Explanation:

Glucose is the most common form of sugar in the blood and the body's primary source of energy. Glucose is derived from the meals we eat or produced by the body from other chemicals. The circulation transports glucose to the cells. Several hormones, including insulin, regulate blood glucose levels.

a simple sugar that is a component of many carbohydrates and is a vital source of energy in living things.

Blood sugar, often known as glucose, is the most common sugar present in the body. It is your body's major source of energy and comes from the food you eat. Glucose is carried by your blood to all of your body's cells, where it is used for energy.

That means that one mole of cobalt weighs 58.9332 grams (58.9332 g/mol). Based on that information, to convert 2 moles of cobalt to grams, we multiply 2 moles of cobalt by 58.9332.

12.04428152 x [tex]10^{23}[/tex] cobalt atoms are in 2 moles of cobalt.

A mole is defined as 6.02214076 ×[tex]10^{23}[/tex]

of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

One mole of cobalt is equal to 6.02214076 ×[tex]10^{23}[/tex] atoms.

2 moles of cobalt is equal to 6.02214076 × [tex]10^{23}[/tex]atoms x 2

12.04428152 x [tex]10^{23}[/tex]

Hence, 12.04428152 x [tex]10^{23}[/tex]cobalt atoms are in 2 moles of cobalt.

Considerando la definición de molaridad, la molaridad de una solución acuosa de ácido sulfúrico (H₂SO₄) es 0.5 [tex]\frac{moles}{litro}[/tex].

La molaridad es una medida de la concentración de un soluto en una disolución que se define como el número de moles de soluto que están disueltos en un determinado volumen.

La molaridad de una solución se calcula dividiendo los moles del soluto por el volumen de la solución:

[tex]Molaridad=\frac{numero de moles de soluto}{volumen}[/tex]

La Molaridad se expresa en las unidades [tex]\frac{moles}{litro}[/tex].

En este caso, sabes que una solución acuosa se preparó al mezclar 4 moles del ácido con suficiente agua hasta completar 8 litros de solución. Entonces, sabes que:

Reemplazando en la definición de molaridad:

[tex]Molaridad=\frac{4 moles}{8 litros}[/tex]

Resolviendo:

Molaridad= 0.5 [tex]\frac{moles}{litro}[/tex]

Finalmente, la molaridad de una solución acuosa de ácido sulfúrico (H₂SO₄) es 0.5 [tex]\frac{moles}{litro}[/tex].

The number of silicon atoms in atypical computer chips(0.001g of silicon) is 2.14 × 10¹⁹ atoms

The atomic mass of silicon = 28.0855 amu

Using the mole concept that 1 mole = 6.022  × 10²³.

This number is called the Avogadro's number.

Therefore,

1 mole /  28.0855g  of silicon contains 6.022  × 10²³ atoms of silicon

0.001 g will contain ? atoms of silicon

cross multiply

number of atoms of silicon = 6.022  × 10²³ × 0.001 / 28.0855

number of atoms of silicon = 6.022 × 10²⁰ / 28.0855

number of atoms of silicon = 2.14 × 10¹⁹ atoms

Copper

Explanation:

Copper has this electronic configuration.

You can count the total number of electrons

= 29

Cu is the 29 th in the periodic table.( atomic number = 29)

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the given electronic configuration represents copper element.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

The systematic distribution of electrons in the various atomic orbitals is called its electronic configuration. The atomic number of copper is 29. The electronic configuration of copper is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d¹⁰. 1,2,3 represents the number of shells and s and represents the orbitals. The superscripts represents the number of electrons in each orbitals.

Answer:

In order to solve for this you would need to plug it into an equation. You would add them all up to eachother after multiplying them by their percentages.

So it would be (0.75*48.90)+(0.18*49.10)+(0.07*50.20). Plug it all into a calculator and you get 49.027amu. Then you would round to significant figures so 49.03amu should be your answer.

Answer: remove a H2 molecule from the left side of the equation

Explanation:

In the chemical equation and concept of balancing of equations if to ensure that no diatomic hydrogen  is left over remove a H₂ molecule from the left side of the equation.

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)

Explanation:

Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.

PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T

Density = 0.900 grams/L

R = 0.08206 L·atm/mole·K

T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)

Answer:

D. Na has a larger radius than Na+ because Na+ has lost its outermost energy shell.

Explanation:

The radius is larger because the diameter of Na+ is larger.

Sodium has smaller atomic  radius than sodium cation because sodium has expanded electron cloud.

Atomic radius is defined as the  distance between outermost shell and the nucleus. Atomic radius varies across the periodic table where in groups it increases due to the fact that new shells are added on moving sown the group.

While in a period it decreases from left to right across the periodic table as electrons are added to the same shell which causes contraction of the atom.In case of comparison between an atom and a cation an atom has smaller atomic radius due to presence of electrons while in case of ions atomic radius is smaller as they have less number of electrons.

Atoms have expanded electron cloud while the electron cloud in case ions is small , the reason being the presence of large number of electrons in case of atoms and less number of electrons in case of ions.

Answer:

Molarity NaOH = 0.85M (2 sig figs)

Explanation:

48.0ml(0.220M H₂SO₄) + 25ml(Xmolar NaOH)H₂SO₄ + 2NaOH => Na₂SO₄ + 2H₂O

2(molarity x volume) H₂SO₄ = (molarity x volume) NaOH

2(0.220M x 48.0ml) = 25.0ml x Molarity NaOH

Molarity NaOH = 2(0.220M x 48.0ml)/25.0ml = 0.8448M ≅ 0.85M (2 sig figs)

an highly valuable element with super and electric and thermal conductivity, high luster, and sensitivity.

Explanation:

A precious metal is a highly valuable element with super and electric and thermal conductivity, high luster, and sensitivity, hence option C is correct.

Rare metallic chemical elements with a high economic value are known as precious metals. The valuable metals are often less reactive chemically than most elements.

Iron-free metals and alloys are not considered base metals. Base metals have a propensity to tarnish, oxidize, or corrode with time or when exposed to the environment, in contrast to valuable metals.

Base metals typically cost less than precious metals since they are more plentiful in nature and sometimes easier to mine.

Therefore, a precious metal is a highly valuable element with super and electric and thermal conductivity, high luster, and sensitivity.
