Cual es el calor específico de una sustancia que tiene una masa de 15 g y una capacidad térmica de 0.550 calC
mr Goodwill [35]

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

What is the oxidation number for iodine in Mg(IO3)2 ?
navik [9.2K]
The oxidation number of iodine is 5 in Mg(IO3)2 which can be calculated as 
   Mg(IO3)2
   MgI2O6
As we know that
Mg has +2
O has -2
So,
   (+2) + 2I + 6 (-2)=0
   2 + 2I - 12 =0
   10+ 2I =0
    10 = 2I
     I =5

1. Alexa and her family travelled 5 hours south east on 1-45 to crystal
Gre4nikov [31]

Answer:

Average speed  = 68 mph

Explanation:

Given that,

Total distance traveled by the family, d = 340 miles

The family traveled 5 hours southeast.

We need to find her average speed. The speed of an object is given by the total distance covered divided by time taken. So,

v=\dfrac{d}{t}

Put all the values,

v=\dfrac{340}{5}\\\\v=68\ mph

So, her average speed is equal to 68 mph.
