Answers

Answer:

The alkali metals/group 1 are recognized as a group and family of elements. These elements are metals. Sodium and potassium are examples of elements in this family. Hydrogen is not considered an alkali metal because the gas does not exhibit the typical properties of the group. The largest family of elements consists of transition metals/group 3-12/group 3a. The center of the periodic table contains the transition metals, plus the two rows below the body of the table (lanthanides and actinides) are special transition metals. Even though both are metals, transition metals have higher melting points; they have higher density; they are less reactive with water; they react and form ions with different charges, but Group 1 metals only form 1+ ions.

(2 RIGHT CHOICES)
add a proton
add a neutron
add an electron

Answers

If you want to change the mass of your atom by 1 or more mass units, you can either? Add a proton and Add a neutron.

Explanation:

Option A and Option B is your answers.

To change the mass of your atom by more mass units ; you can add a proton or add a neutron ( A and B )

The nucleus of an atom is composed of a neutron and a proton while the outer shell of an atom comprises of the electrons.

The mass of an atom is dependent on the mass of the nucleus of the atom therefore to increase the mass of the atom by any number of mass units you can either add a proton or a neutron to the nucleus of the cell.

Hence we can conclude that to change the mass of your atom you can add a proton or add a neutron to the nucleus of the atom

Answers

Answer: your question is easy 21 L

By using ideal gas law the amount of volume will be 21 L.

What is ideal gas law?

The general gas equation, commonly known as the ideal gas law, is the state equation of a hypothetical ideal gas.

Calculation of volume by using ideal gas law.

Given data:

P = 5.1 atm

n = 3.7 moles

T = 75°C (273 + 75) = 348 K

V = ?

Put the given data in ideal gas law.

PV = nRT

V = nRT / P

V = 3.7 × 8.31 × 348 / 5.1

V = 2098

V = 21 L

Therefore, By using ideal gas law the amount of volume will be 21 L.

9. In a laboratory experiment, two groups of rats are fed two different fatty acids as their sole source of carbon for a month. The first group gets heptanoic acid (7:0), and the second gets octanoic acid (8:0). After the experiment, a striking difference is seen between the two groups. Those in the first group are healthy and have gained weight, whereas those in the second group are weak and have lost weight as a result of losing muscle mass. What is the biochemical basis for this difference

Answers

Answer:

Beta oxidation of the odd chain heptanoic acid will produce propionyl CoA, which can be converted in several steps to oxaloacetate. Oxaloacetate is the starting material for the process of gluconeogenesis (producing glucose from noncarbohydrate precursors). This gives extra glucose to the first group, so they will be healthier and gain weight. Beta oxidation of the even chain will entirely be oxidized to acetyl Co-A (one of the precursors of the TCA cycle). This will lead to a large excess of ketone bodies instead of glucose for energy, which will lead to the second group being weak and losing weight.

Explanation:

The difference is seen in having an odd chain and an even chain of fatty acids and how they are broken down and used in the body.

Calculate the pH for a 1.0 x 10-5 M solution of OH at 25°C.
pH = -log[H*), pOH = -log[OH-]
14 = pH + POH
0 pH = 11.00
0 pH = 9.00
0 pH = 6.00
0 pH = 3.00

Answers

Answer:

ph=9.00

Explanation:

Given 1.0x10^-15M of OH at 25c

first find Poh from Poh=-log[OH]

then Poh=-log[1.0x10^-5]

from above Ph=5

then find Ph from ph+poh =pw

where pw=14

ph+5=14

ph=9.00

The pH for a 1.0 x 10-5 M solution of OH at 25°C is 9.

What is pH?pH is a measure of acidity and basicity of aqueous solution. The range of pH goes from 0 - 14, with 7 being neutral. pH of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.pH is the measure of the relative amount of free hydrogen and hydroxyl ions in aqueous or other solutions.

In water pH + pOH=14

pH = 14 - pOH = 14 - 5 = 9

From definition, pOH = - log₁₀ [OH⁻]

Thus pOH = -log₁₀ (1 x 10⁻⁵)

= - (-5) = 5

pH + pOH = 14

pH = 14 - pOH

= 14 - 5 = 9

pH = 9

Hence, pH = 9 is the correct answer.

explain why copper 2 oxide is a base although it does not turn litmus paper to blue

Answers

Answer:

See explanation

Explanation:

Copper II oxide is a base but not an alkali. An alkali is a soluble base. Since Copper II oxide is not soluble in water then it is not an alkali.

Let us recall that the change of colour of litmus with an alkali requires the presence of water. In the absence of water, solid Copper II oxide does not turn red litmus paper blue.

The ability to turn red litmus paper blue is commonly observed with alkalis and Copper II oxide is not an alkali.

Also recall that since Copper II oxide is not soluble, hydroxide ions are absent hence Copper II oxide does not turn red litmus paper blue.

B. Metals, Non-Metals, Metalloids

Metals: located in the South and West of Periodic Table. Tend to give up electrons (form cations) and form simple ionic compounds with non-metal anions. Most of the 118 known elements are metals.

2. Non-Metals : located in the North and East of the Periodic Table. Tend to attract electrons (form anions) and combine with metal cations to make ionics, or share them with other non-metals and form covalent compounds . There are nineteen nonmetals, if we consider the ‘latest” two, which are not well characterized and have fleeting lifetimes.

3. Metalloids: straddle a staircase-like region between metals and non-metals. Their properties are intermediate between metals and non metals (in varying proportions). There are only seven metalloids.

How many grams is 2.393 x 10^24 atoms of O?
70.45 g O
140.9 g O
63.58 mole O
63.58 g O

Answers

Answer:

63.58 g O

Explanation:

To calculate the mass of O atoms, the number of moles of O atoms are needed and can be calculated as follows:

n (no. of moles) = nA ÷ 6.02 × 10^23

n = 2.393 x 10^24 ÷ 6.02 × 10^23

n = 0.398 × 10^ (24-23)

n = 0.398 × 10^1

n = 3.98moles.

To calculate the mass of Oxygen, we use the following formula:

moles = mass/molar mass

Molar mass of O = 16.

3.98 = m/16

m = 3.98 × 16

m = 63.68grams of Oxygen.

Answer:

Solution given:

[tex]1 mole \:of O=6.023×10^{23} atoms[/tex]

1 mole of O =16g

we have

[tex] 6.023×10^{23} atoms\: of O=16g[/tex]

now

[tex] 2.393 × 10^{24} atoms\: of \:O\\=16/6.023×10^{23}*2.393 x 10^{24}g\\=63.57g[/tex]

63.57g is a required mass of O.
