Kim Chemist proposes that increasing the proportion of butadiene in her glue formulation will make the glue stickier. Her propos

Sunny_sXe [5.5K]

Answer: option D) hypothesis

Explanation:

Kim proposal is an hypothesis, because it is an assumption that will ONLY be accepted as true (i.e becomes a theory) when butadiene successfully makes the glue stickier in several conducted experiments.

But, at the moment Kim proposal is an hypothesis.

Hydrogen peroxide is a chemical used to clean bacteria out of cuts. It does this by creating germ-eating oxygen in this decompos

weeeeeb [17]

Answer:

Coefficient's are 2, 2, 1

Explanation:

We are given;

Unbalanced equation;

H₂O₂ → H₂O + O₂

We are required to determine the suitable coefficients that would balance the equation.

We need to know that for an equation to obey the law of conservation of mass it has to be balanced.
Balancing involves making sure that the number of atoms of each element are equal on both sides of the equation.

In this case;

To balance the equation we put the coefficients 2, 2, 1 respectively

Therefore;

The balanced equation is;

2H₂O₂ → 2H₂O + O₂

Thus, Suitable coefficients are, 2, 2, 1

Determine if the individual bonds in each compound are polar or nonpolar.

almond37 [142]

Answer:

See explanation

Explanation:

For SCl2

S = 2.8, Cl = 3.16 difference = 0.4 polar

H2S

H = 2.2 S= 2.8 difference = 0.6 polar

CF4

C = 2.55, F= 3.98 difference = 1.43

This compound is nonpolar irrespective of the difference in electronegativity because the molecule is symmetrical

PCl5

P= 2.19, Cl= 3.16 difference = 0.97

This compound is nonpolar irrespective of the difference in electronegativity because the molecule is symmetrical

CH4

C = 2.55 H = 2.2 difference = 0.35 the molecule is nonpolar

CaBr2

Ca= 1 Br= 2.96 difference = 1.96

The compound is not just polar but ionic in nature due to large electronegativity difference between the bonding atoms

SF2

S = 2.8 F= 3.98 difference = 1.18

The molecule is polar

CO2

C= 2.55 O= 3.44 difference = 0.89

This compound is nonpolar irrespective of the difference in electronegativity because the molecule is symmetrical

NH3

N= 3.04 H = 2.2 difference =0.84

The molecule is polar

NaS

Na= 0.93 S = 2.8 difference = 1.87

The compound is not just polar but ionic in nature due to large electronegativity difference between the bonding
