Briefly explain the importance of ATP and its role in a cell.

Answers

Answer:

n energy-carrying molecule found in all living things' cells. ATP absorbs chemical energy from the breakdown of food molecules and uses it to power other cellular processes.

Explanation:

Hope it helps

ATP is a crucial energy molecule in cells, providing energy for various cellular processes.

ATP, or adenosine triphosphate, is often referred to as the "energy currency" of the cell. It plays a vital role in cellular metabolism by providing energy for various processes. ATP is composed of adenosine and three phosphate groups. The energy stored in ATP is released when the terminal phosphate group is hydrolyzed, forming ADP (adenosine diphosphate) and inorganic phosphate (Pi).

The role of ATP in a cell is multifaceted. Firstly, ATP powers cellular work by providing the energy needed for chemical reactions, such as biosynthesis, active transport, and muscle contraction. It acts as an immediate source of energy that can be rapidly used by the cell.

Secondly, ATP participates in signal transduction and cellular communication. It can be hydrolyzed to ADP and Pi, releasing energy that can activate signaling molecules and enzymes involved in cell signaling pathways.

Furthermore, ATP is involved in maintaining cell homeostasis. It provides energy for processes like ion pumps that maintain the electrochemical gradients across the cell membrane, allowing cells to regulate their internal environment.

Overall, ATP is crucial for the functioning of cells as it serves as an energy carrier, facilitating energy transfer and powering various cellular processes essential for growth, metabolism, and cell survival.

When 50 cm³ of hydrocarbon Y is burnt, it reacts with exactly 300 cm³ of oxygen to form 200 cm³ of carbon dioxide. Water is also formed in the reaction. Deduce the equation for this reaction. Explain your reasoning.

Answers

Answer:

C2H4 + 3O2---> 2CO2 + 2H2O

Explanation:

The volume of the gas is directly proportional to the no. of moles of the gas at constant temperature and pressure.

So Volume of O2 : Volume of CO2 = 300: 200

= 3:2

So we can add 3 and 2 stoichiometric coefficients to O2 and CO2 respectively.

Then we can see that out of total 3×2 atoms of O, 2×2 atoms of O have been incorporated into CO2. Therefore the remaining 2 O should be in the H2O ( during complete combustion of hydrocarbon we get CO2 and H2O as products)

So we can add 2 in front of H2O..

Then calculate the total no. of C and H atoms in the products side to find the no. of C and H atoms in the hydrocarbon.

C=2

H=4

So the hydrocarbon burnt has the formula C2H4.

To solve such this we must know the concept of combustion reaction. Therefore, The balanced chemical reaction will be

C[tex]_2[/tex]H[tex]_4[/tex]+ 3O[tex]_2[/tex][tex]\rightarrow[/tex] 2CO[tex]_2[/tex] + 2H[tex]_2[/tex]O

What is chemical reaction?

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

Combustion reaction is a reaction in which a substance, basically hydrocarbons burns in presence of oxygen to produce carbon dioxide and water.

At constant temperature and pressure, the number of moles of the gas directly relates to the volume of the gas.

Volume of O[tex]_2[/tex]: Volume of CO[tex]_2[/tex]

= 300: 200

= 3:2

The chemical reaction will be

C[tex]_2[/tex]H[tex]_4[/tex]+ 3O[tex]_2[/tex][tex]\rightarrow[/tex] 2CO[tex]_2[/tex] + 2H[tex]_2[/tex]O

Therefore, the chemical reaction will be

C[tex]_2[/tex]H[tex]_4[/tex]+ 3O[tex]_2[/tex][tex]\rightarrow[/tex] 2CO[tex]_2[/tex] + 2H[tex]_2[/tex]O

n = 2 shell __
n = 2 l = 0 sub: __
n = 2 / 1 sub: __
3d sub: __
2s sub: __
5f sub: __

Answers

Explanation:

The maximum no. of electrons in a shell is given by. 2n^2 .

So for

n= 5 , 2× 5× 5 = 50

n=2 , 2×2×2 = 8

For a sub shell the maximum no. of electrons possible is given by 2(2l + 1)

So for n= l= 0

2 [(2×0) +1] = 2

for n=2 l=1

2 [(2×1) + 1] = 6

3d

d sub shell has l= 2 quantum number

Therefore 2[ (2×2) + 1] = 10

2s

s sub shell has l=0 quantum number

2 [(2×0) +1] = 2

5f

f sub energy level has l=3 quantum number

So 2[ (2×3) +1 ] = 14

The azimuthal quantum numbers for the sub shells are as follows

( s ---> 0

How does a phase change from solid to liquid occur in a substance?(1 point)

Answers

Answer:

As heat is added to solid water, the temperature increases until it reaches 0 °C, the melting point. At this point, the phase change, added heat goes into changing the state from a solid to liquid. Only when this phase change is complete, the temperature can increase.

hope this helps

Heat is responsible for the change of phase from solid to liquid state.

