Pls help I don’t understand: Which of these is a balanced chemical reaction?

Chemistry
1 answer:
nata0808 [166]3 years ago
3 0

Answer:

C) 2CO + O₂ →   2CO₂

Explanation:

The equation C is correct.

2CO + O₂ →   2CO₂

This equation have four oxygen atom and two carbon atoms on both side of equation. So it is correctly balanced.

All others are incorrect:

A) CO + O₂ →   CO₂

this is incorrect because there are three oxygen atoms on left while two atoms on right.

B) CO + 2O₂ →   2CO₂

this is incorrect because there are five oxygen atoms on left while four atoms on right.

D)  2CO + 2O₂ →   2CO₂

this is incorrect because there are six oxygen atoms on left while four atoms on right.

Develop a demonstration to show how weight is not the same thing as mass
maksim [4K]

Answer with Explanation:

"Mass" and "weight" should never be used interchangeably with each other. Mass refers to the <u>total amount of matter</u><u> that can be measured in an object, </u>while weight refers to the<u> measure of the</u><u> force of gravity</u><u> that is acting on the object's mass.</u>

The mass of an object is<u> constant</u> (meaning, it doesn't change even if the object will be placed on another location) while the weight of an object relies on the <em>force of gravity.</em> So, this means that your mass on Earth and on the moon are identical, however, your weight on Earth and on the Moon are different. You will weigh lesser on the Moon because it has a lesser surface gravity than that of Earth.

So, this explains the answer.

Which type of intermolecular attractive force operates between (part A) all molecules, (part B) polar molecules, (part C) the hy
nydimaria [60]

Answer:

PART A: The LDF occurs between all molecules. Dispersion forces result from shifting electron clouds, which cause weak, temporary dipole.

PART B: Dipole dipole operates only between polar molecules. This is when two polar molecules get near each other and the positively charged portion of the molecule is attracted to the negatively charged portion of another molecule.

PART C: Dipole dipole and in some cases hydrogen bonding operate between the hydrogen atom of a polar bond and a nearby small electronegative atom. Only if the atom bonded to it were F, O or N it would be hydrogen bonding. Otherwise it is dipole dipole.

What are 2 ways to give an object potential energy?
natita [175]
There are several ways to give an object potential energy. One can move the object against the force of gravity to increase. One can also stretch an object out or put pressure on it.

When a new bond forms in a chemical reaction, what happens?
Kisachek [45]
The answer to this question would be A. Energy is released. 

When a chemical bond is a form, the bond will either suck up energy or produce energy. So, to be precise the energy is not always released but also can be absorbed. In this case, the energy released number will be a minus.

Options B and C is definitely wrong since the bond is formed by an electron, it won't affects neutron/proton.
Option D might be true since the product is made of 2 or more atoms then it would seem larger. But the size of the actual atom won't be increased.
