Answer:
The correct answer is C.
Explanation:
The reaction speed remains constant in region C. This is because the growth rate decreases, tending to zero. Graphically you can see how the slope of the tangent line approaches the horizontal. The slope of the tangent line represents the rate of reaction speed. It is constant because although the concentration continues to increase, the reaction rate does not vary.
Have a nice day!
Explanation:
Bases have a slippery feel when touched but acids do not have a slippery feel.
- An acid is a substance that interacts with water to produce excess hydroxonium ions, H₃O⁺ in an aqueous solution. Here are some of its properties:
- Their dilute solutions have a sour taste.
- They have a burning effect on the skin and are highly corrosive on metals.
- They have the ability to change the colors of indicators.
- They react with bases to form salt and water only.
Examples of acids are:
Hydrochloric acid HCl
Tetraoxosulphate (VI ) acid H₂SO₄
- A base is a substance that interacts with water to produce excess hydroxide ions, OH⁻ in an aqueous solution.
- They typically have a bitter taste.
- They have a soapy feel
- They are electrolytes
- They also change the color of indicators
Examples are:
Potassium hydroxide KOH
Sodium hydroxide NaOH

<h3>
Answer:</h3>
15.0 meters
<h3>
Explanation:</h3>
- Kilometers are units used to measure length.
- Length is also measured using other units which include meters, centimeters, decimeter, millimeter, etc
- To convert one unit to another we use conversion factors.
In this case to know inter-conversion between units of measuring length, we consider the following;
Kilometer(km)
10
Hectometer(Hm)
10
Decameter(dam)
10
Meter (M)
10
Decimeter (dm)
10
Centimeter (cm)
10
Millimeter (mm)
Therefore, to convert km to meter we use the conversion factor (10×10×10) 1000 m/km.
Thus;
0.0150 km is equivalent to;
= 0.0150 km × 1000 m/Km
= 15.0 meters
Thus, 0.0150 km is equivalent to 15.0 meters.
