Answer:
period 3 and group 3
Explanation:
I'm saying group 3 because that is how I learnt it at school, but if you count it then it's in group 13.
Answer:
Describe what is happening within the system when it is at equilibrium in terms of concentrations, reactions that occur, and reaction rates.
Explanation:
The chemical equilibrium state is the state where the rate of forward reaction becomes equal to the rate of backward reaction.
At this stage the change in concentration of reactants becomes equal to the change in concentration of products.
The reaction will never cease.
That is the reason chemical equilibrium is called dynamic equilibrium.
So, forward and backward reactions will be taking place continuously at equal rates.
Answer: D=8.27 g/cm³
Explanation:
Density is mass/volume. Mass is in grams and volume is in liters. In this case, the problem wants our volume to be in cm³. All we need to do is to make some conversions to convert kg/m³ to g/cm³.
With this equation, the m³ and kg cancel out, and we are left with g/cm³.
D=8.27 g/cm³
The jet stream is one of the key winds that moves air masses at the direction from west to east it moves.
<h3>What are jet streams?</h3>
Jet streams are strong winds which are flow in the form of narrow bands in the upper part of the atmosphere. On the earth these winds are flows near the altitude of the tropopause. These winds carries weather systems and blows toward the colder northern air and due to the rotation of earth, its direction is from west to east.
Hence jet streams move winds from west to east direction.

Answer:
In the criss-cross method, the numerical value of the ion charge of the two atoms are crossed over, which becomes the subscript of the other ion. Using this technique, we will write the chemical formula of the given compounds.
Criss cross the absolute values to give Al2O3. To find the formula for magnesium oxide:- The oxidation number of Mg is +2 and oxygen is -2. Criss cross the absolute values to give Mg2O2In this example there is a common factor of 2 so divide by 2 to give MgO.
