Answer:The nucleus emits particles and/or energy.

Explanation:

The density of the rectangular block is 1.07 g/mL.

From the question, we have the mass of the rectangular block as 121g

The dimensions of the block are given as follows;9.1cm by 5.4cm by 2.3cm

So we have the volume of the block as; 9.1cm × 5.4cm ×  2.3cm = 113 cm^3

Let us recall that; 1 cm^3 = 1 mL, so 113 cm^3 = 113 mL

Having said that, we must also remember that;

Density = Mass/volume

Density = 121g/113 mL

Density = 1.07 g/mL

The given oxygen and lithium atoms are unable to form a stable compound.

The given atoms to form a stable compound has been oxygen and lithium.

A stable compound has been formed when the transfer of atom has been resulted in the completion of the valence shell of both the electrons.

The oxygen has 6 valence electrons and require to gain 2 electrons to form the stable compound. The Lithium has 3 electrons and has been able to lose 1 electron to form a stable compound.

Since, the formation of stable compound between oxygen and lithium requires transfer of 2 electrons, and there has been availability of 1 electron from Li. Thus, the atoms are unable to form a stable compound.

Explanation:

1. Earthquakes and Eruptions (volcanoes)

2. Divergent plate boundary

3. Apart from a widening valley, it equally contributes to steep mountain sides spreading. A mid-oceanic ridge is naturally produced if two oceanic plates naturally start moving away from each other.

1. When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below. It responds by melting, and the new magma flows into the fissure. The magma then solidifies and the process repeats itself.

2. When two plate diverge from each other also known as divergent (di-apart, vergere- to inclined) plate margin .

Two plate diverge along oceanic ridges where new lithosphere is created.

Now come to the main point: Geological Features

When two oceanic plate diverge then new sea floor is created by a process called sea floor spreading and features like Mid oceanic ridges, volcanoes & Young lava flows forms. Ex. East Pacific Rise, Mid-Adlantic Ridge.

When two continental plates diverge by continental rifting then features like Rift valley, volcanoes are found. Ex of continent continent -East Africa rift vally, Red sea.

3. The major difference between different types is what type of plate the divergent boundary is between. If the boundary is found between two continental plates you are left with a rift valley. ... If two oceanic plates begin moving away from each other it creates a mid-oceanic ridge.

There are 500 mg of calcium carbonate is in this caltrate tablet

The equation of the reaction is;

2HCl(aq) + CaCO3(aq) ------> CaCl2(aq) + CO2(g) + H2O(l)

Next, we have to obtain the amount HCl reacted as follows;

Number of moles = concentration × volume

Volume = 34.46 mL or 0.03446 L

Concentration =  0.291 M

Number of moles = 0.291 M ×  0.03446 L

Number of moles = 0.01 moles

Since the reaction of HCl and CaCO3 are in the ratio of 2:1

2 moles of HCl reacts with 1 mole of CaCO3

0.01 moles of HCl reacts with  0.01 moles ×  1 mole/2 moles

= 0.005 moles of CaCO3

Mass of CaCO3 = number of moles  × molar mass

Mass of CaCO3 =  0.005 moles of CaCO3 × 100 g/mol

Mass of CaCO3 =  0.5 g or 500 mg

The final pressure of the gas mixtures is 72.48 atm.

The given parameters;

The number of moles of the gases is calculated as follows;

[tex]number \ of \ moles \ of \ oxygen = \frac{88}{16} = 5.5 \ moles\\[/tex]

[tex]number \ of \ moles \ of \ argon = \frac{33}{40} = 0.825 \ moles\\[/tex]

The total number of moles of the gas mixture;

= 5.5 + 0.825

= 6.325 moles

The final pressure of the mixture is calculated as follows;

PV = nRT

[tex]P = \frac{nRT}{V} \\\\P = \frac{6.325\ mol \times (0.0821 \ L.atm/mo.K) \times (62+273)}{2.4 \ L} \\\\P = 72.48 \ atm[/tex]

Thus, the final pressure of the gas mixtures is 72.48 atm.

Answer:

This isotope has 59 electrons giving it a charge of -2.

Explanation:

To find this we have to understand isotope relates to the mass of the nucleus. This isotope has 59 electrons to counter the protons and give it a negative charge.

In an atom, the atomic number is equal to number of electrons , hence element Q has 57 electrons on addition 2 electrons that is -2 charge the number of electrons is 59 electrons.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.
