Elements listed in vertical columns of the periodic table:

Chemistry
2 answers:
True [87]3 years ago
6 0

Answer: Option (a) is the correct answer.

Explanation:

It is known that chemical properties of an atom depends on the number of electrons in its outermost shell, that is, valence shell.

For example, Na has 1 electrons in its valence shell and K also has 1 valence electron as both Na and K belongs to the same group.

Therefore, vertical columns in the periodic table represent groups and horizontal lines represent period.

Thus, we can conclude that elements listed in vertical columns of the periodic table have similar chemical properties.

Vertical columns are called groups, or families. 

They share similar chemical properties. 

Answer: <span>have similar chemical properties</span>

What is smaller than one cell
mr_godi [17]
The organelles and substances inside the organelles are smaller. On a molecular level a group that are smaller are hadrons, which are the group of particles that consist of protons and neutrons. Even smaller than hadrons are leptons, which consist of neutrinos, electons, and MANY others.

Which statement defines dynamic equilibrium? (5 points)
Shalnov [3]

Answer:

1. A state of balance in which the rates of the forward and reverse reactions are equal.

Explanation:

A dynamic equilibrium is like a cycle, the reactants change to products, but the products also change to reactants keeping the amount of each constant.

2. A state of balance in which the forward reaction stops but reverse reaction continues.

In this statement there isnt a equilibrium. The products will change to reactants until the reaction stops.

3. A state of balance in which the forward reaction continues but reverse reaction stops.

Here the reactants will change to products until the reaction stops.

4. A state of balance in which the forward and reverse reactions stop.

In this case the reaction has stopped.

What mass of H2O is produced by the combustion of 1.00 mol of CH4?
kkurt [141]
CH4 : H2O
1 : 2

number of moles of H2O = 1.00 x 2
number of moles of H2O = 2.00mol

mass = number of moles x molar mass

mass of H2O = 2.00 x (1 + 1 + 16)
mass of H2O = 36g

When designing an engineering solution, certain criteria and constraints must be considered. Criteria are the features of the de
kondor19780726 [428]

Answer:

The criteria listed in order of importance are;

1) To be inflated in the event of a collision in order to protect the occupants of the front of the vehicle

2) To be able to withstand the load of the breaking force of the occupants in the front seat of the vehicle during a collision

3) To be relatively tough so as to resist being torn on impact with a sharp object

The constraints listed in order of importance are;

1) How is the model design able to sense a collision that requires the airbag to be inflated

2) The uncertainty of the load the airbag will withstand upon collision

3) The possible hazard that could be caused by the gas used to inflate the airbag

4) The usage/interaction tendency between the vehicle occupant and the airbag system

Explanation:

In order to produce an effective design, it is important to be able to foresee the possible deficiencies of an idea so as to be able to mitigate the problems before an actual incident happens.

What are atoms made of
fomenos

Atoms are made of subatomic particles known as protons, neutrons, and electrons.

(Small bonus: in order to mimic the technology of replicators like in star trek, you need to mess with protons, neutrons, and electrons) (pls dont report)
