Classify the following processes as exothermic or endothermic: (d) a person running;
Sonja [21]

The process releases energy and consequently we classify it as exothermic. (d) a person running releases warmness as muscle mass paintings. therefore, the procedure is exothermic.

d) Exothermic, heat is released as a person runs and muscle groups perform work.

A chemical response or bodily exchange is exothermic if warmth is released by using the system into the environment. Because the surroundings are gaining heat from the system, the temperature of the surroundings increases. The sign of q for an exothermic procedure is -ve due to the fact the device is dropping heat.

Some other examples of exothermic reactions:

1)Snow Formation in Clouds.

2)Burning of a Candle.

3)Rusting of Iron.

4)Formation of Ion Pairs.

5)response of strong Acid and Water. etc...

An object has a velocity of 8m/s and a kinetic energy of 480 j what is the mass of the object
MariettaO [177]
Kinetic energy=Ek
Ek=(1/2)mv²
Ek=480 J
v=8 m/s
mass=?

Ek=(1/2)mv²
480 J=(1/2)m(8 m/s)²
480 J=(32 m²/s²) m
m=(480 J)/(32 m²/s²)=15 kg

answer: the mass of the object is 15 kilograms.

How can we separate the components of a compound?
Alinara [238K]

Answer:

A mixture is a physical combination of substances thus it only requires physical processes to separate. However, a compound is chemically combined and can only be separated by chemical processes. Therefore, it is much harder to separate a compound than a mixture.
