Answer:
Explanation:
Air is a mixture of roughly 80% nitrogen and 20% oxygen. The diatomic molecules of each type have a Maxwell-Boltzman distribution of velocities.
From the kinetic theory of gases the molecules kinetic energy will depend on the temperature.
Let’s use 300 K as room temperature : The nitrogen molecules have a root mean square velocity ( VRMS ) of 353 m/s. The average for all of the molecules is 347 m/s.
In general in gases of diatomic molecules the speed of sound is 68% of the molecular VRMS .
The density of magnesium is 1.7/cm3, and the density of iron is 7.9g/cm3. Consider a block of iron with a mass of 819 g. What is the mass of a block of magnesium that has the same volume as the block of iron?
The appropriate number of bonds around each carbon atom are four covalent bonds
Please note that carbon has four valence electrons in its outermost shell
<h3>What is an element?</h3>
An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.
An atom is the smallest unit or part of an element which can take part in a chemical reaction.
On a general note, elements are classified as thus:
- Metals, non-metal, and metalloid.
- The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.
- However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,
So therefore, the appropriate number of bonds around each carbon atom are four covalent bonds

D= mass over volume
So, density equals 9.0g divided by 45ml.
SO, D=.25 g/ml
I'm not 100% sure this is correct, though. Best if luck. ♡
It means the process carried by the cell is spontaneous.
