The bonds S-S, O-H and Ca-Cl are, respectively, a) nonpolar covalent, polar covalent, ionic polar covalent, b)nonpolar covalent,

Brums [2.3K]

Answer:

nonpolar covalent, polar covalent, ionic

Explanation:

From the question ,

S - S Bond -

Both the atom are same , hence , making a non polar bond , because of no difference between the electronegativity of the atom ,

Hence , the S-S Bond is non polar covalent bond .

O-H bond -

The Oxygen atom is more electronegative than the hydrogen atom , so the bond is polar in nature .

And as the bond is formed by sharing ,

Therefore ,

O-H bond is polar covalent bond .

Ca-Cl bond -

Calcium is a metal , whereas , Chlorine is a non - metal , the bond is ionic in nature ,

Hence , Ca-Cl bond is ionic in nature .

1.)What is a chemical reaction?

harina [27]

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change. Photosynthesis is an example from daily life

PLEASE HELP WITH THESE TWO QUESTIONS

adelina 88 [10]

1. Q=112.8 kJ

2. Q=5.01 kJ

<h3>Further explanation</h3>

The heat required for phase change :

melting/freezing :

Q = mLf

Lf=latent heat of fusion

vaporization/condensation

Q = mLv

Lv=latent heat of vaporization

m=50 g=0.05 kg

Lv (water) = 2256 kJ/kg

$\tt Q=0.05\times 2256=112.8~kJ$

m=15 g=0.015 kg

Lf for water = 334 kj/kg

$\tt Q=0.015\times 334=5.01~kJ$

6. What effect does an increase in blood hydrogen ion levels have on the pH of the blood?

Alexandra [31]

Answer: the two parameters change inversely; as hydrogen ion concentration increases, pH falls. due to the logarithmic relationship, a large change in hydrogen ion concentration is actually a small change in pH. For example, doubling the hydrogen ion concentration causes pH to fall by just 0.3.
