<span>The atoms in a compound are held together by a chemical bond. The chemical bonds can be either covalent bonds or ionic bonds. Both the bonds are considered very strong bonds. These bonds are mainly formed by sharing of electrons or in the case when one of the elements making the compound donates electron to the other element. The nucleus of each atom attracts to form a strong bond. This property of attraction between the nucleus of the atoms actually helps in forming the chemical bonds. </span>
The concept that can be used in order to answer this item is that of the conservation of heat among the system. We let T be equal to the final temperature. The equation that would allow us to relate the initial and final conditions of both substances is as follows,
m₁cp₁(T - T₁) = m₂cp₂(T₂ - T)
The first entity, 1, is the milk and the second entity, 2, is the coffee. We are given that the specific heats of both substances are just equal so we can eliminate them from the equation. Substituting the known values,
(10 g)(T - 10°) = (1.60 x 10^2 g)(90° - T)
The value of T from the equation is 85.29°C.
Answer: 85.29°C
Answer;
12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms.
Explanation:
Using a balanced chemical equation we can identify the number of carbon, hydrogen, and oxygen atoms in sugar.
CxHyOn + 12O₂ → 11 H₂O + 12CO₂
When an equation is completely balanced, then the number of each atom of an element is equal on the reactant side and the product side.
Therefore;
For carbon; x = 12
For Hydrogen; y = (11×2) = 22
For Oxygen; n + (12×2) = 11 + (12×2)
= n + 24 = 11 + 24
n = 11
Therefore the sugar has, 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms.
Thus the balanced equation would be;
C₁₂H₂₂O₁₁ + 12O₂ → 11 H₂O + 12CO₂
Answer: 1.21x10²³ formula units Ca( ClO3)2
Explanation: solution attached:
Convert mass of Ca(ClO3)2 to moles
Convert moles of Ca(ClO3)2 to formula units using Avogadro's number
The final temperature inside the container is 77.5°C
<h3>Solution ; </h3>
There are two heat transfers involved:
heat lost by bolt 1 + heat gained by bolt 2 = 0
-q(heat released by iron bolt) at higher temperature = q(heat gained by iron bolt) at lower temperature
-(cm)(T2-Treat higher temperature) = (cm)(T2-Tre at lower temperature)
-[0.450/(J/g-K) × m × (T2 -100°C)] = [0.450/(J/g-K) × m × (T2 -55°C)]
Or, -(T2 - 100°C) (T2 - 55°C) T2+T2 = 100°C + 55°C
Or, T2 = 155°C /2 = 77.5°C
<h3>What is Specific Heat ?</h3>
Specific heat is the amount of heat necessary to increase the temperature of one gram of a substance by one degree Celsius. Specific heat is often measured in calories or joules per gram per Celsius degree. Water, for example, has a specific heat of one calorie (or 4.186 joules) per gram per Celsius degree.
