Nitrogen - 15
Sulphur - 16
Explanation:
The question above is related to the "Periodic Table of Elements" which shows the proper arrangement of elements in a table. Every element falls on a<em> group/family</em> within the table. Each group has its own number, and the table has a total of<u> 18 groups</u><em> (from left to right). </em>They are classified according to <em>similarities in their characteristics</em>. For example, group 1 is composed of <em>alkali metals</em> while group 2 is composed of<em> alkali earth metals</em>.
Answer:
The answer is C. 48 grams
Explanation: If the mass of all the ingredients is 48 grams the that would be your in total answer
Answer:
Percent by mass is calculated by tihis formula, Mass of solute (g) ÷ mass of solution (g)] × 100.
Explanation:
For example: if you have a solution 45% m/m (mass percentege), you have 45 g of solute in 100 g of solution.
Answer:
Radius of the bubble reaches the surface of the water = 4.68 cm
Explanation:
We know Ideal gas equation PV = nRT
Since amount of gas and temperature remains constant
so p₁v₁ = p₂v₂
Volume of Spherical bubble with a radius of 3.0 cm
⇒ v₁= 
⇒ v₁ = x 3.14 x 
Pressure at the depth p₁ = 4 atm
Volume of bubble when it reaches the surface of water =
Pressure p₂ = 1 atm
p₁v₁ = p₂v₂
⇒ 4 x x 3.14 x = 1 x
⇒ r = 4.68 cm
