Answer:
element
Explanation:
Elements are pure substances with only one kind of atom
Step 1: Write Imbalance Equation
CH₃CHO + O₂ → CO₂ + H₂O
Step 2: Balance Carbon Atoms:
There are 2 carbon atoms at reactant side and one at product side. So multiply CO₂ with 2 to balance them. i.e.
CH₃CHO + O₂ → 2 CO₂ + H₂O
Step 3: Balance Hydrogen Atoms:
There are 4 hydrogen atoms at reactant side and 2 Hydrogen atoms at product side. So, multiply H₂O by 2 to balance Hydrogen on both sides. i.e.
CH₃CHO + O₂ → 2 CO₂ + 2 H₂O
Step 4: Balance Oxygen Atoms:
There are 3 Oxygen atoms at reactant side and 6 Oxygen atoms at product side. In order to balance them multiply O₂ on reactant side by 2.5 (5/2). i.e
CH₃CHO + 5/2 O₂ → 2 CO₂ + 2 H₂O
Step 6: Eliminate Fraction:
Multiply overall equation by 2 to eliminate fraction. i.e.
2 CH₃CHO + 5 O₂ → 4 CO₂ + 4 H₂O
Answer:
Final volume = V₂ = 8.2L
Explanation:
Given data:
Initial volume = 12.3 L
Initial pressure = 40.0 mmHg
Final volume = ?
Final pressure = 60.0 mmHg
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
40.0 mmHg × 12.3 L = 60.0 mmHg × V₂
V₂ = 40.0 mmHg × 12.3 L / 60.0 mmHg
V₂ = 492 mmHg. L / 60.0 mmHg
V₂ = 8.2L
The specific proteins produced by cell B in response to the foreign substance are antibodies.
<h3>What are antibodies?</h3>
Antibodies are specific proteins produced by the immune cells of the body in response to a foreign substance called antigen which produces the immune response.
Antibodies are released by immune cells such as B cells.
The antibodies bind to antigen and tag them for destruction by phagocytes.
Therefore, cell B will produce antibodies.
