An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.
Answer:
Atoms only share electrons in covalent bonds. covalent bonds are only formed between nonmetals. there are two different types of covalent bonds; polar and nonpolar. in a polar covalent bonds electrons are shared unequally because one atom has a stronger force of attraction than the other (EX. H2O). In a nonpolar covalent bond, the electrons are shared equally because they're electronegativity is also equal (EX. Cl2).
Overall, the atoms electronegativity determines the way it shares electrons
If the burner doesn't light after several strikes, turn the gas off at the source. Verify that you are generating sparks when striking the striker, and check that the barrel is all the way down and the needle valve is open by the specified amount. If these check out, the problem may be insufficient gas flow.
<u>Answer:</u> The molecular formula of the compound is
<u>Explanation:</u>
We are given:
Empirical formula of the compound = 
For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.
The equation used to calculate the valency is :

We are given:
Mass of molecular formula = 126 g/mol
Mass of empirical formula = ![12+(2\times 1)]=14g/mol](https://tex.z-dn.net/?f=12%2B%282%5Ctimes%201%29%5D%3D14g%2Fmol)
Putting values in above equation, we get:

Multiplying this valency by the subscript of every element of empirical formula, we get:

Hence, the molecular formula of the compound is
