Answer:
According to mass and volume, block density is 2 g/ml
Explanation:
Density is a measure, usually used in physics and chemistry, that relates the mass and volume of a solid or compound.
In general terms, the density is directly proportional to the mass, and inversely proportional to the volume, so increasing the mass will also increase the density.
The formula used to calculate the density is
ρ = 
Therefore, according to the mass and density of the block
ρ = 
= 2g/ml
Being the density of the block equal to 2 g/ml.
<em>The other options are not possible, because the values given do not correspond to the result of the equation.</em>
Answer:
Explanation:
Here, we want to calculate the final volume
We use the general gas equation here:
P1 is the initial pressure which is 0.850 atm
V1 is the initial volume which is 4.25 L
T1 is the initial temperature which is (23 + 273.15 = 296.15 K)
P2 is the final pressure which is 1.50 atm
V2 is the final volume which is unknown
T2 is the final temperature (11.5 + 273.15 = 284.65 K)
Substituting the values, we have:
Answer & Explanation:
- The neutralization of H₂SO₄ with NaOH is occurred according to the balanced equation:
<em>H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O,</em>
It is clear that every 1.0 mol of H₂SO₄ needs 2 mol of NaOH to be neutralized completely.
<em>So, when you mix one mole of sulfuric acid with 1 mole of sodium hydroxide, there will be an excess of sulfuric acid.</em>
<em>Thus, the pH of the solution remain below 7.</em>
