Answer:
Matter is everything that surrounds us. It has mass and occupies a place in space. Matter can be described by measuring the value of its properties; for example: density, color, mass, volume, etc.
al ser homogenea no se puede percibir con la vista pero si se le agrega acido sulfurico la reaccion hara que el hidrogeno y el oxigeno se evaporen dejando unicamente una masa negra de carbono
No, ya que, es una mezcla homogénea, es decir, sus elementos están muy unidos mas no combinados de manera química, es posible separarlos pero con mucha dificultad, por tanto, es imposible diferenciarlos a simple vista. Se sabe que están distribuidos de manera uniforme, su estado es conocido como solución o disolución, tal como es el caso del azúcar.

<span>Nuclear power plants produce radioactive
waste that must be stored properly. It is very impossible for a nuclear power plant
to have no waste at all since lots of chemicals are used to create the process
as it gives energy to other machines. Nuclear energy can be used to power all
of the above choices. Radioactive waste can not be released into local water
supplies since the wastes are very radioactive and may cause mutation to the
fishes and bioaccumulation which will affect humans as well. It will also cause
air pollution if the chemicals are not stored properly.</span>

Answer:
a)q= 2800 W/m²
b)To=59.4°C
Explanation:
Given that
L = 10 mm
K= 20 W/m·K
T=30°C
h= 100 W/m²K
Ti=58°C
a)
Heat flux q
q= h ΔT
q= 100 x (58 - 30 )
q= 2800 W/m²
b)
As we know that heat transfer by Fourier law given as
Q= K A ΔT/L
Lets take outer temperature is To
So by Fourier law
To= Ti + qL/K
Now by putting the values
To= Ti + qL/K
To=59.4°C
