If phosphofructokinase experienced a mutation that interfered with substrate binding, then what other enzyme is going to be most immediately impacted in terms of accessing substrate?
A. aldolase
B. fumarase
C. glucolactonase
D. hexokinase

Answers

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.

How much energy is needed to heat 40.5g of water from 15.6°C to 73.0°C

Answers

Answer:

9717.246 J

Explanation:

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

Mass (m) of water = 40.5 g

Initial temperature (T₁) = 15.6 °C

Final temperature (T₂) = 73 °C

Specific heat capacity (C) of water = 4.18 J/gºC

Heat (Q) =.?

Next, we shall determine the change in the temperature of water. This can be obtained as follow:

Initial temperature (T₁) = 15.6 °C

Final temperature (T₂) = 73 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 73 – 15.6

ΔT = 57.4 °C

Finally, we shall determine the heat energy required. This can be obtained as follow:

Mass (m) of water = 40.5 g

Specific heat capacity (C) of water = 4.18 J/gºC

Change in temperature (ΔT) = 57.4 °C

Heat (Q) =.?

Q = MCΔT

Q = 40.5 × 4.18 × 57.4

Q = 9717.246 J

Thus, the heat energy required is 9717.246 J

ammonium phosphate is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid with liquid ammonia. Calculate the moles of ammonium phosphate produced by the reaction of 2.4 mol of ammonia. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

Answers

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.)"

What is the mass of .89 moles of lithium metal, used in laptop batteries?

Answers

6.17749 would be the mass

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.

Number of moles:

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.

How many moles of ethane gas, C2H6(g), will occupy 15.0 L at 30 degrees Celsius and 5.0 atm?

Answers

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

Answers

Answer:

answer of this question is option. 3. compound 1 is ionic ,and 2 is molecular

Compound 1 is ionic and compound 2 is molecular. The correct option is 3) Compound 1 is ionic, and compound 2 is molecular

From the question,

We are to classify the compounds according to the information provided in the table

First,

We will list the properties of ionic and molecular compounds

Properties of ionic compounds

The exist as solid at room temperature. They generally have high melting and boiling temperatures. They are good electrical conductors when molten or in solution.

Properties of molecular compounds

They can exist as solid, liquid or gas.They generally have low melting and boiling temperatures. They are poor electrical conductors.

In the given table,

Compound 1 has high melting and boiling points, and it is a good electrical conductor. Therefore, compound 1 is ionic

Compound 2 has low melting and boiling points, and it is a poor electrical conductor. Therefore, compound 2 is molecular

Hence, Compound 1 is ionic and compound 2 is molecular. The correct option is 3) Compound 1 is ionic, and compound 2 is molecular

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

Watch the animation and identify the correct conditions for forming a hydrogen bond.
A. A hydrogen bond is equivalent to a covalent bond.
B. A hydrogen bond is possible with only certain hydrogen-containing compounds.
C. Hydrogen bonding occurs when a hydrogen atom is covalently bonded to an N , O, or F atom.
D. The CH4 molecule exhibits hydrogen bonding.
E. A hydrogen atom acquires a partial positive charge when it is covalently bonded to an F atom.

Answers

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.
