What characteristic of a solid is most responsible for their structure?
jekas [21]

The characteristics of solids that is most responsible for their structure are:

1. BONDING PATTERNS BETWEEN ATOMS.

2. TYPES OF MATTER IN SOLIDS.

Solid state is one of the four states of matter that exist; the other three are liquid, gas and plasma. Solids generally have their constituent particles arranged in a regular pattern, which is known as crystalline structure. The crystalline structure of the solid is due to the types of matter and the chemical bonds that exist between the particles of solids. The constituent particles of a solid can be atoms, ions or molecules.

In the gaseous state, chlorine exists as a diatomic molecule Cl2 (Molar mass = 70.9 g/mol). Calculate the number of moles of chl
Annette [7]

Answer:

3.67 mol Cl

Explanation:

We need to convert g of Cl 2 to moles of Cl. First we divide 130 gCl2  by the molar mass (70.90 gCl2/mol) to find out how many moles of Cl2 do we have.

130 gCl2 x \frac{1 mol Cl2 }{70.90 gCl2} = 1.83 mol Cl2

Then we need to convert 1.83 mol de Cl2 to moles of Cl. We have 2 moles of Cl in every Cl2 molecule so we just need to multiply by 2.

1.83 molCl2 x \frac{2 molCl}{1 molCl2} = 3.67 molCl

pentagon [3]

The answer is A. Volcanoes and earthquakes often occur near place boundaries. Volcanoes are exit points for heat from the Earth's core. And Earthquakes are caused by the tectonic places colliding along another one. For example one tectonic plate would be slowly moving south, and another next to it could collide with the South-going plate while going North, and that is what causes Earthquakes.

What effect does rapid exhalation of CO2 during exercise have on the concentration of H2CO3 in the blood?
BARSIC [14]

If there is a constant loss of CO_{2}~(carbon~dioxide) the concentration of H_{2} CO_{3}~(carbonic~acid) will be affected and decrease since CO_{2} is a main component of H_{2}CO_{3}.


Hope it helped,

Last question<br> help<br> im confusion
Andrej [43]

Remark

The given thing on the right is a positron. The mass for these subatomic particles is considered to be 0. It's atomic number is 1 which means it is a blood relative of a proton.

So essentially what happens is that X is one space to the left on the periodic table. But let's solve this a little bit more formally.

Solution

_{65}^{147}\text{Tb}\longrightarrow _{z}^{y}\text{x} +_{1}^{0}{e}

y stays the same at 147. It is z that changes.

65 = z + 1     Subtract 1 from both sides.

64 = z

So the chemical with 64 as its position on the periodic table is
