Answer:

Explanation:

Look at change in concentration over time...is it increasing or decreasing? It is increasing right as you can see because it starts at 0 then increases and plataeus. What increases in a reaction, reactant or product? Products increase right cuz your reactants react with each other to make prodcuts.

At start of reaction you have no products (zero) thus this graph starts at 0. At end you have alot of product thus over time the concentration of product increases.

ABC are reactants their concentration should decrease over time

DE are products, they should increase as reaction goes on.

Balance each reaction and write its reaction quotient, Qc:(a) NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

AleksAgata [21]

When we balance the given equation

NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We will get

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

Solution:

Balancing the given equation

NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We have to balance the number of Cl

2NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We have to balance the number of N, O.

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

We will get the balanced equation

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

The reaction quotient will be

Qc = [product] / [reactant]

Qc = [NO₂(g) + Cl₂(g)] / [NO₂Cl(g)]

1.4 Explain why it is important to support individuals to challenge information about services that may present a barrier to par

Marizza181 [45]

So, as I understand it, we're talking about faulty information, one that is limiting people's access to certain services. An example of such information is the denial of an interpreter service for the Deaf. If someone is spreading the information that such a service is not available, even if is, then when someone challenges this information, they should be supported.

The mixture which contains elements only is (a) air (b) brass (c) mineral water (d) seawater

Sholpan [36]

Answer:

So yes! A mixture can contain just elements if those elements are not chemically reactive to one another. Air is a great example of an elemental mixture as it contains nitrogen, oxygen, and argon (along with some other compounds).

brilliants [131]

Answer:

16.92 g C13H18O2

Explanation:

If the molecular mass of C13H18O2 is 206.3 amu, then molar mass of C13H18O2 is 206. 3 g/mol.

So, if we have 0.082 mol C13H18O2, than it is

206.3 g/mol*0.082 mol = 16.92 g C13H18O2.
