Answer:

C. activates compounds for some reactions by transferring a phosphate group.

Explanation:

Adenosine triphosphate, also known as ATP, is an energy carrier molecule used by the cells of living organisms to carry out their cellular function. ATP has the peculiar ability to store and release energy needed to do work. This energy is stored when a phosphate molecule is added to ADP to form ATP while it is released when the last phosphate group is removed to form ADP.

ATP supplies energy to compounds by transferring one of its phosphate molecules to it in a process called PHOSPHORYLATION. This transfer causes the compound to be activated for the cellular process it is about to undergo.

How many milliliters of water will be created from a combustion reaction with 9.32×10 22nd power of ethanol molecules. Assume de

PolarNik [594]

Answer:

8.38 mL

Explanation:

1- The combustion reaction of ethanol (C2H5OH) in the presence of oxygen (O2) has as reaction products carbon dioxide (CO2) and water (H2O), the equation equaled is:

C2H5OH (l) + 3 O2 (g) CO2 2 CO2 (g) + 3 H2O (l)

2- By establishing the stoichiometric relationship between ethanol and water, you can calculate the number of molecules that will be created from the initial amount of alcohol molecules:

6,022x10 23 molecules of C2H5OH (1 mol) ___ 3 x 6,022x10 23 molecules of H2O (3 moles)

9.32x10 22 C2H5OH molecules _____ X = 2.80x10 23 H2O molecules

Calculation:

9.32x10 22 x (3 x 6.022x10 23) / 6.022x10 23 = 2.80x10 23 H2O molecules

3- Once the number of water molecules formed is obtained, with the molar mass the mass can be determined:

6.022x10 23 H2O molecules _____ 18.02 g

2.80x10 23 molecules of H2O _____ X = 8.38 g of H2O

Calculation:

2.80x10 23 x 18.02 g / 6.022x1023 = 8.38 g of H2O

4- Finally, having the density of water, you can calculate the volume that formed:

d = m / V --> V = m / d

V = 8.38 g / 1.00 mL = 8.38 mL

The answer is that 8.38 mL of water is formed

Compare and contrast the compositions of binary ionic and binary molecular compounds

ICE Princess25 [194]

Both are composed of two elements (that means binary).
Ionic is composed of two ions, metallic cation-positive ions, and nonmetallic anion - negative ions. For example NaCl (sodium-chloride).
Molecular compounds are composed of two nonmetallic elements. For example HCl (hydrochloric acid).

When the oxide of generic metal m is heated at 25.0 °c, only a negligible amount of m is produced. o2m(s ----> m(s o2(g delta

Len [333]

(1) MO₂(s) + C(s) → M(s) + CO₂ (g), ΔG₁ = 288.9 kJ/mol
(2) C(s) + O₂(g) → CO₂(g), ΔG₂ = -394.4 kJ/mol
By adding both equations 1 + 2 we get the coupled reaction:
MO₂(s) + 2 C(s) + O₂(g) → M(s) + 2 CO₂(g)
ΔG⁰ = ΔG₁ + ΔG₂
= 288.9 + (-394.4) = -105.5 kJ/mol = -105500 J/mol
Temperature T = 25 + 273.15 = 298.15 K
Molar gas constant R = 8.314 J/mol.K
K = $e^{ \frac{-dG0}{RT} }$
= $e^{ \frac{105500}{8.314 x 298.15} }$
= 3.05 x 10¹⁸
