First, explain how water gets warmed with the POW Kit, why following the instructions is important, and how failure to follow the instructions could lead to problems.

Next, write a scientific argument that addresses the question: Why wasn’t the water pasteurized?

First, state your claim.

Claim 1: If you follow the instructions, the POW kits will always heat the water above the correct temperature for pasteurization (65°C), but some people didn’t follow the instructions.

Claim 2: Even if you follow the instructions, the POW kits will not heat the water above the correct temperature for pasteurization (65°C).

Then, use evidence to support your claim.

For each piece of evidence you use, explain how it supports your claim.

when 25.0 ml of 0.700 mol/l naoh was mixed in a calorimeter with 25.0 ml of 0.700 mol/l hcl, both initially at 20.0 °c, the temperature increased to 22.1 °c. the heat capacity of the calorimeter is 279 j/°c.

the equation for the reaction is:

naoh + hcl → nacl + h₂o

moles of hcl = 0.0250 l hcl ×

1 l hcl = 0.0175 mol hcl

volume of solution = (25.0 + 25.0) ml = 50.0 ml

= (22.1 – 20.0) °c = 2.1 °c

the heats involved are
