Answer:
1,300,000,000,000
Explanation:
1.3 x 10^12
We want to convert this from scientific notation.
Tip: in scientific notation the exponent tells you how many place you move the decimal point over. If the exponent is negative you move the decimal point to the left. Ex. For, 4.1 x 10^-8, we would move the decimal point over 8 times to the left to get .00000041. When the exponent is positive we move over to the right. Ex. For, 7.6 x 10^7 we would move the decimal point over 7 times to the right to get 76,000,000
So to convert 1.3 x 10^12 we simply move over the decimal point over 12 times to the right.
1.3 x 10^12 ------> 1,300,000,000,000
Our answer is 1,300,000,000,000
Answer: The ionization of pure water forms <u><em>hydroxide and hydronium ions.</em></u>
Explanation:
Ionization is a reaction in the pure water in which water breaks down into its constituting ions that hydronium ion and hydroxide ions.
One molecule of water looses its proton to form hydroxide ion and l=the lost protons get associated with another water molecule to form hydronium ion.
1/2 L of swamp water (or tap water with mud or dirt added)
2 L soda pop bottle with its lid
2 L plastic soda pop bottle—cut in half (have an adult help with cutting)
1000 ml beaker
2 20 oz cups
1 tbsp alum (aluminum potassium sulfate)
2 c fine sand
1 c coarse sand
1 c small pebbles
1 filter paper or coffee filter
1 rubber band
1 large spoon for stirring
spoon for scooping the alum
stopwatch or timer
Answer:
They don't have values there because they aren't on the pauling scale of electronegativity, as they don't form any compounds with other elements.
Explanation:
Hydrogen only has 1 electron so not A.
Barium has 2 valence electrons so answers B!
