Answer:

Explained below

Explanation:

1) Hydrogen bonds are formed between molecules

All these is because the bonds are flexible in such a manner that in the liquid phase, the molecules are relatively close to each other.

However, it is also noted that the hexagonal arrangement of ice is formed the bonds will be locked in place which will result in the average distance between molecules actually increasing which in turn means given a result that ice is less dense than liquid water.

B) Water possesses a high boiling point: This is because the Hydrogen oxygen bond or O-H bonds are highly polar and the Hydrogen atoms in this bond are located at two corners of the tetrahedron shaped like bond shape which gives water it's high molecular polarity in which in turn makes the molecules to stick together.

How many grams are in 3.00 x 10^24 molecules of Zn(C2H3O2)2?​
Burka [1]

Answer:

Mass = 917.4 g

Explanation:

Given data:

Number of molecules = 3.00 ×10²⁴ molecules

Mass in gram = ?

Solution:

1 mole contain 6.022 × 10²³ molecules

3.00 ×10²⁴ molecules × 1 mol /  6.022 × 10²³ molecules

0.5×10¹ mol

5 mol

Mass in gram:

Mass = number of moles  × molar mass

Mass = 5 mol  × 183.48 g/mol

Mass = 917.4 g

Calculate ΔH° = for the chemical reaction
babymother [125]

Answer: \Delta H^0 for the reaction Cl_2(g)+F_2(g)\rightarrow 2ClF(g)  is -108kJ

Explanation:

The balanced chemical reaction is,

The expression for enthalpy change is,

\Delta H=[n\times B.E_{reactants}]-[n\times B.E{products}]

where, n = number of moles

Now put all the given values in this expression, we get

\Delta H=[1\times B.E_{Cl_2}+1\times B.E_{F_2}]-[2\times B.E_{ClF}]

\Delta H=[(1\times 243)+(1\times 159)]-[2\times 255]

\Delta H=-108kJ

Thus \Delta H^0 for the reaction Cl_2(g)+F_2(g)\rightarrow 2ClF(g)  is -108kJ

5. At what phase of mitosis does the number of chromosomes double?
klasskru [66]
This doesn't happen in mitosis. Mitosis is preceded by interphase. Interphase has three phases: G1, S and G2. What you call chromosome doubling happens in S phase.

When ammonium nitrate is dissolved in water in a glass container, the glass container becomes cold. Is this an endothermic or ex
Trava [24]

Answer:

Explanation:

Figure 6. An instant cold pack consists of a bag containing solid ammonium nitrate and a second bag of water. When the bag of water is broken, the pack becomes cold because the dissolution of ammonium nitrate is an endothermic process that removes thermal energy from the water.
