Por que un solido mantiene su forma?

1 answer:

3 0

La materia en estado sólido se resiste por lo general a la deformación: las torceduras, los dobleces, las hendiduras, incluso en presencia de fuerzas constantes como el peso o la gravedad. Sólo si dicha resistencia es vencida, los sólidos cambian de forma (permanente o temporalmente, dependiendo de su elasticidad).

A 38-lb child is prescribed acyclovir for chicken pox in an amount of 80 mg/ kg body weight per day to be divided in four doses

Svetach [21]

Answer:

$\large \boxed{\text{Two tablets per day; half a tablet per dose}}$

Explanation:

1. Convert pounds to kilograms

$\text{Body weight} = \text{38 lb} \times \dfrac{\text{1 kg}}{\text{2.205 kg}} = \text{17.2 kg}$

2. Convert kilograms of body weight to milligrams of acyclovir

$\text{Mass of acyclovir} = \text{17.2 kg} \times \dfrac{\text{80 mg acyclovir}}{\text{1 kg}} = \text{1380 mg acyclovir }$

3. Convert milligrams of acyclovir to number of tablets

$\text{No. of tablets} = \text{1380 mg} \times \dfrac{\text{1 tablet}}{\text{700 mg}} = \textbf{2 tablets}$

4. Calculate the tablets per dose

The child must receive two tablets in four doses.

$\text{Tablets per dose} = \dfrac{\text{2 tablets}}{\text{4 doses}} = \textbf{0.5 tablets per dose}\\\\\text{The child must receive $\large \boxed{\textbf{two tablets per day and half a tablet per dose}}$}$

What does the law of conservation of energy impy

Rasek [7]

The law of conservation of energy is that energy cannot be created or destroyed, but it can be transferred or transformed from one form to another (including transformation into or from mass, as matter). The total amount of energy in a closed system never changes. energy in a system may be transformed so that it resides in a different state.

PLEASE HELP WILL GIVE BRAINLIEST!!!

IrinaVladis [17]

Answer:

The light emitted by a light bulb is a form of radiation that occurs when the filament heats up and its thermal emission gains enough energy to move into the visible spectrum.

Explanation:

Light bulbs contain a filament which is heated up electrically. When this filament is heated up,energy in the form of heat is imparted to the electrons in the filament.

This thermal excitation of electrons ultimately leads to emission of light in the viable spectrum. This light is now radiated through a light bulb.

Consider these reactions:

Virty [35]

511.2 grams of chlorine gas consumed (with excess H-) when

1,342.0 kJ of energy is released from the system.

<h3></h3><h3>What is an exothermic reaction?</h3>

In thermochemistry, an exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative."

Given that 1 mole of chlorine releases -184.6 energy.

Then, we have to find the number of moles of chlorine when 1,342.0 kJ of energy is released from the system.

So, calculating number of moles of chlorine.

Moles = $\frac{-1,342.0 \;kJ}{-184.6\;kJ}$

Moles = 7.2 mole

Now, calculating number mass of chlorine.

$\rm Moles=\rm\frac{Mass}{Molar \;mass}$

Mass = 7.2 mole x 71 g/mole

Mass = 511.2 gram
