Enter an equation of a chemical reaction and click 'Balance'. The answer will appear below
Always use the upper case for the first character in the element name and the lower case for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - carbon monoxide
To enter an electron into a chemical equation use {-} or e
To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}.
Example: Fe{3+} + I{-} = Fe{2+} + I2
Substitute immutable groups in chemical compounds to avoid ambiguity.
For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced,
but PhC2H5 + O2 = PhOH + CO2 + H2O will
Compound states [like (s) (aq) or (g)] are not required.
If you do not know what products are enter reagents only and click 'Balance'. In many cases a complete equation will be suggested.

What is true about the inertia of two cars, Car A of mass 1,500 kilograms and Car B of mass 2,000 kilograms?
Delicious77 [7]

Answer:

Car B has more inertia than Car A

Explanation:

Given that,

Mass of car A = 1500 kg

Mass of car B = 2000 kg

Inertia is directly proportional to the mass of an object. Inertia is the measure of the mass of an object.

In this case, the mass of car B is more than that of car A, it means the inertia of car B is more than that of car A.

Hence, the correct option is (c) "Car B has more inertia than Car A".

What is an aqueous solution? What is an aqueous solution? An aqueous solution is a homogeneous mixture of a substance with water
mestny [16]

Answer:

The answer to your question is: first option.

Explanation:

What is an aqueous solution?

Aqueous solution is a solution which solvent is water and is homogeneous.

a) An aqueous solution is a homogeneous mixture of a substance with water.  This is the correct definition of aqueous solution because it mentions the characteristics of this kind of solutions.

b) An aqueous solution is a dispersoid solution. This option is wrong, it is a homogeneous solution, and the description do not mention water.

c) An aqueous solution is a mixture of a liquid substances. Aqueous solution is a mixture but one of the components is water not a liquid substance.

d) An aqueous solution is a heterogeneous mixture of a substance with water. Aqueous solution is homogeneous not heterogeneous, this option is wrong.

which of the following is the smallest in volume? nucleus of oxygen atom, water molcule, protron, ice crystal, electron cloud of
Marta_Voda [28]
The only thing you need to put the followings into correct order is to remember that the smalles mass - the less volume it has. So, accordnig to this, the order should be like that : An ice crystal- A water molecule-An oxygen atom-The electron cloud-<span>An oxygen nucleus. Hope you will find it  helpful!</span>
