<span>The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. [beep] A single lap should be completed each time you hear this sound. [ding] Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark, get ready, start.</span>

During an exothermic reaction, heat content in the surroundings increases because
ANTONII [103]

Energy is transmitted to the surrounding in an exothermic reaction and this can be understood with the energy diagram of exothermic reaction attached with the answer.

<h3>What is an Exothermic Reaction ?</h3>

When a chemical reaction happens, energy is transferred to or from the surroundings.

When energy is transferred to the surroundings, this is called an exothermic reaction, and the temperature of the surroundings increases.

ΔH value negative –> energy released –> exothermic reaction

This happens because the reactants are at the higher energy state as compared to the products and therefore heat is liberated in the atmosphere to match the difference and therefore heat content in the surroundings increases.

The energy diagram for the exothermic reaction is attached with this answer.

Carbon Monoxide is a toxic gas that is colorless and tasteless. How many moles of CO are in 1 L of the gas at STP?
Debora [2.8K]

Answer:

0.045 moles

Explanation:

Given data:

Moles of CO = ?

Volume of gas = 1 L

Temperature and pressure = standard

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

n = PV/RT

n = 1 atm× 1L / 0.0821 atm.L/mol.K × 273 K

n = 1 atm.L / 22.41 atm.L/mol

n = 0.045 mol

How do you solve a double replacement reaction?
exis [7]
It’s like where two compounds positive ions which are called “Cations” remember paws for Cats paw as positive. And Negative ions which are called Anion, remember it as A Negative Ion= Anion.
And they would switch places to form a new compounds or products. Look at the Example!
