<span> Ice was soon being harvested from contaminated water sources. Microbes in the ice invaded the food and people became ill
</span>so <span>unsanitary ice is your answer i hope this helps</span>
I am unsure if this is correct, but this might be the whole section:
- The top of the syringe is a circle. You need to compute its area for use in later computations of pressure values. Start by using a ruler to measure the diameter. Estimate to the nearest 0.01 cm. <em>Answer: </em><em>3.60 </em><em>cm</em>
- Divide by two to find the radius. Maintain significant figures. <em>Answer: </em><em>1.80 </em><em>cm</em>
- Substitute the radius into the formula A = πr² to find the area of the top of the syringe. Maintain significant figures. <em>Answer: </em><em>10.2 </em><em>cm²</em>
B The collisions of the particles are elastic
Combustion is the term used when something ignites
Neutralization is the term used when opposite pH acids and alkalis mix
Polymerization is the term used when monomers are chemically reacted to make polymers
Transmutation is the term used when an atom changes from one element to another
Answer:
222.91g of KCl
Explanation:
First, we need to write a balanced equation for the reaction. This is illustrated below
2K + Cl2 —> 2KCl
Molar Mass of KCl = 74.55 g/mol
Mass of KCl from the balanced equation = 2 x 74.55 = 149.1g
Molar Mass of Cl2 = 2 x 35.45 = 70.9g.
From the equation,
70.9g Cl2 produced 149.1g of KCl.
Therefore, 106 g of Cl2 will produce = (106 x 149.1)/70.9 = 222.91g of KCl
