I think it’s A
because if the pH is lower than 7 than it is acidic
Answer:
If 1,079.75 Joules of heat are added to 77.75 grams of water, by 3.32 degrees Celsius the temperature of water will increase
Explanation:
Here , q = heat added / removed from the substance
m = mass of the substance taken
= Change in temperature
C = specific heat capacity of the substance
In liquid state the value of C for water is :
Given values :
q = 1079.75 J
m = 77.75 gram
Insert the value of C, m , q in the given equation
on transposing ,
The liter is the metric unit for volume. Branching off that are milliliters, deciliters, kiloliters, etc...
