Answer:
Explanation:
Gold (111) Chloride:
AuCl₃
The oxidation state of gold is +3.
Chlorine is present in group seventeen and have seven valance electrons . Thus it accept one electron to complete the octet and show oxidation state -1.
When it react with gold(III) three chlorine atoms are combine with one gold atom to make compound overall neutral.
Calcium Carbonate:
CaCO₃
Carbonate formula is CO₃²⁻ . It means it carry -2 charge . Calcium is present in group two. It has two valance electrons and lose them to get complete octet thus shows +2 oxidation state.
When it combine with carbonate the overall compound is neutral because -2 and +2 charges cancel each other.
Hydrobromic Acid
HBr
Hydrogen has one electron while bromine has seven valance electrons. Bromine require one more electron to complete the octet. It react with hydrogen by sharing of one electron of hydrogen and form polar covalent compound.
Answer:
c
Explanation:
because forces act on an object and make it change direction based upon strength hope this helps.
The answer would be C- both hydrogen and covalent bonds.
Answer:
The calculator add the CO2 released from the use of electricity, released from driving and the CO2 from the waste that we disposed.
Explanation:
The carbon dioxide, CO2 is what the human body does not need, therefore, we breathe it out, hence taking in oxygen(respiration process). The plants need oxygen for the production of their own food.
The carbon calculator estimate the amount of CO2 that each individual releases into the atmosphere through the consideration of several factors such as the kind of food that we eat.
Therefore, if we are to use the carbon calculator to determine the amount of CO2 that each individual releases into the atmosphere we will have:
The amount of CO2 that each individual releases into the atmosphere =( CO2 released from the use of electricity) + (CO2 released from driving) + (the CO2 from the waste that we disposed).
The calculation of pH is based on the activity (aH) of hydrogen ions (H+) dissolved in solution. Specifically, the pH range of numbers is based on a logarithmic scale:
pH=-log (aH)
Log functions are used to rescale very large numbers (or very small numbers) into values much closer to 1. This is often done to deal with more reasonable
Numbers (for pH, 1 to 14). Mathematically, the negative sign in the formula means that pH must be less than 1.
The lower the number on the pH scale, the greater the concentration of hydrogen ions and the greater the material's acidity. The higher the number assigned on the pH scale, the greater the concentration of hydroxide ions and the more basic, or alkaline, the material.
The answer is 4.
