I believe the answer would be energy
240 g NaOH
<em>Step 1</em>. Calculate the moles of NaOH
Moles of NaOH = 0.750 L solution × (8 mol NaOH/1 L solution) = 6 mol NaOH
Step 2. Calculate the mass of NaOH
Mass of NaOH = 6 mol NaOH × (40 g NaOH/1 mol NaOH) = 240 g NaOH
Answer:
• The Na atom is formed when the Na+ ion gains an electron.
• A Na+ ion has 10 electrons and a Na atom has 11 electrons.
• A sodium atom has one more electron shell than a sodium ion.
• A Na+ ion is formed when a Na atom loses an electron
Answer:
K.E = 0.5 j
Explanation:
Given data:
Mass of ball = 50 g (50/1000 =0.05 kg)
Speed of ball = 4.5 m/s
K.E of ball = ?
Solution:
Formula:
K.E = 1/2 m.v²
Now we will put the values in formula
K.E = 1/2 (0.05 kg) (4.5 m/s)²
K.E = 1/2 (0.05 kg) 20.25 m²/s²
K.E = 1/2 (1.0 kg. m²/s²)
K.E = 0.5 kg. m²/s²
j = kg. m²/s²
K.E = 0.5 j
