how did domestication of early crops start?​

Answers

Answer:

In the Fertile Crescent in the Middle East, cereal crops were first domesticated about 11,000 years ago. Generally, the first domesticated crops were annuals with big seeds or fruits. ... Humans began to transition from a hunter-gatherer culture to a settled farming society as domestication took place.

What is the temperature, in degrees Celsius, of a 10.5 grams sample of Neon gas confined to a volume of 2.50 L at a pressure of 1.00 atm.

Answers

Answer:

–215 °C

Explanation:

From the question given above, the following data were obtained:

Mass of Ne = 10.5 g

Volume (V) = 2.50 L

Pressure (P) = 1 atm

Temperature (T) =?

Next, we shall determine the number of mole present in 10.5 gof Neon, Ne. This can be obtained as follow:

Mass of Ne = 10.5 g

Molar mass of Ne = 20 g/mol

Mole of Ne =.?

Mole = mass /Molar mass

Mole of Ne = 10.5 / 20

Mole of Ne = 0.525 mole

Next, we shall determine the temperature of the sample of Neon, Ne. This can be obtained as follow:

Volume (V) = 2.50 L

Pressure (P) = 1 atm

Number of mole (n) = 0.525 mole

Gas constant (R) = 0.0821 atm.L/Kmol

Temperature (T) =?

PV = nRT

1 × 2.5 = 0.525 × 0.0821 × T

2.5 = 0.525 × 0.0821 × T

Divide both side by 0.525 × 0.0821

T = 2.5 / (0.525 × 0.0821)

T = 58 K

Finally, we shall convert 58 K to degree celsius (°C). This can be obtained as follow:

T(°C) = T(K) – 273

T(K) = 58 K

T(°C) = 58 – 273

T(°C) = –215 °C

Thus, the temperature of the sample of Neon gas is –215 °C.

What are valence electrons? How do you quickly determine the number of valence electrons an
atom has?

Answers

Answer:

Electrons that arent electrons

Explanation:

I teach chem

Answer:

Valence electrons are the electrons found in the highest and main energy level of the atom, being these responsible for the interaction between atoms of different species or between atoms of the same species. You can quickly determine these by looking at a periodic table like this one... Which is where the roman numbers come in and show the valence electrons.

How many grams of glycine amide should be added to 1.00 g of glycine amide hydrochloride to give 100 mL of solution with pH 8.00

Answers

Answer:

0.4235 g of glycine amide should be added

Explanation:

From the given information:

The equation of the reaction can be illustrated as:

[tex]BH^+ \to B^+ + H ^-[/tex]

where:

mass of glycine amide hydrochloride = 1.00 g

Suppose x be the amount of (in grams) of glycine amide that is required to be added; Then:

[tex][BH^+] = \dfrac{1.00 \ g}{110.54 \ gmol \times 0.100 L}[/tex]

[tex][BH^+]=[/tex] 0.0905 M

So, For [B} i.e, for glycine amide

[tex][B] = \dfrac{x \ g}{74.083 \ gmol \times 0.100 L}[/tex]

[B] = 0.135x  M

[tex]\dfrac{[B]}{[BH^+]}=\dfrac{0.135x \ M}{0.0905 \ M }}[/tex]

[tex]\dfrac{[B]}{[BH^+]}=1.49x[/tex]

The log of the above question can be computed as:

[tex]log _{10}\dfrac{[B]}{[BH^+]}=log _{10}1.49x[/tex]

[tex]pH = pK_a + log _{10} \dfrac{[B]}{[BH^+]}[/tex]

8.00 = 8.20 + [tex]log _{10}(1.49x)[/tex]

8.00 - 8.20 = [tex]log _{10}(1.49x)[/tex]

-0.20 = [tex]log _{10}(1.49x)[/tex]

1.49 x = [tex]10^{-0.20}[/tex]

1.49 x = 0.631

x = 0.631/1.49

x =  0.4235 g

In a certain chemical reaction, the bond energy of the products is 67 kJ and
that of the reactants is 52 kJ. Because energy is conserved, how much
potential energy does the system release or absorb?
O A. The reaction uses up 15 kJ of energy from the reaction system.
B. The reaction creates 15 kJ of energy when bonds form.
C. The reaction system absorbs 15 kJ of energy from the
surroundings.
O D. The surroundings absorb 15 kJ of potential energy.

