Students pour some table salt into a beaker with distilled water to make a solution in order to test its conductivity. When they

placed a conductivity probe in the salt water solution, it measured a high conductivity. The students repeated the same procedure with white sugar and measured no conductivity. Which of the following statements best explains why sugar is not conductive in solution?

A sample of an unknown liquid has a mass of 21.09 g, and a volume of 6.44 ML. What is the density of this liquid?
Olenka [21]
Hey there!:

Mass = 21.09 g

Volume = 6.44 mL

Therefore;

Density = mass / Volume

Density = 21.09 / 6.44

Density = 3.274 g/mL

Given the following equation: 8Fe+S8=8FeS
maxonik [38]

Answer:

a. 2954g of FeS

b. 1143g of FeS

Explanation:

Based on the reaction:

8 Fe + S₈ → 8 FeS

<em>8 moles of Fe reacts with 1 mole of S₈ to produce 8 moles of FeS</em>

<em />

a. 4.2mol sulfur produce:

4.2mol S₈ × ( 8 mol FeS / 1 mol S₈) = <em>33.6mol FeS</em>. As molar mass of FeS is 87.92g/mol, mass is:

33.6mol FeS × ( 87.92g / 1 mol FeS) = <em>2954g of FeS</em>

<em />

b. 13mol Fe produce:

13mol Fe × ( 8 mol FeS / 8 mol Fe) = <em>13mol FeS</em>. In mass:

13 mol FeS × ( 87.92g / 1 mol FeS) = <em>1143g of FeS</em>

An experiment was performed to determine how the amount of coffee grounds could affect the taste of coffee.The same kind of coff
gavmur [86]
What we want to measure is the taste of coffee.

The following were kept constant during the experimental investigation:
The type of coffee,
The type of percolator,
The same amount and type of water,
The same perking time,
The same electrical sources.

Because these items were kept constant, they are not expected to influence the outcome of the experimental investigation.

Define:
y = the metric used to measure the taste of coffee
x = amount of coffee grounds used for the taste experiment.

Therefore the relationship that arises from the experiment is
y = y(x).

Because x is controllable and is varied during the experiment, it is the independent variable.
Because the measured value of y depends on x, therefore y is the dependent variable.

Answer:
The taste of coffee is the dependent variable.
The amount of coffee grounds used is the independent variable.
