I hope this is right because i just took a chemistry mock exam
The element symbol on the periodic table indicate the states of matter
Answer:
403.3 kPa is the new pressure
Explanation:
This problem is solved by this formula:
P₁ . V₁ = P₂ . V₂
101kPa . 575 mL = P₂ . 144mL
(101kPa . 575 mL) / 144 mL = P₂
403.3 kPa = P₂
Living things are made of elements, especially C, H, O, N, P, and S. Living things are alive because of the chemical reactions that occur in their cells, such as cellular respiration and protein synthesis, among many others.
Answer:H20
Explanation:
because it is the base that contributes electrons
Answer : The heat of the reaction is -221.6 kJ
Explanation :
Heat released by the reaction = Heat absorbed by the calorimeter


where,
= heat released by the reaction = ?
= heat absorbed by the calorimeter
= specific heat of calorimeter = 
= change in temperature = 
Now put all the given values in the above formula, we get:


As, 
So, 
Thus, the heat of the reaction is -221.6 kJ
