Molar mass:
O2 = 31.99 g/mol
C8H18 = 144.22 g/mol
<span>2 C8H18(g) + 25 O2(g) = 16 CO2(g) + 18 H2O(g)
2 x 144.22 g --------------- 25 x 31.99 g
10.0 g ----------------------?? ( mass of O2)
10.0 x 25 x 31.99 / 2 x 144.22 =
7997.5 / 288.44 => 27.72 g of O2
hope this helps!

Answer:
1. Which people are in the control group? The people who received the mint without the secret ingredient
(Group B) would be the control group.
2. What is the independent variable? Secret ingredient in the breath mint
3. What is the dependent variable? Amount of breath odor (or bad breath)
4. What should Mr. Krabs’ conclusion be? The breath mint with the secret ingredient appears to reduce the
amount of breath odor more than half the time, but it is not 100% effective.
5. Why do you think 10 people in group B reported fresher breath? This may be due to the placebo effect.
A cherry red complexion would be the least trustworthy result when evaluating a client who had carbon monoxide poisoning suspicions.
Carbon monoxide poisoning:
- When present in sufficient quantity in the surrounding air, the odorless, colorless, and toxic gas known as carbon monoxide (CO) can result in rapid sickness and death. Using alternative fuels or electrical for warming, chilling, or cooking during power outages during situations like storms or winter storms can result in carbon monoxide(CO) buildup in a house, carport, or camper, which can harm the occupants and their pets.
- It is never a good idea to use a generator, grill, camp stove, or any other appliance that burns fuel, kerosene, natural gas, or charcoal inside a house, basement, garage, camper, or even outside next to an apartment window or windows air conditioner.
- Carbon monoxide poisoning can cause a variety of non-specific symptoms and indications. Migraine, vertigo, fatigue, vomiting, sickness, chest discomfort, and altered mental state are the most typical signs of CO poisoning.

False. carbon-carbon bonds that share 2 pairs of electrons are double bonds. An unsaturated hydrocarbon isnt necessary to only have double bonds. they can also have single bonds or triple bonds.
<h3>
Answer:</h3>
SrCO₃ + H₂SO₄ → SrSO₄ + H₂O + CO₂
<h3>
Explanation:</h3>
We are required to complete the chemical equation given;
strontium carbonate + sulfuric acid → ??
- We know that, carbonates reacts with acids to form a salt, water and carbon dioxide.
- Strontium carbonate reacts with sulfuric acid to form strontium sulfate, water and carbon dioxide.
- Therefore, the equation for the reaction is;
SrCO₃ + H₂SO₄ → SrSO₄ + H₂O + CO₂
- The equation is balanced as the number of atoms of each element are equal on both sides of the equation.
