True. If the balanced chemical equation did not account for all of the atoms in a reaction, the reaction could not be used for any type of quantitative analysis. It would also not be really useful since it is supposed to show how the molecules interact and in what quantities.
Answer:
8.9 KJ
Explanation:
Given data:
Mass of strip = 251 g
Initial temperature = 22.8 °C
Final temperature = 75.9 °C
Specific heat capacity of granite = 0.67 j/g.°C
Heat absorbed = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 75.9 °C - 22.8 °C
ΔT = 53.1 °C
Now we will put the values in formula,
Q = 251 g × 0.67 j/g.°C × 53.1 °C
Q = 8929.8 J
Jolue to KJ conversion.
8929.8J ×1 KJ / 1000 J
8.9 KJ
Answer:
no, water is a solvent
Explanation:
A solution is a homogeneous mixture of two substances, so water can only be part of a solution when there is something (a solute) mixed with it, like salt, making it salt water.
Hope that helps.
We are given the mineral ilmenite with a molecular formula of FeTiO3. The molar mass of the compound is equal to 151.72 g/mol. The percent titanium thus is 31.55 percent.when 750 grams of titanium is present, the mass of ilmenite is equal to 2377.18 grams
