Explain why two thin sweaters feel warmer then one thick sweater​

Chemistry

Answer: Two thin woolen sweaters are warmer than a thick woolen sweater because there is a layer of air between them that doesn't allow our body heat to escape but it also it doesn't absorbs heat from the atmosphere and wool is also an insulator that itself doesn't allow our body heat to escape.

Answer:

Because there's two of them

Explanation:

The two sweaters trap a pocket of air that can't escape, making you warmer.

Read the passage below about acupuncture.
valkas [14]
The answer would be "This ancient form of pain relief and stimulation is said to benefit patients by blocking channels which practitioners claim allowed pain to travel within the body" because this statement best explains how acupuncture reduces pain.

To support such answer, it must be noted that acupuncture is a traditional Chinese mode of pain-relieving through the insertion of extremely fine needles into the skin at specific points in the body known as "acupoints". This may relieve pain by releasing the hormone known as endorphins (happy hormone), which is the body's natural pain-killers and by affecting the brain part that governs serotonin- brain chemical which involved mood.

If the composition of the reaction mixture at 400 k is [brcl] = 0.00415 m, [br2] = 0.00366 m, and [cl2] = 0.000672 m, what is th
Scorpion4ik [409]
Q is unlike K value it describes the reaction that is not at equilibrium.
by considering this reaction:
aA+ bB⇄ cC
and our reaction is:
Br2 + Cl2 ⇄ 2 BrCl

According to Q low:
Q= concentration of products/concentration of reactants
but this equation in the gaseous or aqueous states only.
∴ Q = [BrCl]^2 / [Br2] [Cl2]

and we have [Br2] = 0.00366 m  [Cl2]= 0.000672 m  [BrCl] = 0.00415 m

by substitution:
                          = [0.00415]^2 / ( [0.00366] * [0.000672])
             ∴   Q   = 7

A 63.5 g sample of an unidentified metal absorbs 355 ) of heat when its temperature changes
insens350 [35]

0.208 is the specific heat capacity of the metal.

Explanation:

Given:

mass (m)  = 63.5 grams 0R 0.0635 kg

Heat absorbed (q) = 355 Joules

Δ T (change in temperature) = 4.56 degrees or 273.15+4.56 = 268.59 K

cp (specific heat capacity) = ?

the formula used for heat absorbed  and to calculate specific heat capacity of a substance will be calculated by using the equation:

q = mc Δ T

c = \frac{q}{mΔ T}

c = \frac{355}{63.5X 268.59}

 = 0.208 J/gm K

specific heat capacity of 0.208 J/gm K

The specific heat capacity is defined as  the heat required to raise the temperature of a substance which is 1 gram. The temperature is in Kelvin and energy required is in joules.

Neko [114]

Answer:

a. The atom will go from a two-dimensional configuration to a three dimensional configuration.

d. The bond angle will increase.

f. The number of unhybridized p orbitals will decrease.

Explanation:

Sp2 is the atomic bond in which orbitals mixes with only two orbitals. These orbitals form three sp2. When two carbon atoms are overlapped they form sigma bond by overlapping of sp2 bonds. Sp3 bond is created when there is one lone molecule available for combination. When the bonding is updated from sp2 to sp3 then unhybridized orbitals will decrease causing the bond angle to increase.
