How can quartzite be distinguished from quartz sandstone? A. The mineral compositions are different.

B. Quartzite is not granular, while sandstone is granular.

C. Quartz sandstone has undergone metamorphism, while quartzite has not.

D. A broken piece of quartzite will break through, not around, quartz sand grains.

Answers

D. A broken piece of quartzite will break through, not around, quartz sand grains.

Quartzite and quartz sandstone have the same chemical formula (SiO_2)

Quartzite is a metamorphic rock. Heat and pressure have compressed the sand into a strong network of interlocking quartz grains.

Quartzite is so tough that it breaks through the sand grains rather than around them as in sandstone.

Answer:

D. A broken piece of quartzite will break through, not around, quartz sand grains

Final answer:

The steps to conduct a scientific experiment include identifying variables, formulating a hypothesis, gathering materials, designing the experiment, executing the experiment, recording and organizing data, analyzing the data, writing a conclusion, and sharing the findings.

Explanation:

The subject question seeks to understand the procedural steps in conducting an experiment. Below is a brief rundown of the steps:

Identify the variables.
Write out your hypothesis in an if/then format.
Gather your materials.
Design the experiment: This is where you decide how to manipulate and measure the variables you identified.
Execute the experiment: Here you follow your experimental design and record results.
Record and organize data: After executing the experiment, ensure that you carefully record and neatly organize your data.
Analyze the data: Use appropriate statistical tools to interpret the data you have.
Write a conclusion: The conclusion should summarize the results of the experiment, supporting or disproving the hypothesis.
Communicate your results: It's crucial to share your findings with others in a report or presentation format.

A compound has 39 g of potassium and 78 g of selenium. What is the mass ratio of potassium and selenium in the compound

Answers

The mass ratio of potassium and selenium in the given compound is equal to 1 : 2.

What is the mass ratio?

The mass ratio also known as the percent composition by mass defines the proportion of a particular compound that consists of the constituent elements of that compound.

The percent composition by mass of a constituent element of a compound can be determined by the division of the mass of that element by the molar mass of the compound, followed by its multiplication by 100.

According to the law of constant proportion, a pure compound is always made up of the same elements combined together in a fixed proportion by weight.

Given the mass of the potassium (K) in the compound = 39 g

The mass of selenium (Se) in the compound = 78

The mass ratio of K and Se is 39 : 78

The simplest form of the ratio of potassium and selenium is 1 : 2.

Trejo reacts 5.0 moles of hydrochloric acid (HCI) with 1.5 moles of barium hydroxide (Ba(OH)2). Which reagent is the limiting reagent and which is in excess?

Answers

the balanced equation for the above reaction is as follows
Ba(OH)₂ + 2HCl ----> BaCl₂ + 2H₂O
stoichiometry of Ba(OH)₂ to HCl is 1:2
number of Ba(OH)₂ moles - 1.5 mol
number of HCl moles - 5.0 mol
limiting reactant is fully consumed during the reaction and amount of product formed depends on amount of limiting reactant present
excess reactant only a fraction of the amount present is used up in the reaction
if Ba(OH)₂ is the limiting reactant
if 1 mol of Ba(OH)₂ reacts with 2 mol of HCl
then 1.5 mol of Ba(OH)₂ reacts with 2 x 1.5 = 3.0 mol of HCl
but 5.0 mol of HCl is present and only 3.0 mol is required
therefore excess reagent is HCl and limiting reactant is Ba(OH)₂
