The correct answer is C
This is because acceleration is change in velocity over change in time
Velocity is speed and direction, because they spin in a circle their direction changes. Therefore do does the acceleration
Answer: The correct answer would be : True
I hope that this helps you !
Answer:
Explanation: Ammonia is made out of one nitrogen and three hydrogen atoms. Its structure is tetrahedral. Ammonia is used in nitric acid production, as a fertilizer, and a cleaning solution.
NH3, normally found as a gas, it is caustic and harmful in longterm exposure. NH3 has a boiling point of -33 Celsius, and must be stored under pressure, or at low temperatures.
Ammonia is regulated in the United States as a substance that is a non-flamable gas. However, it still meets the definition of a material that is toxic by inhalation and requires a hazardous safety permit.
Ammonia is usually a gas with a pungent odor. Ammonia used commercially is usually named anhydrous ammonia. An exposure to a very high concentration of ammonia could result in lung damage and death
Ammonia is a gas with a strong smell. Its chemical formula is NH3. If exposed to a very high concentration of ammonia, it can cause lung damage and death.
Ammonia, NH3, is a compound that is has a strong smell. Even though the gas helps the nutrition of our planet, it can cause serious problems to our health.
Ammonia, NH3, is a pungent gas. It is colorless, and used to manufacture fertilizers and
Answer:
In order to prepare 200.0 mL of an aqueous solution of iron (III) chloride, at a concentration of 1.25 x 10⁻² M, you need to weight 0.4055 g of FeCl₃ and add to 200.0 mL of water.
Explanation:
Concentration: 1.25 x 10⁻² M
1,25 x 10⁻² mol FeCl₃ ___ 1000 mL
x ___ 200.0 mL
x = 2.5 x 10⁻³ mol FeCl₃
Mass of FeCl₃:
1 mol FeCl₃ _____________ 162.2 g
2.5 x 10⁻³ mol FeCl₃ _______ y
y = 0.4055 g FeCl₃
The volume of water can be measured by different scale from a micro level to macro. The micro level water can be calculated by micro liter, where as the high quantity of liquid is expressed by gallon. To determine the volume of the water, which is small in grade one should use the milliliter(mL) unit. 1 mL is equivalent to 0.001 liter. The unit in which we are expressing the volume of any liquid should be simple and hand-able data. The volume of the water containing in a cup may be of 50-100 mL. Thus for this much volume using of macro or any other major unit will make the data complicated.
