Answer: Option B

Explanation:

The chloroplast are the cell organelles that has the primary function of photosynthesis. The photosynthetic pigment chlorophyll captures sunlight and converts it into chemical energy.

The food that is used by the plants is made by this process. The food is also stored in the plant species in the form of starch.

The food stored n the plants is used by the animals and human beings. The process of photosynthesis is very essential for maintaining life on earth as it provides food and oxygen to various organism.

Answer:

Weight is the measure of the force of gravity on an object. The mass of an object will never change, but the weight of an item can change based on its location. For example, you may weigh 100 pounds on Earth, but in outer space you would be weightless.

Sodium chloride can be produced by the reaction of sodium metal with chlorine gas. Which is the limiting reactant if 6.70 moles

Alecsey [184]

Answer:

Chlorine gas.

Explanation:

Hello!

In this case, the undergoing chemical reaction is:

$2Na+Cl_2\rightarrow 2NaCl$

Thus, given the moles of reacting both sodium and chlorine, we compute the moles of sodium chloride yielded by each reactant by considering the 2:2 and 1:2 mole ratios:

$n_{NaCl}^{by\ Na}=6.70molNa*\frac{2molNaCl}{2molNa}=6.70molNaCl \\\\n_{NaCl}^{by\ Cl_2}=3.20molCl_2*\frac{2molNaCl}{1molCl_2}=6.40molNaCl$

Thus, since chlorine yields less moles of sodium chloride, we infer it is the limiting reactant.

Best regards!
