<span>In the flavored water homogeneous mixture, water is the solvent and the drink mix is the solute.</span>
Answer: Option (b) is the correct answer.
Explanation:
It is known that in a gas, molecules are away from each other due to more kinetic energy between its particles. As a result, there are more number of collisions between them.
So, when we apply pressure on a gas then its molecules come closer to each other. Due to which there occurs decrease in its volume.
Thus, we can conclude that to investigate the compressibility of a gas increase the pressure on it.
Answer:
C: solvent
Explanation:
When solvent dissolve the solute it form solution. Solvent is present in large quantity while solute is present in less amount. Solution is homogeneous mixture of solvent and solute.
The rule which is followed is "like dissolve like". Polar solvent always dissolve polar solute while non polar solvent dissolve non polar substances.
Let consider the example of water and sodium chloride.
Water is polar substance it consist of H⁺ and OH⁻ ions. Sodium chloride is also polar substance it consist of Na⁺ and Cl ⁻ ions. When sodium chloride is added into the water it get dissolved because water breaks the bond between sodium and chloride and convert it into positive and negative ions. Na⁺ are surrounded by OH⁻ while Cl⁻ are surrounded by H⁺ and salt get dissolved.
Answer: Gold
Explanation: gold has a density of 19.32 g/cm3 where silver has a density of only 10.49 g/cm3
In order to find the mass (in grams) of an element, you just need to multiply the no. of moles given by the atomic mass of the element, which can be found in a periodic table.
mass of 15.0 moles of N= 15.0 x 14.0 = 210g
mass of 5.0 moles of Zn= 5.0 x 65.4 = 327g
mass of 20.0 moles of H= 20.0 x 1.0 = 20g
mass of 1.0 moles of Pb= 1.0 x 207.2 = 207.2g
Therefore, since 327g is the greatest mass out of the 4 options, the answer is 5.0 moles of Zn.
