Answer:
1. Na2SO4(aq)+C4H6BaO4(aq) --> BaSO4(s) + 2C2H3NaO2(aq)
2. 2Na^+1(aq) + SO4^-2(aq) + 4C^+4(aq) + 6H^+1(aq) + Ba^-2(aq) + 4O^-2(aq) --> BaSO4(s) + 2C^-4(aq) + 2H^+1(aq) + 3Na^+1(aq) + 2O^-2(aq)
3. Ba^+2(aq) + SO4^-2(aq) --> BaSO4(s)
Explanation:
Answer:
24.2 mL.
Explanation:
<em>Assuming constant temperature</em>, we can solve this problem using <em>Boyle's law</em>, which states:
Where:
We <u>input the data</u>:
- 0.98 bar * 25 mL = 1.013 bar * V₂
And <u>solve for V₂</u>:
The closest option is the second one: 24.2 mL.
Answer:
0.00782 mol Pb
Explanation:
There are always 6.02 × 10²³ atoms in 1 mole of an element.
4.71 × 10²¹ atoms Pb × (1 mol Pb ÷ 6.02 × 10²³ atoms) = 0.00782 mol Pb
Answer:
The measurements of the body resistance to acceleration by some external force is its ,B. inertial mass
