Answer:

B

Explanation:

Answer:

eight

Because the noble gases are the least reactive of all elements, their eight valence electrons are used as the standard for nonreactivity and to explain how other elements interact.

Answer:

Wavelengths..

Explanation:

The colors we see always go from red, which is least refracted, through orange, yellow, green, blue, indigo and violet -- Roy G Biv. The blue, indigo and violet wavelengths are refracted the most as sunlight passes through raindrops.

Answer:

In physics and chemistry, ionization energy or ionisation energy, is the minimum amount of energy required to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule.

Explanation:

Answer:

Yes. It is definitely correct

Explanation:

The increase in mass is because the iron fillings have combined with a sulfide to produce iron sulfide and so the mass will increase.

In such a reaction like this, the mass of the reactants must be conserved. By so doing, the mass of reactants and products must be the same.

When two substances combine together, their masses added up to that of the individual masses. This helps to conserve the mass.

Explanation:

2.1 x 10⁵⁶ atoms

The mole is the number of particles(molecules,atoms,ions) contained in a substance

1 mol = 6.02.10²³

number of atoms :

[tex]\tt 3.49\times 10^{32}\times 6.02\times 10^{23}=2.1\times 10^{56}[/tex]

The balanced equation for the reaction is

3CuCl₂(aq) + 2Al(s) = 2AlCl₃(aq) + 3Cu(s). The correct option is - D) 3CuCl2(aq) + 2Al(s) = 2AlCl3(aq) + 3Cu(s)

From the question,

We are to determine which of the given equation for the described reaction is balanced.

The described reaction is the reaction between aqueous copper (II) chloride and solid aluminum to produce aqueous aluminum chloride and solid copper.

That is,

CuCl₂(aq) + Al(s) = AlCl₃(aq) + Cu(s)

Now, we will balance the above equation, using the smallest whole number coefficients

The balanced equation for the reaction is

3CuCl₂(aq) + 2Al(s) = 2AlCl₃(aq) + 3Cu(s)

Hence, the balanced equation for the reaction is

3CuCl₂(aq) + 2Al(s) = 2AlCl₃(aq) + 3Cu(s). The correct option is - D) 3CuCl2(aq) + 2Al(s) = 2AlCl3(aq) + 3Cu(s)

Explanation:

A gene mutation can be defined as a permanent change in the DNA sequence that composes a gene, resulting in the observation that the sequence differs from what is obtainable in most individuals that make up the  population. Mutations range from a change in a single DNA building block (change in the sequence of base pairs) to changes in a large segment of a chromosome that includes multiple genes.

Mutation in the color of the wings of the housefly can be passed on to the next generation. If this trait enhances survival of the butterflies, the orange winged butterflies will eventual become extinct and become entirely replaced by the white winged butterflies. This implies that gene pool has been completely modified.

If same kind of mutation of pigmentation of wings is observed in the butterfly then they will result in a white butterfly.

If a gene of the DNA get damaged or changes in such a way that it also results in the changing of genetic message carried by that gene and this process is known by the name of mutation.

In the given question by breeding orange butterfly with a white butterfly in the latest generation of animals, notices a mutation in the genes that calls for pigment in the wings. If the mutation of pigmentation of wings is passed to the next generations with the  same changes in the gene of DNA, then after some generation we would get white butterfly.

Hence, if the same changes observed in the mutation of pigmentation of wings then we get a white butterfly.

Answer:

i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.

An acid is a substance that produces (H+) as the only positive ion when mixed with water. A base is a substance that produces (OH–) as the only negative ion when mixed with water.

Answer:

An acid increases the concentration, A base is a substance that releases hydroxide

Explanation: A base donates electrons and accepts protons, and acid is a substance that donates protons.

Answer:

Explanation:

Since electrons are particles that are in constant movement in a wave-like motion, is impossible to know exactly their position and velocity at all times. That's why instead of defining an orbit for them we define an atomic orbital, which is a location in space where the probability of finding an electron is high (therefore, is an electron dense zone). Since this zone has not defined limits (the wave function characterizing the orbital extend from the nucleus to infinity), the further we go from the nucleus the less dense this "cloud" is.

There is about a 90 percent probability of finding the electron  within a sphere of radius 100 pm surrounding the nucleus.  Thus, we can represent the 1 s orbital by drawing a boundary surface diagram that  encloses about 90 percent of the total electron density in an orbital, and the shape of this orbital is a sphere.

The boundary surface diagrams of p orbitals, for example, will have the shape of two lobes on opposite sides of the nucleus, that means that within this two lobes we have a 90 percent probability of finding the electron, and so on.

Answer:

Covalent Bonds

General Formulas and Concepts:

Explanation:

We have 3 types of bonds: Polar Covalent, Nonpolar Covalent, and Ionic bonds.

Nonpolar Covalent bonds share the electrons equally between the compound.

Polar Covalent bonds do NOT share the electrons equally, but STILL SHARE the electrons; the electron tends to stay with the element with the stronger electron affinity and thus creates dipoles.

Ionic bonds DO NOT share electrons. The electrons are transferred to the respective elements.
