Protons and neutrons are located at the nucleus.
Electrons are located on the outer shells, or orbitals.
Subatomic Particles are located inside of the atoms. Protons, neutrons, and electrons.
Answer:
The answer to your question is: 10.67 g/ml
Explanation:
graduated cylinder mass empty= 50 g
+ 30 ml of water = 120 g
+ a rock the level rises 75 ml total mass = 250 gr
density of metal = ?
Formula
density = mass / volume
Process
mass of water = 120 - 50 = 70 g
volume of rock = 75 ml
mass of the rock = 250 - 50 - 120 = 80 g
density of rock = 80 / 75 = 10.67 g/ml
Answer:
none of these are technically correct, but C. is closest? the energy from the sun is radiation, which does not need molecules to travel so its actually B. and C. together? poorly worded
Answer:
The different magnetic shielding effects of the carbonyl double bond in CH0, the CH₂ (a) and CH₂ (b) protons show different chemical shifts
Because the degree of shielding depends on electron density round the proton, the neighboring carbonyl group will increase this density in geranial form.
Now in CH₂ the electron density is increased around CH₂ (a) protons in neral form due to the carbonyl group, and thus it has a lower z values than the corresponding geranial form.
In the case of CH₃ (b) protons. thus they have lower z values and higher chemical shift than the corresponding nera form.
Explanation:
Solution
Due to the different magnetic shielding effects of the carbonyl double bond in CH0, the CH₂ (a) and CH₂ (b) protons show different chemical shifts.
Since the degree of shielding depends on electron density round the proton, the neighboring carbonyl group will increase this density in geranial form more in case of CH₃ (b) protons. thus they have lower z values and higher chemical shift than the equivalent nera form.
Similarly, the electron density is increased around CH₂ (a) protons in neral form due to the carbonyl group, and thus it has a lower z values than the equivalent geranial form.
Answer:
k
Explanation:
They must obey the Law of Conservation of Mass that states that matter cannot be created or destroyed, it is conserved. Atoms are never lost or gained in chemical reactions, they are rearranged. The mass of the reactants must equal the mass of the products.
