Answer:
The process by which an unstable nucleus emits one or more particles or energy in the form of electromagnetic radiation.
Explanation:
Answer:
A) 0.1225 M
B) 100.4 g/mol
Explanation:
Step 1: Write the generic neutralization reaction
HA(aq) + NaOH(aq) ⇒ NaA(aq) + H₂O(l)
Step 2: Calculate the reacting moles of NaOH
17.73 mL of 0.1036 M NaOH react. The reacting moles are:
0.01773 L × 0.1036 mol/L = 1.837 × 10⁻³ mol
Step 3: Calculate the reacting moles of HA
The molar ratio of HA to NaOH is 1:1. The reacting moles of HA are 1/1 × 1.837 × 10⁻³ mol = 1.837 × 10⁻³ mol.
Step 4: Calculate the molar concentration of HA
1.837 × 10⁻³ moles of HA are in a 15.00 mL volume. The molar concentration is:
M = 1.837 × 10⁻³ mol / 0.01500 L = 0.1225 M
Step 5: Calculate the molar mass of HA
1.837 × 10⁻³ moles of HA weigh 0.1845 g. The molar mass of HA is:
0.1845 g / 1.837 × 10⁻³ mol = 100.4 g/mol
Calorimetry-the science or act of measuring changes in state variables of a body for the purpose of deriving heat transfer associated with changes of its due date.
Bond formation is the way in which atoms interact to form compounds.
<h3>What is bond formation?</h3>
Bond formation is the way in which atoms interact to form compounds. The following are the kind of bonds formed by the atoms;
C and AI - ionic bond
N and P - covalent bond
N and O - covalent bond
The bonds in each of the lattices are;
CuO - ionic bond
Hg - metallic bond
P2O5 - covalent bond
P - covalent bond
CaCl2 - ionic bond
The following is a depiction of the processes shown;
Na0 →Na+1 - oxidation
P0→P+5 - oxidation
AI+3 → AI0 - reduction
The balanced reaction equations are;
2H2O + F2 → 2HF + O2
SO2 + 3H2 → H2S + 2H2O
2H2SO4 + C → 2SO2+CO2+2H2O
