40 g of NaCl is added to 1500 g of water. What is the molality of the resulting
solution?
Answers
Molality = moles of solute/mass (in kg) of solvent
The solute here is NaCl, of which you have 40 g or 40/58.4428 = 0.6844 moles NaCl.
The solvent here is water, of which you have 1500 g or 1.500 kg H2O.
The molality of the resulting solution would thus be 0.6844 moles NaCl/1.500 kg H2O = 0.4562 mol/kg.
If you have to consider sig figs, then your final answer would have one sig fig (40 g has one sig fig). In that case, your final answer would be 0.5 mol/kg.
The value of Kp for the reaction 2 A(g) + B(g) + 3 C(g) → 2 D(g) + E(g) is 18530 at a particular temperature. What would be the value of Kp for the reaction 2 D(g) + E(g) → 2 A(g) + B(g) + 3 C(g)?
Answers
Answer:
[tex]Kp2=5.3967x10^{-5}[/tex]
Explanation:
Hello there!
In this case, since the Kp for the first reaction is given, according to the following equilibrium expression:
[tex]Kp=\frac{p_D^2p_E}{p_A^2p_Bp_C^3} =18530[/tex]
However, since the second reaction stands for the reverse of the initial one, the equilibrium expression would be:
[tex]Kp_2=Kp=\frac{p_A^2p_Bp_C^3}{p_D^2p_E}[/tex]
And therefore its Kp the inverse of the aforementioned one:
[tex]Kp2=1/18530\\\\Kp2=5.3967x10^{-5}[/tex]

Briefly describe each of the suns layers. I’ll give brainless
Answers
Answer: The inner layers are the Core, Radiative Zone and Convection Zone.
The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona.
Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.
The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more.
The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the chromosphere varies between about 4000 K at the bottom (the so-called temperature minimum) and 8000 K at the top (6700 and 14,000 degrees F, 3700 and 7700 degrees C), so in this layer (and higher layers) it actually gets hotter if you go further away from the Sun, unlike in the lower layers, where it gets hotter if you go closer to the center of the Sun.
The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. The temperature in the photosphere varies between about 6500 K at the bottom and 4000 K at the top (11,000 and 6700 degrees F, 6200 and 3700 degrees C)

what is the function of a prism
Answers
Answer:
Prisms are sometimes used for the internal reflection at the surfaces rather than for dispersion. If light inside the prism hits one of the surfaces at a sufficiently steep angle, total internal reflection occurs and all of the light is reflected.
Explanation:
Prism, in optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light. An ordinary triangular prism can separate white light into its constituent colours, called a spectrum.

What is metal ? Where does it coke from ?
Answers
Answer:
Most pure metals, like aluminium, silver and copper, come from the Earth's crust. They are found in ores – solid materials called minerals, usually occurring in rock, from which the pure metal has to be extracted. The properties of pure metals can be improved by mixing them with other metals to make alloys.a metal is an element that readily forms positive ions (cations) and has metallic bonds

2KCIO3 -> 2KCI+ 302
How many moles of oxygen are produced by
the decomposition of 6.0 moles of potassium
chlorate, KCIO3?
Answers
Answer:
9 moles
Explanation:
The balanced chemical equation for this decomposition reaction is as follows:
2KCIO3 → 2KCI+ 302
Based on this equation, 2 moles of potassium chlorate (KCIO3) decomposes to form 3 moles of oxygen gas (O2).
Hence, 6 moles of pottasium chlorate will decompose to produce;
6 × 3 ÷ 2
= 18 ÷ 2
= 9 moles of O2.

Many ski resorts and mountain cities can be reached directly by planes which deposit travelers a mile or more above sea level. This can result in altitude sickness due to hypoxemia, or reduced oxygen in the blood, caused by the unaccustomed exposure to the lower atmospheric pressure at high elevations. On a given day, the prevailing atmospheric pressure in Albuquerque, NM (elevation 1620 meters) might be 0.799 atm. Calculate this pressure expressed in mmHg and in torr. Relationship between altitude and barometric pressure.
Answers
Answer:
See explanation
Explanation:
To convert from atm to mmHg
1 atm = 760 mmHg
0.799 atm = 0.799 atm * 760 mmHg/1 atm = 607.24 mmHg
To convert from atm to torr
1 atm = 760 torr
0.799 atm = 0.799 atm * 760 torr/1 atm = 607.24 torr
