When sulfur reacts with magnesium it forms magnesium sulfide,he chage on the sulfur atom in magnesium sulfide is -2
Explanation:
This is a neutral beryllium atom
The compound's molecular formula is C6H6
Answer:
FALSE
Since 0.385 < 0.526, the value for week 3 is accepted.
Explanation:
Qexp = (|Xq - Xₙ₋₁|)/w
where Xq is the suspected outlier; Xₙ₋₁ is the next nearest data point; w is the range of data
First, the data are arranged in decreasing order, from highest to lowest:
3. 5.6
2. 5.1
8. 5.1
1. 4.9
6. 4.9
5. 4.7
7. 4.5
4. 4.3
Xq = 5.6; Xₙ₋₁ = 5.1; w = 5.6 - 4.3 = 1.3
Qexp = (|5.6 - 5.1|)/1.3 = 0.385
From tables, at 95% confidence level, for n = 8, Qcrit = 0.526
Since 0.385 < 0.526, the value for week 3 is accepted.
Answer:
leave little space between the molecules.
Explanation:
Matter is made up of small particles called molecules. These molecules present in matter are arranged inside its bulk.
In liquids and solids, the molecules are arranged very close together in such a way that there is only a little space between them. This is why liquids and solids are referred to as "condensed phases".
They are quite unlike gases where there is a lot of space between gas molecules.
