what is acide, Base and salt
Answer:
In acid – base chemistry, salts are ionic compounds that result from the neutralization reaction of an acid and a base. Basic salts contain the conjugate base of a weak acid, so when they dissolve in water, they react with water to yield a solution with pH greater than 7.0.

When you climb to the top of a water slide, you are gaining:
O A. gravitational kinetic energy.
B. chemical potential energy.
c. gravitational potential energy.
D. chemical kinetic energy.
Answer:
C
Explanation:
You climbing the water slide gives you potential energy and your building gravitational eneergy.
When we climb the top of a water slide we are gaining gravitational kinetic energy. That is we are moving through the surface and thus we experience both kinetic energy and gravitational energy.
What is kinetic energy?Kinetic energy of a body is generated by virtue of its motion. Gravitational energy is a form of energy by which the an object attracts other object to its center of mass. Both forms of energy are directly proportional to the mass of the object.
Potential energy is generated by virtue of the position and height of the object. As the height from surface increases, potential energy increases. Potential energy and kinetic energy together called as mechanical energy of an object.
When starts moving our potential energy is converting to kinetic energy. Hence, when we climb the top of a water slide kinetic energy starts to increase. Thus, option A is correct.

The process of wearing down by friction-like sand blasting is called
O exfoliiation
O erosion
O Wind Abrasion
O deposition
Answer:
Erosion
Explanation:
Abrasion is a process of erosion which occurs when material being transported wears away at a surface over time. It is the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials. ... Objects transported in waves breaking on coastlines cause abrasion.

The temperature of the water vapor (H,0) inside a pressure cooker increased from 295 K to 395 K. AS
the sample is heated, the pressure of the water vapor went from 21.0 kPa to
Answer:
P₂ = 28.12 KPa
Explanation:
Given data:
Initial temperature = 295 K
Final temperature= 395 K
Initial pressure = 21.0 KPa
Final pressure = ?
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
21.0 KPa / 295 K = P₂/395 K
P₂ = 21.0 KPa× 395 K / 295 K
P₂ = 8295 KPa. K /295 K
P₂ = 28.12 KPa

Define Triple point of water?
Triple point is that temperature, at which the substance is found in all three states i.e. solid, liquid and gas. Every substance has different triple point, because Triple point is just above the freezing point and each substance has different freezing and boiling point.
_____________________________________WATER:Water has a Melting point or Freezing Point (MP or FP) of [tex]0^0[/tex] C or 273K and Boiling point (BP) [tex]100^{0}[/tex] C or 373 K. Since the triple point is just above the MP or FP thus Triple Point of water is [tex]0.01^{0}[/tex]C or 273.16K.

Explanation:
if a substance has a PH of 9 is it an acid, base or nutral.
Answer:
At nine, it can still count as neutral.
Explanation:
The ph scale goes from 0 (acid) to 14 (alkaline/base). The middle would be seven, which is neutral. Nine has more alkalinity than a true neutral, but I believe it is close enough to the middle to not count as a base.
