Which best describes how heat energy moves within the system?

Chemistry

Radda [10]3 years ago

Heat can be transferred from one place to another by conduction in solids, convection of fluids like liquids or gases, and radiation. A temperature difference in a system causes heat to move from higher to lower temperatures

Answer: B

Heat always travels from warmer areas to cooler areas in the form of radiation or convection currents due to the temperature difference. You could kind of think of this movement like diffusion: travelling from a higher concentration to a lower one (if you take biology). This is how a gas heats up a pan on the stove or a radiator warms a room

Which of the following solutions has the HIGHEST hydroxide-ion concentration?a) 0.1 M HClb) 0.1 M H2SOc) a buffer solution with
Alexus [3.1K]

Answer:

c) a buffer solution with pH= 5

Explanation:

The equation of hydrolisis of water is:

1x10⁻¹⁴ = [H⁺] [OH⁻]

That means if we know [H⁺] we can find hydroxide-ion concentration and vice versa.

a) HCl 0.1M = [H⁺] = 0.1M;

1x10⁻¹⁴ / [H⁺]

1x10⁻¹⁴/ 0.1M = [OH⁻]

1x10⁻¹³M = [OH⁻] hydroxide- ion concentration.

b) 0.1M H₂SO₄ = 0.2M [H⁺]

1x10⁻¹⁴/ 0.2M = [OH⁻]

5x10⁻¹⁴M = [OH⁻]

c) pH = 5.

[H⁺] = 1x10⁻⁵M

1x10⁻¹⁴/ 1x10⁻⁵M = [OH⁻]

1x10⁻⁹M = [OH⁻]

d) pOH = 12.

[OH⁻] = 1x10⁻¹²M

That means risht answer is:

<h3>c) a buffer solution with pH= 5</h3>

Which of the following gases would be most likely to experience ideal behavior at high pressures?
monitta
<span>Which of the following gases would be most likely to experience ideal behavior at high pressures? 
a. F2 
b. Ne 
c. C2H6 

Yes. The answer is (b) Ne (Neon). This is because monoatomic gases such as neon do not experience </span><span>intermolecular attractions and thus most likely to be close to ideal gases behavior. Not only that, Neon is a noble gas and is unreactive. </span>

B. Calculate how many atoms of hydrogen are in 1. 75 moles of glucose (c6h12o6).
ycow [4]

Answer:

1.26x10^25 atoms of hydrogen

Explanation:

because there are 12 atoms of hydrogen in a molecule of glucose, multiply 12 by Avogadro's number (6.02x10^23) to get how many molecules of hydrogen there are in a mole of glucose. Then multiply that number by 1.75, which is the number of moles of glucose there is in this problem.
