Answer:

d. Form ATP during glycolysis.

Explanation:

During oxidative phosphorylation, an oxidation-reduction reactions will happen and the electrons transferred and energy released will be used in the conversion of adenosine diphosphate (ADP) into adenosine triphosphate (ATP).

This happens as a step of glycolysis, wich is the process in which the organism breaks gluscose molecules to obtain energy.

How many moles are in 2.4g of carbon dioxide (CO2)?
miv72 [106K]

Answer:

\boxed {\boxed {\sf 0.055 \ mol \ CO_2}}

Explanation:

To convert form grams to moles, the molar mass must be used. This is the mass (in grams) in 1 mole of a substance.

We can use the values on the Periodic Table. First, find the molar masses of the individual elements: carbon and oxygen.

  • C: 12.011 g/mol
  • O: 15.999 g/mol

Check for subscripts. The subscript of 2 after O means there are 2 oxygen atoms, so we have to multiply oxygen's molar mass by 2 before adding.

  • O₂: 2* (15.999 g/mol)=31.998 g/mol
  • CO₂: 12.011 g/mol + 31.998 g/mol =40.009 g/mol

Use the molar mass as a ratio.

\frac {44.009 \ g\ CO_2}{ 1 \ mol \ CO_2}

Multiply by the given number of grams.

2.4 \ g \ CO_2 *\frac {44.009 \ g\ CO_2}{ 1 \ mol \ CO_2}

Flip the fraction so the grams of carbon dioxide cancel.

2.4 \ g \ CO_2 *\frac { 1 \ mol \ CO_2}{44.009 \ g\ CO_2}

2.4  *\frac { 1 \ mol \ CO_2}{44.009}

\frac { 2.4 \ mol \ CO_2}{44.009}= 0.0545342998 \ mol \ CO_2

The original measurement of grams has 2 significant figures, so our answer must have the same. For the number we calculated, that is the thousandth place.

The ten thousandth place has a 5, so we round the 4 to a 5.

0.055 \ mol \ CO_2

2.4 grams of carbon dioxide is about 0.055 moles.

The lightest particle among the following is :
Triss [41]

The question is incomplete, the complete question is;

The lightest particle among the following is:

• Electron •Proton • Neutron • Alpha​

Answer:

Electron

Explanation:

There three basic subatomic particles are electrons, protons and neutrons. Both protons and neutrons are found in the nuclear and both contribute towards the mass of the atom. The alpha particle has the same mass as the helium nucleus.

However, the electrons are found in orbiit and have a negligible mass compared to the mass of the protons and neutrons. The mass of the electron is about 9.11 × 10^-31 Kg. This makes it the lightest of all the particles listed among the options.
