Answer:
Q1: Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Q2: Mass is how much stuff something is made of. Volume is how much space an object takes up.
Answer:
C. Moon, Earth, Jupiter, Sun
Explanation:
Well, the moon is smaller than the Earth so, C is the only logical explanation
Answer:
Explanation:
Base your answer to the question on the information below and on your knowledge of chemistry. At 1023 K and 1 atm, a 3.00-gram sample of SnO2(s) (gram formula mass = 151 g/mol) reacts with hydrogen gas to produce tin and water, as shown in the balanced equation below. SnO2(s) + 2H2(g) → Sn(L) + 2H2O(g) Show a numerical setup for calculating the number of moles of SnO2(s) in the 3.00-gram sample.
