Ionic bonds generally have higher melting points due to stronger electrostatic interactions.
Answer:
3.5 mL
Explanation:
Let us represent lauric acid with the symbol LaCOOH and the anion as LaCOO-. The reaction between the anion and H2SO4 is;
LaCOO-(aq) + H2SO4(aq) -----> LaCOOH(aq) + HSO4-(aq)
Number of moles of LaCOO- = 2.75 g/200 g/mol = 0.014 moles
Since the mole ratio of the reaction is 1:1, then the amount of H2SO4 required is also 0.014 moles
Then;
n = CV
n = number of moles
C= concentration
V = volume
V = n/C
V = 0.014 moles/4.0 M
V= 3.5 * 10^-3 L
V = 3.5 mL
Answer:
Explanation:
<u>1) Data:</u>
- T₁ = 25°C = 25 + 273.15 K = 298.15 K
- T₂ = 20°C = 20 + 273.15 K = 293.15 K
<u>2) Formula:</u>
Used combined law of gases:
<u>3) Solution</u>:
Solve the equation for V₂:
Substitute and compuite:
- V₂ = 98.7 KPa × 10.0 L × 293.15 K / (102.7 KPa × 298.15 K)

Answer: A. aldolase
Explanation:
Phosphofructokinase, is an enzyme which is vital in the regulation of fermentation. It is involved in the glycolysis process.
When it experiences a mutation that was being interfered with the substrate binding, we should note that the enzyme that is going to be most immediately impacted in terms of accessing substrate is aldolase.
Cytokinesis is the division of a cell at the end of mitosis, bringing about the separation into 2 daughter cells.
In animals, cytokinesis occurs when a cleavage furrow forms.
In plants, cytokinesis occurs when a cell wall forms in between the daughter cells.
A cleavage furrow is the indentation of the cell's surface.
Hope this helps ;)
