O→2NaOH+H2Explanation:You have to count the number of atoms in both sides of the reaction to be equal, to make it a little easier you can make a list. So in the equation Na+H2O→NAOH+H2 , there are1−Na−12−H−31−O−1So you multiply NaOH and H2O by 2, so you have 4 HYDROGENS in both sides, and then multiply Na by 2 to be equal to the NaOH you previously MULTIPLIED.

the rate of diffusion is FASTER in hot TEMPERATURE as compared to low temperature. an activity to illustrate it is the smell of hot SIZZLING food reaches to you from distance but for smell of cold food you have to GO close Explanation:

Here is your ANSWER LEARNER. 1.) Particles of gas have negligible INTERMOLECULAR forces. They move randomly in any direction. Hence when gas is pumped in a vessel, it's particle moves randomly and fills the vessel COMPLETELY 2.) As the particles of gas moves randomly, they bump each other. The particles hits the wall of the CONTAINER with some amount of force. Hence, the gas exerts pressure on the walls of the container.3.) A wooden table fulfills all the properties of solid. A wooden table has a fixed shape and volume. They are incompressible and rigid. Hence, a wooden table should be considered as a solid.I hope this helps you to sort your issue.

Carbon materials are predominantly composed of carbon ATOMS, only the single element, but they have WIDELY diverse structures and PROPERTIES. Diamond has a three-dimensional structure, GRAPHITE has a two-dimensional nature, while carbon nanotubes are one-dimensional, and BUCKMINSTERFULLERENE, C60, is zero-dimensiona

Water has the highest boiling point. In group 15 (NITROGEN family) as we move down the group metallic bonding increases THEREBY INCREASING. But NH3 has more boiling point than phosphine and Arsenic Hydride due to its high ELECTRONEGATIVITY.

3-bromo-3-chlorohexane

Electronic configuration of SODIUM is 2,8,1.So sodium donates its one ELECTRON which is present in outermost shell.So it has VALENCY of 1+.

the ANSWER is PHOSPHATE

is manufactured by reacting ethene with STEAM. The catalyst used is solid silicon dioxide coated with phosphoric(V) ACID. The reaction is reversible. Only 5% of the ethene is converted into ethanol at each pass through the reactor.i hope that this may help u mate PLZ try to make my answer a BRAINLIEST one as it helps me a lot

In copper SULPHIDES: Cu : S mass ratio is 66.6 : 33.4 In SULPHUR trioxide: O : S O:S mass ratio is 60:40 Now in CuS: 33.4 parts of sulphur combines with 66.6 parts of Cu.40.0 parts of sulphur combines with 66.6 x 40/33.4 = 79.8 parts of Cu.Now the ratio of masses of Cu and O which combines with same mass 40 parts of sulphur SEPARATELY is 79.8:60 …1 Cu : O ratio by mass in CuO is 79.9: 20.1 …2Which is simple WHOLE NUMBER ratio hence law of reciprocal proportion is proved.Hope this will help you

3) 4.4 × 10^-19 JExplanation:Given, The ENERGY of photon STRIKING the metallic SURFACE is 5.6 x 10^-19 J. The kinetic energy of the ejected electrons is 12.0 x 10^-20 J.Work function = Energy of photon - K.E(electrons) = 5.6 × 10^-19 - 1.2 × 10^-19 = 4.4 × 10^-19 J

When an aqueous solution of potassium chloride(KCl) when mixed with SILVER nitrate(AGNO3) solution an insoluble white substance  formed is silver chloride(AgCl).The chemical reaction are as follows :KCl(aq) + AgNO3(aq) → KNO3(aq) + AgCl (s).It is an example of  double displacement reaction.In displacement reaction TWO compounds reacts by exchange of ions to form two new compounds.This reaction usually occurs in solution and one of the PRODUCT being in soluble precipitates out as a solid. A precipitate is insoluble product formed during the reaction of two ionic compounds in aqueous solution.This is an example of precipitation reaction also because a white precipitate of silver chloride is formed.Explanation:

hy dude ur answer is Explanation:Temperature: Higher temperatures INCREASE the energy and therefore the movement of the molecules, increasing the rate of diffusion. LOWER temperatures decrease the energy of the molecules, thus DECREASING the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreaseshope it HELPS U

Before air is liquefied, water vapor and carbon dioxide are removed, because these substances SOLIDIFY when cooled and WOULD clog the pipes of the air liquefaction plant. The cooled, compressed air is then allowed to expand RAPIDLY. The rapid expansion causes the air to become cold, so cold that some of it CONDENSES.
