The correct answer is option (B) Two molecules of H2 and a molecule of O2 must collide at one time

Explanation:

2H2(g) + O2(g) → 2 H2O(g)

   2             1            2

Considering the given reaction, for water molecule to be form, two molecules of hydrogen and one molecule of oxygen must collide at the same time. The product obtained from the collision is two molecules of water as steam. 2 H2O(g)

Scientists observe that iron compounds are able to bind to nutrients in waterways experiencing eutrophication. Which change will
Anettt [7]

(1) Fewer microorganisms will grow on the surface of the lake if iron compounds are added to a lake with an overabundance of nutrients. Hence, option 1 is correct.

(2) Fracking means using water and chemicals at high pressure to open up fissures to access oil and gas resources. Hence, option 2 is correct.

<h3>What are microorganisms?</h3>

An organism that can be seen only through a microscope.

Iron is a natural capping agent which can enhance sediment P binding capacity, thus reducing P availability and shifting a lake from an algal to a macrophyte dominated state. Iron could, however, also impose toxic effects on the biota.

Fracking is the injection of a fluid at high pressure into an underground rock formation to open fissures and allow trapped gas or crude oil to flow through a pipe to a wellhead at the surface.

This technique is used in natural gas and petroleum production.

1) Fewer microorganisms will grow on the surface of the lake if iron compounds are added to a lake with an overabundance of nutrients. Hence, option 1 is correct.

(2) Fracking means using water and chemicals at high pressure to open up fissures to access oil and gas resources. Hence, option 2 is correct

2. How much force will this car experience if it collides with a wall and the collision lasts for
Pepsi [2]

The momentum of the body is 12 m/s.

<h3>What is momentum?</h3>

Momentum is the product of the mass of a body and velocity. According to Newton's second law, the rate  of change of momentum is equal to the impressed force.

The details required to answer the first two questions are missing hence we can't answer those questions. For the last question;

p = mv

m = mass

v = velocity

p = momentum

v = p/m

v =  72,000 kgm/s/6,000 kg

v = 12 m/s
