Molarity: concentration measured by the number of moles of solute per liter of solution 3)

Explanation:

According to molar concentration, molarity of solution is 1.104 moles per liter and molar mass is 160.437 g/mole.

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.

Molarity  of solution is obtained as, 22.2/160.437×1/0.125=1.104 moles per liter.Molar mass of  LiClO₄.3 H₂O is 160.437 g/mole.

We have that for the Question "If the specific heat of Copper is 0.385 J/g °C and I add 10 kJ of heat to a 10kg block of copper, how much will the temperature of copper change?" it can be said that the temperature of copper change is

dt=2.60C

Option B

From the question we are told

If the specific heat of Copper is 0.385 J/g °C and I add 10 kJ of heat to a 10kg block of copper, how much will the temperature of copper change?

a. 0.384 °C

b. 2.60 °C

c. 38.4 °C

d. 384 °C

e. more than 400°C

Generally the equation for the Heat   is mathematically given as

Q=Mcdt

Therefore

dt=\frac{1}{0.385}

dt=2.60C

Therefore

the temperature of copper change is

dt=2.60C

Answer:

All amino acids are stereoisomers with the exception of glycine (because it has no chiral centers) and the two types are enantiomers and diastereomers

Explanation:

Not sure how in depth you need but the most fundamental categories are:

Enantiomers: non superimposable images which means that they cannot be placed on top of one another and look perfectly identical and instead are structurally the same but flipped in the opposite direction. An example being D-alanine and L-alanine.

Diastereomers: The molecules are superimposable which means they have an identical structure that will look the same placed on top of one another however, the compounds attached to the structure are placed in different orders an example being, L-isoleucine and D-allo-isoleucine (compounds in same place but isoleucine has two hydrogens positioned forward while allo-iso have one positioned forward and one positioned in the back)

The common type of isomerism among amino acids is the optical isomerism.

Isomerism refers to a situation in which there are two or more compounds that have the same molecular formula but different structural formulas. When two compounds have the same molecular formula but different atom to atom connectivity, they are called stereoisomers. Stereoisomers that are mirror images of each other are called enantiomers.

The common type of isomerism among amino acids is the optical isomerism. The optical isomers of alanine are shown in the image attached.

Taking into account the definition of density and scientific notation, the density of olive oil is 0.000911 [tex]\frac{kg}{mL}[/tex] or 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.  That is, density is the relationship between the weight (mass) of a substance and the volume it occupies.

The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

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

In this case, you know that:

Replacing in the definition of density:

[tex]density=\frac{0.216 kg}{237 mL}[/tex]

Solving:

density= 0.000911 [tex]\frac{kg}{mL}[/tex]

On the other side, scientific notation is a quick way to represent a number using powers of base 10.  

The numbers are written as a product:

a×10ⁿ

where:

In this case, the density expressed in scientific notation is: 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]

In summary, the density of olive oil is 0.000911 [tex]\frac{kg}{mL}[/tex] or 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]

Carbon-14

Explanation:

It's carbon, because the element has 6 proton.

It's not an ion, because there are same number of proton and electron 6=6

It is carbon-14 because 6 proton + 8 neutron = 14

Answer:

A type of an atom which has a different number of neutrons but the same atomic number, therefore making it the same element. This atom would still have the same properties as well. (Ex: Vanadium-51 is an isotope of Vanadium that has 51 neutrons but still has 23 protons, as its atomic number is 23.)

Isotopes are variants of an element that have the same number of protons in their atomic nucleus, identifying them as the same chemical element, but differ in the number of neutrons.

The variations in neutron numbers among isotopes lead to differences in their atomic masses, resulting in isotopes having slightly different physical properties while retaining similar chemical behavior.

For example, in the case of boron, the two isotopes listed may have the same number of protons (5), but one has 6 neutrons, and the other has 7 neutrons, leading to slightly different atomic masses.

Similarly, for carbon and oxygen, the isotopes exhibit variations in neutron numbers while maintaining the same number of protons, defining them as isotopes of the respective elements. Isotopes play a crucial role in various scientific fields, including radiometric dating, nuclear energy, and medical imaging.

Answer:Lower

Explanation:

( just had the question on ck12.)

Elements in the alkaline earth metal family of the periodic table have lower electronegativity values than elements in the halogen family of the periodic table as they have less electrons in their valence shell.

Periodic table is a tabular arrangement of elements in the form of a table. In the periodic table, elements are arranged according to the modern periodic law which states that the properties of elements are a periodic function of their atomic numbers.

It is called as periodic because properties repeat after regular intervals of atomic numbers . It is a tabular arrangement consisting of seven horizontal rows called periods and eighteen vertical columns called groups.

Elements present in the same group have same number of valence electrons and hence have similar properties while elements present in the same period show gradual variation in properties due to addition of one electron for each successive element in a period.
