Step 1: Define

[RxN - Balanced] C₁₂H₂₂O₁₁ + 12O₂ → 12CO₂ + 11H₂O + Energy

[Given] 448 g C₁₂H₂₂O₁₁ (sucrose)

[Solve] grams CO₂ (carbon dioxide)

Step 2: Identify Conversions

[RxN] 1 mol C₁₂H₂₂O₁₁ → 12 mol CO₂

[PT] Molar Mass of C - 12.01 g/mol

[PT] Molar Mass of H - 1.01 g/mol

[PT] Molar Mass of O - 16.00 g/mol

Molar Mass of C₁₂H₂₂O₁₁ - 12(12.01) + 22(1.01) + 11(16.00) = 342.34 g/mol

Molar Mass of CO₂ - 12.01 + 2(16.00) = 44.01 g/mol

Step 3: Stoich

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

When naming binary ionic compounds, name the non-metal anion first

When naming an ionic compound, the name of the metal comes first.

An ionic compound is composed of a metal and a nonmetal. Usually, the metal forms the positive ion while the nonmetal forms the negative ion.

When naming an ionic compound, the name of the metal is mentioned first followed by the name of the nonmetal.

For example, when naming an ionic compound that contains sodium and chlorine, the name is sodium chloride.

Answer:

65.8mL of water and 184.2mL of the 95% EtOH stock solution must be added.

Explanation:

To solve this question we need to find hoy many times the 95% EtOH must be diluted to obtain a 70% EtOH solution. That is:

95% / 70% = 1.357 times the solution must be diluted.

If we want to make 250mL of the diluted solution, the amount of 95% that must be added is:

250mL / 1.357 times =

184.2mL of the 95% solution must be added

And of water:

250mL - 184.2mL = 65.8mL of water

Answer:

Greater

Explanation:

This is because , 4 g of NH4NO3(s) contains more number of moles than 2 g of NH4NO3(s). Since the amount of heat (q, in J) released or absorbed for the dissolution is measured in kJ/mol, the higher the number of moles , the higher the amount of energy released. Since 4 g of NH4NO3(s) contains more number of moles than 2 g of NH4NO3(s), it will thus release or absorb more heat. So, the amount of heat is greater.

Since 4 g of NH4NO3(s) contains more moles than 2 g of NH4NO3(s), it will thus absorb more heat showing that the amount of heat is greater.

From the given information, we are to determine whether the amount of heat released or absorbed is greater or lesser.

Since 4 g of NH4NO3(s) contains more moles than 2 g of NH4NO3(s), it will thus absorb more heat showing that the amount of heat is greater.

Answer:

178.56 cm3

Explanation:

V1/T1=V2/T2

V2=V1T1/T2

V1 (volume) is 200 cm3

T1 (temperature) is 60°C but convert into Kelvin

T2 (temperature) is 100 °C but convert into Kelvin

Plug in the values...

V2= (200 cm3)(60+273.15)/ (100+273.15)

V2=178.56 cm3

Answer:

781×10¯² g of MgCl₂.

Explanation:

The balanced equation for the reaction is given below:

Mg + 2HCl —> MgCl₂ + H₂

Next, we shall determine the mass of HCl that reacted and the mass of MgCl₂ produced from the balanced equation. This is illustrated below:

Molar mass of HCl = 1 + 35.5

= 36.5 g/mol

Mass of HCl from the balanced equation = 2 × 36.5 = 73 g

Molar mass of MgCl₂ = 24 + (35.5×2)

= 24 + 71

= 95 g/mol

Mass of MgCl₂ from the balanced equation = 1 × 95 = 95 g

SUMMARY:

From the balanced equation above,

73 g of HCl reacted to produce 95 g of MgCl₂.

Finally, we shall determine the mass of MgCl₂ produced by the reaction of 6 g of HCl. This can be obtained as follow:

From the balanced equation above,

73 g of HCl reacted to produce 95 g of MgCl₂.

Therefore, 6 g of HCl will react to produce = (6 × 95)/73 = 781×10¯² g of MgCl₂.

Thus, 781×10¯² g of MgCl₂ were obtained from the reaction.

Answer:

6.83x10⁻⁴M is the initial concentration of the Cu²⁺

Explanation:

The concentration is directly proportional to the signal (Beer-Lambert law).

The increase in concentration produce an increase in signal of:

45.1 units - 25.2 units = 19.9 units.

The increase in concentration is of:

0.500mL = 5x10⁻⁴L * (0.0275mol / L) = 1.375x10⁻⁵moles / 0.0255L = 5.39x10⁻⁴M

The conversion factor is 5.39x10⁻⁴M = 19.9 units

That means the initial concentration that produce a signal of 25.2 units is:

25.2 units * (5.39x10⁻⁴M / 19.9 units) =

Answer: 4 miles

Explanation:

Riding the bike 12 mph (miles per hour) for one hour, we would ride the bike 12 miles. Since 20 minutes is 1/3 of a hour, divide 12 by 3 to find out how far the biker traveled in 1/3 of the time: 4 miles Hope this helps

Hello!

[tex]\large\boxed{\frac{5}{3}\text{ hours} \text{ or }100 \text{ min}}[/tex]

Use the equation d = s · t where:

s = speed

t = time

d = distance

Plug in the given distance and speed:

20 = 12 ·t

Divide both side by 12 to isolate for t:

20/12 = t

Simplify:

5 / 3 = t

Therefore, it took 5/3 hours to bike. We can convert this to minutes if necessary:

5/3 · 60 min (in one hour) = (60 · 5) / 3 = 100 min.

Answer:

Explanation:

Due to less predators in the Savannah/habitat, the population could unexpectedly grow. This will have an impact on the environment because it will give rise to more prey as there will be fewer predators. If too many herbivores are present on one feeding site, competition for food will occur. If there are more plants in an area than normal, it can increase the population of animals that consume the plant. If the population of one animal rises, the population of animals that consume that animal could also rise.

Population growth isn't always good. A population may often grow too big to sustain the climate. Other modifications in limiting variables can cause a population to decline. The population will decrease if a population becomes diseased, and the population of animals that consume the diseased animals will decrease as well. Populations in nature typically balance themselves. Sometimes, they can't always restore a natural balance as man affects populations.
