Answer:

Mass of copper vaporized is 52,8g

Explanation:

The heat of vaporization (ΔHvap) is defined as the amount of energy you require to transform a quantity of liquid in gas. The formula is:

Q = ΔHvap×mass

Where Q is the amount of heat and mass is the mass of the compound.

If you required 254 kJ to vaporize a sample of copper which heat of vaporization is 4,81 kJ/g:

254kJ = 4,81 kJ/g × mass of copper

<em>52,8g = mass of copper</em>

<em></em>

I hope it helps!

Consider the reaction H2(g) + Cl2(g) &lt;=&gt; 2 HCl(g), which is exothermic as written. What would be the effect on the equilib
kirill115 [55]

Answer:

No effect

Explanation:

H2(g) + Cl2(g) <=> 2HCl(g)

Decreasing the volume of the re simply means increasing the pressure. As we can see from the above equation, the total number of moles of the reactants and products are the same. There decreasing the volume ( i.e increaing the pressure) will have no effect on the system and hence the equilibrium position is not affected.

jeyben [28]

Answer:

5.6\frac{6.02*10^{23} }{1} = 3.4 X 10^{24}

Explanation:

the correct answer to it is 3.4 instead of 3.2. I got 3.4 from rounding it from 3.37.

Frank has a sample of steel that weighs 80 grams. If the density of his sample of steel is 8 g/cm3, what is the sample’s volume?
IRINA_888 [86]
Density (p) is defined as the mass (m) per unit volume (v) or:

p = m/v 

Using this relationship, the volume is:

v = m/p

Using the given values of mass of 80 grams and density of 8 g/cm3, the sample volume is:

v = 80 grams/8 grams/cm3
v = 10 cm3

The final answer is 10 cm3.

Genes are sections of DNA that code for a particular trait. Genes are ?
Burka [1]

Hello! Allow me to help!

Your question: Genes are ?

My answer: In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function

Why is my answer correct? Good question! Allow me to explain: A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. An international research effort called the Human Genome Project, which worked to determine the sequence of the human genome and identify the genes that it contains, estimated that humans have between 20,000 and 25,000 genes.

Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

Scientists keep track of genes by giving them unique names. Because gene names can be long, genes are also assigned symbols, which are short combinations of letters (and sometimes numbers) that represent an abbreviated version of the gene name. For example, a gene on chromosome 7 that has been associated with cystic fibrosis is called the cystic fibrosis transmembrane conductance regulator; its symbol is CFTR.

Hope this helps! UwU
