Answer:

Same charge.

Explanation:

Ions in the same group tend to form ions with the same charge. Elements belong to the same group on the periodic table form ions with the same charge because they have the same number of valence electrons. For example, all members of alkali metals have different number of shells but same number of electrons in their outermost shell so due to same number of outermost shell these alkali metals will make bonding with halogens which is a seven group that have seven electrons and needs one electron for attaining stability and forming ions on both atoms.

Which statement is correct regarding the reaction ?

larisa86 [58]

The true statement is that after reaching equilibrium, the rate of forming products and reactants is the same.

<h3>What is true about the given reaction?</h3>

The given reaction shows a reaction between A and B to form CD

The reaction is a reversible reaction.

A reversible reaction is a reaction which can proceed in either of two ways where the reactants can react to form the product and also the products an break down to form the reactants.

In the reaction given, as the concentration of A and b decreases, the concentration of CD increases and vice versa.

At equilibrium, the rate of formation of CD is equal to the the rate of decomposition of CD.

Therefore, the true statement is that after reaching equilibrium, the rate of forming products and reactants is the same.

In conclusion, a reaction at equilibrium has the forward and backward reactions occurring at the sane rate.

A sample of gas in a 14.6 L flexible container is at 25.0oC and 1.00atm. What is the volume of the sample when heated to 220.0oC

inn [45]

Answer: 24.1 L

Explanation:

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=14.6L\\T_1=25.0^oC=(25+273)K=298K\\V_2=?\\T_2=220.0^0C=(220+273)K=493K$

Putting values in above equation, we get:

$\frac{14.6}{298K}=\frac{V_2}{493}\\\\V_2=24.1L$

Thus the volume of the sample when heated to 220.0oC and the pressure is constant is 24.1 L

A)The lower the greenhouse gases, the higher the ocean temperature.

HACTEHA [7]

The higher the greenhouse gases, the higher the ocean temperature

"The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures"

A solution is made by dissolving 85.0 mL of sodium fluoride to water until the final volume is 350.0 mL. Identify the solute in

Natasha_Volkova [10]

Answer:

Sodium fluoride

Explanation:

A solution is constituted by two parts: the solute and the solvent (there may be more than 1 solute and more than 1 solvent, but that is not the key of the answer).

Solute is the substace that is dissolved and it is in less amount than the solvent.

Solvent is the substance that can dissolve the solute and it is a greater amount than the solute.

In the given solution:

sodium fluoride, 85.0 mL, is the solute,
water, 350.0 mL is the solvent, and
the mixture of both substances is the solution.
