Answer:
The correct answer is option a.
Explanation:
When aluminum hydroxide reacts with of nitrous acid it gives of aluminum nitrite and of water.
According to above reaction ,when 1 mole of aluminum hydroxide reacts with 3 moles of nitrous acid it gives 1 mole of aluminum nitrite and 3 moles of water.
Hence, the correct answer is option a.
The characteristic of the Bohr model that would best support his observation is this assumption: "The energy of the electron in an orbit is proportional to its distance from the nucleus. The further the electron is from the nucleus, the more energy it has." The discrete, bright, colored lines might represent the electrons and its distance from the nucleus. The lights are caused by the energy it has.
Answer is (3) protons and neutrons.
(P.S. The outer part contains the electrons)
The grams of sodium chloride that will be made is 292.5 g
<u><em>calculation</em></u>
2Na +Cl₂ → 2NaCl
step 1: calculate the moles of Na
moles = mass/molar mass
From periodic table the molar mass of Na = 23 g/mol
moles = 115 g/23 g /mol = 5 moles
Step 2 : use the mole ratio to determine the moles of NaCl
Na:NaCl is 2:2 = 1:1 therefore the moles of NaCl is also= 5 moles
Step 3: find the mass of NaCl
mass= moles x molar mass
The molar mass of NaCl = 23 + 35 .5 =58.5 g/mol
mass= 5 moles x 58.5 g/mol =292.5 g
Answer:
c. stays the same, changes
Explanation:
temperature and heat go hand in hand, however while the change of state occurs, the temperature remains the same while the heat increases since the heat input is constant.
