atomic size? Atomic size is the distance between a nucleus of an atom and it's valence or OUTERMOST shell .Atomic size is a very important CHARACTERISTIC of an atom to understand the reactivity .On this property all other properties can be figure out .Does it increase or decrease down the group.From right to left across a period, metallic character increasesbecause the ATTRACTION between valence electron and the nucleus isweaker, enabling an EASIER loss of electrons. Metallic characterincreases as you move down a group because the atomic size is increasing.

e your answer is --------^_^☜☆☞it is because substance make use of latent heat of fusion to OVERCOME force of attraction between particles of SOLID to change into LIQUID during MELTING and latent heat of vaporization to overcome force of attraction between particles of liquid to change into vapours during boiling point .TQSM mark me as brainliest if I did #disha❤

tion:What MASS of AMMONIA is REQUIRED to produce 75 L of hydrogen gas at 28 °C and 113.5 kPa?

hyExplanation:Arrhenius THEORY, theory, introduced in 1887 by the SWEDISH scientist Svante Arrhenius, that ACIDS are substances that dissociate in water to yield electrically charged atoms or molecules, CALLED IONS, one of which is a hydrogen ion (H+), and that bases ionize in water to yield hydroxide ions (OH−).↫↫↫↫↫ Hope it helps youPlz mark me brainlist ↬↬↬↬↬

gas is a BASE gas and CONCENTRATED H2SO4 is an acid thus cannot dry the gas instead it will REACT to form white fumes of (NH4)2SO4. They would INSTANTLY react and no ammonia would come out.

Changes occurring in nature :- The climate started changing a long time ago due to human activities but we came to know about it in the last century. During the last century, we started NOTICING the climatic change and its effect on human life. We started researching on climate change and came to know that the earth temperature is rising due to a phenomenon called the greenhouse effect. The warming up of earth surface causes many ozone depletion, affect our agriculture, water supply, transportation, and several other problems.Natural Reasons :These include volcanic eruption, solar radiation, tectonic plate movement, orbital variations. Due to these activities, the geographical condition of an area become quite harmful for life to survive. Also, these activities raise the temperature of the earth to a great extent causing an IMBALANCE in nature.Human Reasons :Man due to his need and greed has done many activities that not only harm the ENVIRONMENT but himself too. Many plant and animal SPECIES go extinct due to human activity. Human activities that harm the climate include deforestation, using fossil fuel, industrial WASTE, a different type of pollution and many more. All these things damage the climate and ecosystem very badly. And many species of animals and birds got extinct or on a verge of extinction due to hunting.Effects of climate change :- These climatic changes have a negative impact on the environment. The ocean level is rising, glaciers are melting, CO2 in the air is increasing, forest and wildlife are declining, and water life is also getting disturbed due to climatic changes. Apart from that, it is calculated that if this change keeps on going then many species of plants and animals will get extinct. And there will be a heavy loss to the environment .

It is HYDROGEN. SINCE,in L.H.S It was H4 and on R.H.S it had BECOME H2.

When hydrogen SULFIDE gas is PASSED through lead ACETATE solution , it leads to the formation of BLACK colour precipitate of Lead sulfide

The molecular weight for this compound is 64.07 g/mol. ... Problem #2: A compound is FOUND to CONTAIN 64.80 % carbon, 13.62 % HYDROGEN, and 21.58 ... Problem #3: A compound is found to contain 31.42 % sulfur, 31.35 % oxygen, and 37.23

When the sodium metal react with atmospheric oxygen to give sodium peroxide as a PRODUCT. By the stoichiometry we can say that 2 moles of sodium metal react with 1 mole of oxygen to give 1 mole of sodium peroxide as a product. Hence, the sodium peroxide is formed when sodium absorbs MOISTURE from air..EXPLANATION:When sodium is EXPOSED to moist air it forms a coatin of NaO2 and prevents the further reaction of the metal with air. With water it gives NaOH and H2.

Particles in a: GAS are well separated with no regular ARRANGEMENT. liquid are close TOGETHER with no regular arrangement. SOLID are tightly PACKED, usually in a regular pattern.

..... Oxidation +5 ......... OxidationFor N +5 to +4 Net change = -1 ..........REDUCTION +5 ......... OxidationFor N +5 to +4 Net change = -1 ..........ReductionStep 5 +5 ......... OxidationFor N +5 to +4 Net change = -1 ..........ReductionStep 5Determine a ratio of oxidized to reduced atoms that WOULD yield a net increase in oxidation number equal to the net decrease in oxidation number. +5 ......... OxidationFor N +5 to +4 Net change = -1 ..........ReductionStep 5Determine a ratio of oxidized to reduced atoms that would yield a net increase in oxidation number equal to the net decrease in oxidation number.I atoms would yield a net increase in oxidation number of +5. (FIVE electrons would be lost by five I atoms.). 1 N atom would yield a net decrease of -1. (One N atom would gain three electrons.)number of +5. (five electrons would be lost by five I atoms.). 1 N atom would yield a net decrease of -1. (One N atom would gain three electrons.)Thus the ratio of I atoms to N atoms is 5:1.But we have I2 as a reactant then the ratio becomes 10:1number of +5. (five electrons would be lost by five I atoms.). 1 N atom would yield a net decrease of -1. (One N atom would gain three electrons.)Thus the ratio of I atoms to N atoms is 5:1.But we have I2 as a reactant then the ratio becomes 10:1Step 6number of +5. (five electrons would be lost by five I atoms.). 1 N atom would yield a net decrease of -1. (One N atom would gain three electrons.)Thus the ratio of I atoms to N atoms is 5:1.But we have I2 as a reactant then the ratio becomes 10:1Step 6To get the ratio identified in Step 5, add coefficients to the formulas which contain the elements whose oxidation number is changing.and we will get the balanced equation,and we will get the balanced equation,I2 + 10 HNO3 → 2HIO3 + 10NO2 + 4H2O❥Hope you like my answer. #MissBrainlyPrincess♡
