M is the unit for concentration (C)
The units for concentration is mol/ L
To find moles you would have to multiply concentration x volume to cancel out the volume and find get moles (n)
For ex:
Moles (n) = C x V (concentration x volume)
N = 1.23 mol/L x 5L (vol. gets cancelled out)
N = 6.15 moles (you get left with moles)
OR to find concentration:
C = 6.15 moles / 5L
C = 1.23 mols/L OR 1.23 M
Explanation: When an object moves from its initial position, it acquires some energy. This energy is called kinetic energy, as it is governed by the motion of an object. ... Thus, it is concluded that kinetic energy is the energy an object has due to its motion.
Answer:
Cu₃(PO₄)₂(s), RbNO₃(aq)
Explanation:
This reaction looks like a possible <em>double replacement reaction</em>, in which the metal ions have exchanged partners.
3Cu(NO₃)₂(aq) + 2Rb₃PO₄(aq) ⟶ Cu₃(PO₄)₂ + 6RbNO₃
You must recall the pertinent <em>solubility rules</em>:
1. Salts of Group 1 elements (e.g., Rb⁺) are soluble.
2. Salts containing nitrate ions (NO₃⁻) are soluble.
3. Most salts containing phosphate ions (PO₄³⁻) are insoluble
According to Rules 1 and 1, RbNO₃ is soluble.
According to Rule 3, Cu₃(PO₄)₂ is insoluble.
∴ 3Cu(NO₃)₂(aq) + 2Rb₃PO₄(aq) ⟶ Cu₃(PO₄)₂(s) + 6RbNO₃(aq)
Answer: Directly through the phospholipid membrane
Explanation:
The cell membrane consist of a phospholipid bilayers structure. In the interior of the membrane, the phospholipid tail are hydrophobic, which makes the cell membrane to be selectively permeable, it is permeable to non polar molecules and impermeable to polar molecules.
Because Steroids are fat soluble, non polar compounds, they can diffuse directly through the hydrophobic, non polar core of the phospholipid bilayer without the use of carrier proteins.
Answer: Compound are different than elements because compounds are combinations of 2 or more elements.
