Answer: metal and carbonate

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions (OH^-) when dissolved in water and an acid is defined as a substance which donates hydrogen ions (H^+) in water.

An acid is represented as :

HX\rightarrow H^++X^-

1. When metal is treated with an acid such as HCl, if the metal is more reactive than hydrogen displaces hydrogen from its salt solution and thus produce zinc chloride and hydrogen gas.

M+xHCl(aq)\rightarrow MCl_x(aq)+xH_2(g)

2. When carbonates are treated with acid, double displacement takes place ad carbon dioxide is released as a gas.

MCO_3(aq)+xHCl(aq)\rightarrow MCl_x(aq)+xH_2O(l)+CO_2(g)

Which statement correctly identifies the nuclide that is most likely to be unstable and describes why?
iVinArrow [24]
The answer would be B.

U-238 has a n to p ration of 1.6:1. 146 neutrons and 92 protons.

It is actually the most commonly used isotope is reactors.

C-14 is also a radioactive isotope with 8 neutrons and 6 protons.

The usual and ideal n to p ratio is 1:1 such as C-12 or Mg-24

Describe the spin of carbon-14's valence electrons and explain how you came about your answer.
Snezhnost [94]

we have to know the spin of valence electrons of carbon-14

There are four unpaired electron which are called as valence electron also.The spin of the four unpaired electron is either upfilled or down filled.

The ground state electronic configuration of C-atom is 1s²2s²2p² and one electron from 2s orbital gets excited to 2p orbital. The elctronic configuration in excited state is 1s²2s¹2p_{x}^{1} 2p_{y}^{1}2p_{z}^{1}.

The electron jumps because half-filled orbitals are more stable. Exchange energy is less than pairing energy.

the table shows the types of elements that form two componds. which of the following statements is true about how the bonding oc
Grace [21]

Electrons are shared in compound X and transferred in compound Y.

<h3>Further explanation  </h3>

1. ionic bonding  

Bonding that occurs due to electron transfer. Can occur in metal and non-metal atoms. To get stability, atoms release or bind electrons to get stable electron regulation from noble gases  

2. covalent bonding  

Bonding that occurs due to shared use of electron pairs  

The two bound atoms contribute their electrons to produce bonds  

Generally occurs in non-metallic elements  

So compound X = covalent bond (metal with metal) and compound Y= ionic bond(metal with non metal)

  • Compound X : shared electron
  • Compund Y : transferred electron
