Answer: This may result in the protein forming bonds with additional amino acids, this may result in the protein forming bonds with lipids instead of other proteins
Explanation:..
Answer:
D) burning a candle
A demonstration that contains both physical and chemical changes will be BURNING OF A CANDLE.
<em>This is because when a candle is lighted up, on the top of it (where we see flame) the oxygen and other gases present around will be chemically changed (burned up)</em>
<em>When the wax in the top of the candle will get melted due to the heat of the fire a physical change takes places.</em>
Answer:
The two that are true are, "this represents a pure compound in two different states" and "it represents a mixture a solid and a gas".
Explanation:
This two are concluded only from the picture and the use of uniform colors throughout the picture (Showing the same element).
2Al + 6H₂O ⇒ 2Al(OH)₃ + 3H₂
2mol : 2V
54g : 67,2L
268,5g : Vₓ
vₓ = 67,2dm³*268,5g / 54g ≈ 334,13L
Answer:
The answer to your question is Q = 640.5 J
Explanation:
Data
Volume of water = 15 ml
density of water = 1 g/ml
Temperature 1 = T1 = 25°C
Temperature 2= T2 = 35.2°C
Specific heat = 4.186 J/g°C
Process
1.- Calculate the mass of water
Mass = density x volume
= 1 x 15
= 15 g
2.- Substitution
Q = mC(T2 - T1)
Q = 15(4.186)(35.2 - 25)
-Simplification
Q = 15(4.186)(10.2)
-Result
Q = 640.5 J
