Explanation:
the planets rotate around the sun is because the gravity of the sun keeps them in their orbits. if the sun wasnt there, the earth would literally just travel in a straight line. but the gravity of the sun alters its course, making it travel around the sun.
Answer:
2 atm
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 16.0 L
Initial pressure (P₁) = 0.5 atm
Final volume (₂) = 4 L
Final pressure (P₂) =?
The final pressure of the gas can be obtained by using the Boyle's law equation as illustrated below:
P₁V₁ = P₂V₂
0.5 × 16 = P₂ × 4
8 = P₂ × 4
Divide both side by 4
P₂ = 8 / 4
P₂ = 2 atm
Thus, the final pressure of the gas is 2 atm
Answer:
5.72 g ( 1 mol / 180.16 g ) ( 6.022 x 10^23 molecules / mole ) = 1.90x10^23 molecules
Answer:
1. Decomposition of stone due to acid rain.
3. The pink color of a rose.
Explanation:
Chemical changes always end up with new products in an equation, or it has always something to do with chemicals. Physical changes on the other hand, do not result in new products and it just changes the physical properties and physical state of matter of the object.
The only metalloid located in the sixth period of the periodic table is Astatine. Others are located in previous periods.
