how does temperature affect spontaneity?
a. if triangleH and triangleS have opposite signs, the temperature will determine spontaneity.
b. if the temperature is high enough, any reaction will become spontaneous
c. temperature will affect spontaneity only if triangleH and triangleS are both positive
d. if triangleH and triangleS have the same sign, the temperature will determine spontaneity
PLEASE HELP TYSM!!!
Answers
Answer:
The correct option is d.
d) If ΔH and ΔS have the same sign, the temperature will determine the spontaneity
Explanation:
Consider the table attached at the bottom which shows Spontaneity and the sign of Enthalpy and Entropy terms.
We can clearly see from the table how temperature effects the Spontaneity.
If the signs of ΔH and ΔS are opposite, the spontaneity doesn't depend on the temperature.
If the signs of ΔH and ΔS are same, then the temperature effects the Spontaneity. If both have negative signs, reaction is spontaneous at low temperature. If both have positive signs, reaction is spontaneous at high temperature.

Answer:
The fact that hot air rises and cold air sinks.... Because Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.
Answer:
It is the first option
Why?
Because hot air rises and cold air rushes to land which causes wind. This type of wind is called land breeze. The thing is that lower the pressure, higher the wind speed
This is why you see with a barometer in storms that the air is in low pressure.

Fire stick Managing the environment through farming Aboriginal people routinely burned grass to minimise fuel and promote new growth in order to attract grazing animals for hunting.
Why is farming important?Among the various ways that agriculture has an impact on society are the provision of food, habitat, and employment opportunities; the provision of raw materials for food and other goods; and the development of robust economies through commerce.
Why is farming beneficial to the environment?A large number of species use pasture and crops as both a habitat and a source of food, making up around 50% of the planet's livable land. Sustainable management of agricultural operations has the potential to safeguard watersheds, restore significant habitats, and improve the quality of the soil and water supply.

which phrase describes air pressure O decreases with denser air O decreases as altitude decreases O equals mass divIded by Volume O decreases as a result of fewer air particles pushing down
Answers
Air pressure decreases as altitude decreases. This phenomenon occurs because the atmosphere's density diminishes with increasing height above the Earth's surface and the correct option is option 2
As one ascends to higher altitudes, there are fewer air particles above, leading to a decrease in air density. Consequently, the pressure exerted by the air decreases at higher elevations.
Conversely, at lower altitudes, the air is denser due to the larger number of air particles above, resulting in higher air pressure. This relationship between air pressure and altitude is crucial for understanding weather patterns, climate changes, and the functioning of various natural processes on Earth.
Thus, the ideal selection is option 2.

Answer:1. Saturated zone
2. the water table
3. Aquifer
4. Land subsidence
Explanation:The saturated zone beneath the water
An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it.
Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.
1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

In 2004, an earthquake struck Sumatra in Indonesia along a tectonic plate boundary under the ocean. When the plates shifted, it caused a tsunami wave to spread outwards and hit different coastlines anywhere from 2 to 8 hours after the quake. Unfortunately, the tsunami waves were so powerful that it became known as one of the deadliest natural disasters in history with over 220,000 deaths and $14 Billion in damages.
Which of the following is the NOT a likely reason why the 2004 Sumatra earthquake caused so much damage?
A. Tsunamis occur instantly and are not preceded by any warning signs.
B. Poor earthquake detection systems did not give people warnings to move farther inland.
C. Most of the countries affected by the tsunami were poor and did not have well-established building codes.

Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves.
What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Was there flowing water on Mars ?The geologic process that could have created the channel on Mars is water moving. We can infer from the image that water running across the terrain on Mars created channels similar to those on Earth.
We can claim that the flowing of water creates the channels on Mars because when the water runs for a long period from the same region, it takes the sediments and creates channels.
