Explanation:
ans: gas
The same number of particles in a gas spread further apart than in the liquid or solid states. The same mass takes up a bigger volume . This means the gas is less dense. Density also depends on the material.
The answer is false. The particles in a suspension are not dissolved into the solvent rather they are suspended or dispersed into the solvent, Suspension is a heterogeneous mixture where solute-like particles settle out of a solvent-like phase. Examples are mercury in shake in oil, oil shake in water, and chalk in water.
Answer;
1) Moleculer solids; I2, S8 and P4 2) Covalent solids; SiO2; 3) Moleculer liquid; H2O 4) Moleculer gas; SO2
Explanation:
In Moleculer compounds the molecules are held together by intermoleculer forces such as van der waals forces and dipole-dipole interaction. They have weak melting and boiling point.
Covelent compounds are held together by covalent bond. They have strong melting and boiling point.
Photosinthisises equation is carbon dioxide + water ⇒ glucose (suger) + water
the light is needed to react with the CO² to create the oxygen needded<span />
Explanation:
The pH is a 1 to 14 scale that measures how acidic or basic is a solution, at lowest number the solution will be acid, in 7 the solution will be neutral, and in higher values will be basic. It is a logarithmic scale, so with each number you move, the acidity or basicity will be increased by a factor of 10. So, lemon juice is more acidic than orange juice by a factor of 100.
