Answer:
difference in the atoms' electronegativites
Explanation:
The measure of an atom's ability to attract electrons is called electronegativity. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. Electronegativity increases from left to right across a row in the periodic table while electronegativity decreases down the group because the bonding pair of electrons is increasingly distant from the attraction of the nucleus. A small electronegativity difference leads to a polar covalent bond. A large electronegativity difference leads to an ionic bond.
To find the electronegativity difference between two atoms, subtract the smaller electronegativity from the larger one to find the difference.
1. If the difference is below about 0.5, the bond is nonpolar covalent
2. If the difference is between 0.5-1.6, the bond is polar covalent.
3. If the difference is over 2.0, the bond is ionic.
4. If the difference is between 1.6-2.0, check for a metal. If there is a metal in the bond, the bond is ionic. If there are only non-metals, the bond is polar covalent.
Answer:
The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.Time itself is slowing down and speeding up because of the relativistic way in which mass warps space and time.
Answer:
D. 90km/hr due West
Explanation:
Given parameters:
Displacement = 1215km
Time = 13.5hr
Unknown:
Velocity = ?
Solution:
Velocity is the displacement divided by the time taken;
Velocity = 
= 
= 90km/hr
Velocity is 90km/hr due West
Breaker D cuz it says 18 and that’s the highest temp
Answer:
As a body moving upward
T=real weight + apparent weight
T=550+490
T=1040
hope u will get the answer:)
