Click on the graph to show the correct relationship between altitude and boiling point
spin [16.1K]

Explanation:

This graph shows that an increase in altitude causes a relative decrease in  boiling point temperatures. The two variables, it can be said, are inversely proportional.

This is because, with an increase in altitude, there is a proportionate decrease in air pressure. This means the vapor pressure of the fluid becomes strong enough, at a relatively lower temperature, to overcome the air pressure and for the liquid to boil.

This is why water can even boil without inputting heat into it but rather by just reducing the ambient air pressure.

A compound is 70.0% iron and 30.0% oxygen. Its molecular mass is 479.1 g/mol. Determine the
Strike441 [17]

Answer:

Fe_6O_9

Explanation:

Hello there!

In this case, since these problems about formulas, firstly require the determination of the empirical formula, assuming that the given percentages are masses, we can calculate the moles and mole ratio of oxygen to iron as shown below:

n_{Fe}=70/55.85=1.25\\\\n_O=30/16=1.875

In such a way, by rounding to the first whole number we multiply by 8 and divide by 5 to obtain:

Fe_{2}O_{3}

Whose molar mass is 159.69 g/mol and the mole ratio of the molecular to the empirical formula is:

479.1/159.69=3

Therefore, the molecular formulais:

Fe_6O_9

Regards!

How does fermentation that causes dough to rise differ from fermentation in muscles?
mote1985 [20]
Fermentation that causes dough to rise is alcoholic acid, and this is when the alcohol is rising and leaving the dough. In a human, we don't have alcohol, or else we would be drunk after we work out. Instead, we have Lactic Acid fermentation, and this is when you use up too much oxygen, so fermentation make us really tired or else, we wouldn't be able to keep working out.

Why do electrons gain energy?
Novay_Z [31]

Electrons can gain the energy it needs by absorbing light. If the electron jumps from the second energy level down to the first energy level, it must give off some energy by emitting light. The atom absorbs or emits light in discrete packets called photons, and each photon has a definite energy.
