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

so

ph+5=14

ph=9.00

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

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.

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.

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.

Answer:

There are 10,000 grams of octane in the tank of the sports car when it is full

Explanation:

To solve this problem, we simply need to convert the mass of octane- 93  from kilograms to grams, using the standard conversion factor which is given below.

it will take 10kg of octane-93 to  fill up the tank

1 kg = 1000grammes

therefore 10 kg = 10 X 1000 = 10,000 grams.

Hence, there are 10,000 grams of octane in the tank of the sports car when it is full.

Answer:

Saturated alkyne

Explanation:

The hydrocarbons are known as the compounds which is made up of only carbon and hydrogen atoms. They may be saturated or unsaturated based on the number of bonds present. The molecule H-C≡C-H is an Unsaturated alkyne. The correct option is B.

The hydrocarbons in which the carbon and hydrogen atoms are connected through double or triple bonds are known as unsaturated hydrocarbons. Here ethyne is an unsaturated hydrocarbon.

Ethyne is an alkyne which have the C-C  and C-H atoms connected through triple and single bonds.

Thus ethyne is option B.

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

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.

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.
