Carlos is making phosphorus trichloride using the equation below.

Chemistry
1 answer:
hjlf1 year ago
7 0

Answer:

C.) 2

Explanation:

Chemical equations, in a way, can be seen as algebraic equations. Cl2 is a molecular structure, so, there are two Cl atoms. 3Cl2 means 3, Cl2 molecules. So, if we think of it as adding up all the atoms, we will get, 2 P atoms and 6 Cl atoms. Now to convert. The Law of the Conservation of Mass basically says you can't add or subtract atoms out of nowhere, so the number of atoms has to stay the same when it's being converted. We need to place a coefficient with PCl3. If we look at PCl3, it shows us that there are three Cl atoms and one P atom. And looking back at how many atoms there were on the left side of the equation, we just need to double the atoms of atoms so it will be equal. So, the answer is C.) 2

Covalent compounds occur------
irga5000 [103]

Answer:

Only between nonmetals

Explanation:

  • Covalent compounds are compounds that are formed as a result of covalent bonding between nonmetal atoms.
  • Covalent compounds occur only between non metals, where atoms of the nonmetals involved join to form a covalent bond as a result of sharing of electrons.
  • <u><em>Electrons shared during the formation of covalent bond, may be from one atom involved or each atom contributing equally to the bond formation.</em></u>
  • An example of covalent compounds include, phosphorus (v) oxide, methane, water, CO2,etc.

WORTH 80 POINTS PLEASE HELP
Verdich [7]

The two bulges are called tidal bulges. There are two tidal bulges on opposite sides of Earth. One is beneath the moon and the other is opposite to that. The one below the moon is thought of as gravitational. It is produced by gravitational attraction between water molecules in the ocean and the moon.

<span>Now, about the other bulge. Think about inertia and what happens when masses rotate around a single point. Imagine yourself swinging a bucket of any liquid with your arm in a circular gesture. Even as the bucket goes over your head, the water is still held in the bucket and doesn't splash all over you. This rotation creates a centrifugal force. A similar event occurs during the lunar month as the earth/moon system rotates. The moon orbits the earth, but the rotation axis for this orbit isn't earth's center. Both the moon and Earth move during the roughly 28-day period it takes for the orbit, and because of this, water in the ocean is thrown to the outside, the same as the water in your bucket. The tidal bulge on the opposite side of Earth from the moon is produced by this inertial effect, referred to as centrifugal force.</span>

Manganese sulfate forms a pale pink hydrate with the formula MnSO 4 ⋅ n H 2 O ( s ) . If this hydrate is heated to a high enough
Mama L [17]

Answer:

Value of n in MnSO₄.nH₂O is one.

Explanation:

The n represents the number of moles of water attached to the formula unit manganese sulfate. These moles (n) can be determined by taking the ratio of the moles of anhydrous salt and the moles of water. The moles of water can be determined by taking the difference of final and initial mass of the salt. This difference is equal to the mass of the water, mathematically it can be represented as,

Mass of H₂O = initial mass of the salt (g) - final mass of the salt (g)

Mass of H₂O = 16.260 g - 14.527 g

Mass of H₂O = 1.733 g

moles of H₂O = (1.733 g) ÷ (18.015 g/mole)

moles of H₂O =  0.0962

For the moles of anhydrous salt:

moles of MnSO₄ = mass of MnSO₄ ÷ molar mass of MnSO₄

moles of MnSO₄ = 14.5277 ÷ 151.001

moles of MnSO₄= 0.0962

Now for n:

n = moles of water ÷ moles of MnSO₄

n = 0.0962 ÷ 0.0962

n = 1

The above calculations show that one mole of H₂O is attached to the  one formula unit of MnSO₄
