Answer:
Amount of heat required = 2810.5 J
Explanation:
Given data:
Mass of copper = 29.2 g
Initial temperature = 25°C
Final temperature = 275°C
Amount of heat required = ?
Solution:
Specific heat capacity of copper is 0.385 j/g.°C.
Formula:
Q = m×c×ΔT
ΔT = 275°C - 25°C
ΔT = 250°C
Q = 29.2 g × 0.385 j/g.°C ×250°C
Q = 2810.5 J
Answer:
2N2H2SO4
Explanation:
this is your answer calculate
To have a PH of 3, it means that the substance must be acidic since a PH of less than 7 less means that the tested substance is acidic. If the PH is greater than 7 then it will be a base or the opposite of acidic. PH of a solution can be tested with litmus paper ie qualitatively to see if it is an acid or a base. Aof an example of a base is NaOH sodium hydroxide and of an acid is H2SO4 or sulfuric acid.
Photorespiration is a process where the enzyme RuBisCO generates RuBP. It is also known as oxidative photosynthetic carbon cycle. This is a process where addition of carbon dioxide takes place in the RuBP.
In this process "two" molecules of RuBP are oxygenated for each molecule of CO2 that is released by photosynthesis.
