Answer:
–2
Explanation:
Data obtained from the question:
Number of electron = 16
Valence electron = 6
Now, let us write the electronic configuration for sulphur. This is illustrated below:
1s2 2s22p6 3s23p4
From the above, we can see that sulphur will be needing 2 extra electrons to complete its octet configuration. Therefore, the oxidation number of the sulphur will be –2.
The minus sign indicate that the sulphur will accept 2 electrons to complete its octet configuration
Answer:
4 significant figures.
Explanation:
The given measurement have four significant figures 1234.
All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.
Zero between the non zero digits are consider significant like 104 consist of three significant figures.
The zeros at the right side e.g 2400 are also significant. There are four significant figures are present.
1. Particles in gas can MOVE AROUND QUICKLY
2. When you remove energy from particles they move SLOWER and the matter CONTRASTS
<span>I would say only if one of your data points is the origin. But your experiment could have started with a non-zero velocity, for instance, which would rule out the origin as one of your data points. Even so, a "best fit" is not meant to be perfect, it is only meant to be the best that you can do with your particular data set.</span>
Answer:
chloroplast, more precisely in the stroma of the chloroplast
Explanation:
Chloroplasts are a type of chromoplasts that are located in photosynthetic plant cells and green algae.
They can be moved by amoeboid and contractile movements, and placed in the part of the cell that receives the most light. Photosynthetic algae usually have a large chloroplast, but plant cells have a few tens.
The internal medium of the chloroplast is called stroma, and it is composed of a solution of carbohydrates, lipids, protids, nucleic acids, pigments, nucleotides, salts and elements.
Its main function is to capture the light energy and use it in the synthesis of organic matter.
