Answer:
pH scale
Explanation:
pH scale -
In the field of chemistry , the accurate and exact value of acidity or basicity in a particular solution is calculated with the help of a pH scale .
The scale has reading ranging from 1 to 14 ,
where ,
- If the pH value less than 7 indicates the solution to be acidic in nature ,
- If the pH value is exactly equal to 7 , the solution is neutral in nature ,
and ,
- If the pH value more than 7 indicates the solution to be basic in nature ,
Hence , from the given statement of the question ,
The correct answer is pH scale .

Given
Reaction
2C₄H₁₀ + 13O₂⇒ 8__+ 10H₂O
Required
product compound
Solution
In the combustion of hydrocarbons there can be 2 kinds of products
If there is excess Oxygen, you will get Carbon dioxide(CO₂) and water in the product
If Oxygen is low, you'll get Carbon monoxide(CO) and water
Or in other ways, we can use the principle of the law of conservation of mass which is also related to the number of atoms in the reactants and in the products
if we look at the reaction above, there are C atoms on the left (reactants), so that in the product there will also be C atoms with the same number of C atoms on the left
2C₄H₁₀ + 13O₂⇒ 8CO₂+ 10H₂O
Planck suggested that light/energy was absorbed/released in certain amounts, called quanta.
Answer:
Temperature gets cooler and precipitation increases.
Explanation:
As average temperatures at the Earth's surface rise, more evaporation occurs, which, in turn, increases overall precipitation. … In addition, higher temperatures lead to more evaporation, so increased precipitation will not necessarily increase the amount of water available for drinking, irrigation, and industry
Higher elevations cause temperatures to drop because the higher up in the atmosphere you go, the colder it gets due to air pressure, in turn causing precipitation to freeze, creating snow. Lower elevations are a lot warmer because the air pressure is not as pressurized causing the temperature to be warmer
