Not really sure abot the answer but it seems like
D is the answer
one more time im not really sure
Answer:
0.385 J/g°C
Explanation:
Using the following formula, the specific heat of an elemental substance can be calculated:
Q = m × c × ∆T
Where;
Q = quantity of heat (J)
m = mass (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
Based on the given information, Q = 1375J, m = 50g, initial temperature = 22.8°C, final temperature = 94.2°C, c =?
Q = m × c × ∆T
1375 = 50 × c × (94.2 - 22.8°C)
1375 = 50 × c × 71.4
1375 = 3570c
c = 1375/3570
c = 0.3851
c = 0.385 J/g°C
The answer for this one would be A because
Answer:
- Initial: forward rate > reverse rate
- Equilibrium: forward rate = reverse rate
Explanation:
2NO₂(g) → N₂O₄(g) Kc=4.7
The definition of <em>equilibrium</em> is when the forward rate and the reverse rate are <em>equal</em>.
Because in the initial state there's only NO₂, there's no possibility for the reverse reaction (from N₂O₄ to NO₂). Thus the forward rate will be larger than the reverse rate.
Moisturizing conditioners is used for hair that has been damaged by strong alkaline shampoos, chemicals or heat styling.
To enhance the feel, texture, look, and manageability of hair, hair conditioner is a cosmetic product for hair care. Its major objective is to lessen friction between hair strands so that brushing or combing may be done more easily and without risking scalp harm.
Electrostatic interactions allow the conditioner's components, particularly positively charged quaternary ammonium species like behentrimonium chloride or polymers referred to as Polyquaternium-XX, where XX is a random number, to adhere to the hair. Once linked, these substances have a variety of outcomes. Their extensive hydrocarbon backbone contributes to lubricating each hair follicle's surface, which lessens friction and makes combing easier.
