What is the process called to prepare a ceramic by heating a slurry of a powder of an inorganic substance in water to a very hig

Zolol [24]

Answer: The process that is used to prepare ceramic is sintering.

Explanation:

Sintering is defined as the process in which number of particles are fused together to form one solid mass by the applying pressure at high temperatures.

Ceramic is an material that is made by taking mixtures of clay, earthen elements, powders and water.

When this mixture (slurry of the powders) is heated at a very high temperature and under high pressure, ceramic is formed.

Hence, the process that is used to prepare ceramic is sintering.

A 0.98 gram sample of a volatile liquid was heated to 348 k. the gas occupied 265 ml of space at a pressure of 0.95 atm. what is

arlik [135]

Answer:

The molecular weight is $Z = 111.2 \ g/mol$

Explanation:

From the question we are told that

The mass of the sample is $m = 0.98 \ g$

The temperature is $T = 348 K$

The volume which the gas occupied is $V = 265 \ ml = 265 *10^{-3} L$

The pressure is $P = 0.95 \ atm$

Generally from the ideal gas equation we have that

$PV = n RT$

Here n is the number of moles of the gas while the R is the gas constant with value $R = 0.0821 \ atm \cdot L \cdot mol^{-1} \cdot K^{-1}$

$n = \frac{PV}{ RT}$

=> $n = \frac{ 0.95 * 265 *10^{-3} }{ 0.0821 * 348}$

=> $n = 0.00881 \ mol$

Generally the molecular weight is mathematically represented as

$Z = \frac{m}{n}$

=> $Z = \frac{0.98 }{0.00881}$

=> $Z = 111.2 \ g/mol$

Which of the following conversion factors would be used to calculate the number of moles of Cl2 produced if 11 moles of HCl were

MissTica

Answer: The moles of chlorine gas produced is 5.5 moles

Explanation:

We are given:

Moles of HCl = 11 moles

For the given chemical reaction:

$4HCl+O2\rightarrow 2Cl_2+2H_2O$

By Stoichiometry of the reaction:

4 moles of HCl produces 2 moles of chlorine gas

So, 11 moles of HCl will be produced from $\frac{2}{4}\times 11=5.5mol$ of chlorine gas

Hence, the moles of chlorine gas produced is 5.5 moles

Complete and balance the equations for the given single displacement reactions. Write the reaction in molecular form. Phases are

Elan Coil [88]

Answer:

Li(s) + H2O(l) -----> LiOH(aq) + H2(g)

Ca(s) + 2H2O(l) ---------------> Ca(OH)2(aq) + H2(g)

Explanation:

Metals react with water to yield the metal hydroxide and hydrogen gas as shown in the answer above.

The reaction equations were balanced, the number of atoms of each element on both side of the reaction equation is exactly the same.

This is the way to write a balanced reaction equation for the species shown in the question.
