<u>1) balanced chemical equation</u>

2\ C_{4}H_{10}_{(g)}\ +\ 13\ O_{2}_{(g)}\ ->\ 10\ H_{2}O_{(g)}\ +\ 8\ CO_{2}_{(g)}

<u>2) convert mass of CO₂ to moles</u>

=71.9g\ CO_{2}\ x\ \frac{1\ mol\ CO_{2}}{44.01g\ CO_{2}} \\\\=1.633719609

<u>3) multiply by molar ratio</u>

<u />

<u />=1.633719609\ mol\ CO_{2}\ x\ \frac{2\ mol\ C_{4}H_{10}}{8\ mol\ CO_{2}}\\\\=0.4084299023

4) convert moles of C₄H₁₀ to mass

=0.4084299023\ mol\ C_{4}H_{10}\ x\ \frac{58.14g\ C_{4}H_{10}}{1\ mol\ C_{4}H_{10}}\\\\=23.74611452

= 23.7 grams of C₄H₁₀ is needed to produce 71.9 grams of CO₂

Why is the fact that light travels at 300,000 km/s is a consequence of energy conservation?
user100 [1]

Answer is: true.

The law of conservation of energy states that the total energy of an isolated system remains constant; energy can neither be created nor destroyed; it can only be transformed or transferred from one form to another.

Albert Einstein (1879-1955) proposed that a beam of light is a collection of discrete wave packets (photons) with energy hν, where h is Planck constant and ν is frequency.

E = h·ν.

The density of gold is 19.3 g/cm3. What is the volume of a 575 gram bar of pure gold?
Gnoma [55]

Answer:

The  answer to your question is: Volume = 29.79 cm³

Explanation:

Data

Density of gold = 19.3 g/cm3

Mass = 575 grams

Formula

density = mass / volume

Volume = mass/density

Volume = 575 g / 19.3 g/cm3

Volume = 29.79 cm³
