Answer:
1.395J/g°C
Explanation:
The following were obtained from the question:
Q = 6527J
M = 312g
ΔT = 15°C
C =?
Q = MCΔT
C = Q/MΔT
C = 6527/(312 x 15)
C = 1.395J/g°C
The specific heat capacity of the substance is 1.395J/g°C
the heat of reaction for a chemical reaction
Answer:
1.06L = V₂
Explanation:
Charle's Law states that the volume of a gas is directly proportional to the absolute temperature when pressure remains constant.
The equation is:
V₁T₂ = V₂T₁
<em>Where V is volume and T absolute temperature of 1, initial state and 2, final state of the gas.</em>
V₁ = 1.83L
T₂ = -100°C + 273.15 = 173.15K
V₂ = ?
T₁ = 27°C + 273.15 = 300.15K
V₁T₂ = V₂T₁
1.83L*173.15K = V₂*300.15K
<h3>1.06L = V₂</h3>
Answer:
<u>»</u><u> </u><u>Similarities</u><u> </u><u>:</u>
☑ They both react by chemical means, to produce either an element or compound as the end product of the chemical reaction.
• Take an example of Magnesium reacting with cold water:

• If it reacts with steam:

• [ Element: <em>Magnesium</em><em> </em>and Compound: <em>Water</em><em> </em>]
They are both classified under atomic substances cause they are made up of microscopic molecules known as atoms.
☑ They are both formed up by microscopic substances known as atoms.
<u>»</u><u> </u><u>Differences</u><u> </u><u>:</u>
☑ Compounds generally have higher molecular masses than elements.
☑ Compounds are formed through bonding by elements while elements can naturally exist or formed by extraction, purification and concentration
