The correct answer is D..
No. Chemical compounds are seldom similar to the elements they're made of.
Here is another example to think about:
<em><u>Sodium</u> . . .</em>
a soft, silvery-white, highly reactive metal;
If exposed to air, the surface rapidly tarnishes and turns dark.
It reacts with water, to the point that a large piece in water may explode.
<em><u>Chlorine</u></em> . . .
a pale yellow-green gas at room temperature;
a strong bleach and disinfectant;
in the upper atmosphere, responsible for ozone depletion;
extremely dangerous and poisonous for all living organisms;
used in World War I as the first chemical warfare agent;
<em><u>Chemical compound of sodium and chlorine</u> . . .
</em>not a highly reactive metal
does not tarnish and turn dark when exposed to air
does not explode in water
not pale yellow-green<em>
</em>not a gas at room temperature
not useful for bleach or disinfectant
not responsible for ozone depletion
not dangerous or poisonous for living organisms
never used as a chemical warfare agent
chemical name: "sodium chloride"
common name: "salt"
widely used in cooking and eating, to season food
Answer:
Developmental psychologists
Explanation:
Developmental psychology is defined as the scientific study that why and how a person change over their entire lifespan. It explains that how the thinking, behavior and feeling of a person changes throughout their life.
Parent have great influence on their child's mindset and there are several instances where parent's thinking determine what their child become in near future. For example, during toddler-hood babies learn to walk and talk and with time development of language take place which is largely determined by the behavior, thinking and feeling of parent.
Answer:
Eelas = 5 [J]
Explanation:
Elastic energy is associated with the ability that has a spring or any other material with elastic properties.
We can calculate the elastic energy by means of the following equation:
where:
k = constant spring = 2.5 [N/m]
x = distance stretched = 2 [m]
