The energy stored in molecular bonds is called _____.

2 answers:

8 0

Correct answer is chemical energy.

Reason:

For the chemical reactions to occur, energy is to be supplied for breaking and reorganization of bonds. This energy can be in form of heat, light, etc. Since, breaking of bonds results in chemical reactions to occur, t<span>he energy stored in molecular bonds is called Chemical energy.</span>

The chief advantage of the metric system over other system of measurement is that it

kolbaska11 [484]

Answer:

The metric system goes by powers of ten, so it's very easy to measure. That would be the main advantage, measurements of ten. We can also say it's the most used measurement around the world, so all scientists have little to no conversion, but the main answer is probably the first one :)

11.0 L of hydrogen and 5.52 L of oxygen are exploded together in a reaction tube. What volume of water vapor was formed, at STP?

Marysya12 [62]

Answer:

11.0 L

Explanation:

The equation for this reaction is given as;

2H2 + O2 --> 2H2O

2 mol of H2 reacts with 1 mol of O2 to form 2 mol of H2O

At STP;

1 mol = 22.4 L

This means;

44.8 L of H2 reacts with 22.4 L of O2 to form 44.8 L of H2O

In this reaction, the limiting reactant is H2 as O2 is in excess.

The relationship between H2 and H2O;

44.8 L = 44.8 L

11.0 L would produce x

Solving for x;

x = 11 * 44.8 / 44.8

x = 11.0 L

Bromine pentafluoride BrF5 is a good example of inter halogen molecule

Snezhnost [94]

Answer:

a) The lewis dot structure is shown in the image attached to this answer

b) The formal charge on each of the atoms is zero

c) bromine has an oxidation state of +5 while fluorine has an oxidation state of -1

d) 90 degrees

e) Square Pyramidal

f) polar bonds

g) polar molecule

Explanation:

The molecule BrF5 has a formal charge of zero. It exhibits an sp3d2 hybridization state with a square pyramidal geometry. The bond angle in the molecule is 90 degrees. It is a molecule of the type AX5E. The oxidation state of bromine is +5 while that of fluorine is -1.

The Br-F bonds are polar. The overall molecule is polar due to asymmetric charge distribution concentrating on the central atom since the molecule is square pyramidal.
