 L

Pressure (P) = 184.8 KPa

Temperature (T) = 400 K

Gas constant (R) = 8.314 L.KPa/Kmol

Number of mole (n) =?

PV = nRT

184.8 × 216 = n × 8.314 × 400

39916.8 = n × 3325.6

Divide both side by 3325.6

n = 39916.8 / 3325.6

n = 12 moles

Thus, 12 moles of propane is present in the cylinder

Q # 1 For chemical reaction ,please help
horrorfan [7]

Answer:- d)  42 kJ of heat is released and the reaction is exothermic.

Solution:- Heat of reaction is the summation of heats of products - reactants.

\Delta H_r_x_n=\sum [products-reactants]

From given information, the energy contained by products is 352 kJ and the energy contained by reactants is 394 kJ. Let's plug in the values in the formula:

\Delta H_r_x_n  = [352 kJ - 394 kJ]

\Delta H_r_x_n  = -42 kJ

Heat of reaction is -42 kJ. The negative sign indicates the heat is released means the reaction is exothermic.  

So, the correct option is the last one, 42 kJ of heat is released and the reaction is exothermic.
