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.

How many moles of oxygen gas are there in 395 L of oxygen at STP?
kozerog [31]

Answer:

17.6 moles of oxygen gas.

Explanation:

STP Variables:

P=1 atm

R=0.082

T=273 K

Use the PV=nRT, then plug in.

n=PV/RT

n= (1 atm)(395 L)/(0.082) (273 K)

Simplify.

n=17.6 moles of O2

Hoped this helped.

Plzz someone help me ASAP!
irina1246 [14]

The greater the friction, or rubbing, between particles in any fluid, the higher the viscosity. A fluid with a high viscosity has a large amount of internal friction. As the temperature of a gas increases, friction increases, and so the viscosity of the gas increases. The warmer the gas, the slower it flows.

PLEASE SHOW WORK and inlcude units on each number
Sedbober [7]

 The  limiting  reagent  is   <u>H₂SO₄</u>

   <u><em>calculation</em></u>

<u><em> </em></u>Step 1 :write the equation for reaction

2 NaOH + H₂SO₄  → Na₂SO₄   + 2 H₂O

Step  2: use the mole ratio to determine the  moles of product  produced from each reactant

that is   from  equation above,

NaOH : Na₂SO₄  is 2 :1 therefore the  moles of Na₂So₄

= 10.0 moles x 1/2 =  5.0 moles

H₂SO₄ :Na₂SO₄  is 1:1 therefore the moles  of Na₂SO₄  is also = 3.50 moles


H₂SO₄  is the limiting reagent since  it produces  less amount of Na₂SO₄
