Gwar [14]

Answer:

The planets follow these orbit  paths as they travel around the Sun. The Sun’s gravity  

makes the planets move in this way. It pulls on the planets, keeping them in motion in their orbit.

Modeling is a way to see ideas or have a  particular idea or

concept.

 Models do have some lines .

 Often a model is made with certain things.

 A model of the solar system may contain all of the planets and the Sun, but it may not include the planets’

individual moons or every planit  and rock in the solar system.

Explanation: if you think about it and and look at pics it is easy

S_A_V [24]

Answer:

Rainfall - precipitation

disappeared puddles - evaporation

cloud formation - condensation

Rainfall that is observed by the Susan is the precipitation of the water cycle in which the water vapor that was condensed become heavy and form droplets of water and fall from sky to the earth surface.

Puddles that formed due to rainfall are the collection of water in the water cycle which is evaporated (process: evaporation) into the atmosphere n the form of water vapor which condensed to form clouds.

Solution A is 0.44 M and reacts with 0.11 M of solution B. Assume that the value of x is 0, the value of y is 1, and r is 1.07 ×
xz_007 [3.2K]

Answer:

K, the rate constant = 9.73 × 10^(-1)/s

Explanation:

r = K × [A]^x × [B]^y

r = Rate = 1.07 × 10^(-1)/s

K = Rate constant

A and B = Concentration in mol/dm^-3

A = 0.44M

B = 0.11M

x = Order of reaction with respect to A = 0

y = Order of reaction with respect to B = 1

Solving, we get

r/([A]^x × [B]^y) = K

K = 1.07 × 10^(-1)/s/(0.44^0 × 0.11^1)= 0.9727

K = 0.9727
