The chemical formula for Sodium Fluoride is NaF.
Answer: First, here is the balanced reaction: 2C4H10 + 13O2 ===> 8CO2 + 10H2O.
This says for every mole of butane burned 4 moles of CO2 are produced, in other words a 2:1 ratio.
Next, let's determine how many moles of butane are burned. This is obtained by
5.50 g / 58.1 g/mole = 0.0947 moles butane. As CO2 is produced in a 2:1 ratio, the # moles of CO2 produced is 2 x 0.0947 = 0.1894 moles CO2.
Now we need to figure out the volume. This depends on the temperature and pressure of the CO2 which is not given, so we will assume standard conditions: 273 K and 1 atmosphere.
We now use the ideal gas law PV = nRT, or V =nRT/P, where n is the # of moles of CO2, T the absolute temperature, R the gas constant (0.082 L-atm/mole degree), and P the pressure in atmospheres ( 1 atm).
V = 0.1894 x 0.082 x 273.0 / 1 = 4.24 Liters.
Explanation:
Answer:
191 packages of pepperoni
Explanation:
Each pizza would have 13 slices and 15 pieces of pepperoni on each one.
(because same amount of pepperoni and olives)
13 × 15 so each pizza has 195 pieces of pepperoni
138 (number of pizzas) × 195 (pieces of pepperoni)
26910 (pieces of pepperoni) / 141 (amount in each package)
= 190.85
so 191 packages
Co2 = two covalent bonds
ccl4 = 4 covalent bonds
Lih = covalent bond
