Solubility at 100 °C = 480 g / 100 mL of solution =: saturated solution
The proportion 240 g / 50 mL is equal to the saturated ratio 480 g / 100 mL
Then, 240 g of sugar in 50 mL of boiling water will make a saturated solution.
Answer: saturated
<u><em>Answer:</em></u>
- Correct option is D. Family 18
<u><em>Explanation.</em></u>
The elements of group 18 of periodic table are called as noble gases. They are stable because they have complete valence shell electrons. So there octet rule is satisfied.
The elements of noble gases are
Answer:
None of the options are correct.
The correct answer is 1.10g
Explanation:
First, we'll begin by balancing the equation given above. This is illustrated below:
2HCl + 2Na —> 2NaCl + H2
Next, let us calculate the mass of HCl that reacted and the mass of H2 produced from the balanced equation. This is illustrated below:
Molar Mass of HCl = 1 + 35.5 = 36.5g/mol
Mass of HCl from the balanced equation = 2 x 36.5 = 73g
Molar Mass of H2 = 2x1 = 2g/mol
Now we can easily find the mass of H2 produced when 40g of HCl reacted as shown below:
From the balanced equation,
73g of HCl produced 2g of H2.
Therefore, 40g of HCl will produce = (40 x 2)/73 = 1.10g of H2.
From the calculations made above,
40g of HCl produced 1.10g of H2
The iron will retain its magnetic properties it will still magnetic and sulfur will not gain the magnetic properties so t will not be magnetic
The Periodic Law
Dmitri Mendeleev developed own periodic law with atomic number as the basis for the arrangement. The Periodic Law, also known as "Mendeleev's Law" states, " When elements are arranged in order of increasing atomic mass, certain sets of properties recur periodically." It also describes the properties of the elements as periodic functions of their atomic weights.
