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)
Billions of years ago, according to the theory of evolution, chemicals randomly organized themselves into a self-replicating molecule. This spark of life was the seed of every living thing we see today (as well as those we no longer see, like dinosaurs). That simplest life form, through the processes of mutation and natural selection, has been shaped into every living species on the planet.
Answer:
68 g
Explanation:
Molar mass (C10H16) = 10*12.0 g/mol + 16*1.0 g/mol = (120+16)g/mol =
= 136 g/mol
m (C10H16) = n(C10H16)*M(C10H16) = 0.5 mol*136 g/mol = 68 g
n(C10H16) - number of moles of C10H16
M(C10H16) - molar mass of C10H16
32g of oxygen is required to burn 4g of hydrogen.
Define molecular mass.
A specific molecule's mass is expressed in daltons and is known as the molecular mass (m) (Da or u). Due to the varying isotopes of an element that they contain, multiple molecules of the same substance can have distinct molecular weights.
The total atomic mass of every atom in a molecule, calculated using a scale with hydrogen, carbon, nitrogen, and oxygen having atomic masses of 1, 12, 14, and 16, respectively. For instance, water has a molecular mass of 18 (2 + 16), which consists of two hydrogen atoms and one oxygen atom. known also as molecular weight.
In ,2H2+O2-----> 2H2O
H 2 molecules have a mass of 2 g/mol.
The molecular weight of oxygen is 32 g/mol.
When the chemical equation is balanced,
To totally react, 32 g of oxygen are needed for every 22=4 g of hydrogen.

You have to move higher; potential energy depends on height and mass.
