Answer: The correct answer is Option b.

Explanation:

From the given options:

Option a: Neap tides

Neap tides occurs when Sun and Moon form right angles with Earth. The total gravitational pull is weakened because it acts from two different directions. These tides occur twice a month. These tides have lower high tides and higher low tides.

Option b: Semidiurnal tides

These tides occur when two highs and two lows are of the same height. This pattern is known as semi-daily or semidiurnal tide. They show the same pattern throughout the day.

Option d: Spring tides

Spring tides happens when Sun, Moon and Earth, all align in the same line. The gravitational pull of Sun and Moon, both contribute to the occurrence of these tides. Hence, these tides have higher high tides and lower low tides.

From the above information, the correct answer is Option b.

How many grams of nano3 remain in solution at 20 ∘c?

Amanda [17]

the table say that at 20 degree celcius 88.0g of NANO3 will remain dissolved in 100 gm of H2O so at 20 degree celcius 80.0g of H20 will dissolve (88.0g)x(80g/100g)=70.4g of NANO3 so at 20 degree celcius 86.3g-70.4g= 15.9 gram of NANO3 will come out of solution.

11.9 g Cl2 is reacted with 10.7 g NaOH. How many moles of NaCl are produced?

melisa1 [442]

Answer:

1. 7.256g of NaCl

2. 47.33g of Cl2

Explanation:

2 moles of Na reacts to produce 2 moles of NaCl

8 moles of Na will still produce 8 moles of NaCl

Mass of NaCl = molar mass of Nacl/moles of Nacl

=58.5/8

=7.256g of NaCl

From the equation, 2 moles of Na reacts with 1 mole of Cl2

3/2 moles of Cl2 will react with 3 moles of Na

Mass of Cl2 = 71/1.5

=47.33g of Cl2

Vinegar is a solution of acetic acid (the solute) in water (the solvent) with a solution density of 1010 g/L. If vinegar is 0.80

Damm [24]

Answer:

4.8 %

Explanation:

We are asked the concentration in % by mass, given the molarity of the solution and its density.

0.8 molar solution means that we have 0.80 moles of acetic acid in 1 liter of solution. If we convert the moles of acetic acid to grams, and the 1 liter solution to grams, since we are given the density of solution, we will have the values necessary to calculate the % by mass:

MW acetic acid = 60.0 g/mol

mass acetic acid (the solute) = 0.80 mol x 60 g / mol = 48.00 g

mass of solution = 1000 cm³ x 1.010 g/ cm³ (1l= 1000 cm³)

= 1010 g

% (by mass) = 48.00 g/ 1010 g x 100 = 4.8 %
