The equilibrium constant Kc for the equation2H2(g) + CO(g) ⇌ CH3OH(g)is 35 at a certain temperature. If there are 3.21 ×10−2 mol
12345 [234]

Answer: the concentration of [CO]= 0.0532M

Explanation:

From The equation of reaction

2H2(g) + CO(g) ⇌ CH3OH(g)

Applying Kc= [CH3OH]/[H2]^2[[CO]

[CH3OH]= 0.00487

[CO]= x-0.00487

[H2]=(0.032-0.00487)^2=0.0271

Substitute into formula

Kc=[CH3OH]/[H2]^2[[CO]

35= 0.00487/(0.0271)^2(x-0.00487)

Simplify

x-0.00487=0.189

x= 0.00487+0.189=0.193moles

[CO]= n/C= 0.193/3.63= 0.0532M

If the bag was made from a metal (like sturdy aluminum foil), do you think it would lose its heat faster or slower than the plas
Luden [163]

I think it would lose its heat faster than the plastic bags because of higher conductivity feature.

<h3>What is conduction?</h3>

Conduction is the process in which heat or electricity is transmitted or transferred through the material of a substance without movement of the material.

We know that metals are good conductors so we can conclude that it would lose its heat faster than the plastic bags bof higher conductivity feature.

Use the drop-down menus to seled the correct responses to each question about ocean zones
chubhunter [2.5K]

Answer:

Intertidal zone

Neritic zone

Open-ocean zone

Note: the correct questions are found below;

In which zone do you find marshes and mangrove forests?

In which zone are plankton plentiful, providing plenty of food for the fish that live there?

In which zone would you find very little plant or animal life compared to other zones?

Explanation:

The intertidal zone, sometimes called the littoral zone, is the area of the marine shoreline that is exposed to air at low tide, and covered with seawater when the tide is high. Intertidal zonation refers to the tendency of plants and animals to form distinct communities between the high and low tide lines. Some microclimates in the littoral zone are moderated by local features and larger plants such as mangroves.

The neritic zone is the region of shallow water (200 meters depth) above the continental shelf where light penetrates to the sea floor.

Due to the abundant supply of sunlight and nutrients such as plankton in this zone, it is the most productive ocean zone supporting the vast majority of marine life.

The open oceans or pelagic ecosystems are the areas away from the coastal boundaries and above the seabed. It encompasses the entire water column and lies beyond the edge of the continental shelf. It extends from the tropics to the polar regions and from the sea surface to the abyssal depths.

50.0 mL of an HNo3 solution were titrated with 36.90 mL of a 0.100 M LiOH solution to reach the equivalence point. What is the m
sleet_krkn [62]
Answer: 0.0738 M

Explanation:


1) Chemical equation:

<span>HNO₃ + LiOH → LiNO₃ + H₂O
</span>

2) Mole ratios:

1 mol HNO₃ neutralizes 1 mol LiOH

3) Number of moles of H⁺ from HNO₃:

M = n / V ⇒ n = M × V = 0.050 liter × M

4) Number of moles of OH⁻ from LiOH

M = n / V ⇒ n = M × V = 0.03690 liter × 0,100 M

5) Equivalence point:

number of moles of H⁺ = number of moles of OH⁻

⇒ 0.0500 × M = 0.03690 × 0.100 

⇒ M = 0.03690 × 0.100 / 0.0500 = 0.0738 M
