Graphite is used
hope this helps
The formula of determining the molarity is:
molarity = -(1)
Volume of solution = (given)
Since, 1 mL = 0.001 L
Therefore, volume of the solution = 0.22 L
Molarity = 0.194 M (given)
Substituting the values in formula (1)
Now, number of moles = -(2)
Molar mass of =
Substituting the value of number of moles and molar mass of in equation -(2)
Hence, the mass in grams of potassium permanganate the chemist has added to the flask is .
Answer:
strong base
Explanation:
because a element having pH of greater than 7 is a base and the color of the substance is purple
so it is a strong base
Answer:
How do we know what the temperature of the Earth was in the past? - One way to measure past temperatures is to study ice cores. Whenever snow falls, small bubbles filled with atmospheric gases get trapped within it. In some places, so much snow falls that the older layers become buried and compressed into ice, locking away air bubbles in ice sheets and glaciers
What is the relationship between CO2 (carbon dioxide) and temperature on Earth? - When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.
What is the greenhouse effect? - the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Why are global sea levels rising? - Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms.
