Identify this reaction.
sp2606 [1]

C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O

is a combustion reaction

Explanation:

In a combustion reaction a chemical substance (usually organic substances) are reacted with oxygen to form the most stable oxides and heat.

CH₄ + 2 O₂ → CO₂ + 2 H₂O

In a double displacement reaction two compounds exchange elements.

AB + CD → AC + BD

In a decomposition reaction a compound is split into simpler substances.

AB →  A + B

In a synthesis reaction two elements are combined to form another compound. A + B → AB

In a single displacement reaction a compound exchange one of its elements.

AB + C → AC + B

If you needed to make 100 mL of a 0.2 M fruit drink solution from the 1.0 M fruit drink solution, how would you do it? (Hint: Us
grigory [225]

Answer:

We take 20.0 mL of the 1.0 M fruit drink solution and then add 80.0 mL of water to  make 100 mL of a 0.2 M fruit drink solution.

Explanation:

  • Using the rule that: the no. of millimoles of a solution before dilution is equal to the no. of millimoles of the solution after the dilution.

<em>(MV) before dilution = (MV) after dilution.</em>

M before dilution = 1.0 M, V before dilution = ??? mL.

M after dilution = 0.2 M, V after dilution = 100 mL.

<em>∴ V before dilution = (MV) after dilution / M before dilution </em>= (0.2 M)(100 mL) / (1.0 M) = <em>20.0 mL.</em>

<em>So, we take 20.0 mL of the 1.0 M fruit drink solution and then add 80.0 mL of water to  make 100 mL of a 0.2 M fruit drink solution.</em>

Carbon dioxide (CO2) is the gas that is mainly responsible for global warming (the greenhouse effect). The burning of fossil fue
Nesterboy [21]

Answer:

1.7\cdot 10^{15} g

Explanation:

Glucose reacts with oxygen do produce carbon dioxide and water:

C_6H_12O_6 (s) + 6 O_2 (g)\rightarrow 6 CO_2 (g) + 6 H_2O (l)

Given a daily mass of glucose:

m_1 = 5.0\cdot 10^2 g

Find moles of glucose:

n_1 = {5.0\cdot 10^2 g}{180.156 g/mol} = 2.775 mol

From stoichiometry of this equation, moles of carbon dioxide can be found by multiplying this amount by 6:

n_2 = 2.775 mol\cdot 6=16.65 mol

Convert this into mass using the molar mass of carbon dioxide:

m_2 = 16.65 mol\cdot 44.01 g/mol = 732.8 g

This is the mass of carbon dioxide per person per day. Multiply by the population and by the number of days to get the total mass:

732.8 \frac{g}{person\cdot day}\cdot 365 days\cdot 6.5\cdot 10^9 people = 1.7\cdot 10^{15} g
