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
Physical properties include: appearance, texture, color, boiling point, melting point, ect.
The correct answer is B. The nitrogen in the nitrogen cycle originate from the atmosphere. It forms approximately 78% of the Earth's atmosphere. However, this form is not usable because it is in its most stable form therefore unreactive. This nitrogen gas needs to be converted into nitrate compound for it to be usable. Then, the nitrogen cycle starts.<span />
Answer:
I have for Decompostion
Explanation:
A decomposition reaction occurs when one reactant breaks down into two or more products. It can be represented by the general equation: AB → A + B. In this equation, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction
The correct answer is D
According to the law of conservation of mass, mass can not be destroyed or lost, it can just be rearranged in space, turned into energy etc.
Therefore, in our of example the wood was burned and turned into ashes. Even though the ashes weight less than the original wood, some of the solid mass of the wood was converted to gas and energy, so the overall mass remained the same.
