Answer: 55
Explanation: A atom consists of a nucleus and electrons.Nucleus contain neutrons with no charge and protons with positive charge. The electrons bearing negative charge revolve around the nucleus.
An electrically neutral atom contains equal number of protons and electrons. Thus if a neutral element X contains 55 protons, it also contains 55 electrons.
Answer:
30.8 grams of nitric acid are produced
Explanation:
Let's state the reaction:
3 NO₂ + H₂O → 2 HNO₃ + NO
If water is the excess reagent, then the limiting is the gas.
We convert the mass to moles:
45 g . 1 mol/ 46 g = 0.978 moles
Ratio is 3:2. 3 moles of gas can produce 2 moles of acid
Then, 0.978 moles may produce (0.978 . 2) /3 = 0.652 moles of acid
This is the 100% yield, but in this case, the percent yield is 75%
0.652 moles . 0.75 = 0.489 moles
Let's convert the moles to mass → 0.489 mol . 63g / 1mol = 30.8 g
Answer:
Is an exemplar of Italian Renaissance painting.
Explanation:
the Kingdom to St. Peter is an exemplar of Italian Renaissance painting. The work was part of a large decorative program commissioned by Pope Sixtus IV in 1481 for the walls of the Sistine Chapel (the name “Sistine” being derived from Sixtus’ own name), which was then, as it is today, the pope’s private chapel in the Vatican, in Rome.
