The Ka is 0.0104.
To solve for the Ka, the formula is Ka = [H+][ClO-]/[HClO].
In order to determine the value of H+, the formula is H+ = 10^-pH (the pH here
is 1.80). This yields 0.015848931924611134. In the ICE table, since H+ is the same
value as ClO, then the ClO is also 0.015848931924611134. The HClO is the 0.04 -
0.015848931924611134. Substituting the values to the earlier mentioned
equation, the answer is 0.01040072606175673227903507631149 or simply, 0.0104.
Answer:
1.45 x 10⁻² g CO₂
Explanation:
To find the mass of carbon dioxide, you need to (1) convert grams CH₄ to moles CH₄ (via molar mass), then (2) convert moles CH₄ to moles CO₂ (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles CO₂ to grams CO₂ (via molar mass). The final answer should have 3 sig figs to reflect the given value (5.30 x 10⁻³ g).
Molar Mass (CH₄): 12.011 g/mol + 4(1.008 g/mol)
Molar Mass (CH₄): 16.043 g/mol
Combustion of Methane:
1 CH₄ + 2 O₂ ---> 2 H₂O + 1 CO₂
Molar Mass (CO₂): 12.011 g/mol + 2(15.998 g/mol)
Molar Mass (CO₂): 44.007 g/mol
5.30 x 10⁻³ g CH₄ 1 mole 1 mole CO₂ 44.007 g
--------------------------- x ---------------- x --------------------- x ----------------- =
16.043 g 1 mole CH₄ 1 mole
= 0.0145 g CO₂
= 1.45 x 10⁻² g CO₂
Answer : The number of electrons shared between 1 nitrogen atom and 1 carbon atom are, Six.
Explanation :
Covalent bond : Covalent bonds are made by the sharing of valence electrons between the non-metal elements.
One covalent bond is formed by the sharing of two electrons.
In the given structure of compound, one nitrogen atom bonded with one carbon atom by three covalent bonds. That means the number of sharing electrons between the one nitrogen atom and one carbon atom are six.

matches with malleable, soft and shiny
These are tyipical properties of alkalyne metals. You can cut sodium with a knife as it is very soft.
Bromine matches with highly reactive gas
Bromine is an halogen and indeed is very reactive
Silicon matches with has
properties of both metals and nonmetals
Silicon is a metaloid so it has some properties of metals and some of nonmetals.
Argon matches with non reactive gas.
Argon is a noble gas, and as such it is not reactive.

Answer:
80 mL
Explanation:
Step 1: Given data
- Initial pressure of hydrogen (P₁): 360 mmHg
- Initial volume of hydrogen (V₁): 240 mL
- Final pressure of hydrogen (P₂): 1080 mmHg
- Final volume of hydrogen (V₂): ?
Step 2: Calculate the final volume of hydrogen
If we assume ideal behavior and constant temperature, we can calculate the final volume occupied by hydrogen using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁/P₂
V₂ = 360 mmHg × 240 mL/1080 mmHg = 80 mL
