Answer:

Mass = 6.706 g

Explanation:

Given data:

Mass of lithium hydroxide = ?

Volume of lithium hydroxide = 450 mL (450/1000 = 0.450 L)

Molarity of lithium hydroxide = 0.55 M

Solution:

Formula:

Molarity = number of moles / volume in L

0.55 M = number of moles / 0.450 L

Number of moles = 0.55 M × 0.450 L

Number of moles = 0.25 mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 0.25 mol × 23.95 g/mol

Mass = 6.706 g

Answer:

C) Boiling point because it is an intensive property.

The statement describes a property that will be the same for both students is (B). mass because it is an extensive property Hence Option (B) is correct.

A property known as an extensive property depends on the quantity of materials in a sample. A couple of instances of extensive attributes are mass and volume.

According to how a property varies as the system's size changes, physical qualities of materials and systems are sometimes classified as either intensive or extensive.

Therefore, The statement describes a property that will be the same for both students is (B). mass because it is an extensive property Hence Option (B) is correct.

Answer:

Ionic bonding is the type of bond that is made between a nonmetal and a metal. In this type of union, one of the elements yields electrons and the other accepts electrons.

In this case, the metal is Lithium, we need a nonmetal to complete the union. (Don't know if you need this or anything but here you go)

Beryllium is a metal.

Calcium is a metal.

Fluoride is a nonmetal.

Sodium is a metal.

After the analysis, we conclude that the correct answer is Fluoride since it is the only one that is a nonmetal.

Explanation:

The relative atomic mass, Ar, of the element Z is 32.1.

The relative atomic mass of the element Z is determined as follows:

compound formed between Z and Cl is ZCl₂

This implies that Z is an element in group 2A of the periodic table

percentage composition by mass of the elements in ZCl₂ are given as follows: Z = 31.13; Cl = 68.87

atomic mass of Cl = 35.5

mass of Cl in the compound = 35.5 * 2 = 71.0

68.87% of the compound has a mass = 71.0 g

mass of the compound (100%) ZCl₂ = 71.0 * 100/68.87

mass of the compound ZCl₂ = 103.1

Relative atomic mass, Ar, of Z = 103.1 - 71

Relative atomic mass, Ar, of Z = 32.1

Answer:

Magnesium and barium

Explanation:

They are both Alkaline earth metals. All the alkaline earth metals react with water to produce hydrogen gas and the metal hydroxide, although somewhat less vigorously than the alkali metals.

The organization and colors in the periodic table magnesium and barium are the two element with most of the similar properties because they both belongs to alkaline earth metals.

Periodic table are defined as an arrangement of all the elements known to man in accordance with their increasing atomic properties and recurring chemical properties. 118 elements are arranged in periodic table.

Alkaline earth metals are defined as any of the divalent strongly basic metal of group 2 of a periodic table comprising beryllium, magnesium, calcium, barium and radium.  

Thus, the organization and colors in the periodic table magnesium and barium are the two element with most of the similar properties because they both belongs to alkaline earth metals.

Answer:

P₂ =  50 mmHg

Explanation:

Given data:

Initial volume of gas = 80 mL

Initial pressure of gas = 100 mmHg

Final volume = 160 mL

Final pressure = ?

Temperature = constant

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

100 mmHg × 80 mL = P₂ × 160 mL

P₂ = 8000 mmHg. mL/ 160 mL

P₂ =  50 mmHg

The second choice and can i have brainiest

Explanation:

The substance is called dark matter because the term dark matter describes matter that cannot be seen because it does not give off light. It can only be detected by observing its gravitational effects on other types of matter (option D).

Dark matter in physics or astronomy are particles of matter that cannot be detected by their radiation but whose presence is inferred from gravitational effects.

According to this question, the presence of dark matter is one piece of evidence that supports the Big Bang theory.

However, this matter is called "dark" because it does not appear to interact with the electromagnetic field i.e. it does not absorb, reflect, or emit electromagnetic radiation and is, therefore, difficult to detect.

Therefore, the substance is called dark matter because the term dark matter describes matter that cannot be seen because it does not give off light. It can only be detected by observing its gravitational effects on other types of matter.
