To answer your question, the answer is number 1. hope this help
Answer:
mCO2= 49.6932 kgCO2
Explanation:
Hello! Let's solve this!
First we propose the balanced equation C3H8 + 5O2 ---> 3CO2 + 4H2O
We see that each mole of C3H8 (propane) we get 3 moles of CO2
From the propane volume we can obtain the grams of propane used.
molpropane = 26.5L * (1000mL / 1L) * (0.621g / 1mL) * (1mol / 44g) = 374.01mol propane
mCO2 = 374.01molC3H8 * (3molCO2 / 1molC3H8) * (44gCO2 / 1molCO2) = 49369.32g * (1kg / 1000g) = 49.6932 kgCO2
mCO2= 49.6932 kgCO2
The larger the piece the longer it will take to break down. This is because it has more mass that needs to be broken down. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
The name and chemical symbol of the elements are
- Carbon = C
- Lead = Pb
- Antimony = Sb
- Sodium = Na
- Aluminum = Al
<h3>What are chemical symbols?</h3>
Chemical symbols are which are used to represent the elements in the periodic table.
The chemical symbol assigned to elements are usually an abbreviation of the name of the element or the Latin form of the name.
The name and symbol of the given elements are as follows:
- Carbon = C
- Lead = Pb
- Antimony = Sb
- Sodium = Na
- Aluminum = Al
The chemical symbols are used frequently in writing the formula of compound formed from the elements. For example, the compound sodium aluminate which contains sodium, aluminum and oxygen is written in a simplified form as: NaAlO₂.
