I think the correct answer from the choices listed above is the last option. The balanced chemical equation for the synthesis of NaBr from Na and Br2 would be <span>2Na + Br2 —> 2NaBr. It should be that the number of atoms in the reactant and in the product side is equal. Hope this answers the question.</span>

Answer: The correct option is:

2Na+Br_2\rightarrow 2NaBr

Explanation:

In balanced chemical equation , mass of the reactants is always equal to the mass of the products.

2Na+Br_2\rightarrow 2NaBr

This is the balanced equation because on both sides number of sodium and bromine atoms are same.

On the reactant side there are two sodium atoms and two bromine atoms

On the product side there are also two sodium atoms and two bromine atoms in NaBr.

Mass of reactants (here 2Na and Br_2)= Mass of products(here 2NaBr)

2(23u) + 2(79.9u) = 2(23u + 79.9u) = 205 u

Answer:

<h3>The answer is 11 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 3025 g

volume = 275 mL

We have

density =  \frac{3025}{275}  \\

We have the final answer as

<h3>11 g/mL</h3>

Hope this helps you

KATRIN_1 [288]
<span>(2.09 mL) x (1.592 g/mL) / (227.0871 g C3H5O9N3/mol) = 0.014652 mole C3H5O9N 4 moles C3H5O9N produce 12 + 6 + 1 + 10 = 29 moles of gases, so: (0.014652 mole C3H5O9N) x (29/4) = 0.106 mole of gases (b) (0.106 mol) x (46 L/mol) = 4.88 L gases (c) (0.014652 mole C3H5O9N) x (6/4) x (28.0134 g/mol) = 0.616 g N2</span>

Which of these describes an exothermic reaction?
Paul [167]

A nswer: -

C. Energy is released by the reaction

Explanation:-

An exothermic reaction is one in which during the progress of the reaction heat is evolved.

So energy is released by the reaction.

It cannot be created as energy is neither created nor destroyed as per the Law of conservation of energy. Energy is not transferred either.

The energy released during the progress of the reaction originates from the chemical bonds of the reactants as they break during their conversion into products.
