A 445N student eats 50g of Pringles. They feel guilty and decide to climb up some stairs to make up for it. How many flights of
krek1111 [17]

Answer:

808

Step-by-step explanation:

One serving of Original Pringles = 28 g           = 150 Cal  

Pringles  ⟶ Cal     50 g × (150 Cal/28 g)          = 268 Cal

Cal ⟶ J                  268 Cal × (4184 J/1 Cal)      = 1.121 × 10⁶ J

J ⟶ N·m                 1.121 × 10⁶ J × (1 N·m/1 J)      = 1.121 × 10⁶ N·m

N·m ⟶ m                1.126 × 10⁶ N·m/455N         = 2460 m

m ⟶ km                 2460 m × (1 km/1000 m)     = 2.46 km

km ⟶ mi                2.46 km × (0.6214 mi/1 km) = 1.53 mi

mi ⟶ ft                   1.53 mi ×(5280 ft/1 mi)         = 8080 ft

ft ⟶ flights             8080 ft × (1 flight/10 ft)        = 808 flights

The student would have to climb 808 flights of stairs to burn off the energy from 50 g of Pringles [that's equivalent to climbing the stairs in the Salesforce Tower (1070 ft) in San Francisco about 7½ times].

When NH3(g) reacts with O2(g), the products of the combustion are NO(g) and H2O(g). What volume of O2(g) is required to react wi
arlik [135]

<u>Answer:</u> The volume of oxygen gas required is 3.75 mL

<u>Explanation:</u>

STP conditions:

1 mole of a gas occupies 22.4 L of volume.

We are given:

Volume of ammonia reacted = 3.00 mL = 0.003 L    (Conversion factor:  1 L = 1000 mL)

The chemical equation for the reaction of ammonia with oxygen follows:

4NH_3(g)+5O_2\rightarrow 4NO(g)+6H_2O(g)

By Stoichiometry of the reaction:

(4 × 22.4) L of ammonia reacts with (5 × 22.4) L of oxygen gas

So, 0.003 L of ammonia will react with = \frac{(5\times 22.4)}{(4\times 22.4)}\times 0.003=0.00375L=3.75mL of oxygen gas

Hence, the volume of oxygen gas required is 3.75 mL
