What happens if you mix lithium and aluminum together?

Answer: A.

Explanation:

Brownian motion is the random motion of a particle as a result of collisions with surrounding gaseous molecules. Diffusiophoresis is the movement of a group of particles induced by a concentration gradient. This movement always flows from areas of high concentration to areas of low concentration.

Example:  The movement of pollen grains on still water. Motion of dust motes in a room (though largely influenced by air currents).

Answer:

323.7g

Explanation:

Given parameters:

Number of moles of AgCl = 3 moles

Unknown:

Mass of Ag = ?

Solution:

We solve this problem by working from the known to the unknown;

The known here is AgCl;

    From the balanced equation:

              Zn + 2AgCl → ZnCl₂ + 2Ag    

              2 moles of AgCl will produce 2 moles of Ag

              3 moles of AgCl will produce 3 moles of Ag

The mass of Ag will be;

     Mass of Ag  = number of moles x molar mass

Molar mass of Ag = 107.9g/mol

      Mass of Ag = 3 x 107.9  = 323.7g

You need to find the entropy of fusion in order to find this out.

Answer:

260 g

Explanation:

Data obtained from the question include:

Mole of cobalt (Co) = 4.41 moles

Mass of cobalt (Co) =...?

The mole of a substance is related to its mass according to the following equation:

Mole = mass / Molar mass.

With the above formula, we can obtain the mass of 4.41 moles of cobalt as follow:

Mole of cobalt (Co) = 4.41 moles

Molar mass of cobalt = 59 g/mol

Mass of cobalt (Co) =...?

Mole = mass /Molar

4.41 = mass / 59

Cross multiply

Mass of cobalt = 4.41 × 59

Mass of cobalt = 260 g

Therefore, the mass of 4.41 moles of cobalt is 260 g

Answer: Solids, gases, or liquids

Explanation:

Matter can undergo physical and chemical changes called Phase Changes. Substances are classified based on physical states, often referred to as the States of Matter. At room temperature and pressure the common Physical States of elements are solids, gases or liquids.

Most are solids only 11 are gases and 2 are liquids

The most common physical state of elements in the periodic table is Solids as there are about 84 elements which exists as solids at room temperature and pressure in the periodic table

Elements in the periodic table can exist as one of the prominent physical states at room temperature and pressure.

These physical state may be;

These elements are Hydrogen, Helium, Nitrogen, Oxygen, and the other Noble gases.

During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds. ... Thus water expands as it freezes, and ice floats atop water.

When water molecule freezes, the water molecules have slowed down enough that their attractions fixed them into fixed positions.

The term freezing is defined as a phase transition where a liquid converted into a solid when its temperature is lowered below its freezing point.

The freezing point is the temperature at which a liquid turns solid. In the freezer, for example, water-filled ice cube trays.

Water molecules freeze in a hexagonal pattern, with molecules further apart than when the water was liquid. It is worth noting that the molecules in ice would be vibrating.

Thus, When water freezes, the water molecules slow down to the point where their attractions arrange them into fixed positions.

Answer: B) The energy of the solid increases, and the particles begin to slide past each other.

Explanation:

The energy of the solid matter is required to be increased so that molecules of the solid matter get separated from each other and an transition from solid matter to liquid matter occurs. The liquid components of the matter will slide past each other as they have obtain energy for fluidity. The liquid iron can be molded into any shape and the energy decreases considerably.

Answer: It will sink

Explanation:

To solve this we must be knowing each and every concept related to carbon monoxide. Therefore, carbon monoxide float to the top of the room.

When the carbon in fuels burns inefficiently, a toxic gas known as carbon monoxide is created. It is emitted both naturally—from forest fires or volcanic eruptions, for example—and artificially—through procedures. It is lighter than the air.

By attaching to and removing oxygen from myoglobin, carbon monoxide reduces the oxygen storage capacity in muscle cells, which is another way it upsets the body's processes. If carbon monoxide (CO) leaked into your home, carbon monoxide float to the top of the room. Numerous manufacturing and medicinal items employ carbon monoxide.

Therefore, carbon monoxide float to the top of the room.

Answer:

54.9 g

Explanation:

0.450 mol x 122g/mol

Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate. Therefore, 54.9 g is the mass in grams of 0.450 moles of Sb.

Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope.

Average atomic mass = (mass of first isotope× percent abundance of first isotope)+(mass of second isotope× percent abundance of second isotope)

Mass of  Sb= number of moles of  Sb ×Molar mass of  Sb

=0.450 mol x 122g/mol

=54.9 g

Therefore, 54.9 g  is the mass in grams of 0.450 moles of Sb.

J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons.

Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."

Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.

Based on these results, Rutherford proposed the nuclear model of the atom.

Explanation:

A sea breeze is a phenomenon that occurs during hot summer days when the sun transfers its heat to the earth surface by convection the land absorbs energy much easier than the seawater. As a result, the air above land will become warmer and as we know warmer air is lighter so this air will rise-up the air above the sea will now move from sea to the land to balance this air also there will be heat exchange between land air and the sea air by conduction and hence together they will create a phenomenon called a 'sea breeze'.

100 trillion atoms are in one cell and  so just find how many cells are in a chair and then take 100xthe number and you get your answer

Explanation:

There are uncountable atoms which are present in a chair depending on it's size.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

¡Hola!

En este caso, para el problema descrito, conocemos la corriente de entrada y la de salida del agua, por lo que podemos obtener el flujo de la corriente que contiene el zumo a la salida una vez el agua fue evaporada:

[tex]F_{sol}=11500kg/dia-3000kg/dia=8500 kg/dia[/tex]

Luego, por medio de un balance de zumo de limón en el evaporador en el cual la cantidad que entra es igual a la que sale con sus respectivas concentraciones:

[tex]x_z^{entra}*11500kg/dia=x_z^{sale}*8500kg/dia[/tex]

Como la concentración del zumo a la salida es del 50 % (0.50), la de entrada es:

[tex]x_z^{entra}=\frac{x_z^{sale}*8500kg/dia}{11500kg/dia} =\frac{0.50*8500kg/dia}{11500 kg/dia}\\ \\x_z^{entra}=0.37[/tex]

Que es igual al 37%.

This question is incomplete

Explanation:

The question is incomplete without the options. However, when a metal (in this case what the pennies are made of) is left in direct contact with the heat from the sun, it conducts this heat and becomes hot. This process is called thermal conduction. The thermal energy is readily accepted by the material in which the pennies are made of thereby increasing the thermal energy of the penny coin  which then makes the pennies hot after being left under the sun.
