Answer:
In our solar system, Mercury and Venus are inferior planets: their orbits are entirely inside the Earth's orbit. When seen from the Earth, inferior planets go through phases, like the Moon's. An inferior planet on the same side of the sun as the Earth appears dark and is not easy to see.
Explanation:
yes it is true
Decreasing temperature and increasing pressure
Answer:
Explanation:
Glucose = C6H12O6
oxygen = O2
water = H2O
carbon dioxide = CO2
balanced equation :
<em>C6H12O6 (s) + 6 O2 (g) --------------> 6 CO2 (g) + 6 H2O (g)</em>
Answer:
Silver tarnishes and becomes black when exposed to oxygen:
Diesel fuel burns when it is heated:
Explanation:
Chemical Changes are those changes in which the chemistry at molecular level is changed as the starting material is converted in to a new and different final material. This change takes place with the breaking of old bonds and forming of new bonds respectively.
Silver tarnishes and becomes black when exposed to oxygen:
This is a chemical change as Silver a white and lustrous starting material is being converted into a tarnish black final material. However, Silver doesn't readily react with oxygen at normal conditions. It readily react with Sulfur containing compounds in air and produces black compound as Ag₂S.
Diesel fuel burns when it is heated:
Diesel is a mixture of hydrocarbons ranging approximately from C₁₀H₂₀ to C₁₅H₂₈. When these hydrocarbons are burnt they produces a new materials i.e. CO₂ and H₂O.
C₁₀H₂₀ + 15 O₂ → 10 CO₂ + 10 H₂O
Hence, it is also a chemical reaction.
Answer:
A neutralization reaction between an acid and a base will produce a salt and water. In a neutralization reaction, the acid will produce H+ ions that react to neutralize the OH- ions produced by the base, forming neutral water. ... A weak acid + a strong base in an acid/base neutralization reaction will form a basic salt
