Answer:
ATP supply will reduced or decrease drastically
Explanation:
ATP will reduced because carbohydrates are energy given food. Chemical energy are in carbohydrates, therefore when the undergo digestion i.e breakdown of larger pieces into smaller pieces, it is broken down into glucose i.e energy is released. Therefore, if there is now carbohydrates, ATP supply will reduced and there won't be energy needed for different cellular metabolic activities. The breakdown of carbohydrate supply energy.

A 200.0-mL sample of helium gas is in a cylinder with a movable piston at 110 kPa and 275 K. The piston is pushed in until the sample has a volume of 95.0 mL. The new temperature of the gas is 310. K. What is the new pressure of the sample?
51.1 kPa
261 kPa
249 kPa
274 kPa
Answer:
P₂ = 261 KPa
Explanation:
Given data:
Volume of sample = 200 mL
Initial pressure = 110 KPa
Initial temperature = 275 K
Final volume = 95 mL
Final temperature = 310 K
Final pressure = ?
Solution:
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₂ = P₁V₁T₂ /T₁ V₂
P₂ = 110 KPa× 200 mL× 310 K /275 K × 95 mL
P₂ = 6820000 KPa / 26125
P₂ = 261 KPa

7. Calculate the average atomic mass of bromine. One isotope of bromine has an atomic mass of 78.92amu and a relative abundance of 50.69%. The other major isotope of bromine has an atomic mass of 80.92amu and a relative abundance of 49.31%.
Answer:
Average atomic mass = 79.9 amu.
Explanation:
Given data:
Average atomic mass of Bromine = ?
Atomic mass of 1st isotope = 78.92 amu
Relative abundance of 1st isotope = 50.69%
Atomic mass of 2nd isotope = 80.92 amu
Relative abundance of 1st isotope = 49.31%
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (50.69×78.92)+(80.92×49.31) /100
Average atomic mass = 4000.45 + 3990.16 / 100
Average atomic mass = 7990.61 / 100
Average atomic mass = 79.9 amu.
The image shows particles of salt dissolved in water.
How will the arrangement of salt particles most likely change?
Salt particles will move toward the left through diffusion.
Salt particles will move toward the left through active transport.
Salt particles will move toward the right through diffusion.
Salt particles will move toward the right through active transport.
Answer: Hope it may help you
Explanation:
Diffusion can be defined as the movement of particles from a region where there a more concentration of solute to the region having less concentration of the solute.
Here, the salt particles will move from right side of the box to the left side of the box.
This is because the right side has more particle and the left side has less particles so they will move towards the left side.

What Happens When extra Solute is added to unsaturated ,saturated and supersaturated solution
of water is 36.0 g. If any more NaCl is added past that point, it will not dissolve because the solution is saturated. If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated.
Arrange the following in order of increasing atomic radius: Mg, Na, P, Si, and Ar.
Answer:
Ar, P, Si, Mg, Na
Explanation:
Ar=106pm
P=107pm
Si=111pm
Mg=141pm
Na=166pm
Na>Mg>Si>P>Ar is the order of increasing atomic radius.
What are elements?Elements are the simplest substances which cannot be broken down using chemical methods.
Atomic radii vary in a predictable way along or across the periodic table. The atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus we can say that helium is the smallest element, and francium is the largest.
Ar=106pm
P=107pm
Si=111pm
Mg=141pm
Na=166pm
Hence, Na>Mg>Si>P>Ar is the order of increasing atomic radius.

write the correct representation of an element x which contains 12 electrons and 16 neutrons
Answer:
²⁸Mg
Explanation:
12 electrons means it is a Mg;
A typical Mg has 12 neutrons, but this has 16 hence it must be an isotope with 4 extra neutrons.
Calculate the number of moles of Na+ ions in 25g of sodium carbonate?
Explanation:
First, we need to calculate the number of moles of sodium carbonate we have in a 25 g sample. To calculate this, we will
find the molar mass of sodium carbonate (Na2CO3):
⇒ 2 × Molar mass of sodium + Molar mass of carbon + 3×molar mass of oxygen
⇒ 2 × 23 + 12 + 3 × 16
⇒ 46 + 12 + 48
⇒ 106g/mol
Thus, the molar mass of Na2CO3 is 106g/mol.
Therefore, number of moles = 25 ÷ 106
=> 0.2358 mol
Now, we know that every mole of Na2CO3 have 0.2358 moles of Na+ ions. Hence, total moles of Na2CO3 is 0.4716 moles
Number of ions present = 6.022 × 1023 × 0.4716 mol = 2.84 × 1023ions
The molar mass of sodium carbonate is 106 g/mol. One mole of sodium carbonate gives 2 Na+ ions. Thus number of moles in 25 g of sodium carbonate is 0.47 moles.
What is sodium ions?Sodium ion Na+ is formed by the lose of one electron from the sodium metal. Sodium has one valence electron and it will reacts with other atoms by donating this electron and gaining a positive charge.
The molecular formula of sodium carbonate is Na₂CO₃. Therefore, one mole of sodium carbonate will give two moles of Na+ ions. The molar mass of sodium carbonate is 106 g/mol.
The number of moles of 25 g of sodium carbonate is calculated as follows:
Number of moles = 25 /106
= 0.235 moles.
It is clear that one mole of Na₂CO₃ gives two moles of sodium ions.Then, number of moles of sodium ions given by 0.235 moles of sodium carbonate is calculated as follows:
number of moles of Na+ = 0.235 × 2
= 0.47 moles
Hence, the number of moles of Na+ ions produced by 25g of sodium carbonate is 0.47 moles.

which is not a redox reaction?
a. Formation of ammonium sulphate from ammonia and sulphuric acid
b. formation of nitrogen monoxide from ammonia
c. formation of sulphuric acid from sulphur
d. formation of zinc from zinc sulphide
help me please
Answer:
D. formation of zinc from zinc sulphide
Explanation:
A redox reaction could be explained as an artificial reaction in which electrons are moved between two reactants partaking in it. This substitution of electrons can be recognized by examining the variations in the oxidation states of the reacting classes. The generation of hydrogen fluoride is an illustration of a redox reaction. We can crack the reaction down to investigate the oxidation and loss of reactants.

Which of the following steps can be used to identify a single replacement reaction? (5
points)
O Check whether the products are salt and water.
O Check if the ions of two compounds exchange places.
o Check if one element replaces another element in a compound.
Check whether the reactants are an acid and a base.
Answer:
d
Explanation:
check if one element replaces another element in a compound
The single replacement reaction can be identified when there has been the replacement of one element with another element in the compound. Thus, option C is correct.
The replacement reaction can be defined as the reaction in which the highly reactive element replaced the low reactive element in the reaction and forms a compound.
The reaction has been given as:
X + AY [tex]\rightarrow[/tex] AX + Y
The X has been highly reactive than Y replaces Y in the compound and forms the compound AX.
The single replacement reaction can be identified when there has been the replacement of one element with another element in the compound. Thus, option C is correct.
