Answer:

La respuesta correcta es: Al aumentar la temperatura se dilata con facilidad

Explanation:

El mercurio (Hg) es un elemento metálico que a temperatura ambiente es un líquido. Tiene la propiedad de dilatarse con facilidad al aumentar la temperatura, propiedad que ha sido utilizada en los termómetros de mercurio. En estos termómetros, el mercurio está dentro de un tubo de vidrio graduado con un bulbo para transmitir el calor. Al estar en contacto con un cuerpo más caliente (a mayor temperatura), el mercurio del interior del termómetro se dilata (expande su volumen) y asciende por el tubo indicando la temperatura correspondiente, graduada en el vidrio.

Answer: The data are consistent with the law of conservation of mass because the mass of reactants equals the mass of products

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Given: mass of sodium = 12.8 g

mass of chlorine = 19.6 g

mass of reactants = mass of sodium + mass of chlorine = 12.8 g + 19.6 g = 32.4 g

Mass of product = Mass of sodium chloride = 32.4 g

As mass of reactant = mass of products , Thus results are in accordance with the law of conservation of mass.​

Answer:

187.34 atm

Explanation:

From the question,

PV = nRT.................. Equation 1

Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.

make P the subject of the equation

P = nRT/V.............. Equation 2

n = mass(m)/molar mass(m')

n = m/m'............... Equation 3

Substitute equation 3 into equation 2

P = (m/m')RT/V............ Equation 4

Given: m = 46 g, T = 25°C = (25+273) = 298 K, V = 3.00 L

Constant: m' = 2 g/mol, R = 0.082 atmL/K.mol

Substitute these values into equation 4

P = (46/2)(0.082×298)/3

P = (23×0.082×298)/3

P = 187.34 atm

Answer:

KCl[tex]_{2}[/tex], >  KBr[tex]_{2}[/tex], > KI[tex]_{2}[/tex]

Explanation:

KBr[tex]_{2}[/tex],   KCl[tex]_{2}[/tex],   KI[tex]_{2}[/tex]

The equilibrium constant for the reaction between Alkene and Halogen to give Alkyl halide as a product

Keq = [tex]\frac{[C2H4X2 ]}{[C2H4 ][ X2]}[/tex]

hence the order of equilibrium from the Largest to the smallest equilibrium

Nonpolar covalent bonds are a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecule.

Answer:

made of different kinds of tissues

Explanation:

cause that's the only one that makes sense because it goes: cell, tissues,organ,organ system , organism

1. the simplest unit of life - cell

2. a individual organ - would be made of different kinds of tissues

3. tissues - would be made of one kind of cell

4- an organ system - meets all the needs of a organism

also it wouldn't make sense for a individual organ to be made of only one kind of cell so yeah

good luck :) I hope this was right

Answer:

2.41 mol

Explanation:

53.9 L x 1 mol/22.4 L = 2.41 mol

the answer is A.

the scientist used mud and vinegar to make a model of the volcano.

Answer:

Given mass 150 kg= 150000 gram

molar mass 71 gram

number of moles = given mass/molar mass

= 2112.76 moles

1 mole = 24 Dm³

2112.76 mole =24×2112.76= 50706.24 Dm³

The volume of the mole of gas at room temperature and pressure is 50,704.08dm³

We need to first calculate the number of moles of Chlorine gas (Cl₂)

Number of moles = Mass/Molar mass

Given the following parameters

The molar mass of Cl₂ = 71g/mol

Mass of chlorine gas = 150kg = 150,000g

Get the number of moles

[tex]n=\frac{150,000}{71}\\n=2,112.67moles\\[/tex]

Given that volume of 1 mole at STP = 24.0dm³

2112.67 moles = x

Get the volume of the chlorine gas at STP.

Volume of Cl₂ at STP = 24 × 2112.67

Volume of Cl₂ at STP = 50,704.08dm³

Hence the volume of the mole of gas at room temperature and pressure is 50,704.08dm³

Answer:

Both graduated cylinders and beakers are pieces of laboratory glassware that have a specific function. Graduated cylinders typically are more accurate at reading the volumes of the liquid inside. Beakers are better for stirring and mixing liquids.

Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck. The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. Beakers are mainly for measuring and transporting liquids from one site to the next.

Answer:

8.334×10^-6 moles

Explanation:

a mole is 6.023×10^23

5.02×10^18 ÷ 6.023×10^23=8.33×10^-6

so there are 8.33×10^-6 moles of water in 5.02x10^18 molecules of water

The number of moles of water in which 5.02 × 10¹⁸ molecules of water is present is 8.33 × 10⁻⁶.

Moles is a unit which is used to tells about the quantity of any substance, in one moles of any substance 6.023 × 10²³ number of atoms of that substances are present.

In 1 mole of water = 6.023 × 10²³ number of molecules of water is present

So, number of 5.02 × 10¹⁸ molecules of water present in how many moles will be calculated as:
Required moles = 5.02 × 10¹⁸ / 6.023 × 10²³ = 8.33 × 10⁻⁶

Hence, required moles is 8.33 × 10⁻⁶.
