What mass of carbon dioxide is produced upon the complete combustion of 17.0 LL of propane (the approximate contents of one 5-ga
BlackZzzverrR [31]

The mass of carbon dioxide that is produced will be 31,671 grams or 31.671 kg

<h3>Stoichiometric calculations</h3>

First, the equation of the reaction:

C_3H_8(g)+5O_2(g)-- > 3CO_2(g)+4H_2O(g)

The mole ratio of propane burned to carbon dioxide produced is 1:3.

The density of propane gas is 0.621 g/mL, thus, 17.0 L of propane will weigh:

        Density = mass/volume, mass = 0.621 g/mL x 17000 = 10,557 g

Mole of 10,557 g of propane = 10557/44.1 = 239.39 moles

Equivalent mole of carbon dioxide produced = 239.39 x 3 = 718.16 moles

Mass of 718.16 moles carbon dioxide = 718.16 x 44.1 = 31,671 grams or 31.671 kg

What is a common property of metals? a) insulates from electricity b) conducts electricity c) has very little reactivity' d) is
DedPeter [7]

Answer:

B) conducts electricity

Explanation:

This answer can be answered by the process of elimination.  Metals are excellent conductors of electricity, which means A is out, and metals are also known to have medium reactivity and have high melting points, meaning C and D are also out.

Nitric acid is a key industrial chemical, largely used to make fertilizers and explosives. The first step in its synthesis is th
Hunter-Best [27]

Answer:

The answer is 0.36 kg/s NO

Explanation:

the chemical reaction of NH3 to NO is as follows:

4NH3(g) + 5O2(g) ⟶4 NO(g) +6 H2O(l)

We have the following data:

O2 Volume rate = 645 L/s

P = 0.88 atm

T = 195°C + 273 = 468 K

NO molecular weight = 30.01 g/mol  

we calculate the moles found in 645 L of O2:

P*V = n*R*T

n = P*V/R*T

n= (0.88 atm * 645L/s)/((0.08205 L*atm/K*mol) * 468 K) = 14.78 moles of O2

With the reaction we can calculate the number of moles of NO and with its molecular weight we will have the rate of NO:

14.78 moles/s O2 * 4 molesNO/5 molesO2 * 30.01 g NO/1 molNO x 1 kgNO/1000 gNO = 0.36 kg/s NO
