Answer:
A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. You can think of the compound as being 100% split up into metal ions and hydroxide ions in solution.
Explanation:
<span>ammonium sulphate give 2 moles of ammonium ions
so conc. of ammonium ions =2*0.100=0.200 </span>
<span>The number of atoms in 4.75 moles of gold (Au) is found using Avogadro's number, which is 6.022Ă—1023 mol-1. Determine the number of atoms by multiplying 4.75 moles by Avogadro's number. The number of atoms in 4.75 moles of gold is 2.8605172125000205e24.</span>
Answer:
3.974 x 10¹³ mg
Explanation:
To find the amount in milligrams (mg), you need to multiply the given number by the conversion, 1,000 mg/g. This conversions exists as a ratio which compares the amount of mg per every 1 g. It is important to arrange the ratio in a way that allows for the cancellation of units (grams should be in the denominator).
1,000 mg = 1 g
3.974 x 10¹⁰ g 1,000 mg
----------------------- x ------------------- = 3.974 x 10¹³ mg
1 g
The statement about "Carbon can bond with other carbon atoms to produce cyclic hydrocarbon structures" is true. <span>Carbon
can also bond with other four atoms because of its outer shell (valence shell)
that has four electrons. This is the reason why organic molecules can be so
large because of this bonding. </span>
