A) Polar (Cl is more electronegative than Si)
b) Nonpolar (Both atoms have the same electronegativity)
c) Ionic (Ionic bonds happen between a metal and a nonmetal)
d) Nonpolar (Hydrogen and carbon have about the same electronegativity) this is a common nonpolar bond)
You can identify the type of bon by looking at what is being bonded (nonmetal or metal) and the placement of the elements on the periodic table (electronegativity increases going up a group and going from left-right across a period).
Answer:
Increasing the temperature
Explanation:
According to Le Chatelier's principle, "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
Since the forward reaction is exothermic, this suggests that heat is given off in the reaction.
Increasing the temperature will favors the reverse process which is endothermic.
In going from the reactants to the the products, the reaction is deemed exothermic which suggests that it produces heat.
The backward reaction is endothermic i.e it absorbs heat. If the temperature is increased, this process will be favored and more reactants produced. Less of the diiodine pentoxide will form. There is a leftward shift of the equilibrium
A) Magnets can attract through solid materials.

Television cause it has a satellite
By definition, the molar mass for the compound strontium nitrate Sr(NO₃)₂ is 211.62 g/mole.
<h3>Definitio of molar mass</h3>
The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.
The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.
<h3>Molar mass of strontium nirate</h3>
In this case, you know the molar mass of the elements is:
- Sr= 87.62 g/mole
- N= 14 g/mole
- O= 16 g/mole
So, the molar mass of the compound Sr(NO₃)₂ is calculated as:
Sr(NO₃)₂= 87.62 g/mole + 2× (14 g/mole + 3×16 g/mole)
Solving:
Sr(NO₃)₂= 211.62 g/mole
Finally, the molar mass for the compound strontium nitrate Sr(NO₃)₂ is 211.62 g/mole.
