The solution will be acidic if it contains a greater concentration of hydronium ions and acidic if it contains a greater concentration of hydrogen ions. So High concentrations of hydrogen lead to low pH(acidic) whereas low levels of hydrogen ions result in in a high pH(basic)
Answer:
1. d. 84g
2. c. 77.4%
Explanation:
1. Based on the reaction 2 moles of Na produce 2 moles of NaCl.
The moles of Na (22.99g/mol) in 33g are:
33g * (1mol / 22.99g) = 1.435 moles Na = 1.435 moles NaCl must be produced.
The mass of NaCl is (Molar mass: 58.44g/mol):
1.435moles * (58.44g / mol) = 84g
d. 84g
2. Percent yield is defined as 100 times the ratio between actual yield (65g) and theoretical yield (84g). The percent yield is:
65g / 84g * 100 =
c. 77.4%
Answer:
The Kelvin temperature scale reflects the relationship between temperature and average kinetic energy.
Explanation:
The Kelvin temperature of a substance is directly equal to the average kinetic energy of the particles of a substance.
Answer:
Carbonated water is a mixture,
Explanation:
which means it contains two or more different chemicals.
Is Sodium Hydroxide an element, mixture, or compound?
An example would be placing sodium (Na) in water (H2O). Sodium creates a new chemical bond producing a new substance with new physical and chemical properties known as sodium hydroxide (NaOH). So, if a new chemical formula must be written after two or more substances combine it is not a mixture.
