1. Using the Hoffman apparatus for electrolysis, a chemist decomposes 50.5 g of water into its gaseous elements. How many grams

of oxygen gas should she get (theoretical yield)? 2. Liquid sodium reacts with chlorine gas to produce sodium chloride. You want to produce 453 g of sodium chloride. How many grams of chlorine gas are needed? 3. You eat 160.0 g of glucose (a handful of M&M's). If glucose, C6H12O6, reacts with oxygen gas to produce carbon dioxide and water, how many grams of carbon dioxide will you have to exhale?

Which statement correctly pairs the climate factor with its effect on temperature? *
allochka39001 [22]

Answer:

A region on top of a mountain is cooler than at the base.

Explanation:

Pressure and temperature have direct relationship with each other. With the decrease in pressure, the temperature decreases and vice versa. When the air rises in the atmosphere, the pressure starts to fall. The low pressure at the peak of the mountains tends to cause the fall in temperature. It is because of this reason that it is cooler at the top of the mountain while the temperature is less cool in the foothills.

A 0.580 g sample of a compound containing only carbon and hydrogen contains 0.480 g of carbon and 0.100 g of hydrogen. At STP, 3
Sati [7]

Answer:

Molecular formula for the gas is: C₄H₁₀

Explanation:

Let's propose the Ideal Gases Law to determine the moles of gas, that contains 0.087 g

At STP → 1 atm and 273.15K

1 atm . 0.0336 L = n . 0.082 . 273.15 K

n = (1 atm . 0.0336 L) / (0.082 . 273.15 K)

n = 1.500 × 10⁻³ moles

Molar mass of gas = 0.087 g / 1.500 × 10⁻³ moles = 58 g/m

Now we propose rules of three:

If 0.580 g of gas has ____ 0.480 g of C _____ 0.100 g of C

58 g of gas (1mol) would have:

(58 g . 0.480) / 0.580 = 48 g of C  

(58 g . 0.100) / 0.580 = 10 g of H

 48 g of C / 12 g/mol = 4 mol

 10 g of H / 1g/mol = 10 moles

Hydroelectricity and tidal energy are similar because
vovikov84 [41]

C.  both sources of energy rely on water.

Explanation:

Hydroelectricity and tidal energy are similar energy sources because they both rely on water.

They harness the power of moving water to produce their energy.

  • Tidal energy is the energy derived from moving water as crashing waves in an ocean.
  • Hydroelectricity is produce when water from a dam channel is used to drive heavy turbines.
  • They are both renewable energy sources.
