How many moles of H2O are produced from 3 moles of oxygen? 2H2 + O2 --> 2H2O
Answer: 6 mol
Explanation:
From the equation, we know that for every mole of oxygen consumed, 2 moles of water are produced.
This means that if 3 moles of oxygen are consumed, 3(2) = 6 mol of water are produced.

Explanation:
What is the fixer solution equation?
Answer:
Fixation involves these chemical reactions (X = halide, typically Br−): AgX + 2 S2O32− → [Ag(S2O3)2]3− + X. AgX + 3 S2O32− → [Ag(S2O3)3]5− + X. In addition to thiosulphate the fixer typically contains mildly acidic compounds to adjust the pH and suppress trace amounts of the developer.
Which two processes of the water cycle absorb energy from the Sun?
A evaporation and precipitation B sublimation and evaporation C condensation and transpiration D precipitation and condensation
Answer: of Earth's atmosphere occurs as energy, primarily from the sun, causes liquid water to transform to another phase. As this occurs, liquid water absorbs energy, causing it to evaporate and form water vapor. The process of evaporation absorbs tremendous amounts of incoming solar energy.
Explanation:
Water absorbs energy when it undergoes___
A. freezing
B. deposition
C. condensation
D. melting
Answer:
d. melting

How many moles of gallium chlorate, Ga(ClO3)3, must react in order to produce 674 kJ of energy according to the following reaction? 2 Ga(ClO3)3 à 2 GaCl3 + 9 O2 DH = - 130.4 kJ
Answer:
10.3 mol Ga(ClO₃)₃
Explanation:
Let's consider the following balanced thermochemical equation.
2 Ga(ClO₃)₃(s) ⇒ 2 GaCl₃(s) + 9 O₂(s) ΔH = - 130.4 kJ
According to the balanced thermochemical equation, 130.4 kJ of heat are released when 2 moles of gallium chlorate react. The number of moles of gallium chlorate that must react to produce 674 kJ of energy is:
674 kJ × 2 mol Ga(ClO₃)₃/130.4 kJ = 10.3 mol Ga(ClO₃)₃
Thermochemical equations are chemically balanced equations that take into account both the energy change and the physical states of all reactants and products. Energy is a reactant in an endothermic process, whereas it is a product in an exothermic reaction. Here the moles of Ga(ClO₃)₃ is 10.3 mol.

why does solid silver, Ag, conducts electricity while solid silver chloride, AgCl, does not.
Answer: A solid silver, Ag, conducts electricity because it contains ions or electrons while solid silver chloride, AgCl, does not conduct electricity because AgCl does not dissociate to give ions or electrons.
Explanation:
Solid silver (Ag) is considered to be a good conductor of electricity because there are more number of free electrons or movable atoms are present in it.
As electricity is the flow of ions or electrons. So, more is the number of ions or electrons present in a substance more will be its conductivity.
Whereas solid silver chloride is a precipitate that is insoluble in water and therefore, it will not give ions or electrons.
As a result, silver chloride is not able to conduct electricity.
A nebula is often made up of hydrogen and helium gases.
True
False
Answer:
Nebulae are made of dust and gases—mostly hydrogen and helium. ... Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.

A scientist is measuring the pressure that is exerted by each of the following gases in the atmosphere: carbon dioxide,
oxygen, and nitrogen. Which term most likely describes what she is measuring?
O final pressure
O atmospheric pressure
O combined pressure
O partial pressure
Answer:
D. Partial pressure
Explanation:
Partial pressure is the individual pressure exerted by each gas present in a gaseous mixture. As he is measuring the pressure of each gas in the atmosphere separately, so PARTIAL PRESSURE is the exact term for his measurement.
How much of a 60.0 gram sample of Carbon-14 DECAYED after 17,100 if 5
its half-life= 5,700 years? *
7.50 g
52.5 g
15.0 g
30.0 g
The mass of 60 g of carbon -14 remains after 17100 years is 7.50 g. Thus, option a is correct.
What is radioactive decay?The unstable isotopes of atoms undergo radioactive decay by the emission of charged particles. The radioactive decay is a first order reaction.
The rate constant k = 1/t ln (M0/Mt)
where, M0 and Mt be the initial mass and mass after t respectively.
Given the initial mass = 60 g
half life t1/2 = 5700 years.
decay constant k = 0.693 / t1/2
= 0.693 / 5700 = 0.00012 yr⁻¹
Apply the values in the first order rate constant equation as follows:
0.00012 yr⁻¹ = 1/ (17100 yrs) ln (60/Mt)
60/Mt = 7.996
Mt = 7.50 g.
Therefore, the mass of the mass of 60 g of carbon -14 remains after 17100 years would be 7.50 g.

What can be different between the products and reactants in a balanced chemical equation?
Answer:Reactants are starting materials and are written on the left-hand side of the equation. Products are the end-result of the reaction and are written on the right-hand side of the equation.
Explanation:
The reactants in a balanced chemical reaction are the starting material which reacts together to give the products in by the regrouping of atoms in the reactants.
What is a balanced chemical equation?The balanced chemical equation of a reaction represents the perfect stoichiometry of each reactants and products with their states of matter in brackets.
In a balanced reaction, the number of each element in the reactant side must be equal to their number in the product side. The number of each elements and groups in a reaction can be balanced by multiplying with suitable integers.
The atoms in the reactants are regrouping to form the products. Thus, the identity of the new products is entirely different form that of reactants in the reaction.
