What forces hold network solids together?

Chemistry

Answer:

Covalent solids, also called network solids, are solids that are held together by covalent bonds. As such, they need localized electrons (shared between the atoms) and therefore the atoms are arranged in fixed geometries. Distortion far from this geometry can only occur through a breaking of covalent sigma bonds.

Name some ways that friction can be helpful and some ways it is harmful?

jeka57 [31]

Friction is helpful:
- We use it to brake for cars
- We use it to fly planes
-We wouldn't be able to turn a door knob without friction ( Our hand would just slide off it)

Friction harmful:
-Our cars would get much better gas mileage without tire and air friction
- There would be no skinned knees if friction didn't exist (Like when your skating or football)
- We could do some pretty cool dance moves without friction
- Our shoes would last longer without friction

What kind of change happens when liqiud becomes solid?

Viefleur [7K]

Answer:

freezing

Explanation:

The process in which a liquid changes to a solid is called freezing. The temperature at which a liquid changes to a solid is its freezing point. The freezing point of water is 0°C (32°F). Other types of matter may have higher or lower freezing points.

Calcule la masa en gramos de cloruro de hidrógeno (HCl) que se forma cuando 5.6 L de hidrógeno molecular, medido a TPE, reaccion

AveGali [126]

Calculate the mass in grams of hydrogen chloride (HCl) that is formed when 5.6 L of molecular hydrogen, measured at TPE, reacts with an excess of gaseous molecular chlorine. MHCl = 36.5 g/mol

H2(g) + Cl2(g) → 2HCl(g)

Answer:

18.25g

Explanation:

The reaction equation is given as;

H₂ + Cl₂ → 2HCl

Given parameters:

Volume of hydrogen gas = 5.6L

The reaction occurs at STP.

Solution:

To solve this problem, let us find the number of moles of the hydrogen as;

At STP;

22.4L of a gas has 1 mole;

5.6L of Hydrogen as will have $\frac{5.6}{22.4}$ = 0.25mole

From the balanced reaction equation;

1 mole of H₂ will produce 2 mole of HCl

0.25 mole of H₂ will produce 2 x 0.25 = 0.5mole of HCl

The mass of HCl';

Mass of HCl = number of moles x molar mass

Mass of HCl = 0.5 x 36.5 = 18.25g
