and
quanitative data
Explanation:
hope this helps and PLZ brainliest thank you
1.25 Meters would be the answer.
This statement is: False
Boiling is vaporization that occurs both below and at the surface of the liquid.
However, evaporation happens at the surface of the substance.
So, if you need to correct this statement, the correction would be:
Sublimation and evaporation happen at the surface of the substance.
Answer:
The heat produced by this reaction is 2887J
Explanation:
The reaction of HCl with NaOH occurs as follows:
HCl + NaOH → H2O + NaCl + ΔH
<em>Where ΔH is released heat due the reaction</em>
<em />
The equation of a coffee cup calorimeter is:
Q = C*m*ΔT
<em>Where Q is heat produced, </em>
<em>C is specific heat of the solution (4.18J/g°C), </em>
<em>m is mass of the solution (50mL + 50mL = 100mL = 100g -Because density is 1g/mL) </em>
<em>and ΔT is change in temperature (28.9°C - 22.0°C = 6.9°C)</em>
<em />
Replacing:
Q = 4.184J/g°C*100g*6.9°C
Q = 2887J
The heat produced by this reaction is 2887J
