Answer:

im not sure but I hope this helps

Explanation:

I believe the equivalents is just the moles reactant/moles limiting reactant

water has a denisty of 1 g/mL. 1 L is 1000 ml so there are 1000g/L.

the molar mass of water is 18g/mol if you use the Liters in the equation above you can find the number of grams present. divide this number you found by 18 to find the moles.

now take the amount of the other reactant given and divide it by its own molar mass. this will give you the number of moles of that reactant.

divide the moles of water by the moles of the reactant and that is the equivalent.

to find the normality you take this number and divide it by the number of liters.

calculate the number of moles of gas that occupy a 3.45L container at a pressure of 1.48 atm and a temperature of 45.6 Celsius ​
Otrada [13]

Answer:

There are 0,2 moles of gas that ocuppy the container.

Explanation:

We apply the formula of the ideal gases, we clear n (number of moles); we use the ideal gas constant R = 0.082 l atm / K mol. Firs we convert the unit of temperature in Celsius into Kelvin:

0°C= 273 K ------> 45,6 °C= 273 + 45, 6= 318, 6 K

PV= nRT ---> n= PV/RT

n= 1,48 atm x 3,45 L /0.082 l atm / K mol x 318,6 K

n= 0,195443479 mol

14.americium- 241 is widely used in smoke detectors. the radiation released by this element ionizes particles that are then dete
avanturin [10]

Hence, 5.1 * 10^-11 alpha particles is being emitted each second by the sample.

<h3>What is half life?</h3>

The term half life is the time taken for only half of the original  amount of radioactive nuclides to remain.

Thus, we have that the half life is 432.2 years or 1.36 * 10^10 s.

k = 0.693/ 1.36 * 10^10 s

k = 5.1 * 10^-11 alpha particles per second.

Match each term with its correct description:
Artemon [7]

Answer:

Explanation:

Hydrocarbon:

a = An organic compound made up of only carbon and hydrogen.

Such as alkane, alkene, alkyne.

Cyclic hydrocarbon:

c = Carbon chain that form rings.

Such as benzene, cyclo heptane etc

Isomers:

d = Compounds with same molecular formula and different structural formula.

Alkanes:

e = refers to saturated hydrocarbons, no matter the shape

such as methane, ethane, propane etc.

Alkene:

f = Any hydrocarbon that have at lest one carbon carbon double bond.

such as ethene, propene, butene

Saturated hydrocarbons:

b = Carbon atoms are saturated with so many hydrogen atoms that no more bonds may be formed

such alkanes.
