It is the same amount. For example, Carbon has 4 electrons. Putting those 4 electrons in a Lewis Dot Structure will show that they are not paired, so 4 is the number of bonds Carbon can make.
Mass of water = 20.88 - 16.51
Mass of water = 4.37 g
Percentage water in hydrate = 4.37 / 20.88 x 100
Percentage water inn hydrate = 20.9%
Answer : The property in the wrong column is, base form hydrogen gas with metals
Explanation :
Acid : It is a substance that has ability of donating a proton or hydrogen ion,
.
The properties of an acid are :
- Acids are sour in taste.
- It conduct electricity.
- The texture of an acid solution is sticky.
- It react with carbonates to give salt.
- It changes the color of the litmus paper to red.
- It react with a metal to give compound and hydrogen gas.
Base : It is a substance that has ability of donating hydroxide ion,
.
The properties of an base are :
- Base are bitter in taste.
- It conduct electricity.
- The texture of an base solution is slippery.
- It changes the color of the litmus paper to blue.
- It does not react with a metal.
Hence, from the above information, we conclude that the property in the wrong column is, base form hydrogen gas with metals
.
Answer:
Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. This is the mole ratio of the elements and is represented by subscripts in the empirical formula.
Explanation:
The result is the molecular formula
