In your bathroom you leave the faucet dripping. If the faucet leaks 30.0 drops/minute, how much water will you waste after 3.00

Verizon [17]

First let's convert the minutes to hours (multiply minutes by 60 to get hours):

30 × 60 = 1,800 drops/hour

Now that you know how much drops there are per hour, you can multiply this answer by 3 to work out how many drops there are in 3 hours:

1,800 × 3 = 5,400 drops

We know that 5 drops is equal to 1 ml, so we can divide 5,400 by 5 to work out the amount of ml:

5,400 ÷ 5 = 1,080 ml

Therefore, your final answer is 1,080 millilitres (ml)

A 250 cm^3 solution containing 1,46 g of sodium chloride is added to an excess of silver nitrate solution. The reaction is given

faust18 [17]

Answer:

The mass of the precipitate that AgCl is 3.5803 g.

Explanation:

a) To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Mass of solute (NaCl) = 1.46 g

Molar mass of sulfuric acid = 58.5 g/mol

Volume of solution = $250 cm^3 =250 mL$

$1 cm^3= 1 ml$

Putting values in above equation, we get:

$\text{Molarity of solution}=\frac{1.46g\times 1000}{58.5g/mol\times 250}\\\\\text{Molarity of solution}=0.09982 M$

0.09982 M is the concentration of the sodium chloride solution.

b) $NaCl (aq)+AgNO_3 (aq)\rightarrow AgCI(s)+NaNO_3(aq)$

Moles of NaCl = $\frac{1.46 g}{58.5 g/mol}=0.02495 mol$

according to reaction 1 mol of NaCl gives 1 mol of AgCl.

Then 0.02495 moles of NaCl will give:

$\frac{1}{1}\times 0.02495 mol=0.02495 mol$ of AgCl

Mass of 0.02495 moles of AgCl:

$0.02495 mol\times 143.5 g/mol=3.5803 g$

The mass of the precipitate that AgCl is 3.5803 g.

State the guideline you can use to predict the formula of:

Cerrena [4.2K]

We can predict formula of ionic compounds by:

Take a look at where the elements are listed on the periodic table.
The amount of electrons that an element would need to gain or lose in order to resemble an atom of a nearby noble gas is one of the similarities that atoms in the same column as one another (group) tend to display.
Alkali metal group I ions have +1 charges.
Alkaline earth metals (group 2 ions) have a +2 charge.
Nonmetal group 6 ions have a charge of -2.
Halides in group 7 have a -1 charge.
The charges of the transition metals cannot be predicted in a straightforward manner.
Check out a table of charges (valences) to see potential values. The +1, +2, and +3 charges are most frequently employed in beginning and general chemistry courses.
Keep in mind that the positive ion is always stated first when writing an ionic compound's formula.

These are the few guidelines we can use to product formula.
