Answer: NO2.
You can predict that two atoms with similar electronegativity will form covalent compounds while atoms with pretty different electronegativity will form ionic compounds.
Given that N and O are neighbors on the periodic table, you can predict they have similar electronegativities.
Also you can predict that from the fact that N and O are nonmetals, which also means that they will form covalent compounds.
The other compounds liste are formed by metals and non metals wich is an indication that they will have, at least, some ionic character.
Ergo, N and O will form covalent compounds, in this case NO2.
Answer:
The percent error of student is -5 %.
Explanation:
Given data:
measured value = 9.31 m/s²
actual value = 9.8 m/s²
percent error = ?
Formula:
% error = (measured value - actual value / actual value ) × 100
% error = (9.31 m/s² - 9.8 m/s² / 9.8 m/s²) × 100
% error = (-0.49 m/s² / 9.8 m/s²) × 100
% error = -0.05 × 100
% error = -5
V=LW/H
VH=LW
H=LW/V
That’s the answer
Answer:
CaF2 > Ag2CO3 > Ag3(PO4)2 > Ba3(PO4)2
Explanation:
Ksp which is solubility product konstant shows equilibrium between a solids and its respective ions in a solution. And the lower it is the less soluble the ion compound will be. And for CaF2 we have the highest konstant and for Ba3(PO4)2 we have it the lowest.
Answer:
They also showed the effects of pressure on volume if temperature stayed the same
Explanation:
They also showed the effects of pressure on volume if temperature stayed the same is the experiment that will provide an evidence for Boyle's law.
Boyle's law states that "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".
- The law is an affirmation of what happens when there is a dynamics between pressure and volume if temperature is made constant.
- So the experiment designed to investigate this proves and shows Boyle's law.
