What is a chemical property of oxygen



A.it is a gas at room temperature
B. it reacts to iron to form rust
C.it expands when heated
Dit combines to form O2 molecules

Answers

Answer 1
Answer: oh ok those are the better choices. well a physical reaction means something changed in the property itself. so we can take off B and C. a chemical reaction means the property of the item changed completely and stayed that way. so im going with D.
Answer 2
Answer: The answer is actually B, since rusting is an obvious chemical reaction which cannot be undone. A is just fact, C can be undone by cooling, and D can be undone by splitting the molecules apart. So the answer is B.

Answers

Answer:

The correct answer will be-

1. Sensory neurons

2. Interneurons

3. Motor neurons

Explanation:

The neurons are the building blocks of the nervous system which transmits the signals in the form of electrical impulse.

The neurons can be categorized on the basis of their functions into three types:  

1. Sensory neuron- The neuron which transmits the signals from the sense organs of the body to the central nervous system.

2. Interneurons- The neuron which connects the sensory neuron to the motor neuron by interpreting the signals from the sensory neurons.

3. Motor neuron- the neuron which transmits the signal from the central nervous system to the muscles and causes the movement of the muscles.

Final answer:

Neurons can be classified as sensory, motor, or interneurons based on the direction they carry impulses. Sensory neurons transmit information to the brain, interneurons process it, and motor neurons carry the response to muscles or glands.

Explanation:

There are three types of neurons. Sensory neurons carry information from sense organs to the spinal cord and brain. In the brain, interneurons carry information from the sensory neurons to motor neurons, which cause muscles to contract and move. Sensory neurons carry nerve impulses from sensory receptors in tissues and organs to the central nervous system. Motor neurons transmit impulses from the central nervous system to muscles and glands, prompting action. Interneurons facilitate communication between sensory and motor neurons.

Sensory neurons, for example, would carry the sensation of touching a hot surface to the brain. The brain processes this via interneurons and sends a signal through motor neurons to withdraw the hand quickly. This sequence illustrates how the different types of neurons collaborate to generate a response.

What conclusion can be made based on thetemperatures of soil, sand, water, and air in Section 1 of
the experiment? Did your results support your
hypothesis? Why or why not?

Answers

Answer:

Explanation:

I can conclude that the type of material affects the absorption of sunlight on Earth's surface because different materials absorb heat from sunlight at different rates. The results support my hypothesis because the results show that air absorbs heat faster than any of the materials. Soil absorbs heat faster than sand, which absorbs heat faster than water.

The hypothesis is true because the heat capacity of water is more than the other given substances.

Specific Heat Capacity:

It is the defined as the energy require to increase the temperature of the of 1 kg substance by one degree Celsius.

The specific heat capacity of the water is higher than the dry soil. It means that the it takes more energy to heat the water and water takes more time to cool up.

Therefore, the hypothesis is true because the heat capacity of water is more than the other given substances.
