Explanation:

The energy increases (temp increases)....the molecules become further apart and the liquid expands up the graduated scale of the  thermometer to show temp

Answer:

Across a row, atomic radii decreases.

Explanation:

It decreases because nuclear charge increases across a row, electrons are added to the same shell and shielding remains constant. Therefore the outer electrons are more attracted to the nucleus making the atom smaller.

The required volume of sample of neon occupy at these conditions of temperature and pressure is 25.2L.

Mass (W) in grams of helium gas will be converted into moles (n) by using the below equation:

n = W/M, where

M = molar mass = 4g/mol

n = 12g / 4g/mol = 3 mol

n = 24g / 4g/mol = 6 mol

And for this question as pressure and temperature for both the conditions is constant so ideal gas equation becomes:

V₁/n₁ = V₂/n₂, where

V₁ = initial volume = 12.6 L

n₁ = initial moles = 3 mol

V₂ = final volume = ?

n₂ = final moles = 6 mol

On putting these values, we get

V₂ = (12.6)(6) / (3) = 25.2 L

Hence required volume of neon gas is 25.2 L.

Radiation can harm the DNA in our cells. Excessive doses of radiation can motivate Acute Radiation Syndrome (ARS) or Cutaneous Radiation accidents (CRI). High doses of radiation could also cause most cancers later in life.

Radiation is a mutagen, which finally can lead to cancer. Radiation can either kill cells or harm the DNA within them, which damages their capacity to reproduce and might in the end cause cancer. whilst radiation is a gift, excessive electricity debris bypasses your body.

The largest mass silver chloride is precipitated when excess silver ions are added to 30.0cm3 of 0.30M iron(III) chloride solution.

A precipitation reaction is a reaction in which an insoluble substance is obtained when two solutions are mixed together as a result of one of the products of the reaction being insoluble in water.

Silver chloride is an insoluble salt that will precipitate when a single silver salt is added to a soluble chloride salt.

In the above, the largest mass silver chloride is precipitated when excess silver ions are added to 30.0cm3 of 0.30M iron(III) chloride solution since iron (iii) chloride is a weak electrolyte.

The mass percentage of water (H₂O) in cadmium chloride tetra hydratesolution is equal to the 28.2%.

Mass percentage of any substabce present in any solution will be calculated as:
Mass percent = (Mass of substance/Total mass of solution)×100%

According to the question,

Mass of water (H₂O) = 18.02 g/mol

Mass of solvent (CdCl₂.4H₂O) = 183.32 + 4(18.02) = 255.4 g/mol

On putting values, we get

Mass percent = (18.02 / 255.4) × 100% = 28.2%

Hence mass percent of water is 28.2%.

Answer:

precipitation means water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.

Count the number of species that are bonded to chromium in this complex ion. There are four ammonia molecules and two chlorine atoms bonded to chromium. This yields a coordination number of 6.

The co-ordination number of chromium ion in complex [Cr(NH₃)₄Cl₂][tex]^+[/tex] is six as there are four ammonia molecules and 2 chlorine molecules bonded to chromium which gives total co-ordination number of 6.

An ion is defined as an atom or a molecule which has a net electrical charge. There are 2 types of ions :1) cation 2) anion . The cation is the positively charged ion and anion is the negatively charged ion . As they are oppositely charged they attract each resulting in the formation of ionic bond.

Ions consisting of single atom are mono-atomic ions while which consists of two or more ions are called as poly-atomic ions . They are created by chemical interactions . They are very reactive in their gaseous state and rapidly react with oppositely charged ions resulting in neutral molecules.

When vapor pressure reaches an equivalent value to the surrounding air pressure, the liquid(in this case water) will boil. When at sea level, vapor pressure is equal to the atmospheric pressure which is at 100 degrees celsius. Water has a high boiling point because water requires more energy to break its hydrogen bonds before it can boil to high.

The second law of thermodynamics states, in part, that "every spontaneous activity in any isolated system always leads in a rise in the entropy of that system." Because the universe is an isolated system, this assertion may be represented mathematically as follows: (1.6-2)

Divergent boundaries and convergent boundaries are the opposite processes that occurs in the tectonic plates.

Divergent boundaries are the regions where new crust is formed when the plates pull away from each other while on the other hand, Convergent boundaries are the regions where crust is destroyed when one plate dives over another.

So we can conclude that Divergent boundaries and convergent boundaries are the opposite processes that occurs in the tectonic plates.

Fission is the formation of two smaller atoms by the collision of the neutrons. The quantity of energy produced per gram is 7.23 × 10¹⁰ J/g.

Nuclear fission is a process in which the neutron collides with the atom and results in the formation of two isotopes.

The nuclear fission reaction is shown as,

[tex]\rm ^{235}_{92}U + ^{1}_{0} n \rightarrow ^{144}_{54} Xe + ^{90}_{38}Sr + 2^{1}_{0}n[/tex]
