Answer:
The volume of water measured is 10mL
Explanation:
Given;
Mass of mass of beaker and the water = 23.670 g
Mass of empty beaker = 13.712 g
Then, mass of water only = Total mass of of beaker and the water minus Mass of empty beaker
mass of water only = 23.670 g - 13.712 g = 9.958 g
Density = mass/volume
Given density of water = 0.9982071 g/mL
Density of water = Mass of water/ Volume of water
Then, Volume of water = Mass of water/Density of water
Volume of water = 9.958 g/0.9982071 g/mL
Volume of water = 9.975886 mL ≅ 10mL
Therefore, The volume of water measured is 10mL
Answer:
Hydrogen is the smallest chemical element. It has one proton and one electron, making it neutral. However, the ions of hydrogen atom are charged species. Thus, the key difference between hydrogen atom and hydrogen ion is that the hydrogen atom is neutral whereas hydrogen ion carries a charge.
Answer:
The double bond is shown conventionally by two lines joining the atoms. Each line represents one pair of shared electrons. Carbon dioxide, CO2 Ethene, C2H4 Ethene has a double bond between the two carbon atoms. A more sophisticated view of the bonding in ethene
Explanation:
Hey there!
There is 1 mol of Ca atoms in 1 mol of CaSO₄
There is one atom of Ca in each molecule of CaSO₄, so in 6.022 x 10²³ molecules of CaSO⁴ there will be 6.022 x 10²³ atoms of Ca.
Hope this helps!
It is called a sinkhole.
This is used to describe a depression in the ground due to a cave collapse. It can also happen because of acidic water dissolving limestone.
