Answer:
Number of moles of strontium chloride = 0.004 mol
Explanation:
Given data:
Molarity = 0.2 M
Volume = 20 mL
Moles of strontium chloride = ?
Solution;
Formula:
Molarity = number of moles of solute / volume in litter
Now we will convert the volume into litter.
20 mL/1000mL × 1 L
0.02 L
Now we will put the values in formula:
Molarity = number of moles of solute / volume in litter
Number of moles of solute = Molarity × volume in litter
Number of moles of solute = 0.2 mol/L × 0.02 L
Number of moles of solute = 0.004 mol
The additive inverse of 6 is -6.
Answer: D
Explanation: Bacteria thrives in warm and moist environments.
Answer:
yes that is true.Because they are ions.oppositely chared ions attract each other
If element X has 59 protons then element X has 59 electrons.
Side note: as long as an element stays an atom the number of protons and electrons will always have the same value.
