Answer:

Reactants

Explanation:

A combination reaction is usually defined as a type of chemical reaction in which two or more reactants are fused together to form a single product. For example, The two elements Hydrogen and Chlorine are linked together to form Hydrochloric acid.

This can be written as,

H + Cl -----> HCl (acid)

A decomposition reaction is usually defined as a type of chemical reaction in which a single and complex substance is disintegrated into two or more simple substances. For example, the same above reaction can be disintegrated into-

HCl (acid) ------> H + Cl

Describe the general characteristics of the nearest stars. (Size, luminosity, color, etc., do not include specific stars)
Darina [25.2K]

Answer: The five general characteristics of the nearest stars are the brightness, color, surface temperature, size, and mass.

Explanation:

The mass of a star can be described as being measured with our sun at 1 solar mass. One star can equal the size of our sun. There is one star named, Rigel, that is bigger than the Earths sun. Each star will vary in its density.

The size of the star, as stated above, can be the size of our sun and sometimes larger. The size is measured by solar radii.

Stars vary in their temp. They range anywhere from -273.15 degrees Celsius to 50,000 K. The temp is based on the Kelvin scale.

The stars brightness are always based on luminosity and magnitude.

The stars colors will vary and is based on the temperature of the surface of the star. Some stars are red in color, white in color, and some even have a bluish color.

If a particle with a charge of +4.3 × 10−18 C is attracted to another particle by a force of 6.5 × 10−8 N, what is the magnitude
AveGali [126]

Answer: 1.5×10^10 N/C

Explanation:

E= F/q

Where E= magnitude of the electric field

F= force of attraction

q= charge of the given body

Given F= 6.5×10^-8 N

q= 4.3× 10^-18 C

Therefore, E = 6.5×10 ^-8/ 4.3×10^-18

E = 1.5×10^10 N/C

12. A frain moves from rest to a speed of 25 m/s in 30.0 seconds. What is its acceleration?
ziro4ka [17]
  • initial velocity=u=0m/s
  • Final velocity=v=25m/s
  • Time=t=30s

\\ \tt\longmapsto Acceleration=\dfrac{v-u}{t}

\\ \tt\longmapsto Acceleration=\dfrac{25-0}{30}

\\ \tt\longmapsto Acceleration=\dfrac{25}{30}

\\ \tt\longmapsto Acceleration=0.8m/s^2
