A gaseous mixture contains 5.0 moles of nitrogen and 10.0 moles of helium . What is the total pressure if the temperature is 25
jolli1 [7]

Answer:

A) 122 atm

Explanation:

PV = nRT

Solve for P --> P = nRT/V

n = 10.0 mol + 5.0 mol = 15.0 mol

R = 0.08206 L atm / mol K

T = 25 + 273 = 298 K

V = 3.0

P = (15.0)(0.08206)(298) / (3.0) = 122 atm

38.5 mol of P4O10 contains how many moles of P?
stellarik [79]

The subscripts tell the ratio of one element to another in a compound. In this case, there are 4 P atoms per 10 O atoms. This could also be interpreted as 4 mol P per 10 mol O. Therefore:

Mol P = (38.5 mol P4O10)/(4 mol P/ 1 mol P4O10) = 154 mol P

A piece of charcoal is found to contain
Naddika [18.5K]

Answer: The tree died 9709.46 years before.

Explanation:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant  

t = age of sample

a = let initial amount of the reactant = 100

a - x = amount left after decay process = \frac{30}{100}\times 100=30

a) to find rate constant

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

t_{\frac{1}{2}}=\frac{0.693}{k}

k=\frac{0.693}{5600years}=1.24\times 10^{-4}years^{-1}

b) to know the age

t=\frac{2.303}{1.24\times 10^{-4}}\log\frac{100}{30}

t=9709.46years

The tree died 9709.46 years before.
