<h3><u>Answer;</u></h3>

10.80 ° C

<h3><u>Explanation;</u></h3>

From the information given;

Initial temperature of water =  24.85°C

Final temperature of water = 35.65°C

Mass of water = 1000 g

The specific heat of water ,c = 4.184 J/g °C.

The heat capacity of the calorimeter  = 695 J/ °C

Change in temperature ΔT = 35.65°C - 24.85°C

                                             = 10.80°C

Western regions Facts
babunello [35]
This region has both the state with the smallest population (Wyoming) and the largest population (California).
Alaska's land area is much bigger than any other state, but it has one of the lowest populations.
The western US takes up about half of the land of the United States.

The western United States is the region comprising the westernmost states of the United States. As American settlement in the U.S. expanded westward, the meaning of the term the West changed. Before about 1800, the crest of the Appalachian Mountains was seen as the western frontier.


Hope this helps :)

Sodium bicarbonate is sometimes used to neutralize acid spills. If 2.0 L of 1.0 M H2SO4 is spilled, what mass of sodium bicarbon
UkoKoshka [18]

Answer:

168.0 g

Explanation:

First thing, write a balanced chemical equation:

H_{2}SO_{4}+ 2NaHCO_{3}  ----> Na_{2}SO_{4} + 2H_{2}O+2CO_{2}

n(H2SO4) = concentration * volume

                = 1.0 M * 2.0 L

                = 2.0 mol

According to the balanced equation, 1 mol of acid requires 2 mol of sodium bicarbonate. This means that 2 mol of acid requires 2 mol of sodium bicarbonate. What mass of sodium bicarbonate is this?

mass (NaHCO3) = number of moles * molar mass

                           = 2.0 mol * 84.0065 g/mol

                           = 168.0 g
