Answer:
The correct answer is 8 g.
Explanation:
During a physical change, the identity of the substance <u>does not change, because no chemical reaction occurs</u>. So, after the change, the amount of substance is still the same. Examples of physical changes are changes in the state of matter (solid-liquid-gas). If 8 grams of ice (water in the solid-state) are melted, after the melting process we will have 8 grams of water in the liquid-state, but still 8 grams of water.
Answer:
HBr
Explanation:
As per the given options, HBr could be considered the strongest acid and the strength of its bond that makes it the strongest acid. This acid is highly precarious and toxic in comparison to other acids. It is so strong that <u>it can immediately disunite and concedes its protons in suspension</u> later. It is also <em><u>strong as it gets ionized completely in an aqueous solution and also due to the hydronium ions formation on suspension</u></em>. The other compounds do not do so.
Answer:
The given blank can be filled with corona.
Explanation:
The Moon moves in between the Earth and the Sun in a solar eclipse. When this takes place, a segment of the light of the Sun gets blocked. During a total eclipse of the Sun, the corona of the Sun can be witnessed shining in all the orientations surrounding the Moon. The only time when the corona of the Sun can be witnessed is during a total solar eclipse. Colorful lights from the chromosphere of the Sun and the solar prominences are also visible at the time of a total solar eclipse.
The condenser lens, is placed between the light source and the specimen and it gathers and focuses the light rays in the plane of the microscopic field to view the specimen.
