Answer:
![\boxed{\sf Density = 3.12 \ kg/L}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%5Csf%20Density%20%3D%203.12%20%5C%20kg%2FL%7D%20)
Given:
Mass = 2.56 kg
Volume = 0.820 L
To Find:
Density
Explanation:
Formula:
![\boxed{ \bold{Density = \frac{Mass}{Volume}}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cbold%7BDensity%20%3D%20%5Cfrac%7BMass%7D%7BVolume%7D%7D%7D)
Substituting value of mass & volume in the formula:
![\sf \implies Density = \frac{2.56}{0.820} \\ \\ \sf \implies Density = 3.12 \: kg/L](https://tex.z-dn.net/?f=%20%5Csf%20%5Cimplies%20Density%20%3D%20%20%5Cfrac%7B2.56%7D%7B0.820%7D%20%5C%5C%20%20%5C%5C%20%20%20%5Csf%20%5Cimplies%20Density%20%3D%20%203.12%20%5C%3A%20kg%2FL%20)

Answer: A physical change is a change that can be undone.
Explanation: An example of this is mixing red blocks, green blocks, and blue blocks. You can easily separate them.
Answer:
Acid salts are the converse of basic salts; they are formed in the neutralization reaction between a strong acid and a weak base. ... For instance, in the reaction of hydrochloric acid (a strong acid) with ammonia (a weak base), water is formed, along with ammonium chloride.
Answer:
2.938 mol Pb(NO₃)₄
Explanation:
Step 1: Given data
- Moles of NH₄NO₃ to be produced: 11.75 mol
Step 2: Write the balanced equation
4 (NH₄)₃PO₄ + 3 Pb(NO₃)₄ = Pb₃(PO₄)₄ + 12 NH₄NO₃
Step 3: Calculate the number of moles of Pb(NO₃)₄required to produce 11.75 moles of NH₄NO₃
The molar ratio of Pb(NO₃)₄ to NH₄NO₃ is 3:12.
11.75 mol NH₄NO₃ × (3 mol Pb(NO₃)₄/12 mol NH₄NO₃) = 2.938 mol Pb(NO₃)₄
