What is observation in simple words? Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity. […]

What type of volcano has the least violent eruption? Strombolian What is the largest Pyroclast? Pumice is ground up and used today in soaps, abrasive cleansers, and also in polishes. Bombs and blocks are the largest of the pyroclasts. Blocks are angular chunks of rock that has been ejected from a volcano during an eruption. […]

WHAT IS elements and compounds with example? Elements, mixtures and compounds Common examples include carbon, sulfur, oxygen, iron, copper, aluminium. Elements are represented by symbols. Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction. What are the types of compounds? Types of […]

What are the general applications of spectroscopy? Spectroscopy also provides a precise analytical method for finding the constituents in material having unknown chemical composition. In a typical spectroscopic analysis, a concentration of a few parts per million of a trace element in a material can be detected through its emission spectrum. What are spectrometric methods? […]

What 3 things do all forces need? If something is doing one of these four things there must be a net force acting upon it….What can forces do? Make it speed up – accelerate. Make it slow down – decelerate. Change its direction. Change its shape. Is push or pull an unbalanced force? Unbalanced forces […]

Is Q zero in an isothermal process? For an isothermal reaction, the change will happen slowly enough to enable the system go back to the initial temperature by heat exchange(q), so q can never be zero in this process. Is an isothermal change an ideal gas obeys? In an isothermal change, an ideal gas obeys […]

Why we should not buy south facing house? South facing door brings in sharp energy which disturbs positive energy field of the house. That is why in Japan, Geisha houses are always facing west. North West facing door is not so bad. It can bring in health, wealth and prosperity if supported by other vastu […]

What is the correct pathway of the oxygen that we breathe in? The oxygen you breathe in goes into your lungs and passes into your blood from there. It is then transported to all the cells in your body through your bloodstream. The lungs are located in the chest region, protected by the ribs in […]

What is the sum of the forces? The sum of all the forces acting on an object is the net force or resultant force. If all the forces cancel out, the resultant force is zero, else, the unbalanced force will cause acceleration of the object. Force is a vector and hence has both a direction […]

How do you convert atoms to milligrams? 1 Answer Convert the mass of the sample from milligrams to grams. Convert the sample from grams to moles by using neon’s molar mass. Convert the number of moles to number of atoms by using Avogadro’s numebr. How many atoms are in a mol? Avogadro’s Number and the […]
