Why is creativity important in constructing scientific explanations?
poizon [28]

D. Sometimes it is necessary to put forth new theories to explain  experimental results,

Explanation:

Creativity is important to science because sometimes, it is necessary to put forth new theories to explain experimental results.

Theories are explanation of scientific observations.

  • Most scientists are critical and creative thinkers.
  • They must be able to come up with a wide range of possible explanation to explain their findings.
  • The explanations must be scientific in nature and not fall out of the basic tenets of this way of thinking.
  • Therefore, scientists draw from their wealth of deductive reasoning to give explanations into an observed phenomenon.

For carbon monoxide poisoning, the treatment is administration of oxygen at high pressure. This increases the amount of oxyhemog
Mama L [17]
Adding oxygen will cause the equation of 
CO-Hemogoblin + O2= Hemogoblin = Oxyhemogoblin

to the right. This is because the increase in pressure leads to more on the left side, and as such a balance needs to be maintained so the equation shifts to the right.

How much heat does a 100. g sample of copper absorb when its temperature increases by 30.0°C? The specific heat of copper is 0.3
erica [24]

Answer:

\boxed {\boxed {\sf B. \ 1170 \ Joules }}

Explanation:

We are asked to find how much heat a sample of copper absorbs when the temperature is increased.

Since we know the mass, temperature increase, and specific heat capacity, we can use the following formula to calculate heat.

q= mc \Delta T

The mass of the copper sample is 100 grams, the temperature is changed or increased by 30.0 degrees Celsius, and the specific heat of copper is 0.39 Joules per gram degrees Celsius.

  • m= 100 g
  • c= 0.39 J/g °C
  • ΔT= 30.0 °C

Substitute the values into the formula.

q= (100 \ g )(0.39 \ J/g \textdegree C ) (30.0 \textdegree C )

Multiply the first two values. Note that the units of grams cancel.

q= 39 \ J/ \textdegree C (30.0 \textdegree C )

Multiply again, this time the units of degrees Celsius cancel.

q= 1170 \ J

The copper sample absorbs <u>1170 Joules</u> of heat and <u>Choice B </u>is correct.
