Identify the statements that are correct. Check all that apply. View Available Hint(s)for Part A The mass ratio of oxygen to carbon in CO is twice the mass ratio of oxygen to carbon in CO2. For two compounds of C and O, the mass ratio of C to O in one compound is a multiple of the mass ratio of C to O in the other compound or can be converted to a small whole number ratio. The mass ratio of oxygen to carbon in CO2 is 2.667 for every sample of CO2. The mass ratio of oxygen to carbon in CO is 1.33 for every sample of CO.

The correct statement is; For two compounds of C and O, the mass ratio of C to O in one compound is a multiple of the mass ratio of C to O in the other compound or can be converted to a small whole number ratio.
According to the law of multiple proportions, if two elements say, A and B combine to form more than one chemical compound; the various masses of one element, A, which combine with a fixed mass of the other element B are in simple ratio.
This means that, if there are two compounds of elements like C and O (as in CO and CO2), the mass ratio of C to O in one compound is a multiple of the mass ratio of C to O in the other compound or can be converted to a small whole number ratio.

1) Plants need water for______in order to make food. water is needed more for _____, to maintain body temperature and transport nutrients.
Answers
Answer:
Hi Lovelys!!
Answer down below!!
Explanation:
Answer: Plants need water for photosynthesis in order to make food. Water is needed more for cooling, to maintain body temperature and transport nutrients.
Reason: Plants need water for photosynthesis. Water also helps move nutrients from the soil into the plant. Too little water can cause a plant to wilt or droop. Too much water can cause a plant's roots to rot. Plants are about 80-95% water and need water for multiple reasons as they grow including for photosynthesis, for cooling, and to transport minerals and nutrients from the soil and into the plant.

a compound is made up of 56.34% oxygen and phosphorus.state the empirical formula and name the compound
Answers
Answer:
An interesting way to approach this problem is to determine the oxide's molecular formula first, then backtrack and find its empirical formula.
So, you know that this oxide of phosphorus has a molar mass of
284 g mol
−
1
. This tells you that one mole of this oxide has a mass of
284 g
.
You also know that the oxide has a percent composition of
43.66
%
phosphorus and
56.34%
oxygen.
This means that every
100 g
of oxide will contain
43.66 g
→
phosphorus,
P
56.34 g
→
oxygen,
O
Pick a
284-g
sample of this oxide, which will be equivalent to one mole, and determine how many moles of each constituent element it contains. This will get you the compound's molecular formula.
So, you can say that this sample will contain
284
g oxide
⋅
43.66 g P
100
g oxide
=
123.994 g P
284
g oxide
⋅
56.34 g O
100
g oxide
=
160.006 g O
Use the molar masses of the two elements to convert the masses to moles
For P:
123.994
g
⋅
1 mole P
30.9738
g
=
4.003
≈
4 moles P
For O:
160.006
g
⋅
1 mole O
15.9994
g
=
10.001
≈
10 moles O
Since this is how many moles of phosphorus and oxygen you get in one mole of the oxide, it follows that its molecular formula will be

A scientist is working in a lab and accidentally combines two liquids that quickly form a solution. Which process could be used to separate the two liquids?
Answers
Answer:
Distillation
Explanation:
The method of distillation can be used to separate the two liquids, if their boiling point is known. The liquid with lower boiling point will be evaporated and its vapours will be captured, while the liquid with higher boiling point will remail in the container in the liquid state.
The process that could be used to separate the two liquids is heating the liquids and letting one boil away first. The correct option is A.
What is liquid?The liquid is one of the states of matter. The liquid has molecules that are nearer than gas. The liquid does not have a specific shape and size. They acquire the shape of the container in which they are poured.
When the liquid is boiling and the molecules of the liquid convert into vapor. The molecules of liquid go far away from each other. When the temperature increased, boiling happened. The process will be heating the liquids and letting one boil away first.
Thus, the correct option is A. heating the liquids and letting one boil away first.

The speed of sound through air is approximately 343 m/s. What is the speed in
miles per hour? 1 ft = 0.3048 m; 1 mile = 5280 feet
Answers
Answer:
343m/s= 767.26...mph
Explanation:
First we convert meters to feet.
343m = 1125.32ft
Next, we convert feet to miles.
1125.32ft = 0.2131288 miles
Finally, we convert 0.2131288 miles per second into mph. Since there's 3600 seconds in an hour, we multiply 0.2131288 by 3600.
0.2131288 x 3600 = 767.26368...

A ball hits a wall. What is true about the magnitude of the force experienced by the ball compared with the force experienced by the wall?
ОА.
The ball experiences more force than the wall.
OB. The ball experiences less force than the wall.
O c.
The ball and the wall experience the same force.
OD
The ball experiences half the force of the wall.
Answers
According to Newton's 3rd Law of motion, each force has an equal and opposite reaction force. Although this concept is sometimes confused because people often mistake force for the action of the ball and wall after the collision. Of course, the ball will bounce back and the wall will stay still, but that has to do with collisions, not the force on the objects. So the answer is C.

What is the formula mass of a compound with 2 aluminum atoms and 3 oxygen atoms?
Answers
Answer:
[tex]\boxed {\boxed {\sf 101.96 \ amu}}[/tex]
Explanation:
Formula mass is the sum of the atomic masses of the atoms in a molecule. Essentially, it is the mass of 1 molecule of a compound.
We are given a compound containing 2 aluminum atoms and 3 oxygen atoms. We will use the Periodic Table to look up the atomic masses of the 2 elements in the compound.
Al: 26.981538 amuO: 15.999 amuThese are the atomic masses of 1 atom of the element. Remember we have 2 Al atoms and 3 O atoms. We multiply the element's atomic mass by the number of atoms of that element in the compound.
2 Al: 26.981538 amu *2= 53.963076 amu 3 O: 15.999 amu * 3=47.997 amuNow we add the atomic mass of 2 Al atoms and 3 O atoms.
53.963076 amu + 47.997 amu = 101.960076 amuWe may want to round this answer to the hundredth place. The 0 in the thousandth place tells us to leave the 6 in the hundredth place.
101.96 amuThe formula mass of a compound with 2 aluminum atoms and 3 oxygen atoms is approximately 101.96 atomic mass units.
