The density at 1,291 km from the surface of the planet is
[ (1,291 - planet's radius)/(planet's radius) ] ^ some power .
Answer:
The answer is: the body contains chemicals called buffers that resist changes in pH
When you exercise vigorously, the muscle will produce more carbon dioxide which will makes the blood more acidic. Human blood have some mechanism that could prevent the blood pH to stray further from the optimal range. One of the buffer that keep carbon dioxide acidity would be sodium bicarbonate.

<h2>
it just be like that sometimes my dude</h2>
Well, water is composed H2 gas and O2 gas in a 2:1 ratio, and the bubbles that form at the bottom of the pan is just the water changing from a liquid to a gas, and im pretty sure its water vapor that comes out of the pan. I hope that helped??? :)
Answer:
The rearrangement of particles in a physical change.
Explanation:
When things are liquid the particles tend to be spread out because they aren't tightly compacted as they would be with a solid. So when liquid gold is changing from a liquid to a solid the properties are changing and the particles in the gold are getting closer together.
<h3><u>Answer;</u></h3>
= 5.1 g/L
<h3><u>
Explanation;</u></h3>
Using the equation;
PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.
Number of moles is 1 since one mole has a mass equivalent to the molar mass.
Therefore; We can find the volume and thus get the density.
<em>V = nRT/P</em>
<em> = (1 × 0.08206 × 237)/3.510</em>
<em> = 5.5408 L</em>
<em>Hence; Density = mass/volume </em>
<em> = 28.26 g/5.5408 L</em>
<em> = 5.1 g/L</em>
<em>The Density is 5.1 g/L or 0.005 g/cm³</em>
