Which has a higher frequency, a neutron or electron? Why?
DanielleElmas [232]
The electron, due to the way an electron orbits the nucleus of an atom. 

According to Quantum Mechanics, electrons do not really orbit the nucleus of an atom. In fact, the most tightly bound state, the 1s orbital, has no angular momentum at all. This would be the state with the most "kinetic energy" and yet there is no "orbital" motion at all in this state.

What is the mass percent of oxygen in sodium bicarbonate (NaHCO3)?
Alenkasestr [34]
The answer is 57.14%.

First we need to calculate molar mass of <span>NaHCO3. Molar mass is mass of 1 mole of a substance. It is the sum of relative atomic masses, which are masses of atoms of the elements.

Relative atomic mass of Na is 22.99 g
</span><span>Relative atomic mass of H is 1 g
</span><span>Relative atomic mass of C is 12.01 g
</span><span>Relative atomic mass of O is 16 g.
</span>
Molar mass of <span>NaHCO3 is:
22.99 g + 1 g + 12.01 g + 3 </span>· <span>16 g = 84 g

Now, mass of oxygen in </span><span>NaHCO3 is:
3 </span>· 16 g = 48 g

mass percent of oxygen in <span>NaHCO3:
48 g </span>÷ 84 g · 100% = 57.14%

Therefore, <span>the mass percent of oxygen in sodium bicarbonate is 57.14%.</span>

A chemist requires 0.802 mol Na2CO3 for a reaction. How many grams does this correspond to?
Komok [63]

Answer:

Ok:

Explanation:

So grams = mols*MolarMass. Here, MolarMass (MM) = 105.99g which can be found using the periodic table. mols is given to be 0.802. We can then plug in to get that it corresponds to 85.0g.

5. Juan's car gets an average of 24 miles per gallon of gas. How far can Juan go on
shtirl [24]

Claim:  Earth's atmospheric CO2 levels were measured over the past 1000 years and correlated with average world temperatures.  The data demostrate that Earth's temperature did not change during the period CO2 levels were steady.  But the past 100 years show a dramatic rise in CO2 levels, with a corresponding rise in world temperatures.  The CO2 rise can be traced back to the start of the industrial revolution, when machines began doing much of the work.  These machine burn fossil fuels and the increased CO2 levels have led to a dramatic rise in world temperatures.  The data clearly show the importance of reducing fossil fuel useage, as well as other CO2 emitters.  A world of incresing temperatures will lead to greater natural disasters, such as storms, flooding, hurricanes, and drought - all of which upset the ecological balance of the planet.
