A person with a mass of 105 kg moves at a velocity of 1.5 m/s what is this person momentum?

Answer:

A. genetically identical

Explanation:

Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly

All the offspring that are produced in the process are genetically identical.

When we talk about this mode of reproduction, we talk about a mode of reproduction in which an organism reproduces without the fusion of gametes. This occurs essentially by cell division.

When this occur, there is no crossing of genetic material as such, all the offspring that are produced in the process are genetically identical.

Mass of barium nitrate needed = 25.74 g

Explanation:

Given data:

Molarity of solution = 0.197 M

Volume of solution = 500 mL (500 mL× 1 L /1000 mL = 0.5 L)

Mass of barium nitrate needed = ?

Solution:

Molarity = number of moles of solute / volume in L

0.197 M = number of moles of solute / 0.5 L

Number of moles of solute = 0.197 mol/L ×0.5 L

Number of moles of solute = 0.0985 mol

Mass of barium nitrate:

Mass = number of moles × molar mass

Mass = 0.0985 mol × 261.32 g/mol

Mass = 25.74 g

Answer:

excess reactant

Explanation:

The excess reactant is the reactant in a chemical reaction with a greater amount than necessary to react completely with the limiting reactant. It is the reactant(s) that remain after a chemical reaction has reached equilibrium.

In a reaction containing two reactants, if one of the reactants is in excess, the other reactant is known as the limiting reactant which decides the yield of the reaction.

In a reaction, all the reactants have to be in correct stoichiometry to complete the reaction. To achieve the mole ratio of the reactants is very much important for the completion of a reaction.

If a reactant is insufficient in amount, then the reaction will stop as soon as this reactant is consumed. Hence, this reactant determine the yield of the product. This reactant which is not in correct stoichiometry for the complete reaction is called the limiting reactant.

The reactant which is excess in quantity thus does not have a role in the yield of the reaction is called the excess reactant. Whatever, the concentration of this reactant in extra, the reaction does not proceed after the consumption of limiting reactant.

Answer:

[tex]{\rm Zn^{2+}}\, (aq) + {\rm 2\; OH^{-}}\, (aq) \to {\rm Zn(OH)_2}\, (s)[/tex].

Explanation:

Rewrite only the species that exist as ions. Those species typically include:

In this reaction, both [tex]{\rm ZnBr_2}\, (aq)[/tex] and [tex]{\rm NaBr}\, (aq)[/tex] are salts. The state symbol "[tex](aq)[/tex]" suggests that both of these salts are soluble. Hence, both of these salts exist as ions and should be rewritten:

Similarly, the state symbol "[tex](aq)[/tex]" suggests that the base [tex]\rm NaOH[/tex] is also soluble:

On the other hand, the state symbol "[tex](s)[/tex]" suggests that the base [tex]{\rm Zn(OH)_2}\, (s)[/tex] is a precipitate and is not soluble. Rather, the bonds within [tex]{\rm Zn(OH)_2}[/tex] stay mostly intact, and this species would not exist as ions. Hence, do not rewrite [tex]{\rm Zn(OH)_2}\, (s)\![/tex] when deriving the ionic equation for this reaction.

Hence, the ionic equation for this reaction would be:

[tex]\begin{aligned}&\underbrace{{\rm Zn^{2+}}\, (aq) + 2\, {\rm Br^{-}}\, (aq)}_{\text{from ${\rm ZnBr_2}\, (aq)$}} + \underbrace{2\, {\rm Na^{+}}\, (aq) + 2\, {\rm OH^{-}}\, (aq)}_{\text{from $2\, {\rm NaOH}\, (aq)$}} \\ & \to \underbrace{{\rm Zn(OH)_2}\, (s)}_{\text{precipitate}} + \underbrace{2\, {\rm Na^{+}}\, (aq) + 2\, {\rm Br^{-}}\, (aq)}_{\text{from $2\, {\rm NaBr}\, (aq)$}}\end{aligned}[/tex].

