Explanation:
C. When temperature increase, particles’ speed is suppose to increase. It comes from the ideal gas law.
Answer:
3.83%
Explanation:
First, find the average of the measured value. You should get 286.
291 + 287 + 295 + 281 = 1154
1154/4 = 288.5
Subtract the accepted value (300) from the average measured value (286). Take the absolute value of your answer. You should get 14.
288.5 - 300 = -11.5 = 11.5
Divide the difference from the above problem (14) by the accepted value (300). You should get 0.0467.
11.5/300 = 0.0383
Multiply by 100%.
0.0383 × 100% = 3.83%
The percent error is 3.83%.
Answer:
In diamond the carbon atoms are covalently bonded as flat sheets
In silicon(IV) dioxide the silicon and oxygen atoms are covalently bonded in flat sheets
The structure of copper includes a lattice of positive ions
Explanation:
Diamond and silicon(IV) dioxide are covalent network solids. Covalent network solids are made up of atoms joined to one another by covalent bonds to form a giant lattice, The solids are hard and have a very high melting point. They do not conduct electricity. So, for both diamond and SiO2, atoms are covalently bonded to yield flat sheets in a covalent bonded network solid.
Copper is a metallic substance having metallic bonds, a metallic crystal consists of positive ions and a cloud of electrons.
