Explanation:
1 calorie = 4.18J
800 kj = 800 × 1000
= 800000 j
800000 = 800000/ 4.18 calories
= 191387.5598 calories
= 1.9 × 10^5 calories
Answer:
9.54
Explanation:
Fr the question given above, the following data were:
Concentration of hydronium ion [H3O⁺] = 2.9x10¯¹⁰ M
pH =?
The pH of the solution can be obtained as follow:
pH = –Log [H3O⁺]
pH = –Log 2.9x10¯¹⁰
pH = 9.54
Thus, the pH level of the solution is 9.54
Temperature of somewhere.
Answer:
D. Supported by observations
Explanation:
Because theories change over time, they both need to be proven, they do not go off of consensus, but they do need to be supported by observations.