Eliminate species that are present on both sides of the ionic equation to obtain the net ionic equation. A species should be eliminated if only if an equal number of this species are found on both sides of the ionic equation. Otherwise, subtract from the side with a larger number of that species.

For this reaction, the net ionic equation would be:

[tex]{\rm Zn^{2+}}\, (aq) + {\rm 2\; OH^{-}}\, (aq) \to {\rm Zn(OH)_2}\, (s)[/tex].

Explanation:

Answer:

Rate constant = 0.01238 days⁻¹

Explanation:

The first order reaction has as general equation:

Ln[A] = -kt + Ln[A]₀

Where [A] is concentration of the reactant after time t,

k is rate constant

And [A]₀ the initial concentration of the reactant

The half-life is the time required to reach the half of the initial concentration. If [A]₀ = 1; [A] = 1/2

Replacing:

Ln[1/2] = -kt + Ln[1]

-0.693 = -k*56days

0.01238days⁻¹ = k

Mass of HF = ?

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of HF = 20.01 g/mol

by putting values,

Mass = 1.75 mol × 20.01 g/mol

Mass = 35.02 g

Since a single replacement reaction involves the change of an atom by another, the reaction is a single replacement reaction.

The term chemical reaction is another word for chemical change. It involves an interaction between two or more chemical species leading to the formation of a new chemical species.

The reaction AB + C → CB + A is a single replacement reaction because The A in the reactant side is replaced by C while it becomes displaced.

Answer:

A) gain an electron and increase in size

Explanation:

Fluorine is a Group 17 element, making it a halogen. This means that it has 7 valence electrons in its outer shell. It only needs one more electron to fill its outer shell and gain stability. When fluorine becomes an ion, it gains an electron and becomes F⁻. Adding electrons creates a larger ion because the electrons occupy a larger volume due to mutual repulsions pushing them apart.

Hope that helps.

When a fluorine atom becomes an anion, it will gain an electron and increase in size. Therefore, option (A) is correct.

An ion is a chemical specie that holds a positive or negative charge. The term ‘ion’ refers to atoms or molecules with non-zero net charges associated with them. Therefore, all ions have either a greater number of electrons than protons in their atomic structures or a greater number of protons than electrons.

If the number of protons is greater than electrons are termed to hold a net positive charge and are commonly referred to as cations. The ions that contain a greater number of electrons than protons hold a net negative charge and are known as anions.

The electronic configuration of the fluorine is 1s²2s²2p⁵. As the fluorine atom accepts one electron in its valence shell it becomes anion F⁻. The number of protons is less than electrons therefore effective nuclear charge decreases and the size of the ion increases.

PLEASE MARK AS BRAINLIEST

The reaction of Potassium sulfide with nitric acid is a double displacement reaction.

A displacement reaction can be defined as one wherein a set of atoms is displaced by another atom in a molecule. For example, when the iron metal is added to a solution of copper sulfate, it displaces the copper metal.

[tex]A + BC \longrightarrow AC + B[/tex]

A single displacement reaction can be described as a kind of oxidation-reduction reaction when an element moves out of a compound, one element is replaced by the other in a compound.

Double displacement reactions occur mostly in aqueous solutions wherein the ions precipitate and the exchange of ions takes place. The double displacement reaction can be represented as:

[tex]AB+CD\longrightarrow AC+ BD[/tex]

The reaction between the potassium sulfide and nitric acid gives hydrogen sulfide and potassium nitrate.

Answer:

Explanation:

Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. ... If sodium can transfer it's "spare" electron to chlorine (as shown above), both atoms will satisfy their full outer shell requirements, and an ionic bond will be formed. They combine as atoms, and separate as ions. When sodium and chlorine atoms come together to form sodium chloride (NaCl), they transfer an electron. ... Because the sodium ion has a positive charge, and the chlorine ion has a negative charge, they are attracted to each other, and form an ionic bond.

When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. ... The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
