What is the name of Pb(NO3)2? Explain how you determined the bond type and the steps you used to determine the naming convention for the compound. Please be specific :)

Lead(II) nitrate but idk the rest

Explanation:

lead (II) nitrate

Explanation:

This is an ionic bond because it Is a nonmetal-metal bond. The two outside the parentheses on nitrate is there to balance out the charges since its charge is now -2 (before it was -1) and lead is +2. The two is put in parentheses because that is the number used to multiply -1 to create a number that could be the same as lead's (but negative). "nitrate" stays the same, it doesn't change to nitride.

lol sry for the bad explanation but this is what i answered to the question in my assignment

i don t now

when 25.0 ml of 0.700 mol/l naoh was mixed in a calorimeter with 25.0 ml of 0.700 mol/l hcl, both initially at 20.0 °c, the temperature increased to 22.1 °c. the heat capacity of the calorimeter is 279 j/°c.

the equation for the reaction is:

naoh + hcl → nacl + h₂o

moles of hcl = 0.0250 l hcl ×

0.700

mol hcl

1 l hcl = 0.0175 mol hcl

volume of solution = (25.0 + 25.0) ml = 50.0 ml

mass of solution = 50.0 ml soln ×

1.00

ml soln

= 50.0 g soln

δt=t2-t1

= (22.1 – 20.0) °c = 2.1 °c

the heats involved are

heat from neutralization + heat to warm solution + heat to warm calorimeter = 0

q1+q2+q3=0

nδh+mcδt+cδt=0

0.0175 mol ×

δh

+ 50.0 g × 4.184 j·g⁻¹°c⁻¹ × 2.1 °c + 279 j°c⁻¹ × 2.1 °c = 0

0.0175 mol ×

δh

+ 439.32 j + 585.9 j = 0

0.0175 mol ×

δh

= -1025.22 j

δh=1025.22j0.0175 mol= -58 600 j/mol = -58.6 kj/mol
