In carbon dioxide, how many grams of oxygen would there be if there are 24
grams of carbon?
a 55 g
b 73 g
c 64 g
d 88 g

Answers

Answer 1

Answer:

c. 64 grams

Explanation:

What is the proper combining ratio (by mass) for carbon to oxygen in the reaction that forms carbon dioxide (CO 2)? From the data given in question 1, since 64 grams of oxygen reacts with 24 grams of carbon, the ratio must be 64 to 24, which is 2.7 parts oxygen to 1 part carbon.

During exercise, heart rate can rise dramatically, from a resting rate of 60–80 beats per minute to a maximum rate of about 200 for a young adult. While you are running, blood flow is diverted toward tissues that need it most. For example, muscles in the arteries in your legs relax to allow more blood flow.

Which statement best describes the position of a coastal area during a low
tide?
A. It is on a side of Earth that is perpendicular to the Moon.
B. It is on the part of Earth that is experiencing nighttime.
C. It is on the part of Earth that is experiencing daylight.
D. It is on a side of Earth that faces the Moon directly.

Answers

Answer:

A is the correct answer

Explanation:

Moon pulls the ocean upwards causing tides

The position of a coastal area during a low tide is: it is on a side of Earth that is perpendicular to the Moon.

What happens during low tide?

Whenever the absolute bottom, or the box, arrives at a coast, the coast encounters a low tide. Envision the sea is molded like a ball pointing at the moon. The football's sharp closures address the pieces of the Earth encountering elevated tide and the ball's level sides are the pieces of the earth encountering low tide.

Thus, option A is correct.

It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.

These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang. Heavier atoms such as carbon, oxygen and iron, have since been continuously produced in the hearts of stars and catapulted throughout the universe in spectacular stellar explosions called supernovae.

Many plants in rainforests have leaf tips that come to a point, so precipitation drains off the leaf. This helps to keep the plant safe from harmful germs. Based on this info, what resource is prevalent in a rainforest?

Answers

Answer:

rainfall/water

Explanation:

The possession of drip tips by the leaves of plants in the rainforest is a form of adaptation against high rainfall. Without the drip tips on leaves, water will persist on the surface of leaves, and in conjunction with the warm climate, promotes the growth of pathogens such as fungi and bacteria.

Hence, the possession of drip tips on leaves is an indication of the prevalence of water in the rainforest region.

B) Generating electricity from a coal-fired power plant
C) Generating electricity from a nuclear power plant
D) Generating electricity from a solar panel system

Answers

Hello!

The answer to this question is: D) Generating electricity from a solar panel system.

Thank you for asking this question!

It would be greatly appreciated if you thanked me and marked me as the brainliest!

Have an amazing day.

The energy transformation which produces electricity and is least likely to

negatively impact the environment is generating electricity from a solar

panel system.

Generating electricity from solar panel involves the use of solar energy from

the sun to generate electricity . This type of energy doesn't emit any type of

harmful radiation or release toxic compounds into the atmosphere which

makes it the least likely to negatively impact the environment.

Other options emit any type of harmful radiation or release toxic compounds

into the atmosphere which makes option D the most appropriate.

The maximum allowable concentration of Pb2+ ions in water in a local community is 1.51 x 10-8 M. Could a chemist use 2.00 mL of 0.12 M KBr solution on a 5.00 mL sample of tap water to prove through a precipitation reaction that the water supply is safe? Show all work and reasoning

Answers

Answer:

The water supply is not safe.

Explanation:

Ionically, the reaction is;

Pb^2+(aq) + 2Br^-(aq) -------> PbBr2(s)

Amount of Br^- reacted = 2/1000 * 0.12 = 2.4 * 10^-4 moles

From the reaction equation;

1 mole of Pb^2+ requires 2 moles of Br^- for complete precipitation

x moles of Pb^2+ requires 2.4 * 10^-4 moles of Br^-

x = 1 * 2.4 * 10^-4 /2

x = 1.2 * 10^-4 moles of Pb^2+

Concentration of Pb^2+ precipitated from 5ml of tap water =  1.2 * 10^-4 * 1000/5

Concentration = 2.4 * 10^-2 M

The amount of  Pb^2+ found in the water is greater than the maximum allowable concentration of Pb2+ ions in water in a local community which is 1.51 x 10-8 M. Therefore, the water supply is not safe.

The elements mercury and bromine are both liquids at room temperature, but mercury is considered a metal, and bromine is considered a non-metal. How can that be? Explain using properties you know of.

Answers

Answer:

At room temperature, mercury and bromine are of fluid consistency, it is because their melting or melting temperature is very low, so low that it reaches room temperature.

Compared to mercury and other metals, the more traditional metals have much higher melting temperatures.

On the other hand, bromine is not a metal, since it does not have the ability to oxidize with the presence of oxygen and also does not give up electrons.

Mercury in the periodic table is Hg, and bromine is Br

Combine the following ions to create neutral compounds Y3+ and OH-

Answers

Answer:

Y(OH)₃

Explanation:

Given ions:

                  Y³⁺      OH⁻

To find a neutral compound that conforms with the formation of the given ions;

We us the exchange of valency approach to solve this problem. The valency will form the combining power of the ions for the combination.

                                    Y³⁺      OH⁻

Combining power        3           1

Exchange of valency    1            3

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.There are different types of ecosystems present.
