Answer:
125cm^3
Explanation:
A cube has a side that is 5cm long, and a cube has all even sides. To determine the volume, you need to multiply the length, width, and height. Because all these numbers are 5, you do 5*5*5, or 5^3 power, which is 125
Answer:
Is pink in base solution, it provides a visual signal that a solution has changed from acid to a base, is colorless in acid solution.
Explanation:
As all the indicator, phenolphtalein has the property that turns pink when the solution that you have reaches a value of a pH of 9 or above. From 0 to 8 in a pH scale, is colorless. This point in which an indicator changes is it called equivalence point.
Protium - the most common isotope of hydrogen - has no neutrons in its nucleus.
Answer:
H = 4,034,250 J
Explanation:
Mass, m = 165kg = 165,000g (Converting to grams)
Initial temperature = 15.7°C
Final temperature = 95.7°C
Temperature change, ΔT = 95.7 - 15.7 = 50°C
Specific heat capacity, c = 0.489 J/g·°C
Heat = ?
All the parameters are related with the equation below;
H = m * c * ΔT
H = 165000 * 0.489 * 50
H = 4,034,250 J
Each state is allocated a number of electors equal to the number of its U.S. Senators
