There are 0.109 moles of NaCl in one tablespoon of salt. This is found by dividing the number of grams you have by the molecular weight.
Answer:
Measure the pH of different household chemicals
Explanation:
To demonstrate a chemical property using an experiment, measuring the pH of different household chemicals will be the best way. The pH is the degree of hydrogen or hydroxyl ion concentration in a solution.
Chemical properties tell us about what a substance can do.
It shows if a substance will react with other substances or not.
Examples are flammability, rusting of iron, precipitation, decomposition of water by electric current e.t.c.
Measuring the pH is a chemical property determination procedure.
The pH points to the degree of acidity or alkalinity of a solution.
The substance should be in liquid state.
First, it takes up space in the container, which leads to that it shouldn't be a solid, because solid doesn't change its shape easily.
Second, it has a fixed volume, it's difficult to compress the substance, therefore it shouldn't be gas too, as gas can be compressed easily.
Therefore we're left with liquid. And both of these given properties fits the property of liquid.
B) is a right answer because molar mass equal molecular atomic mass meaning Ar(Na)=23 and so M(Na)=23 as well.
Answer:
The answer is silicon.
