vekshin1

Answer:

See explanation

Explanation:

We know that photosynthesis involves the combination of carbon dioxide and water in the presence of sunlight to yield glucose.

If the atmosphere is rich in carbon dioxide such as  in a green house where air is filled with carbon dioxide, the rate of photosynthesis is increased.

As the rate of photosynthesis is increased, the growth of plants is also increased.

Hence, in a greenhouse where the air contains more carbon dioxide, the rate of plant growth increases.

If 5.4 g of NaNO3 is dissolved in 350 mL of water, what is the molarity of the solution?
Aleonysh [2.5K]

Answer:

0.18 Moles

Explanation:

first you need to convert the 5.4g to moles using molar mass

(\frac{5.4g}{1})(\frac{1mol}{84.99g} )=\frac{5.4g}{84.99g} =0.0635mol NaNO_{3})

once you have that done you can use the molarity equation to get the answer

M=\frac{0.0635mol}{0.350ml} =0.181428

now you need to round to the correct sig fig which will give you the correct answer of 0.18moles

Be sure to answer all parts. Liquid nitrogen trichloride is heated in a 3.00−L closed reaction vessel until it decomposes comple
iris [78.8K]

Answer:

p_{Cl_2}=629.25mmHg\\p_{N_2}=209.75mmHg

Explanation:

Hello,

At first, consider the chemical reaction:

2NCl_3-->3Cl_2+N_2

Now, considering the ideal gas equation, we compute the total moles:

PV=nRT\\n=\frac{PV}{RT} \\n=\frac{839mmHg*\frac{1atm}{760mmHg}*3L }{0.082\frac{atm*L}{mol*K}*359K }\\ n=0.1125mol

Then, taking into account that the total moles are stoichiometrically handed out by the half (0.05625mol), one can say that:

n_{Cl_2}=0.05625molNCl_3*\frac{3mol Cl_2}{2molNCl_3} =0.084375molCl_2\\n_{N_2}=0.05625molNCl_3*\frac{1mol N_2}{2molNCl_3} =0.028125molN_2

Thus, the molar fractions are:

x_{Cl_2}=\frac{0.084375}{0.1125} =0.75\\x_{N_2}=\frac{0.028125}{0.1125} =0.25

Finally, the partial pressures are:

p_{Cl_2}=x_{Cl_2}P=0.75*839mmHg=629.25mmHg\\p_{N_2}=x_{N_2}P=0.25*839mmHg=209.75mmHg

Best regards.
