Answer:
0 587 mL
Explanation:
First we convert 180 grams of HCl into moles, using its molar mass:
- 180 g ÷ 36.46 g/mol = 4.94 mol HCl
Now we can <u>use the number of moles and the given concentration to calculate the required volume</u>, applying the <em>definition of molarity</em>:
- Molarity = moles / liters
- Liters = Moles / molarity
- 4.94 mol / 8.40 M = 0.588 L
Finally we <u>convert liters into milliliters</u>:
The closest answer is option C, 587 mL.
Answer:
Density (ρ) = 6820 kilogram/cubic meter
Explanation:
ρ = m/v
10.23 gram
1.5 milliliter
= 6.82 gram/milliliter
= 6820 kilogram/cubic meter
Answer:
29.0 g
Explanation:
We know that we will need a chemical equation with masses and molar masses, so let’s start by gathering all the information in one place.
: 63.55 46.01
Cu + 4HNO₃ ⟶ Cu(NO₃)₂ + 2NO₂ + 2H₂O
Mass/g: 20.0
1. Use the molar mass of Cu to calculate the moles of Cu.
2. Use the molar ratio of NO₂:Cu to calculate the moles of NO₂.
3. Use the molar mass of NO₂ to calculate the mass of NO2.
Answer:
i think is probably A
Explanation:
because at constant temperature, the product of the pressure and volume of a given mass of and ideal gass in a closed system is always constant
Correct Answer: Option B i.e. 235 92U + 1 0n→ 140 55Cs + 94 37Rb + 2 (1 0n)
Reason:
Nuclear fission<span> is either a nuclear </span>reaction<span> or a radioactive decay process in which the nucleus of a heavy atom splits into smaller atoms. During this process, large amount of heat is given out.
</span>
This condition of nuclear fission reaction is satisfied only by option B.
Rest all the available options are example of nuclear transmutation reactions.