A phase change from solid to liquid occur in a substance by heating of that substance because the bonds present between solid particles can be broken down with the help of heat energy.

When the bond is heat at the temperature on which it is broken down, the solid particles are converted into liquid substance so we can conclude that heat is responsible for the change of phase from solid to liquid state.

Assume that 3.00 grams of HgO was used in this reaction. To determine the number of moles of oxygen gas formed, you need to know the number of moles of HgO reactant was used. What quantity in moles of HgO were used

Answers

Taking into account the reaction stoichiometry and the definition of molar mass, the quantity of HgO used is 0.01385 moles and 0.006925 moles of O₂ are formed when 3.00 grams of HgO was used.

In first place, the balanced reaction is:

2 HgO → 2 Hg + O₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

HgO: 2 molesHg: 2 molesO₂: 1 mole

The molar mass of the compounds is:

HgO: 216.59 g/moleHg: 200.59 g/moleO₂: 32 g/mole

You know that 3.00 grams of HgO was used. Then, the quantity in moles of HgO used, can be calculated using the molar mass of HgO as follow:

[tex]3 gramsx\frac{1 mole}{216.59 grams}[/tex]=  0.01385 moles

Finally, the quantity of HgO used is 0.01385 moles.

To determine the number of moles of oxygen gas formed, the following rule of three can be applied: if by reaction stoichiometry 2 moles of HgO form 1 mole of O₂, 0.01385 moles of HgO form how many moles of O₂?

[tex]amount of moles of O_{2} =\frac{0.01385 moles of HgOx1 mole of O_{2} }{2 moles of HgO}[/tex]

amount of moles of O₂= 0.006925 moles

Then, 0.006925 moles of O₂ are formed when 3.00 grams of HgO was used.

Answers

Answer: There are 36 valence electrons.

Explanation:

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the valence electrons of C₄H₈O₂ is 32.

What is element?

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

A valence electron is a negatively charged particle, located in the outermost shell of an atom, that can be transferred to or shared with another atom. To calculate total valence electrons in C₄H₈O₂, we need to add the individual valence electrons of each element.

Valence electrons of C₄H₈O₂= {valence electrons of C×4}+{valence electrons of H×4}+{valence electrons of O×2}

Valence electrons of C₄H₈O₂= {4×4}+{1×4}+{6×2}

Valence electrons of C₄H₈O₂=32

Therefore, the valence electrons of C₄H₈O₂ is 32.

4,756 rounded to nearest thousand

Answers

Answer:

5,000

Explanation:

When rounding to the thousands place, you look at the digit in the hundreds place, if the digit is less than 5 you round down. For example if the number was "4,456," we would round to "4,000." But, since the digit in the hundreds place is 7, which is greater than 4, you round up to "5,000."

Your answer will be 5,000 because 4,756 is 5000 rounded to the nearest THOUSAND. and the 7 is greater then 5 so you would make the 4 turn into a 5 and everything else goes to 0.

diagram 1 above shows equimolar samples of two gases inside a container fitted with a removable barrier placed so that each gas occupies the same volume. the barrier is carefully removed as the temperature is held constant. diagram 2 above shows the gases soon after the barrier is removed. which statement describes the changes to the initial pressure of each gas and the final partial pressure of each gas in the mixture and also indicates the final total pressure?

Answers

This problem is describing the state two gases have when separated and together as shown on the attached picture. First of all, diagram 1 shows how they are separated in two containers with apparently equal volumes, whereas diagram 2 shows the removal of the barrier so that they get mixed together.

In this case, we can analyze that each gas has its own pressure and due to the removal of the barrier, both pressure and volume undergo a change. Thus, we can infer that the final volume is doubled with respected to the initial one for each gas, causing the pressure of each gas to be halved and the total pressure the half of the added ones, in agreement to the Boyle's law (inversely proportional relationship between pressure and temperature).

Therefore, the correct choice is:

C. The partial pressure of each gas in the mixture is half its initial pressure; the final total pressure is half the sum of the initial pressures of the two gases.
