Answer:
it is because a number of factors, including sample surface cleanliness and temperature, can prevent chunks of alkali metals from exploding on contact with water. The team eliminated those variables and others by using a sodium-potassium alloy that remains liquid at room temperature and a droplet delivery system featuring a calibrated syringe.

Answer:
She should use 0.75 mol.
Explanation:
By definition, molarity (M) is the <u>number of moles of solute per liter of solution</u>. One liter of solution is equal to 1000 mL.
Therefore,
1000 mL -------- 1.5 moles of NaCl
500 mL --------- x= 0.75 moles of NaCl
The moles contained in 500 mL of a 1.5 M NaCl solution are 0.75.
Answer:
C(i) the elements are lead (Pb), nitrogen (N) oxygen (O). Lead is found as the Pb 2+ ion and nitrogen and oxygen form the nitrate ion NO 3 –. Its chemical formula is Pb (NO 3) 2.
C(ii) is +2 because the oxidation state of lead is +2. More Lead (II) trioxonitrate(v) is composed of lead ion and the nitrate ion.
