Match the following:

chubhunter [2.5K]

Answer:

1. a chemical reaction in which one substance breaks up into two or more new substances: decomposition reaction

2. a reaction in which two or more substances combine to form a new substance: synthesis reaction

3. the reaction of an acid with a base to form a salt and water: neutralization reaction.

4. chemical compound formed when the negative ions from an acid combine with the positive ions of a base: salt

5. two ionic compounds reacting in solution to form two new compounds, one of which is insoluble: double displacement reaction.

6. a reaction in which an active metal displaces a less active metal or hydrogen from a compound solution (or a nonmetal replaces a nonmetal from a compound in solution): Single replacement reaction

Explanation:

1. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Example: $Li_2CO_3\rightarrow Li_2O+CO_2$

2. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

Example: $Li_2O+CO_2\rightarrow Li_2CO_3$

3 and 4. Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water. Salt is formed when cations or positive ions of base combine with anions or negative ions of acid.

Here $KCN$ is the salt formed by combination of $K^+$ from base and $CN^-$ from acid.

Example: $H^++CN^-+K^++OH^-\rightarrow K^++CN^-+H_2O$

5. A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

Example: $2NaOH(aq)+(NH_4)_2SO_4(aq)\rightarrow 2NH_4OH(aq)+Na_2SO_4(aq)$

6. Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

Example: $Zn+2HCl\rightarrow ZnCl_2+H_2$

A mixture of h2 and n2 has a density of 0.216 at 300k and 500 torr. what is the mole fraction composition of the mixture

natta225 [31]

We know that:
number of moles (n) = mass / molar mass

Now, from the general law of gases:
PV = nRT
where:
P is the pressure = 500 torr = 0.65 atm
V is the volume
n is the number of moles
R is the gas constant = 0.082
T is the temperature = 300 k
We will just rearrange this equation as follows:
P = nRT / V
Then we will substitute n with its equivalent equation mentioned at the beginning:
P = (mass x R x T) / (volume x molar mass) ......> equation I
Now, we know that:
density = mass / volume
We will substitute (mass/volume) in equation I with density as follows:
P = (density x R x T) / molar mass
Rearrange this equation to get the mass as follows:
molar mass = dRT/P = (0.216 x 0.082 x 300) / 0.65 = 8.4738 grams

From the periodic table:
molecular mass of hydrogen = 1 grams
molecular mass of nitrogen = 14 grams
Therefore:
molar mass of hydrogen = 2 x 1 = 2 grams
molar mass of nitrogen = 2 x 14 = 28 grams

We can assume that the number of moles of of each element is y.
We can thus build up the following equation:
2y + 28y = 8.4738
30y = 8.4738
y = 0.28246

Therefore:
mole fraction of hydrogen = 2 x 0.28246 = 0.56492
mole fraction of nitrogen = 28 x 0.28246 = 7.90888

If a computer adds together a list of numbers, what term identifies these numbers?

yawa3891 [41]

If a computer adds together a list of numbers, the term that identifies these numbers is data.
Data is any type of information, especially information created using the computer or any other type of electronic device.
