Answer:u would have 40
Explanation:
because ur taking them away
Your answer is D. You're Welcome
1. 2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂
2. CH₄ + 2O₂ → CO₂ + 2H₂O
3. Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag
4. MnO₂ + 4HCl → MnCl₂ + 2H₂O + Cl₂
5. Pb(NO₃)₂ + 2NaCl → PbCl₂ + 2NaNO₃
1)
![NaCl+AgNO_3=>NaNO_3+AgC\downarrow](https://tex.z-dn.net/?f=NaCl%2BAgNO_3%3D%3ENaNO_3%2BAgC%5Cdownarrow)
2)
CuSO_4+Cu_2Cl_2\neq>

Answer:
<h3>The answer is 1.02 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5C)
From the question
mass of block = 25 g
volume = 24.5 cm³
The density of the block is
![density = \frac{25}{24.5} \\ = 1.020408163...](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B25%7D%7B24.5%7D%20%20%5C%5C%20%20%3D%201.020408163...)
We have the final answer as
<h3>1.02 g/cm³</h3>
Hope this helps you
Answer:
We have the final answer as
<h2>0.68 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5C)
From the question
mass = 40.8 g
volume = 60 mL
The density is
![density = \frac{40.8}{60} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B40.8%7D%7B60%7D%20%20%5C%5C%20%20)
We have the final answer as
<h3>0.68 g/mL</h3>
Hope this helps you
