Answer:

Cadmium has larger atomic radius than sulfur.

Explanation:

Down a period, atomic radii decrease from left to right due to the increase in the number of protons and electrons across a period: when a proton is added the pull of the electrons towards the nucleus is larger, so the size of the atom decreases.

Hence, you can compare the elements that belong to a same period and predict that the atom with lower atomic number (number of protons) will haver larger atomic radius. With that:

Oxygen and fluorine are in the period 3, being oxygen to the left of fluorine, so oxygen is larger than fluorine.

Sulfur and chlorine are in the period 4, being sulfur to the left of chlorine, so sulfur is larger than chlorine.

Now see whan happens down a group. Atomic radius increases from top to bottom within a group due to electron shielding. That permits you to compare the size of the elements in a group:

Fluorine and chlorine are in the same group (17), with chlorine directly below fluorine, so the atomic radius of chlorine is larger than the atomic radius of fluorine.

Sulfur and oxygen are in the same group (16), with sulfur directlly below oxygen, so sulfur the atomic radius of sulfur is larger than the atocmi radius of oxygen.

So far, you can rank the atomic radius of sulfur, chlorine, fluorine, and oxygen, in increasing order as:

O < F < Cl < S, concluding that O, F, and Cl have smaller atomic radius than S.

Cadmiun, Cd, is to the left and below sulfur, so both electron shielding (down a group) and increase of the number of protons (down a period) lead to predict the cadmium has a larger atomic radius than sulfur.

Answer:

radio

Explanation:

Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Radio wave travel faster than gamma wave.

Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave.

There is a relation between energy of wave. frequency of wave, and wavelength of wave

Mathematically,

E=hc/λ

where,

E = energy of electromagnetic wave

h is planks constant having value 6.67×10⁻³⁴js

c is speed of light that is 3×10⁸m/s

λ is the wavelength of electromagnetic wave

Therefore, radio wave travel faster than gamma wave.

When you stir sugar into your tea with a spoon, the tea keeps swirling

even after you take your spoon out.This is first law of motion.

Motion is defined as a phenomenon which is described with respect to change in object's position with respect to time.It is given in terms of displacement,velocity,distance ,acceleration,speed.

Branch of physics which deals with motion of objects without any reference to it's cause is called kinematics while the branch which studies forces and their effects on motion is called as dynamics.

Motion applies to various systems like objects,bodies, matter particles ,radiation ,curvature.There are three laws of motion which are proposed by Newton.Classical mechanics is based on Newton's law of motion.Relativistic  mechanics is based on modern kinematics.

Answer:

mass cannot be created nor destroyed just moved around

Explanation:

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed so it can only be moved around during a chemical reaction

Answer:

The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson. The atomic number of an element is the number of protons in the nucleus of an atom of that element.

Answer:

0.025M

Explanation:

Molarity (M) = number of moles (n) ÷ volume (v)

To find the mole of CaF2, we need to find its molar mass:

Ca= 40g/mol, F=19g/mol

CaF2 = 40 + 19 (2)

40 + 38

= 78g/mol.

Using; mole = mass/molar mass

mole = 7.85/78

mole = 0.1006

mole = 0.101mol

Molarity (M) = number of moles (n) ÷ volume (v)

Volume in Litres = 4025mL/1000

= 4.025L

Molarity (M) = 0.101/4.025

Molarity = 0.025M

Answer:

Volume of nitrogen needed  = 125.5 L

Volume of hydrogen needed = 84.05 L

Explanation:

Given data:

Volume of ammonia produced = 250.0 L

Volume of nitrogen needed = ?

Solution:

Chemical equation:

N₂ + 3H₂  →    2NH₃

Number of moles of ammonia:

PV = nRT

1 atm× 250.0 L = n × 0.0821 amt.L/mol.K × 273K

250.0 atm.L = n × 22.41 amt.L/mol

n = 250.0 atm.L /22.41 amt.L/mol

n = 11.2 mol

Now we will compare the moles of ammonia with nitrogen.

             NH₃          :           N₂

               2             :            1

             11.2            :         1/2×11.2 = 5.6 mol

Volume of nitrogen needed:

PV = nRT

1 atm× V  = 5.6 mol × 0.0821 amt.L/mol.K × 273K

V  = 125.5amt.L/1 atm

V = 125.5 L

2nd)

Given data:

Number of moles of ammonia produced = 2.50 mol

Volume of hydrogen needed = ?

Solution:

Chemical equation:

N₂ + 3H₂  →    2NH₃

Now we will compare the moles of ammonia and hydrogen.

                     NH₃          :          H₂

                       2            :            3

                    2.50         :           3/2×2.50 = 3.75 mol    

Volume of hydrogen:

PV = nRT

1 atm × V = 3.75 mol × 0.0821 amt.L/mol.K × 273K

V = 84.05 amt.L/1 atm

V = 84.05 L

Water and light intensity

Explanation:

In an experiment, the component parts of the experiment usually includes a variable which is of two types- independent variable, dependent variable; a constant and a control.

An independent variable is the part of the experiment the person changes or controls.

The dependent variable is the part of the experiment that changes due to changes being made to the independent variable.

The control group is a part of the experiment in which all variable factors have been kept constant and which is used as a standard to compare with other trials of the experiment.

A constant is the part or factor which do not change and is kept constant during the experiment.

In the experiment conducted by the scientist, the two rows of plant receives the same amount of water and light intensity, therefore, they are both the constants.
