Explain ocean floor spreading and how this process is related to the mid-ocean ridge

Answers

Answer 1

Answer:

Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

Explanation:

Mid-ocean ridges and seafloor spreading can also influence sea levels. As oceanic crust moves away from the shallow mid-ocean ridges, it cools and sinks as it becomes more dense. ... Seafloor spreading proves that the ocean itself is a site of tectonic activity.

i need to do a science project and i have to write about "reducing ocean pollution" could anybody give my ideas? THANKS CHICAS

Answers

Answer:

decomposers

Explanation:

I'm not sure weather your supposed to create an actual experiment or write a paper. If an experiment, test certain acids to see which one can decompose plastics the fastest and determine which one can be spread through the oceans to melt down plastic. If a paper, discuss the idea of genetically modified fish. Some animals in the wild have the ability to eat pollution (wrappers, bottles, ect.), so mutating fish such as bottom feeders to be able to do the same would easily rid the water of pollution and make for one interesting of a paper! hope this sort of helped!

The concentrations of hydrogen ion in two solutions are (a).1×10-4moldm and (b).5×10-9moldm. What is the pH of each solutions?

Answers

Answer:

(a) pH=4.0

(b) pH=8.3

Explanation:

Hello there!

In this case, since the pH is understood as the potential of the hydrogen in an aqueous solution, and we can calculate it is as follows:

[tex]pH=-log([H^+])[/tex]

We simply need to plug in the concentrations on each question as shown below:

(a)

[tex]pH=-log(1x10^{-4})\\\\pH=4[/tex]

What is the value for AG at 300 K if AH = 27 kJ/mol and AS = 0.09 kJ/(mol-K)?

O

A. AG = 54 kJ/mol

O

B. AG=-18 kJ/mol

O

C. AG= 0 kJ/mol

O

D. AG = 27 kJ/mol

Answers

Answer:

0 kJ/mol

Explanation:

Step 1: Given data

Enthalpy change (ΔH): 27 kJ/molEntropy change (ΔS): 0.09 kJ/mol.KAbsolute temperature (T): 300 K

Step 2: Calculate the Gibbs free energy change (ΔG)

We can calculate the Gibbs free energy change using the following expression.

ΔG = ΔH - T × ΔS

ΔG = 27 kJ/mol - 300 K × 0.09 kJ/mol.K = 0 kJ/mol

Since ΔG = 0 kJ/mol, the process in not spontaneous nor non-spontaneous.

Explain what will happen to the organisms that is affected by human activities.

Answers

Answer:

Human activity is by far the biggest cause of habitat loss.

Humans are now responsible for causing changes in the environment that hurt animals and plant species. We take up more space on Earth for our homes and cities. We pollute habitats. ... Human activity often changes or destroys the habitats that plants and animals need to survive.

Explanation:

Human activities are the various actions for recreation, living, or necessity done by people. For instance it includes leisure, entertainment, industry, recreation, war, and exercise.

Over time, destruction of such habitats leads to reduced biodiversity, weakening the Earth's ecosystems, and ultimately posing a major threat to human life. While, significant tracts of habitat have been lost, and along with them many species of plant and animal, steps can be taken to slow and even reverse the process.

One of the most significant ways in which humans have impacted on the lives of other species is by causing climate change. Many animals, including birds and frogs, now breed much earlier in spring in Britain than they did 20 years ago. Whether or not this is having a harmful effect on them has yet to be determined.

Determine the grams of water produced when 250 grams of barium hydroxide react

with 125 grams of HCI. Refer to the balanced equation below.

Ba(OH)2 (aq) + 2HCl (aq) --> 2H2O (l) + BaCl2 (aq) (balanced)

Answers

Answer:

Explanation:

Ba(OH)₂ (aq) + 2HCl (aq) --> 2H₂O (l) + BaCl₂ (aq)

171 g                    2 x 36.5 g     2 x 18 g

73 g of HCl reacts with 171 g of Ba(OH)₂

125 g HCl reacts with 171 x 125 / 73 g of Ba(OH)₂

= 292.8 g of  of Ba(OH)₂

Ba(OH)₂  available is 250 g , so it is the limiting reagent .

