so for this u have to use this equation where

Moles = number of particle/6.02×10^23

= 3.045 × 10^24/6.02×10^23

= 5.0581

write it to 3 S.F so 5.06 moles

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.

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.

Answer:

33.2 moles y 1994 gramos.

Explanation:

¡Hola!

En este caso, dado que es posible para nosotros relacionar moles con gramos por medio de la masa molar y moléculas con moles por medio del número de Avogadro, resulta factible para nosotros primero calcular las moles en las moléculas dadas y de esta manera luego calcular los gramos, teniendo en cuenta una masa molar de 60.05 g/mol ya que el vinagre se puede estudiar como ácido acético (CH3COOH):

[tex]2x10^{23}molec*\frac{1mol}{6.022x10^{23}molec}=33.2mol[/tex]

Seguidamente, calculamos los gramos:

[tex]33.2mol*\frac{60.05g}{1mol}=1994g[/tex]

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.

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.

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.

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.

can you answer mine i will help you! please

Explanation:

The mass of  60 g of carbon -14 remains after 17100 years is 7.50 g. Thus, option a is correct.

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.
