If the cup of water contained hot water. Sugar will dissolve a lot slower if it was in room temperature and even slower if it was in cold water.
a) Group 2 elements have 2 electrons on their outer shell, so they form a 2+ charge.
b) they lose 2 electrons as they are transferred to the non metal.
c)They obtain this charge as when they are made into an ionic compound the 2 electrons on the outer shell are transferred to the non metal, meaning there are 2 more protons that electrons, giving it a positive charge.
hope this helps! :)
Answer:
The total pressure would be 8, 93 atm
Explanation:
We apply Dalton's laws, where for a gaseous mixture, the total pressure (Pt) is the sum of the partial pressures (Px) of the gases that make up the mixture.
Pt= Pxa + Pxb+ Pxc....
Pt=2, 20 atm+ 6, 70 atm+ 0,03 atm= 8, 93 atm
Indium has 49 protons
mass number (# of neutrons and # of protons combined) is 115
115 - 49 = 66
66 neutrons
Answer:
The answer to your question is given below
Explanation:
2,4,4,5-tetramethyl-2-hexene.
To draw the structure of the above compound, we must bear the following in mind:
1. The compound is an alkene i.e it contains carbon to carbon double bond (C=C)
2. The parent name of the compound is hexene i.e it contain 6 carbon atoms.
3. The double is located at carbon 2.
4. The substituent group attached to the compound is methly.
5. There are four methly group attached to the compound of which one is located at carbon 2, two at carbon 4 and one at 5.
With the above information, we can easily draw the structure of the compound.
Please see attached photo for the structure of the compound.
