Question of the day

In the complete combustion of 44.0 grams of propane, how many grams of water are formed?

Explanation:
To determine how many grams of water are formed from the complete combustion of propane (C3H8), we need to first examine the balanced chemical equation for this reaction. The combustion of propane can be represented as follows: \[ \text{C}_3\text{H}_8 + 5\text{O}_2 \rightarrow 3\text{CO}_2 + 4\text{H}_2\text{O} \] From the balanced equation, we can see that one mole of propane produces four moles of water. Next, we need to calculate the moles of propane in 44.0 grams. The molar mass of propane (C3H8) is approximately 44.1 g/mol (calculating from the atomic masses of carbon and hydrogen, i.e., 12.01 g/mol for carbon and 1.008 g/mol for hydrogen). Thus, for 44.0 grams of propane: \[ \text{Moles of propane} = \frac{44.0 \text{ g}}{44.1 \text{ g/mol}} \approx 1.0 \text{ mol} \] According to the stoichiometry from the balanced equation,

About this course

Premium, focused exam preparation, built for results.

The ACT Science section tests your ability to interpret, analyze, evaluate, and reason through scientific information. It's designed to measure the skills you’ve developed over your high school years. Engaging with the ACT Science Practice Exam is a critical step in your preparation journey towards a higher score and securing your spot in your preferred college.

What to Expect on the ACT Science Exam

The ACT Science section is a 35-minute sprint with 40 questions designed to test your scientific reasoning skills. Unlike what the name may suggest, prior detailed knowledge of scientific content isn't the core requirement; instead, your ability to interpret data and scientific information is key.

The section presents several types of passages:

  • Data Representation: These consist of graphs, tables, and other figures, focusing on your ability to read and interpret scientific data.
  • Research Summaries: These involve descriptions of scientific experiments, challenging you to grasp the experimental processes and compare results.
  • Conflicting Viewpoints: These present several hypotheses or models and require you to understand, evaluate, and compare.

The exam isn't about memorizing facts but about thinking like a scientist.

Exam Format

  • Number of Questions: 40
  • Time Allotted: 35 minutes
  • Types of Passages:
  • 6-7 short passages
  • Combination of text and figures

The answers are multiple-choice, with four options per question, and your task is to choose the best possible answer. Unlike other sections of the ACT, this one allows calculators, though they are not as crucial as they are in the math section.

Essential ACT Science Strategies

Preparation is key to conquering the ACT Science section. Here are some effective strategies:

  • Familiarize Yourself with the Format: Understanding the types of passages and questions ahead of time will reduce surprises and anxiety.
  • Practice Interpreting Data: Since a significant portion of the test involves interpreting graphs and tables, regularly engaging in this practice through resources like Examzify can enhance your comfort level.
  • Time Management: With only 35 minutes, efficient time management is critical. Practice pacing yourself to ensure you can thoroughly engage with each passage.
  • Develop a Consistent Approach: Consider using a systematic approach for each passage, especially those that include multiple experiments or hypotheses. Having a plan can streamline your process under time constraints.
