following tests will be most helpful in confirming the identity of the powder?
A
Adding a small amount of vinegar to the powder
B
Dissolving the powder in a beaker of water
C
Testing the electrical conductivity of it in solution
D
Comparing the color of the powder to other powders
Answers
In order to identify whether unknown powder is baking soda or not, adding a small amount of vinegar to the powder would be the best test as it can be observed with the given table that only the baking soda reacts with vinegar. Thus, the correct option is A). Adding a small amount of vinegar to the powder.
What is the way to identity the baking soda?Baking soda is natural chemical that is commonly known as sodium bicarbonate. It is white in color and salt composed of a sodium cation. It often appears as a fine powder.
There are two ways to test whether the baking soda is still active or not. First, drop half teaspoon of baking soda into hot water and observe if it fizzes and forms bubbles, then it's still good. Second way, drop half teaspoon of soda into a small amount of vinegar and if it fizzes, it's still active.
Thus, it can be concluded that the baking soda reacts with the vinegar. So, in order to identify it just add small amount of vinegar to the powder.

Answers
Answer:
Hi. You didn't show the maps, however, I can help by stating that a map showing the distribution of neighborhoods in Singapore would be more likely to be used by a government agency that seeks to promote equal opportunities between ethnic groups.
Explanation:
Singapore is a region with a great cultural diversity and a large number of foreigners, which allows many ethnic groups to come together and form neighborhoods that are distributed in the city. As we know, some ethnic groups are favored which makes the neighborhoods have better infrastructure in relation to the formed neighborhoods and less favored ethnicities.
A map showing these neighborhoods and their distribution in the city could be used for several reasons, however, in relation to the options shown in the question, it would be more likely that a government agency that seeks to promote equal opportunities between ethnic groups would make decisions based on the spatial pattern shown on the maps.
The individuals or organizations that would be most likely to make a decision based on the spatial pattern shown on the maps is a government agency that seeks to promote equal opportunities between ethnic groups.
Because the question does not contain the map that needs to be analyzed, I will help out by giving a general overview and using deductive analysis to help you out.
When a person uses a spatial pattern on a map to make a decision, then that person is trying to differentiate between various groups of people to make the best decision that would benefit them.
As a result of this, the most likely answer would be a government agency that seeks to promote equal opportunities between ethnic groups.

what is the pressure at a depth of 5,000 km
Answers
Answer:
The pressure increases about one atmosphere for every 10 meters of water depth. At a depth of 5,000 meters the pressure will be approximately 500 atmospheres or 500 times greater than the pressure at sea level.
Explanation:
your welcome
For every 10 meters of sea depth, the pressure rises by approximately one atmosphere. The pressure will be about 500 atmospheres, or 500 times more than the pressure at sea level, at a depth of 5,000 meters.
What do you mean by the pressure?The physical force applied to an object is referred to as pressure. Per unit area, a perpendicular force is delivered to the surface of the objects.
F/A is the fundamental formula for pressure (Force per unit area). Pascals are a unit of pressure (Pa). Absolute, atmospheric, differential, and gauge pressures are different types of pressure.
The pressure relative to the surrounding air is referred to as gauge pressure (sometimes spelled gauge pressure). A common mechanical quantity is pressure.
Pressure is frequently expressed as the depth of a particular fluid and is typically measured by its capacity to move a column of liquid in a manometer.
Therefore, for every 10 meters of sea depth, the pressure rises by approximately one atmosphere. The pressure will be about 500 atmospheres, or 500 times more than the pressure at sea level, at a depth of 5,000 meters.

The Pressure at the depth of 500 is supposed to be something related to the air pressure which is also approximately 500km per hour and is also known as the atmospheric pressure.
What is the meaning of atmospheric pressure.?
The terms "atmospheric pressure" and "barometric pressure" describe the pressure that exists within the Earth's atmosphere. 101,325 Pa, which is the same as 1013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi, is the definition of the standard atmosphere.
The heavy air around you presses against everything you touch. The term "air pressure" or "atmospheric pressure" is used to describe this pressure. It refers to the force that the air above a surface applies to it while gravity pulls the surface toward Earth.
