Answer:

Touching a stove and burning your your hand

Explanation:

Conduction is one of the three methods of heat transfer (the others being convection and radiation). Conduction involves the transfer of heat via direct contact with a solid medium. In conduction, heat or thermal energy moves from the hotter region to the colder region.

In this question, an example of conduction is the act of "Touching a stove and burning your your hand". The stove is acting as the solid medium here, with the heat being transferred from the hot object (stove) to the less hot one (hand) via touch (direct contact).

Which is not a difference between a population showing exponential growth and a population showing logistic growth?
EleoNora [17]

Answer;

Mutation rate

-Mutation rate is not a difference between a population showing exponential growth and a population showing logistic growth.

Explanation;

-When the resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve and when the resources are limited, populations exhibit logistic growth.

-The carrying capacity is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. It affects the size of population and thus has an effect on both exponential and logistic growth.

-Food limits and disease limits are also other factors that may determine the population size in a biological ecosystem.

What is the percentage composition for H2O in this compound Al(OH)3.2H2O?
Gelneren [198K]

Answer:

32.73%

Explanation:

To solve this problem, first find the molar mass of Al(OH)₃.2H₂O

 Atomic mass of Al  = 27g/mol

                            O = 16g/mol

                            H  = 1g/mol

Molar mass = 27 + 3(16 + 1) + 2(2(1) + 16)

                    = 27 + 51 + 36

                   = 114g/mol

Percentage composition  = \frac{36}{114} x 100 = 32.73%

Equal volumes of H2 and O2 are placed in a balloon and then ignited. Assuming that the reaction goes to completion, which gas wi
Sonbull [250]

Answer: Oxygen

Explanation:

2H_2+O_2\rightarrow 2H_2O

As seen from the balanced equation:

2 moles of hydrogen combine with 1 mole of oxygen or 1 mole of hydrogen combine with 1/2 mole of oxygen.

According to Avogadro's law, equal volumes of gases contain equal number of molecules and hence equal number of moles.

Thus if x moles of both gases are present, x moles of hydrogen will combine with \frac{x}{2} moles of oxygen and  x-\frac{x}{2}=\frac{x}{2} moles of oxygen will be left used and will be in excess.

Muiltplying 2.5 x 10^10 by 3.5 x 10^-7
andrey2020 [161]

<u>Answer: </u>

The value of \left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right) is 8750

<u>Solution: </u>

\left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right)

\Rightarrow\left(2.5 \times 10^{10} \times 3.5 \times 10^{-7}\right)

\Rightarrow\left(2.5 \times 3.5 \times\left(10^{10} \times 10^{-7}\right)\right)

\Rightarrow(2.5 \times 3.5) \times\left(10^{10+(-7)}\right)

\Rightarrow(2.5 \times 3.5) \times\left(10^{10+(-7)}\right)

\Rightarrow(2.5 \times 3.5) \times 10^{3}

\Rightarrow 8.75 \times 10^{3}

\Rightarrow 8.75 \times 1000=8750
