The 2 indicates the amount of hydrogen there is. In this case there are two atoms of hydrogen. The subscript will correspond to the “letter” (element symbol) right before it.

Black_prince [1.1K]

Answer:

Goodness of fit

Explanation:

The goodness of fit - it is proposed by Thomas and chess in 1977. This term is used to defined coordination of child temperament and environment. while poorness of fit defines when temperament is not accommodated.

The goodness of fit is generally good for children's best learning. it is basically related to individual temperament and their social environment

If 44.7 g of KCI (MM = 74.55 g/mol) are added to a 500.0 mL volumetric flask, and water is added to fill the flask, what is the
navik [9.2K]

1.199 M is the concentration of KCI in the resulting solution.

<h3 /><h3>What are moles?</h3>

A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

No.of moles of KCI

Moles = \frac{mass}{molar \;mass}

Moles = \frac{44.7 g}{74.5513 g/mol}

= 0.599 moles

Vol.of the solution,V= 500 ml

= 0.5 liter

Molarity

Molality = \frac{Moles \;solute}{Volume \;of \;solution \;in \;litre}

Molality = \frac{0.599 moles}{0.5 liter}

= 1.199 M

Hence, 1.199 M is the concentration of KCI in the resulting solution.

What kind of feature results from the convergence of two oceanic plates?
Liono4ka [1.6K]

Answer: When a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate begins to melt.

Elements are organized on the periodic table based on their properties. Which statement correctly predicts and explains the chem
Elanso [62]

Answer is: a. Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons.

The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).  

Alkaline metals (group 1), in this example rubidium, have lowest ionizations energy and easy remove valence electrons (one electron), they are most reactive metals.

Earth alkaline metals (group 2), in this example strontium, have higher ionization energy than alkaline metals, because they have two valence electrons, they are less reactive.  

Rubidium electron configuration: ₃₇Rb 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶5s¹; one valence electron is 5s¹ orbital.

Strontium electron configuration: ₃₈Sr 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶5s²; two valence electrons is 5s² orbital.
