Answer:
6 x (10)^26 electrons.
Explanation:
1 mole = 18 gr
1 gm =1/18 mole
1 kg = 1000/18 mole
Now , 1 mole of any compound = 6.022 x (10)^23 atoms.
Therefore, 1 kg of H20= (1000/18)*(6.022 x (10)^23) atoms
Roughly , 3.34 x (10)^25 molecules
And each molecule has 18 electrons
Therefore, 6 x (10)^26 electrons.
Thank you.
COMPOUND A IS IONIC AND COMPOUND B IS MOLECULAR.
Ionic compounds have some properties which distinguish them from molecular compounds, these include: high boiling point, high melting point and high and their rate of vaporization is low compared to molecular substances. The molecular substance on the other hand have low melting point, low boiling points and they vapourize easily. These differences are due to the strength of the inter molecular forces among the molecules of these substances. The inter molecular forces between the molecules of ionic substances is stronger than that of molecular substances.<span />
Answer:
try "socratic" it's an awesome app!
Explanation:
Answer:
For a positive point charge, the lines radiate <u>outwards</u>, while for a negative point charge, the lines converge<u> inwards.</u>
Explanation:
A single point charges produces an electric field which has a radial shape.The sign of a charge determines the the direction of the field. In Positive charge have the direction of field is out of the charge and for negative charge, the direction of field is towards the charge.This behavior is in relation to how a positive test charge will experience in a field.
