Answer: in order of increasing atomic number.

Explanation: Elements in the same group have similar chemical properties. This is because they have the same number of outer electrons and the same valency.

Answer:

What pattern do you see?

Chemical families have the same number of valence electrons.

Make a rule: Based on your data, how are elements arranged into chemical families?

They are arranged vertically depending on how many valence electrons they have, if they have the same amount, they will have the same chemical family in each column.

For the reaction 2A + 4B ----> 2C + 2D, at a particular instant in time, the rate of the reaction is 0.0352 M/s. What is the
viva [34]

Explanation:

The given chemical equation is:

2A + 4B -> 2C + 2D

The rate of the reaction is 0.0352 M/s.

During the course of the reaction, the rate of reactants decreases, and the rate of products increases.

The rate of disappearance of B is shown below:

rate=-\frac{1}{4} \frac{d[B]}{dt}

So, rate of change of B is :

rate of change of B =- rate * 4\\=-0.0352 M/s * 4\\=-0.1408M/s\\\\=-0.141M/s

Option C.

Is freezing depression dependent on having a salt solute, or can non-ionic particles also have an affect on the freezing point o
luda_lava [24]

Answer:

It is not dependent on the salt solute at all but the solute does have an affect.

Explanation:

in the equation you maybe aware of the I factor which represents the ions present in the solution. a non ionic will always have a I value of 1 a ionic can be 2 like in NaCl. What this means that all non ionic will lower the temperature  depression but ionics will have a greater affect because for example salt breaks into Na and Cl will essentially hae more impurities than glucose which doesnt dissociate and will have a I value of 1

Is bread a molecule or a compound
Papessa [141]

Answer:

Bread is a Molecule.

Explanation:

This is what I found.

Bread cannot be classified as a compound. Compounds are formed when two or more substances are bonded together chemically, however, mixtures are not chemically bonded.

The chemical building blocks of bread are proteins and starch. Starch molecules are long, chained polymers of simple sugars (such as glucose) joined end to end by chemical bonds. Proteins on the other hand are more complex, made up of varying combinations of different amino acids.

Hope this helps.
