Answer:

0.14 J/g°C.

Explanation:

  • To calculate the specific heat capacity of Hg, we use the relation:

<em>The amount of heat absorbed by Hg = Q = m.c.ΔT.</em>

where, m is the mass of Hg (m = 50.0 g).

c is the specific heat capacity of Hg = ??? J/g°C.

ΔT is the temperature difference = (final T - initial T = 110.0°C).

∴ The amount of heat absorbed by Hg = Q = m.c.ΔT = 770.0 J.

∴ 770.0 J = (50.0 g)(c)(110.0°C).

<em>∴ c = Q/m.ΔT =</em> (770.0 J)/((50.0 g)(110.0°C) = <em>0.14 J/g°C.</em>

Answer:

Relation between , molality and temperature is as follows.

                T =

It is also known as depression between freezing point where, i is the Van't Hoff factor.

Let us assume that there is 100% dissociation. Hence, the value of i for these given species will be as follows.

         i for  = 3

          i for glucose = 1

          i for NaCl = 2

Depression in freezing point will have a negative sign. Therefore, d

depression in freezing point for the given species is as follows.

       

                 =

       

                  =

     

                   =

Therefore, we can conclude that given species are arranged according to their freezing point depression with the least depression first as follows.

                    Glucose < NaCl <

Which series of atomic numbers represents the ordering of consecutive elements within the periodic table?
statuscvo [17]

Atomic number is same as the number of protons in the element which is further equal to the number of electrons. As the number of electrons increases in the element, the atomic number of the element also increases.

In periodic table, elements are arranged in the groups, and these groups are columns starting from 1 to 18, elements are arranged in increasing order of atomic number. Elements are placed with difference of one atomic number.

First four elements present in the periodic table is:

He atomic number is one (1).

H atomic number is two (2).

Li atomic number is three (3).

Be atomic number is four (4).

Thus, the series of atomic numbers that represents the ordering of consecutive elements within the periodic table is the last option - 1, 2, 3, 4...

Anna007 [38]

Answer:add acid

Explanation:

Methyl orange is red in acid and yellow in base. When added to distilled water and the colour turns yellow, it means it is in its anion form. The equilibrium can be shifted towards the acid form (HMO) by adding acid. The acid will protonate the indicator shifting the position of equilibrium towards the acid side and the solution turns red.

rosijanka [135]
Answer: A

Explanation:
The buoyancy force only takes affect when an object is placed in water and floats. This occurs because the density of that object is less than the density of water.
Water is the main liquid used for measuring the density of an object.

Hope this helps! Please tell me if I am wrong :3
