Answer:Two more hydrogen atoms will be required
Explanation:
A carbon atom has 4 valence electrons in its outermost shell,thus it can form 4 covalent bonds.Two pairs of electrons are shared in a double bond between C-C atom.two more electrons are left which is shared with two hydrogen atoms.
Answer:
Option 2 and 4 are correct
Explanation:
The reactants in the attached image have more enthalpy and hence less stability as they are more reactive. Thus, Product is more stable than the reactants.
This is an addition reaction in which two reactants add up to form the product.
Very less activation energy is required as the reactants themselves are unstable, possess high energy and hence are very reactive.
Reactants have more energy than the products.
Well, an independent variable ids the thing that stays the same and a dependent variable is the thing that changes.
Answer:
239.45 K
Explanation:
Ideal gas law formula is P1V1T2=P2V2T1
Rearrange that to get...
T2=T1P2V2/P1V1
Fill in the values and solve.
