ANSWER:

ANSWER:

All particles have energy, and the energy varies depending on the temperature the sample of matter is in, which determines if the substance is a SOLID, liquid, or GAS. Solid particles have the least amount of energy, and gas particles have the greatest amount of energy.

The temperature of a substance is a measure of the AVERAGE kinetic energy of the particles. A change in PHASE may occur when the energy of the particles is changed.

There are spaces between particles of matter. The average amount of empty space between molecules gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases.

d) TRUE

Answer:

OSMOTIC pressure is directly proportional to molarity and molarity is dependent on the NUMBER of solute particles and is independent on the nature of the solute particle. Hence osmotic pressure is a COLLIGATIVE PROPERTY.

Answer:

We KNOW APPROPRIATE IDENTITY (x+y+z)2=x2+y2+z2+2xy+2yz+2xz.

=x2+(2y)2+(4z)2+2(x)(2y)+2(2y)(4z)+2(x)(4z)

=x2+4y2+16z2+4xy+16yz+8xz.

Answer:

1 CARBON atoms

Explanation:

HOPE it HELPS you

Answer:

N1V1 = N2V2

N1=?

V1=5

N2=2

V2=84.6

Apply into the equation

N1*5 = 84.6*2

N1 = 84.6*2/5 = 33.84 N

M = 33.84/2 = 16.92 M

16.92 moles of H2SO4 is present in the 1000 ml of the soln.

Density = mass/volume then,

mass = density x volume = 1.8*1000 = 1800g.

hence the mass of H2SO4 =16.92*98 = 1658.16g.

Percentage PURITY of H2SO4 = (1658.16/1800)*100 = 92.12%

THEREFORE the percentage purity for the H2SO4 in the SOLUTION is 92% approximately

Answer:

BRAINLY is the good app but my suggestion is that •others cannot DELETE our answer as well as question •I have one more suggestion that when we ask a question the points were given when we click on 100 the question is of only 50 that means if we ask a question of points 10 the question will be of only 5 points •So, my suggestion is this That if the points of a question 100 so the answerer will also get 100 not 50 or HALF •I hope that you RESPECT my suggestions and change them THANK YOU

MARK ME THE BRAINLIEST !

Answer:

The following (rate depends on ambient conditions- temperature and especially relative humidity):

The pellet begins to ABSORB humidity from the atmosphere.

As it does so, it will gradually deliquesce (soften and dissolve into the absorbed water). If temperatures are below freezing, it will still absorb humidity to a certain point but will not turn liquid. If temperatures are HIGH but very dry (e.g. desert conditions, the same thing will happen. High humidity is the key requirement for it to ACTUALLY become liquid.

During this process, it is continually absorbing carbon dioxide from the atmosphere. This reacts with the water to FORM carbonic acid which immediately reacts with the hydroxide and is converted to sodium carbonate. The process is MUCH slower in the solid phase than the liquid phase. Overall this is a very slow process, such that bulk tanks of 50% sodium hydroxide are normally vented to the atmosphere without any worry of excessive carbonate formation.

Answer:

DUE to very less FORCE of attraction between the molecules.

Answer:

ZINC is more reactive than hydrogen and it displaces hydrogen from dilute acids. Zinc REACTS with dilute sulphuric acid to form zinc SULPHATE and hydrogen gas is evolved. This is a SINGLE displacement reaction of a non-metal by a metal. ... So, this reaction is a chemical change.

Answer:

Zinc reacts with sulfuric acid to produce hydrogen. The REACTION is catalysed by copper. In this practical, STUDENTS can compare the rate of reaction (with and without copper) by means of the rate of PRODUCTION of hydrogen gas bubbles.

This is a quick and easy experiment that can be DONE individually or in pairs.

Answer:

Chemistry has its own LANGUAGE such as symbol, equation, ION, valency, atom, element, molecule, reaction and so on. A chemical symbol denotes in short, a PARTICULAR element or an atom of that element. Chemical reactions are easy to WRITE with chemical symbols than having to write the lengthy chemical names.
