Answer: A. aldolase

Explanation:

Phosphofructokinase, is an enzyme which is vital in the regulation of fermentation. It is involved in the glycolysis process.

When it experiences a mutation that was being interfered with the substrate binding, we should note that the enzyme that is going to be most immediately impacted in terms of accessing substrate is aldolase.

Answer:

B. It becomes plutonium-239.

Explanation:

When uranium  - 238 absorbs a neutron, it creates and becomes plutonium - 239 atom.

 This is a nuclear fission process in which a radioactive nucleus is bombarded with a neutron:

  ²³⁸₉₂U    +     ¹₀n   →      ²³⁹₉₂Pu

The plutonium produced is not stable and it immediately disintegrates further.

Answer:

0.0064 qt

Explanation:

Given data:

Density of mercury = 13.6 g/cm³

Mass of mercury = 83.0 g

How many quarts mercury have = ?

Solution:

First of all we will calculate the volume in cm³.

d = m/v

13.6 g/cm³ = 83.0 g / volume

Volume = 83.0 g /  13.6 g/cm³

Volume = 6.1 cm³

cm³ to L:

6.1 cm³ × 1 L / 1000  cm³

0.0061 L

In quarts:

1 L = 1.06 qt

0.0061 L × 1.06 qt / 1 L

0.0064 qt

The empirical formula is the simplest formula of a compound. To find the empirical formula, we follow the procedure below:

Elements                         Potassium                 Chromium         Oxygen

Mass                                  6.52                             4.34                  5.34

Molar mass                          39                               60                      16

Number of moles             6.52/39                     4.34/60             5.34/16

                                             0.167                          0.072              0.333

Divide through by

Empirical formula K₂CrO₅

The mass of lithium metal that is used in lithium batteries is 6.17 grams,  this can be calculated by using number of moles formula.

It is defined as the ratio between mass and molar mass.

It is given by:

Number of moles = mass / Molar mass

What information do we have?

Number of moles= 0.89 moles

Molar mass of Lithium metal= 6.941 g/mol

To find:

Mass of Lithium metal=?

On substituting the values

n= m/M

0.89 = m/ 6.941

m= 0.89*6.941

m= 6.177 grams

Thus, the mass of lithium metal is 6.177 grams.

Answer:

3

Explanation:

The reaction expression is given as:

      Al(OH)₃  +   HNO₃   →    H₂O   +  Al(NO₃)₃  

To solve this problem, let us assign coefficient a,b,c and d to each specie;

           aAl(OH)₃  +   bHNO₃   →    cH₂O   +  dAl(NO₃)₃  

Conserving Al : a  = d

                   O:  3a + 3b  = c + 9d

                   H: 3a + b  = 2c

                   N: b  = 3d

let a = 1 , d  = 1, b  = 3 , c = 3

  Multiply through by 3;

 a  = 1, b  = 3, c = 3 and d  = 1

   Al(OH)₃  +   3HNO₃   →    3H₂O   +  Al(NO₃)₃  

Answer:

1–ethoxybutane

Explanation:

In naming the above compound, the following must be observed:

1. The longest chain gives the root name of the compound.

2. The shorter chain is named as substituent together with the oxygen group as alkoxy.

3. Locate the position of the alkoxy group by giving it the lowest low count.

4. Combine the above to obtain the name of the compound.

Now we shall name the compound as follow:

1. The longest chain is carbon 4 i.e butane.

2. The shortest chain is ethyl (i.e –CH₂CH₃). This is named together with the oxygen atom as ethoxy.

3. The ethoxy group is located at carbon 1 of the butane chain since it is the functional group of the chain.

4. The name of the compound is:

1–ethoxybutane.

Answer:

3 mol

Explanation:

Given data:

Volume of ethane = 15.0 L

Temperature = 30°C

Pressure = 5.0 atm

Number of moles of ethane = ?

Solution:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

30+273 = 303 K

5.0 atm × 15.0 L = n×0.0821 atm.L/ mol.K   × 303 K

75 atm.L =  n× 24.87 atm.L/ mol

n = 75 atm.L / 24.87 atm.L/ mol

n = 3 mol

Answer:

0.57 moles (NH4)3PO4 (2 sig. figs.)

Explanation:

To quote, J.R.

"Note:  liquid ammonia (NH3) is actually aqueous ammonium hydroxide (NH4OH) because NH3 + H2O -> NH4OH.

H3PO4(aq) + 3NH4OH(aq) ==> (NH4)3PO4 + 3H2O  

Assuming that H3PO4 is not limiting, i.e. it is present in excess

1.7 mol NH4OH x 1 mole (NH4)3PO4/3 moles NH4OH = 0.567 moles = 0.57 moles (NH4)3PO4 (2 sig. figs.)"

Answer:

options B,C and E are correct conditions for forming hydrogen bonds.

Explanation:

In order for particles to stick together or shows certain characteristics, there must be a bond of attractions that is making them to be able to stay together. Some of these attractions are strong while some are weak. The kind of attraction that is being considered in this question  is the hydrogen  bonding which is considered as part of the weak forces of attractions.

In order for hydrogen bonds to occur, there must be hydrogen atoms [option B is correct] and a much more electronegative elements such as oxygen, Fluorine and Nitrogen. Hence, option C is correct.

Since the Fluorine or oxygen or nitrogen have much more electronegative properties than hydrogen, it causes a partial negative charge on  Fluorine or oxygen or nitrogen and a partial positive charge on the Hydrogen. Thus, option E is correct.
