Rina8888 [55]

Answer:

Temporary hardness is a type of water hardness caused by the presence of dissolved bicarbonate minerals (calcium bicarbonate and magnesium bicarbonate). ... However, unlike the permanent hardness caused by sulfate and chloride compounds, this "temporary" hardness can be reduced by boiling the water.

How many atoms are in 0.75 moles of CH4?
Anastasy [175]

Answer:

Explanation:

Thus, if we have 6.022 × 10 23 O atoms, we say we have 1 mol of O atoms. If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms. Similarly, if we have 0.5 mol of benzene (C 6H 6) molecules, we have 0.5 × (6.022 × 10 23) C 6H 6 molecules, or 3.011 × 10 23 C 6H 6 molecules.

For example the atomic mass of methane (CH4)is 12 amu for the carbon plus 4 x 1 amu for the four hydrogens, for a total of 16 amu. Therefore the molar mass of methane is 16g. We say that one mole of methane has a mass of 16 g, and that there are 6.022 x 1023 atoms in that mass of methane.

How many moles are in 428 L of chlorine gas
djyliett [7]

Answer:

19.3 moles

Explanation:

In order to calculate the number of moles of Chlorine gas from the volume, we have to calculate its mass from its known density using the formula:

Density (g/L) = mass (g) /volume (L)

Density of Chlorine gas= 3.2g/L

Volume = 428L

3.2 = mass/428

mass = 428 × 3.2

mass = 1369.6g

Using mole = mass ÷ molar mass

Molar mass of chlorine (Cl2) = 35.5 × 2

= 71g/mol

mole = 1369.6 ÷ 71

mole = 19.2901

mole = 19.3 moles
