What Is The Symbol Of Atomic Number 47? (2024)

To expect molecular shape, we normally use a principle known as the valence shell electron pair (VSEPR) repulsion principle.

The VSEPR is based on the concept that valence electrons in a molecule generally tend to repel every different to create extra area round them. The electrons that are present in an outermost electron shell for an element are known as valence electrons. They are the electrons withinside the outermost or valence shell, are vital as they offer perception into an element's chemical homes and are those gained, lost, or shared for the duration of a chemical reaction. In a metallic bond, the valence electrons are delocalized, which means that an atom's electrons do now no longer live round that one nucleus.

As you move down a group (vertical column) in the periodic table, the atomic radius tends to increase.

This is because the number of energy levels (or shells) increases as you move down a group, while the effective nuclear charge (which determines the attractive force between the nucleus and the valence electrons) remains relatively constant. As a result, the valence electrons are farther from the nucleus and the size of the atom increases. For example, as you move from top to bottom in the alkali metal group (Group 1), the atomic radius increases because the number of energy levels increases from one to seven. Similarly, as you move from top to bottom in the halogen group (Group 17), the atomic radius increases because the number of energy levels increases from two to seven.

12 ounces or 354 ml of 5% ABV beer is considered equal to one shot is 80 proof shot.

Beer that is marked as 80 proof has 40% ABV. This means that 12 oz (354ml) of 5% beer contains 0.6 oz (17.7ml) pure alcohol. The vodka shot at 1.5 Oz (44ml) has 0.6 oz (17.4ml) of alcohol. When you compare alcohol content that one regular beer is equal to one shot. Rum has been 36-50% ABV making it similar to vodka and whiskey in its alcohol content. That means that a shot of rum is going to have around 40% ABV on average. Comparatively, a single shot of rum equals a 12 oz serving of beer. light beers have almost as much alcohol as regular beer – about 85% as much.

Both water and alcohol have no color. Alcohol smell is musty while water is odorless and also salt dissolves more in waterthanalcohol

Water and alcohol both are colorless. Alcohol smells musty while water is odorless.

Salt dissolves in water more easily than alcohol because water contains both positive and negative ions. So, positive ions of water attracts negative chloride ions and negative ions of water attracts positive sodium ions while alcohol is non polar and salt is polar so that is why salt is less likely to dissolveinalcohol. And also Alcohol has less ions than water which also decreases the solubilityofsaltinit.

The total capacitive reactance of capacitor in series is equal to the sum of the reciprocal capacitor

The amount of charging a capacitor can accomplish depends on its capacitance. Capacitive reactance is a measurement of the capacitor's resistance to alternating current.

When capacitors are connected in series then the charge remains same on both the capacitors but the potential difference is different on both the capacitors.

Which gives the formula

[tex]\frac{1}{C_{s} } =\frac{1}{C_{1} } +\frac{1}{C_{2} }[/tex]

And if there are N capacitors connected in series then the total capacitive reactance is [tex](\frac{C}{N})[/tex]

The trend in ionization energy when proceeding down a group in the periodic table is that it decreases. This is because the atomic radius increases and the number of energy shells increases, making it easier to remove an electron from the atom.

This is due to the increase in atomic radius as you move down a group. As the atomic radius increases, the electrons become further away from the nucleus, making them easier to remove. As a result, the energy required to remove an electron decreases as you move down a group.

The ionization energy is the minimum energy required to remove an electron from an atom or molecular ion in the gaseous state. It is a measure of the strength of the attraction between the electron and the nucleus, and thus of the stability of the atom or ion.

The boiling point of saltwater is above the boiling point of pure water.

Separation of a solution mixture relies on the properties of the substances in the solution.

Explanation:

2H + O2 → 2 H2O is the balanced equation.

An equation for a chemical reaction is said to be balanced if both the reactants and the products have the same number of atoms and total charge for each component of the reaction. In other words, both sides of the reaction have an equal balance of mass and charge.

Copper and oxygen are the reactants because they are on the left of the arrow. Copper oxide is the product because it is on the right of the arrow.

If we just replace the words shown above by the correct chemical formulae, we will get an unbalanced equation, as shown here:

Cu+O2=CuO

Notice that there are unequal numbers of each type of atom on the left-hand side compared with the right-hand side. To make things equal, you need to adjust the number of units of some of the substances until you get equal numbers of each type of atom on both sides.

When sodium chloride is added to acid, it typically dissolves in the acid to produce a solution of hydrochloric acid and sodium ions.

This is because sodium chloride is a salt, and when it is dissolved in water, it dissociates into its constituent ions, which are sodium ions and chloride ions. When sodium chloride is added to acid, the chloride ions react with the hydrogen ions in the acid to produce hydrochloric acid, while the sodium ions remain unchanged. The reaction between sodium chloride and acid is typically exothermic, which means that it releases heat. This can be felt as a warm sensation when the sodium chloride and acid are mixed together. The heat released during the reaction can be used to drive other chemical reactions or to produce electricity in a process known as cogeneration.
