Answer:
The order is
Quartz > Calcium > Ammonia > Chlorine
Explanation:
Among given compounds
Quartz is a covalent compound with extensive bondings and thus it will have highest melting point
Calcium is a metal so it will have strong metallic bonds thus will have high melting point, however less than quartz.
ammonia is a polar molecule with weak hydrogen bond as intermolecular interactions thus will have higher melting point than chlorine
chlorine is a non polar molecule with weak intermolecular london dispersion forces.
Snow is the result of moisture and low temperatures colliding; when they collide, they become tiny ice crystals. When ice crystals stick to one another, they become snowflakes. Snow is important to the water cycle because when they precipitate to the earth, they start to melt on surfaces warmer than themselves. The melted result becomes water, and when the water either seeps into the ground or flows into a source of water nearby, the water cycle's process repeats all over again.

Answer:
Cilindros graduados
Explanation:
Son una herramienta de medición primaria para el volumen de un líquido, y tiene varias marcas hacia arriba y hacia abajo a lo largo del contenedor con incrementos específicos. Los cilindros graduados vienen en muchos tamaños; entre más pequeños sean de diámetro, más específicas serán las mediciones de volumen. Al leer el volumen de un cilindro graduado, notarán que el líquido parece tener una muesca; el líquido alrededor de los bordes será más alto que el líquido en el centro, inclinándose hacia abajo como los lados de un trampolín cuando alguien está parado en el medio. Esto se llama el menisco. Alineen el punto más bajo del menisco con la marca más cercana, manteniendo el nivel del cilindro para leer correctamente el volumen.
Answer:
The new volume of this gas is 6.86 liters.
Assumption: the temperature of this gas stays the same, and this gas is ideal such that Boyle's Law applies.
Explanation:
By Boyle's Law, the volume of an ideal gas shall be inversely proportional to the pressure on it when temperature stays the same (as in an isothermal process.)
In other words,
,
where
is the volume of the gas, and
is the pressure on the gas.
.
.
Assume that this gas is ideal. Also assume that this increase in pressure is isothermal. Apply Boyle's Law to find the new volume of this gas:
.
Actually, a methylene group is simply any compound which
contains a C=C double bond group and the rest are single bonded carbon groups. Some
example of the isomers of C6H12 which contains methylene group is:
1-hexene
2,3-dimethyl-2-butene
2,3-dimethyl-1-butene
2-methyl-2-pentene
trans-2-hexene
4-methyl-1-pentene
cis-2-hexene
trans-3-hexene
2-ethyl-1-butene
2-methyl-1-pentene
3,3-dimethyl-1-butene
4-methyl-cis-2-pentene
cis-3-methyl-2-pentene
trans-3-methyl-2-pentene
