Answer:

Energy can neither be created not be destroyed

Mass too can neither be created nor be destroyed

Both of them remain conserved during any chemical or physical reaction

Some part of them gets transformed to undesired useless form

Hence law of conservation of mass should better be called the law of conservation of mass and energy

Explanation:

Knowing the mass and volume of an object allows the calculation of its density. Density is defined as the mass divided by the volume of the object. The general physical law relating to floating objects is known as Archimedes' Principle.

The three most fundamental characteristics of an object are mass, volume, and density. Volume indicates something's size, mass indicates how heavy it is, and density is calculated as mass divided by volume.

Mass divided by volume is how density is calculated. It is clear that the relationship between density and volume is inverse. This implies that the density will decrease if the mass of a body remains constant while its volume rises. In contrast, if the volume decreases, density will rise while the mass stays the same.

If the mass or volume of an object is altered, the density of the thing may also change. Water, for example, has a specific density.

The elements are placed in groups and periods on the contemporary periodic table, according to this definition. The elements are organized in the current periodic table in order of increasing atomic number. This periodic table has 7 periods and 18 groupings. Horizontal rows form the arrangement of the periods.

Chemistry is the branch of science that examines the characteristics, make-up, and structure of substances (specified as elements and compounds), as well as the changes they go through and the energy released or absorbed. Every substance, whether created through natural processes or through man made means, is made up of one or more of the roughly a hundred types of atoms that have been classified as elements.

The density of the metal including absolute uncertainty is ρ = 0.48 g/cm³ ± 0.03 g/cm³

The density of the material is the mass/volume

Since the metal has

Its density = m/v where

ρ = m/lwh

ρ = 4.56 g/(1.54 cm × 6.24 cm × 1.00 cm)

ρ = 4.56 g/9.6096 cm³

ρ = 0.475 g/cm³

ρ = 0.48 g/cm³

To find the absolute uncertainty in density, we first find the relative uncertainty which is given by

Δρ/ρ = √[(Δm/m)² + (Δl/l)² + (Δh/h)² + (Δw/w)²] where

Substituting the values of the variables into the equation, we have

Δρ/ρ = √[(Δm/m)² + (Δl/l)² + (Δh/h)² + (Δw/w)²]

Δρ/ρ = √[(0.05 g/4.56 g)² + (0.05 cm/1.54 cm)² + (0.05 cm/6.24 cm)² + (0.05 cm/1.00 cm)²]

Δρ/ρ = √[(0.010965)² + (0.032468)² + (0.008013)² + (0.05)²]

Δρ/ρ = √[0.00012023 + 0.00105417 + 0.00006421 + 0.0025]

Δρ/ρ = √0.00373861

Δρ/ρ = ± 0.061

Δρ/ρ ≅ ±0.06

So, the absolute uncertainty in density, Δρ = Δρ/ρ × ρ

= ±0.06 × 0.48 g/cm³

= ± 0.029 g/cm³

≅ ± 0.03 g/cm³

So, the density of the metal including absolute uncertainty is ρ = 0.48 g/cm³ ± 0.03 g/cm³

Answer:

Each carbon atom is covalently bonded to 4 other carbon atoms in diamond. A large amount of energy is required to split these atoms apart. This is because of the fact that covalent bonds are strong.

In diamond 4 carbon atoms are strongly bonded with covalent bond and they form giant covalent structure which requires large amount of energy to break down, that’s why diamond has a high melting point. It does not conduct electricity.

The metals in the following set which will have equal density are:

So, the correct options are 2,3 and 6.

A substance or object's density can be found out by comparing its mass to volume. Density is calculated using the formula:

[tex]density = \frac{mass}{volume}[/tex]

It is an essential property that the density of the same material remains constant at varied masses and volumes. Since the metal used in both situations is the same and metal has a fixed value of density, the choice with sets of the same metals has equal densities across the possibilities provided.

Explanation:

The influence of various wet chemical treatments on the germanium wafer surface has been examined. The GeO2 part of the native oxide is readily dissolved in water. The solubility of the GeO2 in aqueous solutions and the fast oxidation of germanium makes commonly used silicon treatments nonapplicable due to the relatively high etch rates. In various etching chemistries, the underlying suboxide is not attacked. A hydroxylated suboxide might be an ideal starting surface for ALD, because of its low contribution to electrical thickness. HBr removes even the suboxide and yields a completely oxide-free germanium surface which makes it a candidate surface preparation technique for epitaxial growth. The same result is obtained using a HI dip followed by a DIW rinse. Oxide is growing in CR-air, while in N 2 ambient the surface remains stable.

An oxide is a category of chemical compound that has one or more oxygen atoms as well as another element in its composition such as Li2O, CO2, H2O, etc.

An atom of mercury will have 6 - orbitals because it can be found on the 6-period in the periodic table of elements.

Orbitals or shells are energy levels in which electrons are placed within an atom.

Let us write the shell notation of the element:

    Hg has 80 electrons:

            K     L    M   N     O   P

            2      8   18    32    18  2

So, we have six orbitals

Answer:

Number of protons = 16

Number of neutrons = 16

Number of electrons = 18

Explanation:

The atom given is (32,16)S_2.

This simply Sulphur atom.

What (32,16)S_2 implies is that;

Atomic number = 16

Mass number = 32

Now atomic number means number of protons present in the atom

While mass number means number of sum of protons and neutrons present in the atom

Thus;

Number of protons = 16

Number of neutrons = 32 - 16 = 16

Now, for a neutral atom, number of protons is equal to number of electrons.

However, in this case it's not neutral but has a charge of -2.

Thus,

Number of electrons = 16 + 2 = 18 electrons

Explanation:

Because I used the elimination rule none of the other ones could be an answer.

When a total of 12g of carbon dioxide and water react in photosynthesis would produce 12 grams (g) of glucose and oxygen. Therefore, option (A) is correct.

Photosynthesis can be described as the process that takes place in plants through photosynthetic pigments such as chlorophyll. All green plants have a photosynthesis process to produce glucose by using water, carbon dioxide, and sunlight. The side product of this process in plants is oxygen.

The photosynthesis process is also utilized by algae to change solar energy into chemical energy. Photosynthesis takes place when plants utilize sunlight to change carbon dioxide and water into glucose and oxygen.

The Chemical equation of photosynthesis in plants is:

6CO₂  + 6 H₂O  →   C₆H₁₂O₆ +  6O₂

For a balanced chemical reaction, the total mass of the reactant is equal to the total mass of the products, so if the 12 g of carbon dioxide and water react with each other then 12 g of glucose and oxygen will be produced.
