Sodium carbonate (Na2CO3) reacts with acetic acid (CH3COOH) to form sodium acetate (NaCH3COO), carbon dioxide (CO2), and water (H2O). A chemist carries out this reaction in a bomb calorimeter. The reaction causes the temperature of a bomb calorimeter to decrease by 0.985 K. The calorimeter has a mass of 1.500 kg and a specific heat of 2.52 J/g•K. What is the heat of reaction for this system?

=3,723.3 J=3.72  but if it has the option of -3.72 kJ then use that

Explanation:

Use the formula q=m×Cp×delta T

m=1.500 kg=1,500 g

Co=2.52 J/g·k

delta T=0.985k

q=(1,500g)(2.52 J/g·k)(0.985k)

i can ! i just need to know what the paragraph is! : p

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
