2. They all have 1 valence electron, they form ions with a +1 charge.

3. cation

4. Lithium, Li

5. Francium, Fr

6. Cesium has a melting point of 28.5 C so I’m assuming that’s the correct answer, Francium is radioactive

7. Sodium, Rubidium, Lithium, and Cesium are all soft metals that can be cut with a knife.

8. Oxygen

9. Hydrogen gas

Hi! I'm on the last question of my homework and I'm stuck on it and was wondering if anyone could help me

Semmy [17]

I am not sure but this is what I think

This question uses the formula connecting mass, density and volume
Which is Density= Mass/Volume

Convert the mass in g
92.5 kg = 92,500g

7.87g/ml = 92,500/ Volume
Volume= 92,500/7.87
= 11,753.5 ml

Now since we have to give the answer in liters we can just divide by 1000 and get
11.75 litres

Draw the product formed when the compound shown below undergoes a reaction with hcl in ch2cl2.

Taya2010 [7]

The product formed when HCl and CH2Cl2 react is CH4
H
H-C- H methane structure
H

HCl react with CH2Cl2 to form methane (CH4) and chlorine gas(Cl2)
that is,

2HCl(g) + CH2Cl2(l) = CH4 (g) +2Cl2 (g)
