Answer:
The diagram is attached.
Explanation:
Peptide just refers to two or more amino acids liking together. A dipeptide consists of two amino acids linking together. A polypeptide is more that two amino acids linking together.
Answer:
Explanation:
Q = Ce . m .ΔT
Q : calor
Ce : calor especifico
m: masa
ΔT : variación de temperatura
capacidad térmica : 0,550 cal / °C
lectura :
por 1 °C se tiene 0,550 cal
por lo tanto tenemos datos de la temperatura y del calor
pero no olvidar las unidades en el sistema internacional :
Ce : J / kg . K
J: joules
kg: kilogramo
K: kelvin
pasar de gramos a kilogramos
pasar de calorías a joules
pasar de grado celsius a kelvin
1000g equivale a 1kg
15g equivale a 0,015 kg
K= °C + 273 ⇒ formula para pasar de grado celsius a kelvin
K= 1 + 273
K= 274
1 caloría equivale a 4,184 joules
0,550 caloría equivale a 2,3012 joules
ahora como todos los datos ya están en el S.I remplazamos en la formula
Q = Ce . m .ΔT
2,3012 = Ce . 0,015.274
Ce=0,5599 J / kg. K
Extensive properties, as volume and mass, depend on the amount of material. So, you can have a sample of gold and a sample of copper with the same volume as long as you have different amount of each one.
On the other hand, intensive properties do not depend on the amound of material but on the chemical constitution of the material. Density is an intensive property, so gold and copper have different densities. That is why you can use intensive properties to characterize different materials.
Answer:
Explanation:
In this case, we can start with the <u>formula of Platinum (II) Chloride</u>. The cation is the atom at the left of the name (in this case ) and the anion is the atom at the right of the name (in this case ). With this in mind, the <u>formula would be</u> .
Now, if we used <u>metallic copper</u> we have to put in the reaction only the <u>copper atom symbol</u> . So, we have as reagents:
The question now is: <u>What would be the products?</u> To answer this, we have to remember <u>"single displacement reactions"</u>. With a general reaction:
With this in mind, the reaction would be:
I hope it helps!
B. Two significant figures
Your final answer can only have as many significant figures as the number that has the least amount of significant figures in it, which is (0.0065)
