Answer:
At 3 mmHg and 50°C water exists as a <em><u>gas</u></em>.
Answer : 7.87 X
.
Explanation : To find the fraction of schottky defects in the given lattice of CsCl,
we use the formula,
on solving with the given values ,
and T as 645 + 273 K and rest are the constants.
we get the answer as 7.87 X
.
Cells have limitations, if the cell is stronger it targets other cells , when a cell is weak it possibly mean it’s disease.
Answer: combustion reaction.
Explanation:
Gasoline is a mixture of hydrocarbons (with some other dded substances in minor proportion).
Assuming a hypothetical composition of the gasoline as C₅H₁₂ (only for explanation purposes), the chemical reaction that occurs when gasoline is burned is represented by:
- 2C₅H₁₂ + 16O₂ → 10CO₂ + 12H₂O + energy.
Combustion is a special type of chemical reaction, in which oxygen combines with other substance (element or compound) releasing a large amount of energy in the form of heat and light. It is a very common reaction of the hydrocarbons and the products are carbon dioxide and water in the form of vapor.
The combustion of carbon (C) is a very important and common reaction that has been using to produce energy: C(s) + O₂(g) → CO₂ (g)
Hydrogen is an Alkali Metal side because it has ns1 electron configuration like the alkali metals. elements are very reactive
