Jupiter Saturn Mars Earth Sun
Answer:
277.7 g of CO2
Explanation:
Equation of reaction
C13H18O2 + 11O2 ---> 13CO2 + 9H2O
From the equation of reaction
1 mole of ibuprofen produces 13 moles of CO2
Molar mass of ibuprofen is 206g
Molar mass of CO2 is 44g
13 moles of CO2 weighs 572g
Therefore, 100g of ibuprofen will produce (100×572)/206 of CO2
= 277.7g
Answer:
The answer is
<h2>0.07 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of metal = 5.11 g
volume = 71.46 mL
The density of the metal is
We have the final answer as
<h3>0.07 g/mL</h3>
Hope this helps you
Answer:
B) The tree-of-heaven is originally from China. It produces a chemical that prevents other plants from growing around it.
Explanation:
In ecology, a plant is said to be "INVASIVE" if it is FOREIGN or NON-NON-NATIVE to a particular region or area and also poses a great threat to the native species of that region. An invasive species, when introduced into a foreign habitat, heavily competes with the existing local species of that same habitat.
This is the case of the tree-of-heaven, which is originally from China. The tree produces a chemical that prevents other plants from growing around it. Note that this plant species is foreign to the Shenandoah National Park in Virginia as it originates from China. Likewise it harms the local or native species of the park by secreting a chemical that prevents other plants from growing around it. This characteristics portrays a plant that is INVASIVE.
Answer:
The mass of oxygen gas dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air is 0.04936 grams.
Explanation:
Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant =
= partial pressure of oxygen
We have :
Pressure of the air = P
Mole fraction of oxygen in air = 
= Henry's constant = 
Putting values in above equation, we get:
Moles of oxygen gas = n
Volume of water = V = 5 L
Mass of 0.001542 moles of oxygen gas:
0.001542 mol × 32 g/mol = 0.04936 g
The mass of oxygen gas dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air is 0.04936 grams.