Answers

D. The surroundings absorb 15 kJ of potential energy.

Further explanation

Chemical bonds = potential energy

ΔH reaction from bond energy is a breaking and forming reaction of the 2 reacting molecules

Can be formulated:

ΔH rxn =  ∑ the energy of the reagent bonds broken - ∑ the energy of the bonds formed by the product

The bond energy of the products is 67 kJ and reactants 52 kJ

[tex]\tt \Delta H_{rxn}=52-67=-15~kJ[/tex]

ΔH = negative ⇒The reaction is exothermic(releases heat to surrounding)

Answer:

C is right

Explanation:

Consider the following statements about first ionization energies:

I. Because the effective nuclear charge for Mg is greater than that for Be, the first ionization energy of Mg is greater than that of Be.
II. The first ionization energy of O is less than that of N because in O we must pair electrons in the 2p orbitals.
III. The first ionization energy of Ar is less than that of Ne because a 3p electron in Ar is farther from the nucleus than a 2p electron in Ne.

Which of the statements I, II, and III is or are true?

Answers

Answer:

I,II, III

Explanation:

Firstly, the magnitude of nuclear charge affects the first ionization energy of an element. Hence,as effective nuclear charge increases, the attraction between the nucleus and the outermost electron increases and ionization energy consequently increases. Thus Mg has a higher first ionization energy than Be.

Secondly, oxygen has an electron configuration of 1s2 2s2 2p4 while nitrogen has an electron configuration of 1s2 2s2 2p3. Now, recall that extra energy is often associated with half filled orbitals hence nitrogen has a higher first ionization energy than oxygen. Furthermore, the addition of electron to an already half filled 2p orbital in oxygen (pairing) leads to inter electronic repulsion and drastic fall in first ionization energy. Therefore, as we move from nitrogen to oxygen in the periodic table, greater inter-electron repulsion between two electrons in the same p-orbital counter balances the increase in effective nuclear charge hence nitrogen has a greater first ionization energy than oxygen.

Lastly, the 3p orbital is far away from the nucleus hence we expect it to feel less of nuclear attraction than a 2p orbital. Hence the first ionization energy of Ar is less than that of Ne.

how are compounds with metallic bonds similar to ionic compounds?

Answers

Answer:

Metals do not form double and triple bonds in general because metals want to lose electrons, not share, in order to become stable, and both compounds have high melting ppints

Compounds with metallic bonds and ionic compounds are similar in their melting point and boiling point, conductivity, solubility in polar solvents etc.

Ionic compounds are chemical compounds that are formed by the electrostatic attraction between oppositely charged ions.

Compounds with metallic bonds and ionic compounds are similar in several ways. Some of the similarities are:

1. High melting and boiling points: Both metallic and ionic compounds have high melting and boiling points due to the strong forces that hold the atoms or ions together.

2. Conductivity: Both metallic and ionic compounds are good conductors of electricity due to the presence of charged particles that can move freely.

3. Brittle: Ionic and metallic compounds are generally brittle in nature, meaning that they are prone to breaking or shattering when subjected to stress.

4. Solubility in polar solvents: Both metallic and ionic compounds are generally soluble in polar solvents such as water, due to the polar nature of the molecules.

In conclusion, compounds with metallic bonds and ionic compounds share several similarities. Both have high melting and boiling points, are good conductors of electricity, are brittle, and are generally soluble in polar solvents.

True or false: An oxidation number is not the same as an actual charge on an ion. True false question. True False

Answers

Answer:

True

Explanation:

They are actually the same

The answer is False.

The oxidation number is the number of electrons removed or added to an element or compound. This is also equal to the charge on the ion.

For example, if Sodium atom loses one electron, it becomes oxidized to the + 1 state.

Na → Na⁺ + e⁻.

So, the oxidation number of Sodium is the charge on the Sodium ion which is + 1.

So, the oxidation number is equal to the charge on the ion.

So, the answer is False.
