Answer:

The answer to your question is the second one

Explanation:

AC + B → AB + C

This is not the right answer, the reaction shown here is a single replacement reaction in which one element replaces another element that is part of a compound.

A + B + C → ABC

This is the right answer because in synthesis reactions two or more reactants bound to form only one product.

ABC → A + B + C

This answer is incorrect because this is an example of a decomposition reaction in which one reactant forms two or more products.

AB + CD → AC + BD

This is an example of double replacement reaction in which the cations and anions of the reactants are interchanged.

Why is it that in Group 1 elements become more reactive as we go down the group but in Group 7 elements become less reactive as

wariber [46]

Answer:

Group 1 elements become more reactive as we move down the group. These atoms are larger because they have more shells. ... The force of attraction between the nucleus and the electron is less than for smaller atoms, and the outer electron is lost more easily.

Using the particle-in-the-box model for the hydrogen atom and treating the atom as an electron in a one-dimensional box of lengt

Levart [38]

The model has resulted into a formula called the Rydberg formula. It also came about from the electron transfer within the hydrogen atom. The formula is shown in the picture, where RH is the Rydberg constant and λ is the wavelength . Thus, the solution is as follows:

1/λ = (1.0973731×10⁷ m⁻¹)(1/2² - 1/3²)
Solving for λ,
<em>λ = 6.56×10⁻⁷ m</em>

A gas sample in a closed, expandable container of initial volume 5.00 l was allowed to warm from 25 °c to 35 °

mylen [45]

Charles law states that volume of gas is directly proportional to temperature of gas at constant pressure and fixed amount of gas.
V / T = k
where V - volume , T - temperature in Kelvin and k - constant
$\frac{V1}{T1} = \frac{V2}{T2}$
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 = 25 °C + 273 = 298 K
T2 = 35 °C + 273 = 308 K
substituting values in the equation,
$\frac{5.00L}{298 K} = \frac{V}{308 K}$
V = 5.17 L
new volume is 5.17 L
