Answer:

True

Explanation:

An energy diagram for a chemical reaction is an energy vs. reaction coordinate graph that informs how a reaction is carried out in terms of the energy of the reactants, products, and intermediate states.

The reactants are drawn on the left, since initially the energy they possess is described in the diagram, followed by the different transition states where bonds are broken or formed, to give rise to the products, which are generally drawn on the right.

Answer:

44.9g

Explanation:

You have to convert grams of CH4 to moles, use the mole-to-mole ratio of CH4 to water, and convert back to grams.

(20.0g CH4)(1 mol CH4/16.04g)(2 mol H2O/1 mol CH4)(18.01 g H2O/ 1 mol) = 44.9127 g

Hope this helps!

Uranium has atomic number 92. Its most common isotope is 238U, but the form used in nuclear bombs and nuclear power plants is 23
Yakvenalex [24]

Explanation:

Atomic Number = Number of protons

Mass Number = Number of protons + Number of neutrons

Isotopes are simply atoms of an element with the same number of protons and different number of neutrons.

First Isotope -- 238U

Number of neutrons = Mass Number - Atomic Number

Number of neutrons =  238 - 92 = 146

Second Isotope -- 235U

Number of neutrons = Mass Number - Atomic Number

Number of neutrons =  235 - 92 = 143

In which of these samples do atoms have the greatest kinetic energy
shepuryov [24]

Answer is: atoms have the greatest kinetic energy in liquid iron (2,000°C).

The average kinetic energy of molecules depends on the temperature. 

At high temperature(2,000°C), molecules of iron have greater kinetic energy than molecules of iron at low temperature (1,600°C, 65°C and 25°C)..
