c. 1 bromine atom
<h3>
Explanation:</h3>
What is a compound?
- A compound is a substance that is made up of atoms from different elements.
- The formula of a compound shows the elements making up the compound.
- Additionally, the formula of compound shows the number atoms of each element making up the compound.
In this case;
We are given the Formula KBr
- This is the formula of the compound potassium bromide.
- From the formula, we can tell that the compound is made up of potassium and bromine atoms.
- The formula also shows the number of atoms of each element, that is, 1 potassium atom and 1 bromide atom.
100.4 degree celsius is the temperature of the water having non-electrolyte.
The correct answer is b.
Explanation:
Data given:
mass of non-electrolyte solute = 31.65 grams
volume of water = 220 ml or 0.22 litres
molar mass of solute = 180.18 grams/mole
density of water = 1 gm/mole
Boiling point of water = 100 degrees celsius
molality = ?
Kb for water = 0.51
boiling point elevation or temperature of hot water,T =?
Formula used:
T = mKb equation 1
number of moles of non electrolyte =
number of moles = 0.17 moles
molality =
molality = 0.77 M
putting the values in equation 1
T = 0.77 X 0.51
T = 0.392 degree celsius. is the elevation in temperature when solute is added.
Temperature of the hot water = 100 +0.392
= 100.392 degree celsius.
This is an incomplete Question.
The complete question is:
Carbon disulfide gas and oxygen gas react to form sulfur dioxide gas and carbon dioxide gas. What volume of carbon dioxide would be produced by this reaction if 2.4 m3 of carbon disulfide were consumed? Also, be sure your answer has a unit symbol, and is rounded to 2 significant digits.
Answer:
Explanation:
The balanced chemical reaction will be:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
Given volume=
To calculate the moles, we use the equation:
According to stoichiometry:
1 mole of carbon disulfide gives = 1 mol of carbon dioxide
Thus 107 moles of carbon disulfide gives=
Volume of carbon dioxide =
Thus the volume of carbon dioxide produced by this reaction if of carbon disulfide were consumed.
