<span>The two categories for classifying particulate matter are through analysis of the intensive and extensive properties. Intensive properties are independent properties that can be measured independent of the amount of matter while extensive properties are measured dependent on the amount.</span>
Nitrogen, arsenic, antimony & bismuth
Explanation:
Phosphorus belongs to the 15th group, that is nitrogen family.
Natures are decided by the number of valence electrons.
In a family, all elements have same outer electronic configuration or you say number of electrons.
General electronic con.: ns²np³
Answer:
Think of each polar bond in a molecule as a little arrow pointing from positive to negative. This tells us that the bond dipole is a vector quantity. Like any other vector quantity, the direction is a vital aspect of its description. So, the geometry of the molecule determines the direction that the bond dipole vectors point. The polarity of the molecule results from adding up all these individual bond dipoles.

You answer would be B the second one
Answer:
The maximum concentration of HCl that can be used is 7.08 M
Explanation:
The reaction that takes place is:
- 2HCl(aq) + Mg → MgCl₂ + H₂
The <u>available moles of Mg are</u>:
- 9.00 g Mg ÷ 24.3 g/mol = 0.370 mol
H₂ gas is produced and fills the balloon. We use PV=nRT <u>to calculate the maximum moles of H₂ that can be produced before the balloon pops off:</u>
- 1.00 atm * 6.00 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 318.16 K
Now that we know that we have more than enough moles of Mg to produce 0.230 moles of H₂, we know that HCl is the limiting reactant.
We calculate the<u> required moles of HCl</u>:
- 0.230 mol H₂ *
= 0.460 mol HCl
Now we use C = n/V to <u>calculate the concentration of HCl</u>:
- C = 0.460 mol HCl / 0.065 L = 7.08 M
