4.7e^6 is how I would write it. You simply count in from the right side where the decimal is until you reach the point just before the 4.
Answer:
1.33L of gas
Explanation:
1 mole of Baking soda (NaHCO₃) reacts with acetic acid producing 1 mole of CO₂, water and sodium acetate, thus:
NaHCO₃ + CH₃COOH → NaCH₃COO + H₂O + CO₂
5g of NaHCO₃ (Molar mass: 84g/mol) are:
5g × (1mol / 84g) = 0.0595 moles of NaHCO₃ that produce 0.0595 moles of CO₂ -Moles of gas-.
If 1 mole of gas occupies 22.4L, 0.0595 moles occupy:
0.0595 moles gas × (22.4L / mol) = <em>1.33L of gas</em>
We are asked to solve the temperature do Potassium Nitrate KNO3 and Sodium Chloride NaCl has the same molar solubility. The answer is 44.5 degrees Celsius. As per the definition of solubility temperature, the solubility increases when the temperature increases where molecules are allowed to move faster at a higher temperature.
Answer:
Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells. The membrane also maintains the cell potential.
