Why does it make sense that if an atom loses electrons, it is left with a positive charge?
rosijanka [135]
Electrons are negatively charged. If you remove negative particles, the leftover atom is positive and positive is really just another word for "less negative".

What is the mass of silver (107.87 g/mol) produced by the reaction of 3.00 moles of copper with 3.00 moles of silver nitrate?Cu
vladimir2022 [97]

Answer: 323.61 g of Ag will be produced

Explanation:

The given balanced chemical reaction is :

Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag

According to stoichiometry :

2 moles of AgNO_3 require 1 mole of Cu

Thus 3.00 moles of  AgNO_3 will require=\frac{1}{2}\times 3.00=1.50moles  of Cu

Thus AgNO_3 is the limiting reagent as it limits the formation of product.

As 2 moles of AgNO_3 give =  2 moles of Ag

Thus 3.00 moles of AgNO_3 give =\frac{2}{2}\times 3.00=3.00moles  of Ag

Mass of Ag=moles\times {\text {Molar mass}}=3.00moles\times 107.87g/mol=323.61g

Thus 323.61 g of Ag will be produced from the given moles of both reactants.

is carried out adiabatically in a constant-volume batch reactor. The rate law is Plot and analyze the conversion, temperature, a
Sphinxa [80]

Answer:

See explaination

Explanation:

The mole balance for a constant-volume batch reactor is given such as, For a first-order isothermal reaction, the time to reach a given conversion is the same for constant-pressure and constant-volume reactors. Also, the time is the same for a reaction of any order if there is no change in the number of moles.

Please kindly check attachment for the step by step solution of the given problem.

A 150 mL sample of hydrochloric acid (HCl) completely reacted with 60. 0 mL of a 0. 100 M NaOH solution. The equation for the re
SSSSS [86.1K]

Answer:

The balanced chemical reaction is expressed as:

HCl + NaOH ---> NaCl + H2O

We are given the amount and the concentration of the sodium hydroxide reactant. This will be the starting point for the calculations.

0.100 mol NaOH/L solution (0.06 L solution) ( 1 mol HCl / 1 mol NaOH) = 0.006 mol HCl

Molarity = amount in moles / Volume of solution = 0.006 mol HCl/ 0.150 L

Molarity = 0.04 M
