A major cause of biodiversity loss and species extinction in North Caroline is due to the introduction of invasive non-native sp

ecies in the ecosystem. Many invasive species come for the similar climatic conditions where they can thrive, but most arrive by human transport on accident or on purpose. Some examples include: Bradford pears, Japanese honeysuckle, Asian carp, and brown tree snake.
What is NOT an impact that an invasive non-native species has on an ecosystem?

A) destroying habitats

B) prey on native species

C) destroying food sources

D) increases reproduction of native species

Answer:

The option<u><em> D)  increases reproduction of native species</em></u> is NOT an impact that an invasive non-native species has on an ecosystem.

Explanation:

Introduction of a non-native species into a stable ecosystem can be very threatful to the ecosystem. The non-native species will compete for resources with the native species of the area. As a result, there will be severe competition. The competition might lead to migration of the native species or them being endangered on the whole. Also, the introduction of a non-native species will result in the extinction of a particular prey as it will have an increase in the number of predators.

Answer: 0.422 M⁻¹s⁻¹

Explanation: <u>Reaction</u> <u>Rate</u> is the speed of decomposition of the reactant(s) per unit of time.

A <u>Rate</u> <u>Law</u> relates concentration of reactants, rate reaction and rate constant:

r=k[A]^{x}[B]^{y}

where

[A] and [B] are reactants concentration

x and y are reaction order, not related to the stoichiometric coefficients

k is rate constant

r is rate

Before calculating rate constant, first we have to determine reaction order.

In this question, the reactio order is 2. So, the rate law for it is

-\frac{d[A]}{dt} =k[A]^{2}

and the integrated formula is

\frac{1}{[A]} =\frac{1}{[A]_{0}} +kt

in which

[A]₀ is initial concentration of reactant

Then, using initial concentration at initial time and final concentration at final time:

\frac{1}{0.031} =\frac{1}{0.065} +k(40)

40k=\frac{1}{0.031}-\frac{1}{0.065}

40k=32.26-15.38

k = 0.422

The rate constant for the reaction is 0.422 M⁻¹.s⁻¹

A student carefully drops a 9.0 g solid Zn pellet initially at 50.0°C into an insulated cup containing 30.0 g of water at 27.8°C
jekas [21]

Answer: choice B

Explanation: Heat flows from high to low. After you convert the Celsius into kelvin the Zn pellet has 323K and the water has 301K which results the transfer of the heat energy of the pallet to the water. ( you don’t have to convert, but it just make it easier) hope this helped you :)

Use the reaction shown l to answer these questions.
Varvara68 [4.7K]

Answer:

16.8dm3

Explanation:

2 moles of CO gives 1 mole of N2

2 moles of CO= 2* 28= 56g

1 mole of N2 = 1* 22.4dm

56g of CO gives 22.4dm3 of N2

42.7 of CO will give> (42.7*22.4)/56

=16.8dm3
