Answer:

Electromagnetic force, Strong nuclear force, and Weak nuclear force.

Explanation:
Forces acting

electromagnetic force, strong nuclear force, and weak nuclear force. The electromagnetic force keeps the electrons attached to the atom. The strong nuclear force keeps the protons and neutrons together in the nucleus. The weak nuclear force controls how the atom decays.

<h3>Explanation:</h3>

Step 1: Define

11 g S

Step 2: Identify Conversions

[PT] Molar Mass of S - 32.07 g/mol

Step 3: Convert

Set up: $\displaystyle 11 \ g \ S(\frac{1 \ mol \ S}{32.07 \ g \ S})$
Multiply/Divide: $\displaystyle 0.343 \ mol \ S$

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

0.343 mol S ≈ 0.34 mol S

When 50.0 mL of 1.00 M HCl(aq) and 50.0 mL of 1.00 M NaOH(aq) , both at 22.0 °C, are added to a coffee cup calorimeter, the temp

Igoryamba

Answer:

The heat produced by this reaction is 2887J

Explanation:

The reaction of HCl with NaOH occurs as follows:

HCl + NaOH → H2O + NaCl + ΔH

Where ΔH is released heat due the reaction

The equation of a coffee cup calorimeter is:

Q = C*m*ΔT

Where Q is heat produced,

C is specific heat of the solution (4.18J/g°C),

m is mass of the solution (50mL + 50mL = 100mL = 100g -Because density is 1g/mL)

and ΔT is change in temperature (28.9°C - 22.0°C = 6.9°C)

Replacing:

Q = 4.184J/g°C*100g*6.9°C

Q = 2887J

The heat produced by this reaction is 2887J
