Answer:

2.853881279 years

Explanation:

I multiplied 365 times 24 to get 8760 hours in a year. I then multiplied this by 60 to get 525600 seconds per year. Lastly, I divided 1500000 by 525600 in order to get the answer. Hope this helps!

What is the mole fraction of urea, CO(NH2)2, in a solution prepared by dissolving 4.0 g of urea in 32.0 g of methanol, CH3OH
earnstyle [38]

Answer:

0.0630

Explanation:

The molar mass of urea = 60 g/mol

we all know that:

\mathtt{number \ of  \ moles = \dfrac{mass }{molar \ mass}}

Then; the number of moles of urea

= \mathtt{\dfrac{4.0 \ g}{60 \ g/mol}}

= 0.0667 mol

Similarly; the number of moles of methanol

= \mathtt{\dfrac{32 \ g}{32.04 \ g/mol}}

= 0.9988 mol

The total number of moles = (0.0667 + 0.9988) mol

= 1.0655 mol

Finally,the mole fraction of urea  \mathtt{(X_{urea})} = \mathtt{\dfrac{ n_{urea}}{(n_{urea}+n_{methanol})}}

\mathtt{(X_{urea})} = \mathtt{\dfrac{0.0667 \ mole}{1.0655 \ mole}}

= 0.0630

Please help . also need the name of their binary ionic compound . ​
madreJ [45]

Answer:

See below!

Explanation:

For the chemical formula, you need to have enough of each atom so that the charge is zero.

Aluminum has a +3 charge, and fluorine has a -1 charge.  Since the charge has to be zero, you need three fluorines, giving you AlF₃.

Barium has a +2 charge, and oxygen has a -2 charge.  Since the charges are equal in magnitude but opposite in sign, you only need one of each atom giving you BaO.

The name of the ionic compound will be the metal and then the nonmetal.  When putting the nonmetal in, change the ending to "-ide".  For example "chlorine" would be "chloride.

CaCl₂  ==>  calcium chloride

Ga₂S₃  ==>  gallium sulfide

K₃N  ==>  potassium nitride

AlF₃ ==>  aluminum fluoride

BaO  ==>  barium oxide

Write a balanced chemical equation with state symbols to illustrate how NaNO, can be
erastovalidia [21]
Mark Brainliest please

Answer:

Neutralization of nitric acid with sodium hydroxide makes it possible to obtain sodium nitrate in the laboratory in its pure form.

HNO3 + NaOH → NaNO3 + H2O

NaNO3 cannot be prepared utilizing the same method used for the preparation of CaCO3, because calcium carbonate is not soluble in water, and sodium nitrate is soluble in water.
