Interpretation:
The name and describes the two change states of mater should be explain.
Concept Introduction:
Matter: It can exist one of three main states, like solid, liquid and gas, solid matter is composed to tightly packed partials, a solid will becomes it shape, and the partial are not free to move around. Than liquid matter is made of more loosely packed particles, gas molecule completely loosed particles.
Phase changes: The phase changes include vaporization, condensation, melting, freezing, sublimation and deposition. For example vaporization occurs when moved particles of a liquid reach a high enough energy to leave the surface of the liquid and change into the gas state. Then another example the evaporation is a puddle of water draying out.

- Arrange the elements Na, Si, and S in the order of(a) decreasing atomic radius.(h)increasing first ionization energy.arrow_forwardAccording to chemist John Dalton, if one mole of nitrogen is combined with three moles of hydrogen to form one mole of ammonia (knowing that nitrogen, with an atomic number of 7, has an atomic mass of 14, and hydrogen, with an atomic number of 1, has an atomic mass of 1), then this compound will have an atomic weight (or molecular mass) of: 14 grams per mole (14 daltons) 17 grams per mole (17 daltons) 20 grams per mole (20 daltons) 22 grams per mole (22 daltons) 43 grams per mole (43 daltons)arrow_forwardUsing collision theory, indicate which of the following statements regarding physical nature of the reactants is true: a) physical nature of reactants The physical nature of reactants does not influence the rate of reaction because reactions happen only on the molecular level. Solids, liquids or gases all influence the rate of reaction the same because they are all in the physical state. Solid state reactants react faster if the particle sizes are larger because reactions occur at the boundary surface with direct contact. Gaseous-state reactions are faster than liquid-state or solid-state reactions because collisions between reactants are more frequent.arrow_forward

What is the composition of snow? Describe its solid phase and interactions between other particles of snow through intermolecular attractions.arrow_forwardThe atomic number on an element tells us the number ofarrow_forward
- Chlorine is an element with the symbol Cl. Draw and label atomic structure of chlorine indicating the number and locations of protons, neutrons and electrons in one atom of chlorine.arrow_forwardSolid iron(II) fluoride (FeF2, Ksp= 2.36 x 10-6) is dissolved in water. If 8.1 x 10-3 mol L-1 of iron(II) ion is found to be in solution. Is the solution saturated, unsaturated, desaturated or supersaturated.arrow_forwardEthyl mercaptan is an odorous substance added to natural gas to make leaks easily detectable. A sample of ethyl mercaptan weighing 3.17 mg contains 1.64 mg of sulfur. What is the mass percentage of sulfur in the substance?arrow_forward
- Atoms A and B interact to form a compound, AB2. When measured, atom A has a partial negative charge and atom B has a partial positive charge. From this information, we can conclude what? Select only ONE answer choice. Note: - means "approximately equal to" , A > B means "A is greater than B" , and A B: AB2 is hydrophilic Not enough information to answer the questionarrow_forwardWhat is the smallest unit of an element that retains the properties of that element?arrow_forwardThe substance oxygen has the following properties: normal melting point: 54.8 K normal boiling point: 90.2 K triple point: 1.50×10-3 atm, 54.4 K critical point: 49.8 atm, 154.6 K A sample of oxygen is initially at a pressure of 58.9 atm and a temperature of 96.9 K. The pressure on the sample is reduced to 1.50×10-3 atm at a constant temperature of 96.9 K. Which of the following are true?Choose all that apply The sample is initially a liquid. The gas initially present will solidify. The final state of the substance is a gas. One or more phase changes will occur. The final state of the substance is a solid.arrow_forward
