How did the study of the atom contribute to our understanding of the periodic table of the elements? (1 point) Atoms are represe

ntative of elements, so scientists scaled up O atomic char- derstand elemental characteristics, allowing sc Highlight e elements in a periodic table. The determination of electron charge led to an understanding of O how atoms interact with one another, which facilitated the organization of the periodic table. Elements are made of atoms, so understanding atoms provided O information about elements, which led to the organization of the periodic table. Experiments that identified characteristics of atoms provided O scientists with atomic weights and atomic numbers, which were used to organize the periodic table.​

The study of the atom contribute d to our understanding of the periodic table of the elements by virtue of the following;

  • Elements are made of atoms, so understanding atoms provided information about elements, which led to the organization of the periodic table

  • Experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the periodic table.

As we know; the periodic table is an array of elements in order of their atomic number.

In which case, the periodic table is made up of 7 rows otherwise called Periods and 8 columns otherwise called Groups.

steposvetlana [31]

Answer:

Average speed of the swimmer is 4.44 m/s

Explanation:

As we know that the speed is the ratio of distance covered over time interval

so here we can say

v = \frac{d}{t}

so we know that

d = 200 m

time taken to complete the trip is

t = 45 s

now we have

v = \frac{200}{45}

v = 4.44 m/s

In nuclear fission and fusion the mass defect is
riadik2000 [5.3K]

Option C

In nuclear fission and fusion the mass defect is the mass lost during the reaction that is converted into energy

<u>Explanation:</u>

Mass defect is the contrast within the estimated mass of the released system and the empirically estimated mass of the nucleus. The nuclear binding energy is acknowledged as mass, and that mass enhances "missing".

This missing mass is described as a mass defect, which is nuclear energy, also acknowledged as the mass discharged from the reaction as any trajectories. The mass defect of a nucleus depicts the mass of the energy adhesive of the nucleus and is the variation amidst the mass of a nucleus and the entirety of the masses of the nucleons of which it is comprised.

A 1.83 kg book is placed on a flat desk. Suppose the coefficient of static friction between the book and the desk is 0.442 and t
fredd [130]

Answer:7.92 N

Explanation:

Given

mass of book m=1.83\ kg

coefficient of static friction \mu _s=0.442

coefficient of kinetic friction \mu _k=0.240

To move the book, one need to overcome  the static friction  

Static friction F_s=\mu _sN

F_s=\mu _s\times 1.83\times 9.8

F_s=0.442\times 1.83\times 9.8

F_s=7.92\ N

After overcoming the Static friction , Force needed to move the block is

F_k=\mu _kN

F_k=0.240\times 1.83\times 9.8

F_k=4.30\ N

 A balloon is 3m in diameter and is filled with 5 kg of N2. Find the specific volume of the gas in the balloon. Express it in bo
enyata [817]

Answer:

The the specific volume and weight are 79.16m³/k mol and 49 N.

Explanation:

Given that,

Diameter = 3 m

Mass of N₂ = 5 kg

We need to calculate the volume of balloon

Using formula of volume

V= \dfrac{4}{3}\pi r^3

V= \dfrac{4}{3}\pi \times{\dfrac{d}{2}}^3

V= \dfrac{4}{3}\pi \times(\dfrac{3}{2})^3

V=14.137\ m^3

We need to calculate the specific volume in the balloon

Specific\ volume=\dfrac{Volume}{mass}

Specific\ volume=\dfrac{14.137}{5}

Specific\ volume=2.8274\ m^3/kg

Now, Molar mass of N₂ gas is 0.028 kg/mol

Now, Specific volume of N₂ gas in the balloon is

Specific\ volume =0.028\times2.8274=0.0791672\ m^3/mol

Specific\ volume =79.16m^3/kmol

(b). We need to calculate the weight of the gas in the balloon

Weight of the balloon is dependent on the mass of the gas.

The weight of the gas is given by

W = mg

W = 5\times9.8

W = 49\ N

Hence, The the specific volume and weight are 79.16m³/k mol and 49 N.
