Answer: Uruguay on north on the Atlantic side, Chile and north on the Pacific side. The higher up you go the warmer, so Brazil, Ecuador, and Colombia will be the warmest especially in terms of water temperature.
Any colloid consisting of a solid dispersed in a gas is called a smoke. A liquid dispersed in a gas is referred to as a fog. So the answer would be smoke
You take the grams of CO₂ times Avogadro's number divided by the molar mass.
Answer:
Carbon Dioxide = CO2
Explanation:
The synthesis of Malachite is seen in the chemical formula:
CuSO 4 . 5H2O(aq) + 2NaCO3(aq) --> CuCO 3 Cu(OH) 2 (s) + 2Na 2 SO 4 (aq) + CO 2 (g) + 9H 2 O(l)
The bubbles mentioned in the question hints that our interest is the compounds in their gseous phase (g).
Upon examining the chemical equation, only CO2 is in the gaseous state and hence the only one that can be formed as bubbles,
Answer:
Option-D : They move freely in all directions.
Explanation:
The physical properties of gases are well explained by Kinetic Molecular Theory. The key postulates of this theory are;
1) Composition: Gases are made up of small particles called molecules. The size of these molecules is very small as compared to the distance between molecules, therefore the actual volume of molecules is taken negligible as compared to volume occupied by them.
2) Intermolecular Forces: All the gas molecules present in a container behaves independently because they have no force of interactions between them Hence, the attractive forces are taken negligible or too little.
3) Energies: Gas molecules have greater kinetic energy as compared to solids and liquids. Hence, The gas molecules move randomly. They collide with each other and with the walls of the container which causes pressure.
Conclusion:
Therefore, due to large spaces, no interactions, small sizes and high energies the gas particles move freely and there position is not stationary.
