Stoichiometry is the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers. Hoped this helped!!!!. Also if you are trying to look for the formulas it should be online just type in stoichometry formulas.
Answer:
168.56 mL
Explanation:
density = mass/volume, use basic algebra skills to replace the volume and solve
Answer:
7.59°C
Explanation:
Using the formula;
Q = m × c × ∆T
Where;
Q = amount of heat (joules)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
According to this question;
m = 80g
c = 4.2 J/g°C.
Q = 2550J
∆T = ?
Using Q = m × c × ∆T
∆T = Q/mc
∆T = 2550 ÷ (80 × 4.2)
∆T = 2550 ÷ 336
∆T = 7.589°C
The change in temperature of water = 7.59°C.
