How would a flood be a limitation for synthetic polymers that rely on natural rubber in its production?

Answers

Answer:

A flood would affect the availability of a material used in making a synthetic polymer. If a flood destroys rubber trees, the availability of natural rubber would decrease, which would in turn decrease the production of synthetic polymers.

Explanation: I just did it

Answer: Sample Response: A flood would affect the availability of a material used in making a synthetic polymer. If a flood destroys rubber trees, the availability of natural rubber would decrease, which would in turn decrease the production of synthetic polymers.

What is the mole to mole ratio between nitrogen gas and hydrogen gas

Answers

Answer : The moles ratio between the nitrogen gas and hydrogen gas are, 1 : 3 respectively.

Explanation :

The balanced chemical reaction will be,

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$

Mole ratio : It is defined as the ratio of the number of moles of the substances whose ratio is to be calculated.

In a chemical reaction, the stoichiometric coefficients represents the number of moles.

By stoichiometry of the reaction we can say that,

1 mole of nitrogen gas reacts with 3 moles of hydrogen gas to produce 2 moles of ammonia gas.

Hence, the mole ratio of between the nitrogen gas and hydrogen gas are, 1 : 3 respectively.

For instance you have a chemical reaction of N2 + 3H2 -> 2NH3. The number of moles of N2 is 1, H2 is 3 and NH3 is 2. The mole to mole ratio between nitrogen gas and hydrogen gas is 1/3 or 1 is to 3.

Josh prepares a solution by mixing sodium nitrate and water. To calculate the molarity of the solution, Josh should calculate the moles of which substance, and why?sodium nitrate, because it is the solvent
sodium nitrate, because it is the solute
water, because it is the solvent
water, because it is the solute

Answers

Answer:

sodium nitrate, because it is the solute

Explanation:

To find the molarity of the solution, Josh should determine the number of moles of the sodium nitrate.

Molarity is defined as the number of moles of solutes in a given volume of solution.

Molarity = $(n)/(v)$

n is the number of moles of solute

v is the volume of solution

Answer:

C: sodium nitrate, because it is the solute
