no sorry I don't know how to do it
C. C6H1206 because glucose is used to make ATP
<span>Barium lies in the second group of the periodic table. Elements in this group have two valence shell electrons. These elements have a tendency to produce cations since it is easier to lose the two electrons than to gain six. Now, out of the options, chlorine forms an anion. It is an element from group 7, meaning it exhibits a valency of -1. Therefore, in order to bond with Barium, two Chlorine atoms will be needed. <u>The second option is correct.</u></span>
The balloon will burst if the volume of the balloon is less than 1.68 L since 8 g of sodium bicarbonate produces 1.68 L of carbon dioxide gas.
<h3>What is the volume of carbin dioxude produced from the chemical reaction between sodium bicarbonate (baking soda) and vinegar?</h3>
The volume of carbon dioxide produced is obtained from the equation below:
1 mole of sodium bicarbonate reacts with one mole of acetic acid in vinegar to produce 1 mole of carbon dioxide.
The volume of 1 mole of carbon dioxide is 22.4 L
Moles of sodium bicarbonate in 8 g = mass/molar mass
molar mass of sodium bicarbonate = 106 g
moles of sodium bicarbonate = 8/106 = 0.075 moles
Moles of carbon dioxide produced = 0.075 moles
Volume of carbon dioxide = 0.075 × 22.4 = 1.68 L
Therefore, the balloon will burst if the volume of the balloon is less than 1.68 L.

Answer:
The heat produced by this reaction is 2887J
Explanation:
The reaction of HCl with NaOH occurs as follows:
HCl + NaOH → H2O + NaCl + ΔH
<em>Where ΔH is released heat due the reaction</em>
<em />
The equation of a coffee cup calorimeter is:
Q = C*m*ΔT
<em>Where Q is heat produced, </em>
<em>C is specific heat of the solution (4.18J/g°C), </em>
<em>m is mass of the solution (50mL + 50mL = 100mL = 100g -Because density is 1g/mL) </em>
<em>and ΔT is change in temperature (28.9°C - 22.0°C = 6.9°C)</em>
<em />
Replacing:
Q = 4.184J/g°C*100g*6.9°C
Q = 2887J
The heat produced by this reaction is 2887J
