Answer:
SO2(g) + O2(g) SO3(g) (needs to be balanced. Balance it by placing a 1/2 in front of the 02.) This is a 5-sig-fig problem, so when you calculate your molar masses, you must use all of the sig figs available to you from the periodic table. That's how you can get this problem correct. Melissa Maribel likes to round the numbers from the periodic table, and usually that is ok. But for problems where you have many sig figs, your molar masses from the periodic table must have at least as many sig figs as your data. Therefore, for each oxygen atom, please use 15.9994 g/mol. For each sulfur atom, please use 32.066 g/mol. Thank you.
Answer:
The correct name for P₄S₃ is tetraphosphorous trisulfide or also known as phosphorous sesquisulfide.
Explanation:
P represents the element phosphorous.
S represents the element sulfur.
Since there is a 4 beside P, then we are going to use the prefix "tetra-". Since there is a 3 beside S, then we are going to use the prefix "tri-". We will also use the suffix "-ide" in sulfur because we are naming a compound with multiple elements.
So, P₄S₃ will be named tetraphosphorous trisulfide. When using more scientific terms, then the name of the compound is phosphorous sesquisulfide.
Answer:
The correct answer is number 2. Elliptical, Spiral, Irregular.
Explanation:
Unfortunately, you did not attach the passage. Without the passage, we do not know what its content is.
So we are going to answer this question with our own knowledge.
The types of galaxies by their ability to form new stars, from most to least activity are "Elliptical, Spiral, Irregular."
That is the way astronomers classify galaxies in scientific terms. These scientists consider that the smallest galaxies or dwarf galaxies have approximately 100 million stars. On the other hand, giant galaxies have billions or trillions of stars. That immense is our universe.
Scientists still studying the universe and the galaxies to understand the way galaxies are formed.
Answer:
protons : 10
electron : 10
neutron : 10
Explanation:
Protons will usually be the same as the electrons when its a <u>Atom</u> (when its a ion or covalent bond or simple bond they will most likely be different)
the atomic number represents protons and electrons
the mass number - the atomic number = neutron
If a ball is running down a ramp, why is it that when you change the height of the ramp, the ... of the ramp, then you will increase the acceleration of a ball which rolls down the ramp.
