6 0

Answer:

Explanation:

1. Weight = 35 P and 45 N = 80

2. Atom: 35P = 35 electrons

3. Bromine

4. It's a non metal. It's in column 17. It will gain 1 electron (normally).

5. Ion: 35 protons, 36 electrons

6. Charge: - 1 usually, but there are exceptions

7. Anions go to the Anode. The anode attracts minus charged elements.

8. In an uncharged state, element 36 would be next. That would be Krypton which is always uncharged. It is a noble gas.

Describe the distribution of mass within an atom

san4es73 [151]

Answer:

The nuclei of most atoms also contain neutrons . The masses of subatomic particles are very tiny. ... Since the nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus. Protons and electrons have electrical charges that are equal and opposite.

Plastics are synthetic, organic polymers. how are plastics similar and different to polysaccharides

yawa3891 [41]

Plastics and polysaccharides are somewhat similar because they are both polymers. Polymers are a long chain of repeating units called monomers. Their difference, however, is the identity of their monomers. Plastics have hydrocarbons as monomers. Plastics with the monomer ethene is called polyethylene. For polysaccharides, their monomers are simple sugars.

Predict how many H1 NMR signals (individual resonances, not counting splitting) are expected for the compound.

Lyrx [107]

Answer:

3 H1 NMR signals

Explanation:

NB: kindly check the diagram of the chemical compound in the attached picture.

This particular Question is based on the part of chemistry which is known as spectroscopy. Spectroscopy is used in the Determination or in identifying chemical compounds. H'NMR works on the principle of nuclear magnetic resonance.

In order to solve this question, one has to count the number of hydrogen in unique location. The diagram in the attached show how hydrogen is been counted.

The numbers of signals is the number of different chemical environments in which hydrogen atoms are located.

NB: signals is also the same as peak in H'NMR.

Hence, the number of H1 NMR signals in this chemical compound is 3.
