Answer:
The blanks can be completed with words in the following sequence
1) elements
compound
2) atom
3) matter
4) compound
5) chemistry
6) reactants
product
Explanation:
In H2SO4, atoms of hydrogen, sulphur and oxygen represent different elements that are combined to form the compound.
The smallest indivisible unit of matter that still retains all the properties of matter is an atom. Matter is anything that has weight and occupy space.
Atoms combine in fixed ratios to form compounds. Chemistry studies matter scientifically and pays specific attention to the changes that matter undergoes.
Considering the reaction of photosynthesis, water and carbon dioxide combine to give glucose so the water and carbon dioxide are reactants while the glucose is the product of the reaction.
Answer:
The bolts will run out first, so these will limit how much product can be formed.
(option C is correct)
Explanation:
Step 1: Data given
Number of bolts = 5
Number of nuts = 12
ratio N:B = 2:1
Step 2
Since the ratio N:B is 2:1 we have 2 nuts for each bolt
When we have 2 bolts we have 4 nuts
When we have 3 bolts we have 6 nuts
When we have 4 bolts we have 8 nuts
When we have 5 bolts we have 10 nuts
We don't have more bolts, but there are still 2 nuts left. This means the bolts will run out first, so these will limit how much product can be formed.
(option C is correct)
Answer:
It's false.
Explanation:
Molecular orbital theory states that the number of molecular orbitals is equal to the number of atomic orbitals that overlap. The lowest energy molecular orbital is formed when two atomic orbitals that are in phase overlap, forming a bonding molecular orbital. However, another molecular orbital is also formed, called an anti-binding orbital.
So if an "n" quantity of atomic orbitals is combined, an "n" quantity of molecular orbitals is formed.
Have a nice day!
Answer:
63.36gallons
Explanation:
Given:
Volume of water used for dialysis = 2.4 x 10²L
Solution:
We are to convert from liters to gallons.
The conversion factor is shown below:
1L = 0.264gallons
To convert to litre:
since 1L = 0.264gallons
2.4 x 10²L = (2.4 x 10² x 0.264)gallons; 63.36gallons
Answer:
It should be silicon... I even googled it to see if I was correct and that’s what it says so can someone figure out why silicon is not an answer
