Filtration, Sifting and Decanting

Explanation:

Heterogenous mixtures can be seperated by filtration and sifting (Also known as sieving). Sifting is the process of parting a mixture using a sieve. Sifting is used to separate solid mixtures that contain molecules of varying sizes. Filtration is the process of separating a liquid from an insoluble solid. A common example is using a funnel and a coffee filiter to seperate the liquide from the insoluable solid. Although there are many other methods for filtration. You can also separate mixtures by decantation. Decantation is the process of separating a liquid from a solid/liquid by removing the liquid layer at the top from the layer of solid/liquid below.

its a synthesis

Explanation:

Utiliando las leyes de Newton encontraremos que la aceleración de Ana es -1.6 m/s^2.

La segunda ley de Newton dice que:

F = m*a

Fuerza es igual a masa por aceleración.

La tercera ley de Newton dice que cuando dos objetos interactuan, cadan objeto ejerce una fuerza de igual magnitud pero opuesta direccion en el otro.

Ahora veamos como aplicar esto.

Sabemos que la niña empuja al niño, asumamos que con una fuerza F.

Tendremos entonces la ecuación:

F = 20kg*(2m/s^2) = 40N

Y por la tercer ley de Newton, esta misma fuerza (pero en opuesta dirección) se aplica a la niña, entonces tendremos:

-40N = 25kg*a

-40N/25kg = a = -1.6 m/s²

La aceleración con la que retrosede la niña es -1.6 m/s²

When particles in a solid or liquid move faster they move slightly further

apart and is referred to as Elastic collision

Liquids and gases possess more kinetic energy than solids which is why

there is movement of its atoms in a system. Gas have the highest kinetic

energy and solids have the lowest. When the atoms move ,they collide with

one another which pushes the particles further apart.

The atoms in liquid and gas exhibit vibrational(rotational) motion which brings about movement and collision of the particles.

Answer:When salt is dissolved in fresh water, the density of the water increases because the mass of the water increases.

Explanation:

Answer:

24.30

Explanation:

Multiply the relative abundance by the atomic mass of each isotope, add the results together, and divide by 100. Then round to the correct amount of significant figures.

(78.99 x 23.9850) + (10.00 x 24.9858) + (11.01 x 25.9826)/100

24.30 is the average atomic mass (in amu) of element M.

Atomic mass is the quantity of matter contained in an atom of an element.

Explanation:  You want to use the combined gas law equation (P1*V1)/(n1*T1)=(P2*V2)/(n2*T2). So first cross out what remains constant, so volume(V) and I assume moles (since it was not mentioned as a change). Then you can solve algebraically for the answer!

Hope this helped!

The new pressure will be 139.2 kpa .

According to combined gas law,

[tex]\rm\dfrac{PV}{nT} = R[/tex]

In the Combined Gas Law,if we change either one of the variables the others will also change.

When the moles of the gas is constant , the above equation can be written as ,

[tex]\rm \dfrac{P'V'}{T'}= \dfrac{PV}{T}[/tex]

Given is P = 84kpa , T= 350⁰ C and T' = 350+230=580⁰ C , V=V' , P'=?

So we will substitute the values in the above formula keeping volume constant.

[tex]\rm \dfrac{P'}{T'}= \dfrac{P}{T}[/tex]

[tex]\rm\dfrac{P'}{580}= \dfrac{84}{350}[/tex]

[tex]\rm P' = \dfrac{84\times 580}{350}[/tex]

[tex]\rm P'= 139.2 \;kpa[/tex]

Therefore the new pressure will be 139.2 kpa .

Both theoretical and actual yields would be needed to calculate percent yield.

The percent yield of a reaction is defined as the ratio of the actual yield to that of the theoretical yield. It can be mathematically expressed as:

percent yield = actual yield/theoretical yield x 100%

The actual yield is the amount of a specific product produced from a reaction while the theoretical yield is the stoichiometric amount of the same product.

Answer:

dipole-dipole forces

Explanation:

The important intermolecular force in hydrogen iodide HI is dipole- dipole forces. This force is arising due to the partial charge separation and permanent dipole moment.

There are various intermolecular forces which binds two atoms chemically to form a compound. Ionic bonding, covalent bonding, dipole -dipole force, hydrogen bonding, Van der Waals force etc are some of them.

Dipoles are opposite charges separated by a small distance. Dipole -dipole force is generated between the atoms when they have partial charge separation and this creates a permanent dipole moment.

Hydrogen is an electropositive atom and iodine is slightly electronegative. This difference in electronegativities leads to the bonded electrons more attracted towards iodine result in partial charge separation and dipole-dipole force.

Answer:

As heat is added to solid water, the temperature increases until it reaches 0 °C, the melting point. At this point, the phase change, added heat goes into changing the state from a solid to liquid. Only when this phase change is complete, the temperature can increase.

hope this helps

Heat is responsible for the change of phase from solid to liquid state.

A phase change from solid to liquid occur in a substance by heating of that substance because the bonds present between solid particles can be broken down with the help of heat energy.

When the bond is heat at the temperature on which it is broken down, the solid particles are converted into liquid substance so we can conclude that heat is responsible for the change of phase from solid to liquid state.

From the question given above, the following data were obtained:

Initial volume (V₁) = 4 L

Initial pressure (P₁) = 1 atm

Final temperature (T₂) = 600 K

Final volume (V₂) = 2 L

[tex]\frac{P_{1} V_{1} }{T_{1}} = \frac{P_{2} V_{2}}{T_{2}}\\\\\frac{1 * 4}{300} = \frac{P_{2} * 2}{600} \\\\[/tex]