171 g of Ba(OH)₂ forms 36 g of water

250 g of Ba(OH)₂ forms 36 x 250 / 171 g of water

= 52.63 g of water.

How are radar and an approaching siren different? How are they similar?

C. The Doppler effect can be observed only with radar, but both
devices use sound waves.
D. The Doppler effect can be observed only in the approaching siren,
but both devices use radio.

Answers

Answer:

b

Explanation:

Radar uses radio, and the siren uses sound waves, but both exhibit the Doppler effect. Therefore, option (C) is correct.

What is Doppler's effect?

Radar operates by emitting radio waves and measuring the reflected waves to detect objects and determine their velocity. On the other hand, an approaching siren emits sound waves that propagate through the air.

Both radar and an approaching siren exhibit the Doppler effect. The Doppler effect is the change in frequency or pitch of waves (sound or electromagnetic) when the source of the waves and the observer are in relative motion. In the case of radar, the Doppler effect is used to measure the velocity of objects based on the frequency shift of the reflected radio waves. Similarly, the Doppler effect is observed with an approaching siren as the sound waves compress and the frequency appears higher as the source approaches the listener.

Therefore, both radar and an approaching siren differ in the type of waves they use (radio waves vs. sound waves), but they share the characteristic of exhibiting the Doppler effect.

How many liters of hydrogen are obtained from the reaction of 4.00 g sodium with excess water, at STP?

Answers

Answer:

V = 1.95 L.

Explanation:

Hell there!

In this case, according to the following reaction between sodium metal and water:

[tex]2Na+2H_2O\rightarrow 2NaOH+H_2[/tex]

We can realize that the moles of hydrogen can be calculated by using the initial mass of sodium, its atomic mass (23.0 g/mol) and the 2:1 mole ratio of sodium to hydrogen to obtain:

[tex]4.00gNa*\frac{1molNa}{23.0gNa} *\frac{1molH_2}{2molNa}=0.0870molH_2[/tex]

Finally, we calculate the volume of hydrogen by using the ideal gas equation whereas the pressure is 1 atm and the temperature 273.15 K according to the STP conditions:

[tex]PV=nRT\\\\V=\frac{nRT}{P}\\\\V=\frac{0.0870mol*0.08206\frac{atm*L}{mol*K}*273.15 K}{1 atm}\\\\V=1.95L[/tex]

Two samples of hot unknown metals of equal temperatures are dropped in separate containers of water at 30 degrees Celsius. The final temperature of sample A is 33.5 degrees, and the final temperature of sample B is 31.8 degrees. Which metal sample had the highest specific heat?

Answers

Answer:

Sample B has the highest specific heat

Explanation:

Specific heat of a material is defined as the heat necessary to increase in the temperature of 1g of material in 1°C.

The material with the highest specific heat requires more energy to increase its temperature.

In the problem, sample A and B are under the same amount of energy but sample A increases more its temperature. That means sample A has the lowest specific heat and:

Sample B has the highest specific heat

A 125.0-g sample of a metal heated to 100.0 ∘C and placed in a calorimeter that contains 250.0 g of water. The temperature rises from 24.3 ∘C to 27.2 ∘C. What is the specific heat capacity of the metal? Ignore the calorimeter in your analysis. Group of answer choices

Answers

Answer:

0.333J/g°C is the specific heat of the metal

Explanation:

The heat that the metaal gives is equal to the heat that water is absorbing. The equation is:

S(metal)*ΔT(metal)*Mass(metal) = S(H2O)*ΔT(H2O)*Mass(H2O)

Where S is specific heat, ΔT is change in temperature and mass the mass in grams of the metal and water.

Replacing:

S(metal)*(100.0°C-27.2°C)*125.0g = 4.184J/g°C*(27.2°C-24.3°C)*250.0g

S(metal) = 4.184J/g°C*(27.2°C-24.3°C)*250.0g / (100.0°C-27.2°C)*125.0g

S(metal) = 0.333J/g°C is the specific heat of the metal
