Answer:

so I got it wrong the first time but you should pick two points on the line such as 4,3 and 9,5. Then use the equation y^2 - y^1/ x^2 - X^1. You would get 2/5 which is D.

Bond [772]

Answer:

\%m/m=76.1\%

Explanation:

¡Hola!

En este caso, considerando la información dada, entendemos que se haría primero necesario calcular el volumen del cono en metros cúbicos, teniendo en cuenta que 0.005 km son 5 m y 300 cm son 3 m:

V=\frac{1}{3} \pi r^2h\\\\V=\frac{1}{3} \pi *(5m)^2(3m)=78.5m^3\\\\

Ahora, convertimos esta cantidad a gramos por medio de la densidad para conocer la masa de la solución:

m_{sol}=78.5m^3*\frac{1.2g}{1m^3} =94.2g

Finalmente, aplicamos la definición de %m/m para obtener:

\%m/m=\frac{300g}{300g+94.2g}*100\%\\\\ \%m/m=76.1\%

¡Saludos!

Chlorine reacts with hydrogen sul de in aqueous solution Cl2(aq) + H2S(aq) 88n S(s) + 2 H1(aq) + 2 Cl2(aq) in a second-order rea
lord [1]

Answer:

Option A

Explanation:

The knowledge of rate law is applied.

From the rate law equation ; r = K [Cl2] [H2S]

From the options, Mechanism A is quite consistent with the rate law equation

it should be noted that rate law can only be written for a slow reaction as this is the rate determining step of the reaction.

Mechanism B and Mechanism C are not consistent with the rate law equation. from the rate law equation of mechanism A, it is the only consistent one with the rate law equation as such the correct option is A.

A student wants to investigate how the beaver is differnt from most other mammals in the wild
timofeeve [1]

Answer:

I believe the options are:

a. How many other mammals eat trees or other plants to survive?

b. How many other mammals live in an environment that includes water?

c. Do most other mammals have body structures adapted to the places where they live?

d. Do most other mammals change the environment to meet their survival needs?

Explanation:

Beavers, the largest rodents in North America, are classed as a keystone species i.e their presence affects other organisms as well as the abiotic factors in an ecosystem. Beavers enhance the habitat quality of a particular region and make it habitable for other organisms.

  • Beavers build dams that form wetlands that are home to majority of species in North America.
  • They filter water from silt and increase the quality of water.
  • They are "ecological indicators" i.e. they can help establish the health status of an ecosystem.
