Answer:its a chemixal change because there are stuff getting mixed togehter making it a chemiacl change
Explanation:
<span>This is due to the fact that the air pressure in that certain section of Earth’s atmosphere decreased. As density of gas particles decreases as air pressure decreases. Therefore, density of gas particles and air pressure have a direct relationship. An increase in air pressure would then effect to an increase in gas particles. </span>
Answer:
The answer is
<h2>877 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density = 19.3 g/cm³
volume = 44.9 cm³
The mass of the gold bar
mass = 19.3 × 44.9 = 866.57
We have the final answer as
<h3>877 g</h3>
Hope this helps you
